Active Planet Belches On!

The weather has sure changed since last I commented on the volcanoes of Earth. August last was cool for Virginia standards but today's blog comes on a February day exploding low temperature records across this volcanically quiet chunk of Earth.  Cold the air may be on Earth's surface but the planet inside still seethes and has found at least 22 spots to set some of that heat free. Six of those spots are on or near the Kamchatka Peninsula, the island arc wannabe still attached to Siberia. My long term guess (and I'm just playing armchair geologist) would be today's activity on the Kurils will continue extending the peninsula, connecting with Japan before being slammed into the Asia massive all the while folding up a new gianormous mountain range. But, worry not, that's 300 million years from now. Today's action gives us a look at that future as the activity rings the ever shrinking Pacific.
Our Ring O Fire tour begins in Chile with Villarrica still on the list but South America is quiet other wise. The lower peninsula of North America (now technically an isthmus) is where the action is on the east side of the Pacific. Pacaya and Fuego fire on in Guatemala and Colima joins Popo back on the Mexican action list. Shishaldin in Alaska's Aleutians joins Kilauea on the US list, far from the mind's of the average American. Japanese citizens are few likely aware of the the outer island activity erupting on 4 isolated islands far south (3) and north of the heart of the archipelago. Indonesians have been mindful of the 3 fire oozing mountains slowly building their archipelago for several years now: Soputan, Sinabung, and Dukono are more likely on the active list than off.
Off the Ring, an occasional visitor to the list, Piton de Fournaise above a hot spot on the Indian Ocean's Reunion island is fired up and reminding locals who's in charge and Iceland's BARDARBUNGA still spews lava on that mid-ocean ridge/hot spot island. The "Bard" has slowed from earlier eruption rates but is likely far from done with this cycle.
Arm chair vulcanology from the deep cold in central Virginia; stay warm out there, just not volcano warm, today on Earth.
