Meeting of the Major Risks Commission

The Major Risks Commission - Volcanic Risk Sector recommends paying close attention to volcanic monitoring activities and implementing risk prevention and mitigation measures. While there is no evidence to suggest magma migration towards more superficial levels, analysis of multi-parameter data indicates the continued intensification of the phenomenon of bradyseism. Therefore, the intensification of the current crisis requires regular monitoring of the state of the volcano. The Commission also notes that the seismic activity may persist or increase in the coming weeks. The yellow alert level remains in effect.
