At least a dozen people were killed or seriously injured after Sinabung erupted on Saturday, ejecting large clouds of smoke and ash about 3km into the air, as an avalanche of superheated pyroclastic flows descended down the mountain inundating the village of Gamber.
The victims are thought to be local villagers farming within the 4-kilomere exclusion zone when they were consumed by pyroclastic clouds.

“People and visitors/tourists are not allowed to conduct any activity within a radius of three kilometers from the mountains top. People living in the south and southeast sector are also prohibited to get as near as seven kilometers from the mountains top while those in north and northeast sectors are prohibited to get as near as four kilometers from the mountains top,” said an official at the National Disaster Mitigation Agency (BNPB), Sutopo Purwo Nugroho.
About 60,000 people have been displaced since Sinabung volcano awoke in 2013 after a period of dormancy.
Indonesia has 129 active volcanoes, of which at least 79 have erupted since the 1600s. Some 66 volcanoes are continuously monitored from 76 observatories.

Malaysian schools have been ordered closed as a hazardous smog from Indonesian forest fires blankets the capital, multiple states and neighboring Singapore.
At least 34 of Malaysia’s 52 air quality stations were recoding unhealthy air levels on Tuesday, according to local reports.
Meanwhile, Indonesian authorities declared a State of Emergency in Sumatra’s Riau province as hazardous levels of pollution were reported in multiple regions, including Sumatra and Borneo.
“Tens of thousands of people in smoke-choked regions of Sumatra and Borneo have fallen ill, while air travel there has also been disrupted due to poor visibility,” said a report.

All 113 people on board an Indonesian military transport plane that crashed Tuesday in a major city on the Indonesian island of Sumatra are believed to have been killed, according to the country’s air force chief.
The Hercules C-130 crashed into two houses and a hotel before bursting into flames in a residential area of Medan city [metro pop: ~ 5 million,] according to the chief.
The number of casualties on the ground has not yet been established.
Medan is the capital of the North Sumatra province, and is the fourth largest city in Indonesia.
Mandala Airlines Flight 091
On 5 September 2005, Mandala Airlines Flight 091 crashed into a populated area of Medan shortly after take-off from the city’s airport, killing 149, including 49 people on the ground. Additionally, some of the 17 people on board the plane who survived the crash, and 26 others on the ground who were injured, are believed to have since died as a result of their injuries.

“We pledge that every consumer will receive water, but it will be rationed to ensure supply every two days,” the state chief minister was reported as saying.
“In a week, consumers will receive water for four days.”
Meanwhile, authorities revealed more than 7,000 forest and bushfires had been reported throughout the country since early February, five times the normal.
The state of Negeri Sembilan, near the Malaysian capital of Kuala Lumpur, has already declared a “state of crisis” due to water shortage.
“In peninsular Malaysia, 15 areas have not had rainfall in more than 20 days, with some of them dry for more than a month, according to the Malaysian Meteorological Department. The dry weather is expected to run for another two weeks,” reported Reuters.

The city-state of Singapore has experienced its longest dry spell on record, between January 13 and February 8, and has received little rain since.
Authorities say the dry weather contributed to the death of fish stocks at offshore aquaculture facilities. More than 160 tons of fish have perished recently due to a lack of oxygen in the water.
Governor of Riau declared a province-wide state of emergency as forest-clearing fires raged out of control due to drought.
Smog caused by record air pollution has enveloped a large region of Sumatra, forcing the pollutants standard index (PSI) to climb to a hazardous 778, and prompting authorities to close schools and urge residents to stay at home.

Satellite images showed more than 700 hotspots in Sumatra alone on February 15, nearly twice the number the previous day, with at least 600 of the blazes in Riau Province , said a report.
“We have asked the central government to help with fighting fires by sending aircraft,” said the newly-sworn-in governor of Riau.
“If it’s just helicopters, we won’t be able to cope.”

Mt Sinabung Erupted three times on Saturday leaving at least 14 people dead, including a group of school children from Medan on a science trip, and three others critically injured. Authorities were again forced to evacuate tens of thousands of people from 16 villages from the 5km – 7km exclusion zone near the volcano.
“This is the first direct impact of the Mt. Sinabung eruptions. Before the Saturday incident, the ongoing eruptions have already claimed the lives of 31 evacuees, as a result of various illnesses such as breathing difficulties, depression, asthma and hypertension.” Jakarta Post reported.
Some 14,000 of more than 30,000 evacuees had just been allowed to return home on Friday, following earlier eruptions.

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.
About 22,000 people have been evacuated near Mt Sinabung as the volcano continues to erupt. Mount Sinabung has been ejecting columns of ash and smoke up to 4.5km above the summit crater since Saturday. More than 60 pyroclastic flows extending up to 5 km from the crater have also been recorded. Photo credit: Agung Kuncahya B./Xinhua. More images…
“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.

FEWW Comments: The strong earthquake may have primed for eruption either one or both of two volcanoes Bárcena, which forms the island of San Benedicto, and Socorro, located on island of the same name, about 380 km to the west of the EQ location.
Bárcena volcano forms the elongated island of San Benedicto, seen here from the SW in March 1955. The tuff cone with the circular summit crater at the center and the lava delta to the right were formed during an eruption in 1952-53, the only eruption known from this volcano in historical time. Pleistocene trachytic lava domes are located at the far NE tip of the island. Dark-colored lava domes from the 1952-53 eruption can be seen in the summit crater. Photo by Adrian Richards, 1955. Caption: GVP
Cerro Evermann, the high point of Socorro Island, rises above a Mexican Naval camp near the southern tip of the island. Socorro lies in the Revillagigedo Islands south of Baja California. Cerro Evermann is a large tephra cone and lava dome complex that forms the 1050-m-high summit of the volcano. Rhyolitic lava domes have been constructed along flank rifts, and silicic lava flows erupted from summit and flank vents have created an extremely irregular shoreline. Only minor explosive activity has occurred in historical time. Photo by Martha Marin, 1998 (Mexican Navy). Caption: GVP
Bárcena and Socorro are shown to the lower left of the map.

The Indonesian volcano Talang on the island of Sumatra had been dormant for centuries when, in April 2005, it suddenly rumbled to life. A plume of smoke rose 1000 meters high and nearby villages were covered in ash. Fearing a major eruption, local authorities began evacuating 40,000 people. Caption: James A. Phillips, NASA.
And just to confuse the readers a little, the following caption is by volcano.oregonstate.edu
Talang is a stratovolcano with 8 confirmed eruptions between 1833 and 1968. The volcano may have had a phreatic eruption in 1986 but the activity has not been confirmed. Most of the eruptions are moderate in size (VEI=2) and explosive. Eruptions in 1833, 1843, 1845, and 1876 were from flank vents. An eruption in 1967 and two different eruptions in 1968 were from radial fissures. The distance from the city of Padang to Talang is about 35 km. Image courtesy of the Landsat Pathfinder Project.
TALANG
Country: Indonesia
Region: Sumatra
Last Known Eruption: 2007
Summit Elevation: 2,597 m (8,520 feet)
Latitude: 0.978°S (0°58’42″S)
Longitude: 100.679°E (100°40’46″E)
Source: GVP
Talang, which forms a twin volcano with the extinct Pasar Arbaa volcano, lies ESE of the major city of Padang and rises NW of Dibawah Lake. Talang has two crater lakes on its flanks; the largest of these is 1 x 2 km wide Danau Talang. Most historical eruptions have not occurred from the summit of the volcano, which lacks a crater. Historical eruptions from Gunung Talang volcano have mostly involved small-to-moderate explosive activity first documented in the 19th century that originated from a series of small craters in a valley on the upper NE flank.

Authorities raise Mt. Talang alert level to highest
The vulcanology and disaster mitigation office in West Sumatra has raised the alert status for Mt. Talang to the highest level following a 6.9-magnitude earthquake and a series of aftershocks that struck the province.
Vulcanologist Dalipa Marjusi said Tuesday the tremors had sparked a volcanic earthquake and temblors, although eruption of the volcano remained undetected.
“Since Sunday’s earthquake we have recorded 1,600 volcanic quakes and 700 tectonic quakes, but only 23 of them were felt,” Dalipa said.
Fog has blanketed the summit of the 2,597-meter volcano for the last two days, making it difficult to see ash or lava that might be erupting from its crater.
The volcano last spewed hot ash last April.
A seven-strong team from the directorate general of vulcanology and disaster mitigation have arrived in Padang from Bandung to monitor the volcano’s activities.

Notes:
IG reported that on 4 August seismicity from Reventador increased and periods of tremor frequently saturated the seismic stations. On 6 August, incandescent blocks were ejected from the crater. Thermal images revealed a linear area of higher temperatures, confirming the presence of a new lava flow on the S flank.
Based on analyses of satellite imagery, the Washington VAAC reported that on 14 August a 2-hour-long thermal anomaly detected over Pagan was followed by a small emission. The emission, hotter than its surroundings, drifted NW and quickly dissipated. [Source: GVP]

The powerful earthquake, originally reported as measuring 7.0Mw, struck in the Kepulauan Mentawai Region, Indonesia, about 110 km WSW of Padang, Sumatra, Indonesia, at a depth of 44.8km on Sunday August 16, 2009, USGS reported.
The earthquake, which was later downgraded by USGS EQ Hazard Program was followed by a cluster of aftershocks at the time of writing, the largest of which measured 5.9Mw.
[ Note: FEWW Moderators have noted that at least a dozen or so earthquakes which were initially reported as measuring 6.0 or greater, have been subsequently downgraded by USGS without any explanation. Moderators also noted an earthquake reported in Alaska, which measured greater than 5.0, was withdrawn from the USGS report last week, again without any explanation.]

Mount Kerinci, the highest mountain in Sumatra, is undergoing a period of unrest, punctuated by at least three explosive eruption, spewing smoke and ash into the air.
The local volcano observation monitor also reported repeated tremors at the base of the volcano.
Two explosive eruptions were reported Sunday and Monday, spewing smoke and ash to a height of about 400m with ash covering the tea plantations on the mountain slope and posing a threat to the populated areas below.
Another, less powerful, explosion reportedly occurred earlier today.
The head of Mount Kerinci Observation Post was reported as saying that Kerinci volcano has been showing signs of unrest in the past week.
“We have warned local people to remain cautious. We told them it’s better to wear mask when going outdoor,” he said.
One of the most active volcanoes in Indonesia, the 3,800-meter high Mt. Kerinci, a stratovolcano, sits on the border of Jambi and West Sumatra .

The unvegetated summit of 3800-m-high Gunung Kerinci in central Sumatra, Indonesia’s highest volcano, is seen from Pengamatan on its southern flank. Kerinci is one of the most active volcanoes in Sumatra and has been the source of numerous moderate explosive eruptions since its first recorded eruption in 1838. The massive 13 x 25 km wide volcano towers 2400-3300 m above surrounding plains and is elongated in a N-S direction.

FEWW Volcanic Forecast:
1. The Loyalty – New Hebrides Arc Collision. Intense volcanic activity should be expected throughout 2009 and beyond along the New Hebrides arc, the Vanatu region (also to the north to include Solomon Island and Santa Cruz Island), possibly continued along the New Hebrides Trench (to include Matthew and Hunter Island). Volcanoes that are located in the above-described area include:
2. Pacific Plate subduction beneath the Okhotsk Plate. Subduction of the Pacific Plate beneath the Okhotsk Plate continues to create Intense volcanism. Starting 2009, however, a much greaterthan the average number of volcanoes located on the Kuril Islands island arc, Kamchatka volcanic arc and Japan trench to the south may erupt with renewed intensity.

Sibayak volcano in NE Sumatra and its twin volcano Mt. Pinto are constructed within a compound caldera. The slightly higher Mt. Pinto partially overtops the 900-m-wide crater of Sibayak on the north. The summit contains a lava dome and an area of hydrothermal alteration visible in this photo. An ash eruption from Sibayak was recorded in 1881, and area residents note legends of eruptions.
