Awakening: volley of recent earthquakes rattling East Java has agitated three volcanoes

December 29, 2011INDONESIAPeople living the vicinity of three volcanoes in East Java have been warned to be on the alert as they were showing signs of increased volcanic activity. The three volcanoes are Mt Ijen, Mt Semeru and Mt Bromo. East Java district disaster management head Timur Siswanto said the authorities were in a state of readiness to handle any volcanic disasters and had established command posts for relief work should any of the volcanoes erupt. He was reported as saying by the local media that Mt Ijen was showing the most activity and that people living in its vicinity had been warned not to come within a 1.5 kilometer raidus of the mountain. Besides the above three, five other volcanoes – Mt Gamalama (Ternate Island, Moluccas), Mt Papandayan (Garut, West Java), Gunung Karangetang (northern Sulawesi ), Gunung Lokon (northern Sulawesi) and Anak Krakatau (Sunda Strait) – were also reported to have started “rumbling.” –My Sinchew

    Curious – Has this happened here before ?? ( for adjoining volcanoes to start ‘rumbling )

    Geologists may consider this ‘normal’, but is there a precedent, for this having happened previously ?

    Alaska Volcano Launches Ash Cloud To 15,000 Feet

    An ash cloud erupted some 15,000 feet into the air from Alaska’s Cleveland Volcano, according to satellite images and the Alaska Volcano Observatory.

    The volcano, located in the Aleutian Islands about 45 miles west of the community of Nikolski, has been upgraded and downgraded several times over the last few months, flaring up in July and erupting in the form of a growing lava dome in August. Following several weeks of activity, the volcano was downgraded before being upgraded again to an alert level of “watch” and an aviation hazard color-code of “orange” in early September. Two months later, the alert level was again lowered after the volcano seemed to quiet down.

    This latest activity comes six days after the most recent update on the AVO website. The AVO said that satellite imagery from about 5 a.m. Thursday confirmed the presence of a detached ash cloud, about 50 miles away from the volcano and moving southeast.

    The last significant eruption of Cleveland occurred in February 2001 and resulted in three ash plumes that reached up to 39,000 feet above sea level and “a rubbly lava flow and hot avalanche that reached the sea.”

    Aviators in the area are encouraged to exercise caution, but the AVO said that the eruption may be an isolated event.

    “Satellite data indicate that this is a single explosion event,” the AVO said, “however, more sudden explosions producing ash could occur with plumes exceeding 20,000 feet above sea level. Such explosions and their associated ash clouds may go undetected in satellite imagery for hours.” http://www.alaskadispatch.com/article/alaska-volcano-launches-ash-cloud-15000-feet
