Two volcanoes, which are part of the arc of volcanos and fault lines encircling the Pacific Basin, have started to erupt on Friday. Mount Karangetang on Sulawesi’s Siau island sent lava, confirmed the local authorities.
Indonesian volcanologists have reported that two volcanoes have spewed fresh lava down their slopes, in the latest of several eruptions in less than two weeks. The scientists are able to watch the natural process from late Thursday. The eruption caused no casualties or damage and the volcanoes’ alert levels were not raised on Sulawesi’s Siau island.
the local population used to watch the volcanoes’ activity – Indonesia is home to 130 active volcanoes, the country lies on the Pacific “Ring of Fire,” an arc of volcanos and fault lines encircling the Pacific Basin.
From late Thursday, volcano Mount Merapi on the main island of Java shot out hot clouds and lava that flowed 2,000 meters down its slopes. Several hours earlier, Mount Karangetang on Siau island sent lava and searing gas out of its crater, prompting evacuation preparations, said volcanologist Kasbani, who uses one name.
To avoid the casualties, the local authorities expanded its danger zone to 4 kilometers from 3 kilometers from Mount Merapi’s crater.
According to the volcanologists, mount Karangetang is partially covered by volcanic smoke as it spews on Siau Island. The 1,784-meter volcano, which currently is on its second-highest alert level, started erupting and spitting clouds of gas and lava on Sunday.
