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:

- 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 42 years since a VEI 3 eruption in 1968 that killed 89 people.
- Around the world in Indonesia, Barujari, part of the larger Rinjani volcano, had another explosive event, producing a ~2 km / 5,000 foot ash plume that covered nearby farm fields with ash and (apparently) ejected lava (as bombs) a few thousand meters. There have also been lava flows that have entered the caldera lake at Rinjani. The active part of the volcano is a scoria cone (Barujari) inside the caldera and it is this cone that have been erupting off-and-on since the fall of 2009. However, the current eruption has not been large enough to prompt evacuations of people living near the volcano.
- And finally, for those of you desperate for a last gasp (for now) of Eyjafjallajökull, here is a nice EO-1 image of the May 22 explosive eruption, brought to you by the NASA Earth Observatory.
