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.

Fissure eruption reported in Holuhraun lava field, Dyngjujokull glacier, Iceland
The eruption breached surface in Holuhraun lava field about 5km north of Dyngjujokull about 00:02 GMT on Friday, said IMO.
Seismic activity has decreased as a result of the pressure release, however a significant amount of earthquakes is still detected in the magma dike, between the eruption site and south to about 5 km into Dyngjujökull.
The aviation color-code was raised to “red” and back to “orange,” as there was no ash emission.
A significant shock measuring 5.2Mw centered at 64.770°N, 17.335°W occurred at a depth of 7.5km at 12:21UTC, said USGS/EHP.
Tavurvur Volcano Erupts in Papua New Guinea (PNG)
Mount Tavurvur on PNG’s East New Britain Island erupted violently at 3.00 a.m. local time, said Rabaul Volcanological Observatory.
It ejected plumes of smoke and ash to a height of about 17,000m over the South Pacific island country, forcing the authorities to warn local residents to stay indoors, and causing airlines to alter some flight paths.
“Flight paths between Sydney and Narita (Tokyo) and Sydney and Shanghai have been altered as a result of the volcanic ash cloud over Rabaul in eastern Papua New Guinea,” Qantas spokeswoman told Reuters.
The eruption reached the top of the atmosphere at 50,000 feet, which is the same height as which planes travel, could disrupt air flights from Australia, said the Volcanic Ash Advisory Center in Darwin, Australia.
M5.6 Quake Strikes South of Athens, Greece
Centered at 36.738°N, 23.757°E, about 137km south of Athens, the quake struck at a depth of 91.8km, said USGS/EHP.
The quake was felt in Athens; however, there were no reports of casualties or severe damage, as of posting.

Volcanic Activity Continues at Japan’s Sakurajima
Sakurajima’s eruption on Friday was the most powerful one at the volcano since last month when the volcano spewed large columns of ash with rivers of lava flowing in the direction of nearby Ibusiki City.
Ash clouds from Mt. Sakurajima explosion reached a height of 4,500 meters, the second-highest since 1955. A record of 5,000 meters was set in 2013.
Ash fall was reported late Friday evening in areas southeast of the volcano.
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).

Ongoing Eruptions
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.

Mt Merapi eruption follows multiple explosions at Mt Sinabung
“Mount Merapi experienced a phreatic eruption. Its status remains normal due to a lack of activity,” said Yogyakarta’s Geological Disaster Technology Development and Research Agency (BPPTKG).
On November 16, 2013 FIRE-EARTH warned: 22 Indonesian Volcanoes Remain on High Alerts
Mt Merapi was placed on “Yellow Alert,” or “Level II” of the country’s 4-level alert system, on August 3, 2013.

“On Monday at 4:52 a.m. before the eruption, BPPTKG detected an earthquake in Ciamis, West Java, at a magnitude of 4.7 on the Richter scale. The tectonic quake is believed to have shaken the magma chamber of Mount Merapi causing it to release gas from below,” said BPPTKG spokesperson.
Merapi ejected volcanic materials about 2 kilometers into the air showering a 60-km radius area east of the volcano with ash, said the report.
The authorities have since imposed 1-kilometer exclusion zone around the volcano base.
The phreatic eruption on Monday was similar to one on July 22, said National Disaster Mitigation Agency (BNPB) spokesman. “But today’s was more powerful than the July 22 eruption.”
More than 600 families living in Kalitengah Lor, Kalitengah Kidul and Srune hamlets, in Glagaharjo village, Sleman regency, Yogyakarta, have been evacuated.
Hundreds of other villagers living on the western flank of Mount Merapi also fled their homes.
“The volcanic ash also affected residents in nearby towns. In Surakarta, Central Java, residents were shocked by the sight of volcanic ash covering streets, gardens and roofs. The ash rain continued until around 10 a.m. on Monday.” said the report.
“Surowedanan village in Boyolali, located around 17 km from the peak of Mount Merapi, was also covered by volcanic ash. ‘This morning, when I went out of the house at around 5 a.m., I saw ash everywhere,’ said Veronica Maria Sayektiana, of Surowedanan. According to Veronica, residents were wearing masks when they ventured out of their homes as the ash was still falling along with the drizzle.”
Merapi eruptions have killed hundreds of people in the past couple of decades.
Mount Merapi is one of the most active volcanoes in Indonesia. The 2010 its eruptions killed more than 300 people dead and forced about 400,000 people to evacuate their towns, while a 1930 eruption left at least 1,300 dead.
Mt Sinabung Update
The Indonesian ministry of transportation has diverted all flights to avoid routes near Mt Sinabung, located in Karo District, North Sumatra, which has erupted multiple times since last week.
The authorities say Mt Sinabung eruption on November 12 ejected volcanic material that covered five districts destroying some 1,893 hectares of citrus plantations in Tanah Karo, which has impacted fruit production, said a report.
The explosive activity follows a series of most recent eruptions exhibited by the 2,460-meter high volcano that began in September 2013, leading to a significant eruption on October 24, which saw the volcano spewing smoke and ash to a height of about 3km above the crater summit, followed by other eruptions, especially the explosive eruption that occurred on Sunday, November 3.

Ash Cloud Heads Toward UK, Grounds Flights
The towering column of smoke and ash registered a height of about 13km earlier today.
All flights to and from Scotland have been cancelled as a large volcanic ash cloud produced by Grímsvötn in Iceland heads toward the UK.
Airlines including BA, KLM, Aer Lingus, Loganair and Eastern Airways have cancelled flights on Tuesday, and several flights over the Atlantic were reportedly delayed. Hundreds of tourists have been evacuated from Iceland’s national parks.
Fly-til-Your-Planes-Fall-Out-of-Sky
“[There were now] much more robust systems [in place to] minimize the disruptive effect [of volcanic ash clouds,]” the UK transport secretary Philip Hammond told BBC news.
“Most importantly, the basic situation now is that the threshold for most aircraft is 20 times where it was last year. We have got from 200 microgrammes per cubic metre to 4,000 microgrammes per cubic metre as the threshold up to which most aircraft can fly.”

The 1783-84 Deadly Eruption
The Grímsvötn volcanic system erupted from a 130-crater fissure in the Grímsvötn volcanic system called Laki or Lakagígar fissure, and Grímsvötn volcano for 244 days (8 June 1873 to 7 February 1784), spewing at least 15km³ of basaltic lava, world’s largest and deadliest volcanic eruption, causing widespread damage to crops and destroying more than a half of Iceland’s livestock (including 85 percent of the sheep), and leading to a severe famine that resulted in the loss of about quarter of the Icelandic population.
The emission of sulfuric aerosols from Lakagígar eruption is said to have caused a drop in global temperatures, resulting in crop failures in Europe, droughts in India and China, as well as a severe famine in Japan, killing an estimated six million people globally.

Volcanic Ash Affecting Japan’s Air
Shinmoedake Volcano Continues to Erupt on Japan’s Kyushu Island
FIRE-EARTH is advised that volcanic ash from Shinmoedake has traveled to at least as far as the Osaka region, some 500km northeast of the volcano, affecting air “quality.”
A combination of volcanic ash and dust from China has created a haze in the atmosphere, reducing solar power generation in the region by up to 20 percent in the last 48 hours, local sources told the blog.
The 1,421-meter (4,660 feet) volcano in the Kirishima volcanic complex erupted today at about 9:40JST following three eruptions yesterday, ejecting a plume of ash and smoke up to 3,000m into the air, local reports say.
University of Tokyo’s Earthquake Research Institute professor Setsuya Nakada says a much larger eruption is possible.
“Following the first major eruption on Jan. 26, the second and the third eruptions occurred at one to three-day intervals. After the fourth eruption shortly before 8 a.m. on Feb. 1, however, a total of five eruptions, including the latest at around 8 a.m. on Feb. 3, occurred at shorter intervals of five to 15 hours.” Japan’s Mainichi Daily News said.
A lava dome created by the eruption covers the volcano’s crater, which is 700m wide and 200m deep. The dome has reached a height of about 110m above the crater rim, a Geospatial Information Authority of Japan announcement on Feb. 2 said.
Sakurajima Volcano
Japan’s Meteorological Agency (JMA) has raised the alert level to 3 for Sakurajima volcano, located about 45 kilometers (28 miles) to the southwest. The volcano is one of Japan’s most active, accounting for more than 1,000 episodes in 2010, the most activity recorded since 1982, JMA reported.
“Most worrying is the enormous damage that could be caused by volcanic rock spewed out of the mountain, as well as by pyroclastic flows. In fact, a volcanic rock about 50 centimeters in diameter was found about four kilometers from the crater, and in a forest about three kilometers from the crater, there is a hole 5 meters wide and more than 2 meters deep that was created when volcanic rocks struck the spot.” Said a report.

Submarine Volcano Erupts Near Sarigan Island
An underwater volcano off Sarigan Island, Northern Marianas, about 160km (100 miles) north of the island of Saipan erupted on Saturday sending a plume of steam and ash cloud into the air and showering the ocean surface with volcanic debris, US officials reported on Monday.
“An EMO observer aboard an overflight yesterday reported a large area of debris floating in the sea south of the island, and a stationary area of discoloration in the water, presumably above the vent. The crew on Sarigan reported passage of a small wave (less than 0.5 m) following onset of the eruption yesterday.” USGS said.
However, satellite images show no sign of ongoing activity, USGS said.
“Seismicity at a single nearby station on Sarigan Island declined soon after the eruption of a large steam and ash cloud from a submarine vent 11 km (7 miles) south of Sarigan Volcano early yesterday. Satellite images show no sign of ongoing activity.”
Scientists had initially thought the volcanic cloud came from either of the Anatahan or Sarigan volcano, and later verified the source by the trail of debris and water discoloration close to the vent, a USGS official said.
The Northern Mariana Islands are located about 6100km (3,800 miles) southwest of Hawaii.
Summary of Volcano Details (USGS):
- Volcano Location: N 16 deg 42 min E 145 deg 46 min
- Area: Mariana Islands
- Summit Elevation: 1765 ft (538 m)
- Volcanic Activity Summary: Seismicity and subaqueous eruptive activity have declined at Sarigan Volcano prompting reduction of the Aviation Color Code to YELLOW and the Volcanic Activity Level to ADVISORY.

Magma Intrusion – 05 May 2010 13:40
Icelandic Met Office (IMO) has detected increased seismic activity beneath Eyjafjallajökull starting Monday 3 May. “Precise locations of the earthquakes show that their source is at first very deep, at about 23 km depth, but then migrates upwards. This strongly indicates that “new” magma is intruding into the magma conduit and pushing on the over-lying magma, causing a difference in pressure at the surface. It is therefore anticipated that the eruption will continue at full force in the next days.”
Plume Height
IMO’s weather radar reported the plume height reaching to a height of about 6.5km a.s.l.
Lava Flow
Lava is flowing in a northerly direction and spreading at 500 m a.s.l., IMO said. “The lava tongue is about 200 m wide and lava channels that join at the tongue are about 30-60 m wide. The lava channels gets wider every day.”
GPS deformatio
IMO reported significant horizontal movement at GPS stations mounted around
Eyjafjallajökull in the last 2 days.

Santiaguito volcano rains ash over western Guatemala
On 20 April, INSIVUMEH reported explosions from Santa María’s Santiaguito, which produced ash plumes rising to altitudes of 2.8-3.4 km (9,200-11,200 feet), Global Volcanism Program said.
On Monday 26, April the volcano erupted violently sending a plume of ash 8.3 km (27,300 feet) a.s.l., news articles reported.
The volcano has calmed since Monday’s violent burst, however, it’s still erupting, according to disaster response agency spokesman David De Leon, AP said.
De Leon was quoted as saying that the eruption had damaged local flower harvests, though no injury was caused. A no-fly ban was imposed 20 kilometers from the volcano schools were closed in 10 communities as a precaution.
Formed during a catastrophic eruption in 1902, Santiaguito is a 1-km-wide crater on the 3,772-meter Santa Maria volcano, located about 200 kilometers northwest of Guatemala City.
It’s believed that about 2,500 people were perished as a result of the 1902 eruption.

Thar: Another Encroaching Desert
Pall of Dust Covers Pakistan-India Border Region
The nearest volcanoes from the Thar Desert on the Pakistan-India Border Region are about 1,000km away. And there aren’t nearly as many of them as in Iceland. The area won’t receive a significant amount of the volcanic ash from Eyjafjallajökull Eruption, but there would be plenty of sand and dust to compensate for the airborne particles.
