Chilean state geological service SERNAGEOMIN announced on 25 April that the alert level for Llaima is being raised from Yellow Level 3 to Yellow Level 4 because of ‘the occurrence of earthquakes with high energy levels and tremor signals with durations of up to 20 minutes’. OVDAS volcanologist Gustavo Fuentealba is quoted in El Mercurio as warning that the crater of Llaima remains obstructed (as confirmed in ONEMI’s bulletin of 25 April, which reports the findings of an overflight of the volcano), and that this ‘increases the risk of a new eruption’. There is no change in the appearance of the volcano; fumarolic activity continues from the summit crater.

This is the latest OVDAS report about Llaima. Note that this documents talks until 20 April, 3 days before increasing alert level, so the activity comes from a few days ago.
