Arenal Volcano and Lake, Costa Rica

I don't have too many postcards from Costa Rica so I'm really happy about this one, even if it wasn't mailed directly from Costa Rica in the end.

Arenal Volcano is an active andesitic stratovolcano in north-western Costa Rica around 90 km northwest of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna. The Arenal volcano measures at least 1,633 metres. It is conically shaped with a crater spanning 140 metres. Arenal is geologically considered a young volcano and the age is estimated to be less than 7,000 years. It is also known as "Pan de Azúcar", "Canaste", "Volcan Costa Rica", "Volcan Río Frío" or "Guatusos Peak".

The volcano was dormant for hundreds of years and exhibited a single crater at its summit, with minor fumaroles activity, covered by dense vegetation. In 1968 it erupted unexpectedly, destroying the small town of Tabacón. Due to the eruption three more craters were created on the western flanks but only one of them still exists today. Since October 2010, Arenal's volcanic activity appears to be decreasing and explosions have become rare.
