An explosion marked the Nevados de Chillan on August 8 at 12:12 local / 16:12 GMT, accompanied by a gray ash plume high about 1,500 meters, and ballistic projections visible on the thermal camera.

An earthquake of a superficial hypocentre, estimated at 200 meters marked the explosive episode and testifies to the instability of the volcanic system, and the evolution of the dacitic dome.

A video from the slopes of the ski resort is available on Facebook / https://www.facebook.com/quillonaldia/videos/1090806864401814/

The technical alert remains nevertheless to Naranjo.

A strong explosion, accompanied by avalanches around the crater, fallout and shockwaves, occurred on August 8 at 21:20 local. Incandescent materials were ejected at 4,800 m Asl., Evening about 1,100 meters above the summit; the ash plume moved 12 km to the west.

This is the first strong explosion recorded in the last six weeks.

In the eastern rift zone of Kilauea, the situation seems frozen ... for now.

Only a weak incandescence remains visible in the cone on the fissure 8. The thermal images of the lava field reflect a drop in activity level, compared to the previous 3 days; the lava, however, is present under the crust at various points.

Hurricane Hector's approach is already manifested by strong winds and larger waves ... observations and images will be scarce over the lava field in the next few hours.
