Sarigan

This week I welcome Dr. Ed Kohut as a guest blogger here on Eruptions (while I am off in the Sierras doing some field work). I've known Ed for 10 years now - we were both graduate students in igneous petrology at Oregon State University - and we are both Massachusetts natives. Ed was in the Coast Guard before getting degrees at University of Rhode Island and Boston University before heading of to Oregon State for a Ph.D., where he worked on melt inclusions in minerals. One of his major research areas is magmatism in the Mariana Islands and he was nice enough to put together a look at the…
Have guests in town, so I'm a little busy, but you can hopefully keep entertained with the latest Smithsonian/USGS Global Volcanism Program Volcanic Activity Report. Chile's Melimoyu volcano. The highlights (not including Taal and Eyjafjallajökull) include: Alaska's Cleveland volcano has been reduced to and alert status of "unassigned" (used when a volcano is not closely monitored so AVO doesn't know what exactly is "background") after a few weeks of activity. The same was done for the submarine volcano south of Sarigan in the Marianas Islands after no signs of activity since the eruption a…
The level of news-frenzy on some of the recent volcanic eruptions has died down, but if you're looking to see information on the many rumbling going on worldwide, look no further. Here is this week's Volcanic Activity Report put together by Sally Kuhn Sennert of the Global Volcanism Program. Highlights - not including Pacaya, Yasur, Tungurahua and our friend in Iceland - include: The eruption in the Marianas apparently came from South Sarigan volcano - at least according to the best guess by folks who work in the Marianas. This submarine volcano apparently shows evidence of young lava flows,…
Sarigan Island in the northern Mariana Islands. An undersea eruption appears to be underway south of the island. Thanks to the watchful eye of Eruptions readers, we had an inkling of this eruption the other day, but now we have confirmation that an undersea eruption is underway in the northern Mariana Islands. The exact volcano erupting is unknown, but it appears to be between Anatahan and Sarigan (see below) - both active volcanoes in the Marianas - at a depth of 300 meters. The eruption has been described by the USGS as hot water vapor and an ash plume that might have reached as high as 12…
Sarigan Island in the Marianas - your MVP #4. I have to hand it to all of you, each time I've tried to make the Mystery Volcano Photo a challenge, you beat it with flying colors. The photo is, in fact, of Sarigan in the Mariana Islands (thanks to Dr. Ed Kohut for providing the photo). Eruptions reader Cam got the volcano on the second guess, leaving our current standings at: MVP Standings volcanista - 1 Ralph - 1 Elizabeth - 1 Cam - 1 everybody else - 0 Not much is known about Sarigan - it is an island composite volcano in the Mariana Islands. The last few eruptions have produced lava dome…
