1.2 million to evacuate in Japan’s Mt. Fuji Volcano erupts Tags: Mt. Fuji Volcano erupts

1.2 million to evacuate in Japan’s Mt. Fuji Volcano erupts


February 7, 2014 – JAPAN A new evacuation plan outlined in preparation for a possible Mt. Fuji eruption would displace an estimated 1.2 million people. Two-thirds of the number, or around 750,000 people, come from the prefectures of Shizuoka and Yamanashi, while another 470,000 currently reside in Kanagawa. A UNESCO World Heritage site, 3,776-meter Mt. Fuji is an active volcano that has erupted many times in the past. It is situated between Shizuoka and Yamanashi prefectures, and also near Kanagawa.
A hazard map for the volcano was prepared in 2004 and showed areas which are at high risk of being affected by volcanic ash. Notable areas in the three prefectures are populated with wooden houses, in which locals reside. Should the volcano erupt, these houses are at risk of being crushed under heavy volcanic ash that gets its weight after absorbing rain in the atmosphere. An estimated 406,000 people from Kanagawa, 62,000 in Shizuoka, and 1,000 in Yamanashi would be affected by heavy ash measuring 30 centimeters or more.
A bigger number of around 8.85 million living in other areas of the three prefectures may have their health at risk with at least 2 cm of volcanic ash. While the direct effect of volcanic ash on the population varies on other factors such as wind direction, the Meteorological Agency may still issue a strict warning based on its observations and simulations.
Meanwhile, an evacuation plan for when lava flows shows the area within the volcano divided into five parts, and dependent on the time the lava is expected to reach their towns. The current evacuation plan drawn does not include volcanic eruptions, which may happen after a major earthquake comes from the Nankai Trough in the Pacific Ocean.

 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.
