East Epi is a submarine caldera. Between 1920 and 1988, five historical eruptions have been confirmed and six more are suspected. Most of these eruptions are non-explosive (VEI=0) and lasted a few days to a few months. The 1953 eruption was explosive (VEI=3) and constructed a new island.
Volcanic activity renewed at East Epi caldera after 6 years of quiescence.
An eruption was reported in early March.
