Geothermal Energy Up Close: A New Volcano Forms in Iceland

From an interview with Benjamin D. Smith
About Ben Smith: Ben is a geologist pursuing a Master of Science Degree in Sustainable Energy at Reykjavik University in Iceland concentrated on geothermal energy.
This volcanic area near Reykjavik, Iceland last erupted about 900 years ago. Ben is certainly blessed with an amazing opportunity to watch a new volcano form here in person. This small new volcano has yet to be officially named. It started from a ground-level fissure and is steadily growing. You can actually observe its growth in realtime. No one knows how long the eruption will continue. On a clear night, you can see its glow from Reykjavik. Unconfirmed local reports say that the volcano is growing over the gravesite of the valley’s namesake.
Earthquakes were experienced for about a month before the eruption and additional earthquakes may occur. Two types of basalt are forming as the lava cools: pahoehoe and aa. Pahoehoe is smooth and flowy basalt whereas, aa is a sharp-edged and brittle basalt. The color of the lava is indicative of its temperature. Dark red lava is about 800 degrees C; bright orange-red is about 1,000 degrees C, and bright yellow is about 1,150 degrees C. Ben says that it all feels very hot up close as though you are being sunburned. While many volcanoes are accompanied with a pronounced sulphur smell, they did not notice any significant odor.
The lava flow has not reached the ocean; if it does, there is a risk that significant airborne ash from the sudden cooling could adversely effect air travel. A hike of about 3 hours is required to reach the volcano with part of the route on a closed road. The area is closed today because strong winds trapped volcanic gases in the surrounding valley. I am hoping that the eruption lasts long enough for me to see it myself. Here are some cool (actually “hot”) photos and videos that Ben captured yesterday.
