El Reventador

Ah yes, a reminder that there are other volcanoes erupting around the world than Eyjafjallajökull - but yes, it is true! Here is the latest USGS/Smithsonian Global Volcanism Program Weekly Volcanic Activity Report! Highlights (not including Iceland) include: Another volcano in the Kuril Islands of Russia is showing signs of, well, something. Ketoi was noticed to be experiencing increased fumarolic activity according to satellite images. Ketoi hosts a Pleistocene caldera but has had three historic eruptions over the last few centuries, most recently in 1960, and all of which were explosive…

The flu has retreated and I'm getting back on track. Huzzah! I'll get back to the blog by posting this week's new USGS / Smithsonian Institution Global Volcanism Program Weekly Volcano Report. Looks like some interesting stuff in it ... Looks like there were some small eruptions from Oldoinyo Lengai in Tanzania. The volcano is one of the few (only active?) carbonatite volcanoes in the world, erupting a lava composed primarily of calcium carbonate and sodium minerals with very little silica. It leads to the odd lava that erupt black (and cool ~ 500C) and cool to white, making it one of the…

I did an excellent job of forgetting my notes from GSA 2009, so no wrap up on the meeting until tomorrow, but we do have some new volcano news to digest: The crater of El Reventador in Ecuador in an undated photo. Ecuadorian officials have called for evacuations around El Reventador. The Ecuadorian Geophysics Institute says that the volcano's "activities were measured at a level considered high, with permanent seismic signals indicating explosions while the southern side of the volcano crater could be seen as incandescent.". Three provinces near the volcano were put on alert evacuated as a…

Things were relatively quiet, volcanically speaking, over the weekend and that reminded me, it is just about time to vote on the next in my Volcano Profile series. We've had two volcanoes featured so far: Rabaul in Papua New Guinea and Hood in Oregon. Take a look at the list below and vote for the next in the series! What would you like to see as the next "Volcano Profile"?(opinion polls)

The weekly USGS/SI roundup is out. Highlights (beyond Slamet) include: Explosions (some heard 25 km away) and incandescent blocks that started fires at Galeras, Colombia. Ash and tephra being thrown tens of meters into the air and a 4-m tall spatter cone being built at Pacaya, Guatemala Also in Guatemala, Santa Maria's Santiaguito dome produced ash plumes and explosions. Steam, ash and sulfur odors from the continuing eruption at Redoubt, Alaska. Increased seismicity, steam and ash plumes along with a thermal anomaly at El Reventador in Ecuador

For those of you looking for real volcanic eruption news (no, there was no "Yellowstone eruption"), here is this week's SI/USGS Volcano Activity Report. And speaking of April Fools Jokes, this is by far my favorite (mostly by its combination of volcanoes and baseball. How could you go wrong with two of my favorite things - hat tip to Fletcher for finding the article). Highlights (beyond Redoubt) include: Earthquakes, tremors and steam at El Reventador in Ecuador 12,000-15,000 foot (4-5 km) steam/ash plumes were spotted at Colima, the Mexican volcano. A shockwave was felt 10 km away from Fuego…

El Reventador, the composite volcano in Ecuador, has been producing explosions and ash for the last few days, so says reports from the country's  Geophysics Institute. El Reventador is only 100 km from Ecuador's capitol, Quito, and in 2002 the volcano blanketed much of the city in ash. However, the eruptions currently occurring are much smaller and limited in scope, producing ash and throwing incandescent blocks out near the vent (see above). No evacuations are currently planned. These types of eruptions are typical for El Reventador since 2002, with increased activity every few years…
