Volcanos

Roundup of Global Volcanic Activity

Masaya (Nicaragua): According to local press articles referring to information from INETER, the volcano's activity is on the rise, with "lava being close to the surface". The main crater of the volcano appears covered with debris from rockfalls from the crater walls, but visible incandescence, strong degassing sounds and small flames (from combusting gasses) jetting from between cracks on the floor, suggest that lava might be not far underneath and could again lead to the formation of a new lava lake, last observed in 1999.

Copahue (Chile/Argentina): Ash emissions ceased about a week ago and the volcano has been relatively calm at the surface since. However, a seismic swarm occurred yesterday, sign that the unrest at the volcano is not yet over. According to local press, the swarm contained 103 small quakes during 24 hours, composed by rock-fracturing volcano-tectonic events at 12 km distance from the main crater and at depths of near 6 km.
