Volcanos

Roundup of Global Volcanic Activity:

Turrialba (Costa Rica): New ash emissions occurred yesterday and produced light ash falls in the outskirts of San José, in the areas of Guadalupe, Tres Ríos, Curridabat, and Ipis (at about 30 km distance). The relatively strong ash emissions occurred from about 08:50 until 10h30 local time and were produced from two vents at the volcano. At the moment, it is not yet clear whether some of the ash is from new magma or if it is only pulverized older rock (i.e. the product of phreatic activity). Analysis of ash samples will probably tell this very soon. The volcano has in the recent past occasionally emitted ash, such as last in Jan 2012, but had otherwise only been in a state of strong degassing recently. It is known for high SO2 emissions that damage vegetation around the crater and at nearby plantations.
