Mt Rainier- a huge stratovolcano in the US (Washington state to be exact - to be honest before I saw this picture all I knew about Washington state was something to do with Twilight…also, it does NOT house Washington D.C - I know right, most confusing…cut me some slack, I’m Australian for chrissakes). Anyway, from here on out I will associate Washington state with this BEHEMOTH instead - and boy is she beautiful.
Apparently said behemoth is part of the Cascade Volcanic Arc, which formed as a result of SUBDUCTION - Involved is a the low key so-called ‘minor’ plate, known as the Juan de Fuca Plate (frankly the most interestingly named of ALL the tectonic plates and one which I don’t know much about - probably because it sounds like it was named after a gallant, handsome and mysterious Spanish explorer (quite coincidentally, Juan de Fuca WAS a gallant, handsome and mysterious Spanish explorer - I know right, what are the chances).
The Juan de Fuca Plate was slowly SUCKED underneath the larger North American Plate - most of the Juan de Fuca Plate now resides permanently subducted beneath the North American Plate - which must be nice because I’ve heard it’s a lovely place for a holiday home…
Mt Ranier is known to be a particularly DANGEROUS volcano. It has a large amount of glacial ice, which, when melted by lava, can produce huge volcanic mudflows known as lahars. Said lahars have the consistency of concrete and can flow at up to 100km/h.
Sometimes it strikes me just how POWERFUL our Earth is and I am amazed by how little respect we treat it with. Surely with the knowledge we have about the havoc that can be wreaked by…well…GEOLOGY…it pays to learn as much as we can about it!
