2001 fissure-forming eruption of Inie Lika volcano, central Flores, Indonesia

A phreato-magmatic eruption occurred at the Inie Lika volcano, Flores Island, Indonesia during January 11-16, 2001 after 95 years of quiescence. This event and consequent fissure formation were described. Inie Lika volcano forms a northern part of the Bajawa Cinder Cone Complex extending over 16 km in the NNW-SSE direction. Ash fall continued for six days and steam discharge continued for two months after the incipience of the eruption. It should be noted that the eruption formed a N16 deg W trending fissure, about 20 m wide and 300 m long, suggesting tensile rifting caused by a thin magmatic dike invasion into a shallow depth.
