Cotopaxi Volcano Stirs, Ash Eruptions Reported

Posted by feww on August 15, 2015

Ash from Ecuadorian volcano covers parts of Quito

Two small explosions at the giant Cotopaxi volcano ejected plumes of ash to a height of about 5km above the crater on Friday, reported Ecuador’s Geophysical Institute.

Volcanic ash from the eruptions covered southern parts of Quito, Ecuador’s capital and its second most populous city [metro pop: ~ 3.2 million, FIRE-EARTH Population Model.]

The events have been described as “very small explosions” that were “almost imperceptible,” by the officials, who insist the volcano, which has been showing signs of unrest since April, with a large increase in seismicity (including harmonic tremors) and SO2 emissions, is not necessarily about to erupt.

One of the world’s highest volcanoes, Cotopaxi is located about 50 km south of Quito, Ecuador. It is the second highest summit in the Andean country, reaching a height of about 5,900m. Some 90 or so eruption have been recorded since 1534.

Colima Volcano Erupts, Hundreds Evacuated in W. Mexico

Posted by feww on July 12, 2015

Hundreds evacuated, airport closed as Colima volcano ejects large amounts of ash into the air

Colima volcano is behaving “atypically,” showing signs similar to a major eruption in 1913, said Mexico’s interior ministry.

The 1913 eruption, the largest on record since  1576, lasted for 5 days between January 20 and 24.

About 800 residents within a 12-km radius of the volcano have been evacuated. The authorities have also closed the airport in the state of Colima, due to the large amounts of volcanic ash “falling in the area,” said reports.

The volcano began erupting early Thursday and became increasingly active, spewing lava and large amounts of ash.

Colima, kla, Volcán de Fuego [“Volcano of Fire,”] is one of the most active volcanoes in Mexico. It is also potentially the most hazardous volcano in the country, with more than 300,000 people living within a 40-km radius of the mountain.

Volcanic Vent at Owakudani Valley near Tokyo Erupts

Posted by feww on June 30, 2015

Mt. Hakone erupts spewing ash and steam

A “minor volcanic eruption” has occurred at Mt Hakone near Tokyo starting Monday night through Tuesday, according to officials.

Fresh layers of volcanic ash were discovered Tuesday morning around a newly-formed vent in the Owakudani valley, which forms part of the Mount Hakone range (Fuji-Hakone-Izu National Park) located in Kanagawa prefecture.

Volcanic tremors have been shaking the Hakone mountain since Monday morning, officials said, warning nearby residents that the volcano could eject sizable rocks to a radius of about one kilometer and smaller rocks even further.

The warning level on the Hakone was  raised to level 3 [“Do not approach the volcano,”] at 12:30 JST today [June 30,  2015.]

The volcano has been ejecting steam over the past few months.

Mt Hakone is located about 80 km SW of central Tokyo. More than 45 million people live within a 100-km radius of the volcano according to FIRE-EARTH Population Models.

Explosions at Two Indonesian Volcanoes Force Mass Evacuations

Posted by feww on June 7, 2015

UPDATED

Mt Sinabung and Mt Karangetang erupt, forcing thousands of evacuations

The volume of lava in Mt. Sinabung’s crater has increased to more than 3 million cubic meters and the volcano is in unstable condition, reported PVMBG.

Up to 3,000 residents living within a 7-km radius of Mt. Sinabung, to the south and southeast of the volcano, have been evacuated according to the Volcanology and Geological Disaster Mitigation Center (PVMBG).

Mt. Sinabung’s alert level was raised to the highest level “AWAS,” last week.

The volcano has been ejecting large plumes of volcanic matter since last week, and observers have reported pyroclastic flows cascading down the sides of the mountain.

The 2,460-m high volcano, created by the subduction of the Indo-Australian Plate under the Eurasian Plate, is located in the Karo plateau of Karo Regency, North Sumatra, about 40km from the Lake Toba supervolcano.

Sinabung has four volcanic craters, but only one of them is active currently.


Approximate location of Sinabung is marked  on the map by FEWW. Mount Sinabung is one of Indonesia’s 130  active volcanoes

Meantime, activity continues at Mt. Karangetang, which is located in the district of Sitaro, North Sulawesi, forcing the evacuation of 339 people (106 families).

The “twin-peaked” Mt Karangetang (“Api Siau”), also one of the most active volcanoes in Indonesia, is located on the north side of Siau Island [pop: 43,000] North Sulawesi, in the Celebes Sea.

About 200 million Indonesians, or more than thee-quarters of the population, live within 100-km radius of one or more volcanoes that have become restive at least once during the past 100 years, according to researchers.

Kilauea Lava Flow:  June 27th lava flow continues to advance NE at 120 m/day

The lava flow out of the continuously erupting Kilauea Volcano is slowly advancing downslope toward the town of Pāhoa (population: ~1,000) on the Big Island.

About 4,500 people could be affected by the lava flow in the coming days.

Tuesday Oct0ber 7, 2014 (UTC). Civil Defense Message: “This morning’s assessment shows that the flow front continues to be active and has advanced approximately 150 yards since yesterday.  The narrow flow front is moving along the tree line and the burning activity is producing a significant amount of smoke.  There is no brush fire threat at this time and the burning is limited to the edges of the flow only.  Due to a light southwest wind this morning the vog and smoke conditions were moderate to heavy across lower Puna to Hilo.”

[Note: Vog, a type of air pollution, is formed when sulfur dioxide and other gases and particles emitted by an erupting volcano react with oxygen and air moisture in the sunlight.]

Flow front continues advancing northeast, triggers brush fire. The June 27th lava flow remains active, and the flow front continues to advance towards the northeast along the forest boundary. Today, the flow front consisted of a narrow lobe moving through thick forest. The flow front was 1.7 km (1.1 miles) upslope of Apaʻa St., and 2.7 km (1.7 miles) from Pāhoa Village Road. The lava flow also triggered a brush fire that was active north of the flow front Monday afternoon local time [HAST= UTC -10 hrs.]

Kilauea Status Reports

Issued: Monday, October 6, 2014, 6:42 PM HST (Tuesday, 2014/10/07/04:42UTC)
Source: Hawaiian Volcano Observatory (HVO)
Notice Number: 2014/H13
Location: N 19 deg 25 min, W 155 deg 17 min
Elevation: 4091 ft (1,247 m)
Area: HI Hawaii and Pacific Ocean
Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE

Volcanic Activity Summary: The June 27th flow remains active, with a narrow flow about 115 m (230 ft) wide moving downslope about 120 m/day (390 ft/day) since October 3.

At the average rate of advancement of 120 m/day, the lava could reach Apa`a St. in about 16 days. The advance rate of the June 27th flow has varied significantly during the past month, meaning this projection is subject to change. HVO’s next overflight is scheduled for Wednesday, October 8.

Recent Observations by HVO: The lava flow has continued to advance northeast since October 3 at about 120 m/day (390 ft/day). The leading edge is now about 1.7 km (1.1 mi) straight-line distance from Apa`a St.

Hazard Analysis by HVO: The lava flow from the Pu‘u ‘Ō‘ō vent is active, and lava is being supplied to the flow front, which is slowly advancing downslope toward Pāhoa town, which is located  in the Puna District of the County of Hawai`i.

Puʻu ʻŌʻō Observations: There was little net change in ground tilt at Pu’u O’o over the past day. Glow was visible overnight above several outgassing openings in the crater floor. The most recent sulfur-dioxide emission-rate measurement for the East Rift Zone was 550 tonnes per day (from all sources) on September 25, 2014. Seismic tremor is low and constant.

Summit Observations: Deflationary tilt at Kīlauea’s summit continues this morning along with a decrease in the lava lake level at the summit vent. There was no major change in seismicity on Kilauea over the past day; seismic tremor at the summit remained low and varied with changes in spattering on the surface of the lava lake. GPS receivers spanning the summit caldera recorded about 5 cm (2 in) of extension between early May and early July. Since then, little significant extension or contraction has occurred. During the week ending on September 30, 2014, the elevated summit sulfur-dioxide emission rate was measured at 3,600–5,200 tonnes/day (see caveat below), and a small amount of particulate material was carried aloft by the plume.

Remarks [Source: HVO] : The Pu‘u ‘Ō‘ō vent in the East Rift Zone of Kīlauea Volcano began erupting on January 3, 1983, and has continued erupting for more than 31 years, with the majority of lava flows advancing to the south. Over the past two years, lava flows have issued from the vent toward the northeast. The June 27th flow is the most recent of these flows and the first to threaten a residential area since 2010-2011. On June 27, 2014, new vents opened on the northeast flank of the Pu‘u ‘Ō‘ō cone and fed a narrow lava flow to the east-northeast. On August 18, the flow entered a ground crack, traveled underground for several days, then resurfaced to form a small lava pad. This sequence was repeated three more times over the following days with lava entering and filling other cracks before reappearing at the surface, in two of the cases farther downslope. Lava emerged from the last crack on September 6, forming a surface flow that initially moved to the north, then to the northeast, at a rate of 400 m/day (1,300 ft/day). The flow slowed thereafter and, between September 12 and 19, the rate of advancement varied, averaging 225 m/day (740 ft/day). The flow front stalled by September 22, but new breakouts behind the flow front began to push forward, overtaking the stalled front on September 29 and advancing 120 m/day (390 ft) between October 3 and 6.

Mayon in high state of unrest, explosive eruption possible

Thousands of people have been evacuated from around the foot Mt Mayon, Philippines’ most active volcano, as the crater glow became observable indicating presence of molten lava and superheated volcanic gases.

PHIVOLCS released the following bulletins earlier:

MAYON VOLCANO BULLETIN 16 September 2014 8:00 A.M.

Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network recorded thirty-two (32) volcanic earthquakes and seventy-two (72) rock fall events during the past 24-hour observation period. Intensity III (bright) crater glow was visible last night, although rain clouds prevented visual observation of the crater during the day. Rolling incandescent rockfall within the uppermost reaches of the Bonga Gully last night indicates that the summit lava dome is breaching the crater in its southeastern side. Sulfur dioxide (SO2) flux was measured at an average of 611 tonnes/day on 02 September 2014. Ground deformation data showed inflationary changes in the edifice from February 2014 based on precise leveling surveys on the 3rd week of August 2014, and edifice inflation from January 2012 baselines based on continuous tilt measurement. All the above data indicate that the volcano is exhibiting relatively high unrest due to the movement of potentially eruptible magma.

Mayon Volcano’s alert status has been raised to Alert Level 3.   This means that magma is at the crater and that hazardous eruption is possible within weeks. It is recommended that the 6-km radius Permanent Danger Zone (PDZ) around the volcano and the 7-km Extended Danger Zone (EDZ) on the southeastern flank be enforced due to the danger of rock falls, landslides and sudden explosions or dome collapse that may generate hazardous volcanic flows.  PHIVOLCS maintains close monitoring of Mayon Volcano and any new development will be communicated to all concerned stakeholders.

NOTICE OF INCREASE TO ALERT LEVEL 3:

In the past several hours, a noticeable escalation of unrest was recorded by the Mayon Volcano monitoring network. Since 5:00 AM to 8:00 PM today, 39 rockfall events that are ascribed to incipient breaching of the growing summit lava dome across the southeastern crater rim, and 32 low frequency volcanic earthquakes that indicate magma intrusion and/or volcanic gas activity, have been detected. Crater glow has become observable, indicating incandescence of the crater from molten lava and hot volcanic gas.

In view thereof, PHIVOLCS-DOST is now raising the alert status of Mayon Volcano from Alert Level 2 to Alert Level 3. This means that Mayon is exhibiting relatively high unrest and that magma is at the crater and that hazardous eruption is possible within weeks.  It is therefore recommended that the 6-km radius Permanent Danger Zone (PDZ) around the volcano and the 7-km Extended Danger Zone (EDZ) on the southeastern flank be enforced due to the danger of rockfalls, landslides and sudden explosions or dome collapse that may generate hazardous volcanic flows. PHIVOLCS maintains close monitoring of Mayon Volcano and any new development will be communicated to all concerned stakeholders.

Significant Earthquakes

Iceland has been rattled by 7 significant quakes measuring between magnitudes 4.6 and 5.3Mw since September 10.

  • The largest quake measured 5.3Mw, which occurred 108km WNW of Hofn at depth of 10.0 km on 2014-09-15 at 08:05:02 UTC.

Sweden registered a rare earthquake measuring 4.7Mw, which struck about 59km (37mi) N of Mora, said USGS/EHP.

  • The quake occurred at a depth of about 14.3km (8.9mi), at 13:08UTC on September 15, 2014.

Oklahomans were rattled by at least 4 earthquakes over the last 24 hours. The quakes measured between magnitudes 2.7 and 4.0Mw.

  • The largest quake measuring 4.0Mw occurred about 6km S of Guthrie, Oklahoma at a depth of 4.4 km on September 15 at 20:08UTC.

Japan recorded a magnitude 5.6 shock striking Ibaraki Prefecture about 44km (27mi) NNE of Tokyo, which scared the living daylight out of millions of local kamikazes.

  • The quake registered 5- (Five Minus) on the local 7-point seismic scale.

New fissure eruption near Bardarbunga prompts ‘Red Alert’

Iceland has once again raised its aviation warning to the highest level after a new fissure eruption in Holuhraun lava field near Bardarbunga volcano.

Volcanologists monitoring restive Bardarbunga observed a fissure eruption at 05:15GMT on Sunday, said IMO.

“It appears that the eruptive fissure is longer than in the last eruption. It is extending north and south on the same . The eruption is a very calm lava eruption and can hardly be seen on seismometers. Visual observation confirm it is calm, but continuous.”

Currently, only lava is erupting, but no ash has been observed, added IMO.

The eruption prompted IMO to raise the aviation warning code to ‘red’ for the large area that houses the Bardarbunga volcanic system.

The new fissure is located very close to the Friday’s, with the fracture extending further to the north, said a researcher.

The latest eruption is said to be far more more intense than Friday’s, with the lava flow estimated to be more than 10 times greater.

Meantime, seismicity continues on a 15-km-long region of the dyke intrusion, said IMO, “extending both into the Dyngjujökull glacier and the region north of the ice margin. Earthquakes have not migrated northwards during the last two days.”

An estimated 500 million cubic meters of lava has flowed from beneath the volcano in a long dyke since last week.

Sakurajima’s eruption on Sunday was the most powerful one at the volcano so far this year.

The explosion ejected a column of ash and smoke to a height of about 4.5km above the Minamidake crater, according to local reports.

One of the most active volcanoes in the world, Sakurajima is located in Kagoshima Bay, southern Kyushu, Japan (about 1,100km WSW of Tokyo). The composite volcano has three peaks: Kitadake, Nakadake and Minamidake (southern peak).

Since 1955 the Minamidake crater has been continually active. The ongoing activity includes strong strombolian to ash explosions at least once and as many as 8 times a day.

The volcano was placed under a Level 3 (orange) alert by the Japan Meteorological Agency on March 21, 2012.

Level 3 (orange) alert means the volcano is active (do not approach crater).

A major lava flow in 1914 connected the volcano island  to the Osumi Peninsula on the Kyushu Island.

There were no immediate report of damage or casualties, as of posting.

Some 22,000 people living near Sinabung volcano have been evacuated Since Monday after the volcano erupted in North Sumatra, Indonesia.

The volcano is spewing columns of ash and smoke up to 4.5km above the summit crater, authorities said.

“The National Disaster Mitigation Agency (BNPB) has instructed all relevant ministries, government institutions, local disaster mitigation agencies and the Karo regency administration in North Sumatra to prepare for a worst-case scenario following an increase in Mount Sinabung’s volcanic activity during the past week,” said a report.

The “worst-case scenario” comes into if the exclusion zone is extended from its latest 7km radius, southeast slope of the volcano, to between 7.5 and 10 km from the crater.

More than 60 pyroclastic flows extending up to 5 km from the crater have been recorded with the flow volume increasing every day, said The National Disaster Mitigation Agency (BNPB).

The volume of volcanic material ejected so far is about a quarter of the total 2,540,000 cubic meters formed in Mt. Sinabung’s crater. “This means that the pyroclastic potential stored in the volcano’s lava dome is still substantial; so if it should all come out, the threat would be devastating,” Jakarta post quoted an official as saying.

Chaparrastique Eruption Forces Mass Evacuations in El Salvador

Posted by feww on December 30, 2013

Chaparrastique volcano eruption prompts evacuation of hundreds of communities

Civil protection authorities in El Salvador have imposed a 5-km exclusion zone around the San Miguel volcano, aka Chaparrastique, and are evacuating up to 5,000 villagers that live near the volcano.

The 2,130-m high volcano,  El Salvador’s third highest, ejected columns of smoke and ash up to 5km above the summit.

Chaparrastique, located about  15km SW of San Miguel city (population: 180,000), showed signs of increased activity on December 13.

The eruption has so far deposited more than 10cm of ash in the nearby areas within the coffee-producing region, officials said.

Mass Evacuation Ordered as Mt SINABUNG Put on Red Alert

Posted by feww on November 24, 2013

18,000 people evacuated as Sinabung activity intensifies

Mt Sinabung’s latest explosive eruption has prompted the authorities to raise the volcanic alert to the highest level, “siaga,” or “red alert,” according to Volcanology and Geological Disaster Mitigation Center.

The alert level was raised from “orange” or “level III ” to the highest level “red” or “level IV” by PVMBG on Sunday, as the authorities evacuated an additional  11,618 residents from 19 villages and expanded the evacuation zone to a 5-km exclusion  zone from 3 km previously.

“This is Sinabung’s highest level of activity. The intensity of the eruptions continues to increase,” said Hendrasto, head of PVMBG.

As of 2 p.m. local time on Sunday, Sinabung was continuing to eject an 8-km high column of smoke and ash into the air, he said.

Some 6,000 villagers had already been evacuated from the 3-km exclusion zone, about 90 km from Medan, capital of North Sumatra province.

The North Sumatra health has distributed 180,000 face masks, medicine and 4 tons of baby formula to relief posts in Karo regency, reported Jakarta Post.

Volcano Erupts in Ogasawara Islands

Posted by feww on November 21, 2013

Warning issued to Pacific shipping after volcano erupts, forming a new Island

Authorities have warned shipping in the Pacific Ocean to maintain vigilance for airborne volcanic material after a volcano erupted near one of the Ogasawara Islands, some 1,000 kilometers south of Tokyo, NHK reported Japan’s Meteorological Agency (JMA) as saying.

Japan Coast Guard has confirmed black smoke spewing out of a new land mass about 500 meters southeast of Nishinoshima island, JMA said

Video footage shows a plume of black and white smoke and steam  rising to a height of more than 600 meters above a new landmass measuring about 200 meters across.

“The agency says multiple clusters of white smoke overhead suggest intermittent explosions,” said the report.

Volcanic activity created a new island which was fused to the uninhabited Nishinoshima between 1973 and 1974, the last time when eruptions occurred near the island.

In 2010, one of the volcanoes in the region erupted, spewing smoke and ash to a height of about about 100 meters above the sea level. The surrounding sea area changed to a greenish-yellow color with nearby areas turning cloudy.

JMA said the volcano, called Fukutokuokanoba, had erupted seven times since 1904, forming ephemeral islands (temporary land masses) on three occasions, all of which later sank below the ocean surface.

The first known ephemeral island called Shin-Iwo-jima (New Sulfur Island) was formed in 1904, and the most recent in 1986.

Red Alert at Copahue Volcano: Argentina and Chile Order Evacuation

Posted by feww on May 28, 2013

Chile and Argentina order evacuation of 3,000 people living near Copahue

Argentine and Chilean authorities have issued a red alert, fearing that the volcano could erupt imminently.

The mandatory evacuation order covers all residents living within a 25-km radius of Copahue.

The 2,965m tall volcano began spewing volcanic gasses Friday amid heightened seismic activity, with volcanic tremors occurring at an average rate of about 450 per hour.

Copahue volcano sits in the Biobio region of Chile, straddling the border with Argentina’s Neuquen province.

Second Alaska Volcano Erupts

Posted by feww on May 16, 2013

Pavlof ejects ash and steam, as lava flows down its NW flank

Pavlof Volcano, the second Volcano in the Aleutians to become active, began erupting on Monday and was still spewing clouds of ash and steam on Wednesday, the Alaska Volcano Observatory (AVO) said.

The volcano has been emitting intermittent dark clouds of ash and steam rising up to 20,000 feet a.s.l. and drifting in a northeasterly direction, the observatory said.

  • Mt Cleveland, the other currently active Alaskan volcano, has been erupting intermittently since 2011.
  • Volcanic ash from Pavlof and other Alaska volcanoes could pose a threat to air traffic in the region.

55°25’2″ N 161°53’37” W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

The eruption of Pavlof Volcano continues. Elevated seismic activity persists and a steam and ash cloud are visible in web camera images rising occasionally up to about 20,000 ft. above sea level. A diffuse ash plume was reported late last night at an altitude of 15,000 above sea level and extending downwind to the northeast for up to 100 miles before dissipating. A recent pilot report today indicated a dark ash cloud extending east-northeast at an altitude of 20,000 above sea level. National Weather Service issued a Sigmet yesterday that remains active today.

Residents of Cold Bay, located 37 miles southwest of the volcano, observed incandescent glow at the summit during the night. Pilot reports and photographs from yesterday afternoon indicate that the lava flow extending down the northwest flank is still active and has generated debris-laden flow deposits, presumably from interaction of hot lava with the snow and ice on the flank.

CLEVELAND VOLCANO (CAVW #1101-24-)

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Elevated surface temperatures continued at Cleveland Volcano over the past 24 hours. No explosions have been detected by regional infrasound data. There has been no further information about the lava flow.

Sudden explosions of blocks and ash are possible with little or no warning. Ash clouds, if produced, could exceed 20,000 feet above sea level. If a large ash-producing event occurs, nearby seismic, infrasound, or volcanic lightning networks should alert AVO staff quickly. However, for some events, a delay of several hours is possible. Cleveland Volcano does not have a local seismic network and is monitored using only distant seismic and infrasound instruments and satellite data.

AVO will continue to monitor these volcanoes and issue additional information as available.

Code Definitions
ORANGE Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible].

WATCH: Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway but poses limited hazards.

‘Red’ Alert at Copahue Volcano

Posted by feww on December 24, 2012

Copahue volcano activity could intensify

Authorities in Argentina and Chile have raised the alert at Copahue volcano  in Biobio region to the highest level after detecting continued seismic activity on Sunday.

  • Copahue first erupted on Saturday, showering ash on nearby villages and prompting many to evacuate.
  • “The intensity of seismic signals suggests the eruption in progress is on the smaller side [however] we cannot discount the possibility that the activity could turn into a larger eruption,” said a spokesman for the Chilean Geology and Mining Services.
  • The 2,970-meter volcano is in SW Argentina’s Neuquen province, near the Chilean border.
  • About 3,000 people live in the vicinity of the massive volcano, including  the residents of Copahue, the town of Caviahue and indigenous Mapuche communities.
  • The ash plume rose  to a height of about 1.5km (5,000ft) above the crater, said Chile’s emergency office (ONEMI).

Beerenberg Volcano Could Explode

Posted by feww on May 25, 2012

FIRE-EARTH FORECAST: Beerenberg Volcano on Jan Mayen Island Could Erupt Explosively [P≥ 64%]

The 2,280-m stratovolcano located on Jan Mayen Island could erupt this year with a probability of at least 64 percent.

The 6.2Mw earthquake (72.994°N, 5.651°E; 8.8 km; Thursday, May 24, 2012 at 22:47:46 UTC) and its subsequent aftershocks that occurred in the Norwegian Sea may have primed the volcano for an explosive eruption.

Jan Mayen (Norway) is a volcanic island  located in the north Atlantic Ocean, some 950km west of Norway and 600 km north of Iceland. The view of the island is dominated by the active volcano Beerenberg (2,280m), which last erupted in 1985, emitting an estimated total of about 2  x 107 m3 of lava and other volcanic matter.
