 Ubinas Volcano emits ash, smoke: shaken by violent spasm of tremors

February 5, 2014 – PERU – The Ubinas Volcano near the southern city of Arequipa in Peru has become active again after several months of minimal activity. According to El Comercio, the volcano is emitting columns made of ash, smoke, and steam, as well as registering seismic movements. Since Jan. 31, the volcano has reportedly experienced as many as 100 seismic events every day, including a Feb. 1 movement which lasted for seven hours.
El Comercio reports that the various ash columns released by the volcano have reached heights from 700 to 2,000 meters. The volcano’s recent activity has been attributed to water seeping into the crater. When the water comes into contact with magma, the it turns into steam, which then creates pressure inside the crater. This pressure is what causes the volcano to expel ash. No damages have been reported as a result of the volcano’s most recent activity.
A series of similar explosions in September created health problems for many local residents, some of whom suffered from headaches and gastrointestinal problems after breathing the silicon ash released by Ubinas.
The Ubinas Volcano, located in the Moquegua region 70 kilometers outside of Arequipa, has displayed a sudden burst of activity. Prior to the September eruptions, the volcano had been dormant since 2009.

A third of Ecuador’s provinces covered with ash from Tungurahua

February 5, 2014 – ECUADOR – 
A cloud of ash that climbed more than 4 km from the Tungurahua volcano Monday has affected a third of Ecuador’s provinces and forced the suspension of classes at some schools after temporarily closing a regional airport. A series of 10 powerful cannonlike blasts shook the 5,023-meter volcano Sunday night and could be heard for kilometers. Tungurahua is roughly 150 km south of Quito. Fernanda Naranjo of Ecuador’s geophysics institute said there have been no pyroclastic flows — fast-moving, superhot fluidized masses of rock fragments and gases — since Saturday.

New activity at Etna: 
After a short pause with likely no (or almost no) eruptive activity during 1-2 Feb, the volcano started renewed lava effusion from the fissure vent at the eastern foot of the New SE crater yesterday, followed by the onset of weak explosive activity(ash emissions) from the New SE crater this afternoon. So far, this activity has been very weak and the lava flow progressed only a few 100 m. The tremor signal is low and doesn’t show a clear trend at the moment.

6.1 magnitude earthquake strikes Indonesia

Indonesia 6.1 Feb 4
February 4, 2014 – INDONESIA – The U.S. Geological Survey says a magnitude-6.1 earthquake has been recorded in Indonesia. The Pacific Tsunami Warning Center has no warning in effect. The Geological Survey report says the quake hit 197 miles (318 kilometers) east of Dili, East Timor, just after 1730 GMT. The quake’s depth was recorded at 11 miles (18 kilometers). Indonesia is located on the Pacific “Ring of Fire,” an arc of volcanoes and fault lines encircling the Pacific Basin. –ABC News
February 2014 – INDONESIA The government has raised the status on another 19 volcanoes in the country to alert level — the second-highest category — in the wake of the Mount Sinabung eruption in North Sumatra that killed 16 people on Saturday. Besides the 19 new additions, three volcanos have been on high alert status since last year. They include Lokon and Karangetang in North Sulawesi and Rokatenda in East Nusa Tenggara. The National Disaster Mitigation Agency (BNPB) issued the raised status on Monday for the 19 volcanoes, which are scattered across the archipelago, but has yet to call for the evacuation of populations living nearby. The 19 volcanoes are Kelud, Ijen, Bromo, Semeru and Raung in East Java; Lewotobi Perempuan in East Nusa Tenggara; Ibu, Gamkonora, Dukono and Gamalama in North Maluku; Soputan in North Sulawesi; Sangeang Api in West Nusa Tenggara; Papandayan in West Java; Dieng in Central Java; Seulewah Agam in Aceh; Talang and Marapi in West Sumatra; Anak Krakatau in Banten; and Kerinci in Jambi. Indonesia is among the world’s most seismically active countries, situated on the Pacific Ring of Fire, an arc of volcanoes and fault lines encircling the Pacific Basin. The 19 volcanoes are among about 127 active volcanoes in Indonesia. Mt. Sinabung has been sporadically erupting since September. Though the alert level for the 19 volcanoes had been raised, Sutopo called on nearby residents not to panic. “Volcanoes erupt in stages, they won’t suddenly erupt. Their activity can be categorized from normal to waspada [alert] to siaga [high alert] to awas [danger, the highest level],” he said on Monday.
He said that the BNPB was now keeping an eye on Mount Kelud, whose status was raised to alert following intensified volcanic activity. The BNPB decision to raise the status of Mt. Kelud had triggered panic among local residents. Local officials in Kediri have issued a warning to people living close to Mt. Kelud to stay outside a 2-kilometer radius set by the The Center for Volcanology and Geological Disaster Mitigation (PVMBG). On Saturday, at least 16 people were killed and three others severely injured due to pyroclastic clouds emitted by Mt. Sinabung. Previously, the volcano’s ongoing eruptions had claimed the lives of 31 evacuees from various illnesses such as depression, asthma and hypertension. Rescuers had to halt operations due to fears of further eruptions. Currently, the evacuation zone is between 5 and 7 km on the southeast slope of the volcano. Sixteen villages had to be evacuated following the eruptions. Meanwhile, responding to the BNPB report, Coordinating Minister for People’s Welfare Agung Laksono called on people living close to the volcanoes to remain calm. “[The raising of the alert status] is to raise awareness among government officials and members of the public so that they can anticipate the worst from the early stage,” Agung said as quoted by Antara news agency. Agung said that the population in a disaster zone should heed government instructions to evacuate in the event of a volcanic eruption. “We ask for cooperation from residents. If the local government decides to evacuate their neighborhood they have to follow the procedures,”
 Agung said. The country has been battered by a string of natural disasters in recent months. Authorities in a number of disaster-prone regions have been warned about the potential for worsening disasters, including landslides and floods, due to heavy rains nationwide. In West Java, the PVMBG advised that people living in landslide-prone areas in Ciramba and Mekarmulya subdistricts, Cikalong district, Cianjur, should be relocated. In Jombang, East Java, 14 people were buried by a landslide on Monday. Seven bodies have been recovered, while the other seven remain missing. In Semarang, a landslide displaced 32 families from the Tangkil Baru residential complex in Sukorejo subdistrict, Gunungpati district, whose houses were destroyed. Last week, sections of the Java’s northern coastal highway were inundated by floodwaters causing a major traffic disruption. In East Java, the flooding disrupted traffic from Situbondo to Surabaya.

Alert level raised on Indonesia’s Kelut volcano in East Java, following seismic swarm

 

Volcanic unrest ripples across Indonesia: A lava dome emerged from the crater lake of Kelut following an eruption in 2007
February 3, 2014 – INDONESIA – The alert level of the volcano was raised today on Kelut or Kelud volcano from 1 (‘normal’) to 2 (“Waspada,” or ‘watch’) on a scale of 1-4. During the second half of 2014, a strong increase in seismic activity and a 5.5 deg temperature increase of the crater lake water had been detected. The number of shallow volcanic earthquakes rose from averages of 1-2 per day to approx 10 per day during 20-31 Jan and climbed to more than 100 events since the start of February alone.
This might indicate a shallow intrusion is taking place and could lead to a new eruption. VSI had recommended a 2 km radius exclusion zone from the crater. The last eruption of Kelut was in Oct-Nov 2007, when a new lava dome grew within the crater lake. –Volcano Discovery
