Chaiten Volcano, Chile - John Seach
The Government of Chile has announced that the area surrounding Chaiten volcano, in Chile is still not safe, following the large May 2008 eruption. A decision regarding the future of of Chaiten town will be made in coming days. The volcano, only 10 km from the town, started erupting on 2nd May, after being dormant for thousands of years, forcing the evacuation of about 7,000 residents. The government has not dismissed the possibility of relocating Chaiten town and making the whole area a no-go zone for years to come, but many locals have said they want to return to their homes. The latest report indicates the volcano is as dangerous as before, and the news is still not good.

Chaiten Volcano, Chile - John Seach
A lateral explosion occurred at Chaiten volcano on 17th November 2008 at 17:25 hrs. The explosion occurred WSW of the crater, and was possibly related to partial collapse of the dome. This small event was superficial, and was not captured by telemetry stations in the area which transmit data in real time. Gas emissions have been constant at the volcano, with steam and ash rising up to 2 km above the crater.
