Give me a museum and I'll fill it. (Picasso) Give me a forum ...
I'll be fascinated when/if Rainier erupts again. Then I will hit you up with questions like "How do you dig your car out from 10 feet of ash" in addition to the interesting plate tectonics.I don’t know if folks here are as fascinated by tectonic plates as I am, but the two plates (Cocos and Nazca) subducting under Central America which create these stratovolcanoes such as Arenal, are remnants of the Farallon Plate which has been almost completely overrun by our North American plate. This overrunning is what created the Rocky Mountains and more all the way to the West Coast. Another Farallon Plate remnant is the Juan de Fuca plate which subducts under Northern California (Cape Mendocino) up into British Columbia, causing our spectacular string of stratovolcanoes such as Mount Hood and Mount Ranier. Those volcanoes are much larger than Arenal.
Oh, when you were in Costa Rica, did you ever stop at the little roadside restaurants? They were cheap back in the early 2000s and always had deep fried plantains on the side, which were quite good and I have not had since.
