Eruptions

Archives for July, 2009

Mayon erupting in August 2004. The increasing unrest at Mayon in the Philippines has prompted National Disaster Coordinating Council (NDCC) to recommend the evacuation of over 75,000 people from around the volcano. This, however, will only happen if the activity at the volcano continues to increase. The volcano currently sits at Alert Level 2 (increasing…

Interview on the Reef Tank

I haven’t done too many interviews in my day, so this was kind of fun. Wander on over to The Reef Tank and you can read my interview – mostly about the role of water in its many forms on Earth in understanding magmatism and volcanism. Thanks to Ava from The Reef Blog for the…

Friday Flotsam

Another fun weekend for me analyzing zircon on the SHRIMP-RG at Stanford University! I really know how to live it up during the summer.

Hydrothermal fields are tricky beasts. They can wax and wane as the magmatic system heats and cools, as the water table rises and falls and as other events such as earthquakes or explosions might change the conduit systems. Changes are relatively common, as we’ve seen in recent events in the Yellowstone Basin and with the…

All the volcano news that is fit to print, all thanks to the USGS/Smithsonian GVP! Highlights (not include Manda Hararo, Kilauea and Mayon) include San Miguel in El Salvador has been experiencing increased seismicity. The last time the volcano erupted was in 2002. A pilot spotted a ~10,000 foot / 3 km ash plume emanating…

Wednesday Whatzits

Two papers submitted, one to go. Keeps you quite busy, let me tell you. Lava flow from a 2006 eruption on Mayon in the Philippines. A few bits of news today: A few more details about the ongoing watch of Mayon in the Philippines . There have been apparently no changes in the shape of…

A quick update on the rockfall in the Halema`uma`u (got it right this time!) Crater at Kilauea. Last week a rockfall blocked the vent that had been glowing for most of the year from the lava below, but the debris clogged the vent, producing minor accidental tephra explosion. Lava in the recently “clogged” Halema`uma`u vent…

Increasing concern about Mayon

Sorry about the lack of posts – the holiday and “real life” had stepped in the way. On with the news! Mayon Volcano in the Philippines with Legazpi City in the foreground. Mayon, one of the most active volcanoes in the Philippines, is causing concern due to increasing signs of activity. Renato Solidum, the director…

There is a bit of a buzz today about significant rockfalls that occurred in Halema’uma’u Crater at Kilauea on June 30th. Some articles have suggested that the rockfall has “snuffed…

New eruption in Ethiopia!

Three days ago, I received an email from Eruptions reader Gijs de Reijke who was curious about something he noticed in the daily OMI SO2 images: OMI sulfur dioxide map over Ethiopia for June 30, 2009. Now, I wasn’t quite sure what to make of it other than the fact that there was an awful…
