ONEMI and SERNAGEOMIN reported that during 5-12 February growth of the lava dome in Nevados de Chillán?s Nicanor Crater was very slow (0.003-0.004 cubic meters per second).
White water vapor emissions, occasionally grayish from included tephra, rose as high as 1 km and drifted in multiple directions.
Crater incandescence was recorded by a webcam each day.
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.
