Nevados de Chillan (Chile) – Report for 24 April-30 April 2019

SERNAGEOMIN reported that the lava dome in Nevados de Chillán?s Nicanor Crater continued a cycle of slow growth and partial destruction from explosions during 23-30 April. The pulsating, generally white, emissions were sometimes gray and rose no higher than 900 m above the crater rim and drifted NW, S, and SE. Nighttime webcam data showed incandescent ejecta around the crater. The Alert Level remained at Orange, the second highest level on a four-color scale, and residents were reminded not to approach the crater within 3 km. ONEMI maintained an Alert Level Yellow (the middle level on a three-color scale) for the communities of Pinto, Coihueco, and San Fabián.
