The final part of Etna Week, brought to us by guest blogger Dr. Boris Behncke. Check out Part 1 and Part 2 as well! Etna Volcanic hazards By guest blogger Dr. Boris Behncke. Etna is one of the most active volcanoes on Earth, and a population of nearly one million people dwell on its flanks,…

Etna Week Part 1 Mount Etna – Brief Anatomy of an Exceptional Volcano By guest blogger Dr. Boris Behncke. Italy truly deserves to be called “the Cradle of Volcanology” – not only because it hosts virtually all existing types of volcanoes and volcanic rock compositions, and seven of its volcanoes have had confirmed eruptions during…

Lava flows from Kilauea in Hawai`i move towards a home in Kalapana. Whenever I think about the hazards posed by most lava flows, I tend to think about the opening scene in the Hitchhiker’s Guide to the Galaxy. Developers are planning to knock our hero Arthur Dent’s house down and as a last ditch effort…

Climate, volcanism and the Andes

The northern Chilean and southern Peruvian Andes are full of volcanoes that look stunning – I mean, jaw-dropping details of volcanism litter the landscape. The reason for this is two fold: (1) there is an awful lot of volcanism in the northern Chilean/southern Peruvian Andes (as known as the Central Volcanic Zone) – and has…

Some news over the last few days: The lava flows from Kilauea are moving with a vengeance right now, damaging roads and heading for some structures. The lava flows near Kalapana have moved almost 200 meters since Sunday,…

So, I’ve had requests on the blog to help to do some defining of volcanologic terms on the blog, so I thought I’d try a new column called Eruptions Word of the Day. I’m not sure how often it will run, but let’s give it a try. Eruptions Word of the Day for July 5,…

The latest update from the Smithsonian/USGS Global Volcanism Program! Highlights (not including Taal, Eyjafjallajökull and Bezymianny) include: Another thermal anomaly was spotted on an Kuril Island volcano – this one being Tiatia. The volcano has no seismic monitoring network, so the thermal anomaly is all that has been observed. Lava flows and strombolian explosions continue…

Looking for some volcano news – you’ve found it. A shot of volcano “tourists” near the erupting Pacaya. Photo by the Associated Press. Eruptions reader Dr. Boris Behncke dropped a note that Kilauea has not one but two active lava lakes right now. The lava lakes can be seen on the webcams for the Halema`uma`u…
