Barujari

For all of you going into withdrawal now that Eyjafjallajökull seems to have quieted down, there are two eruptions of note that aren't in the North Atlantic: Undated image of the Barujari cone at Mt. Rinjani in Indonesia. Arenal in Costa Rica - which is almost always sputtering away - had a more significant explosive and effusive event today. The volcano produced enough ash, bombs and gas emissions - along with 8 lava flows (or avalanches, depending on the source) - to prompt the evacuation of the National Park around the volcano. Arenal has had numerous strombolian eruptions over the last…

Rinjani (above). UPDATE 5/3/2009 11AM (Pacific): The volcano is erupting according to the Jakarta Globe. Seems like the activity so far is confined to small explosions emitting ash and gases. More info as I find it. Rinjani is a popular tourist destination on the…
