Igan S. Sutawidjaja
Abstract
Egon volcano, which had been dormant since 1907, became active in late January 2004. It was preceded by some crumbling sounds at mid night on January 27th , 2004 that heard by the people who live in Baokrengit village, close to the volcano. No experience of volcanic eruption in almost two human generations caused a panic for the people when they saw a smoke column above the summit in the morning.
A phreatic eruption resulted many small craters surrounding the main crater, erupted ash and mud and distributed within the main crater. Ash analyses show altered materials of alunite, pyrite, kaolinite and anhydrite, there was no magmatic materials erupted to the air. At least 12 craters were identified with a different dimension between 5 to 10 m in diameter.
