The trouble with being a volcanohead is that, as far as I know, volcanohead hunting season lasts almost all year, Also there’s no bag limit, and though our numbers and subtle but wily tactics ensure our survival, all volcanoheads have an innate fear of becoming extinct. Outwitting this Search Party is not easy, but in my defence, I once again ran and hid in a baited field..a volcanoey (even by subduction zone standards) place called the Kamchatka peninsula, at a volcano called Zheltovsky.
Zheltovsky is one of the lesser studied volcanoes of the world. He has a rather typical biography as well. Born in the southern end of the peninsula out of a wide Pleistocene shield volcano’s caldera, he began emerging around 8,000 years ago to become a stratovolcano. Inevitably, his explosive temprament led him to form his own 1.6 km wide summit crater. There are also a number of flank domes and cones on his flanks, mostly on his northwest side.
His broad summit crater would perhaps be more impressive if not for being partially filled by four large extrusive lava domes. Its last explosive eruption in 1923, a VEI 3 event, also produced lava that flowed down the volcano’s southeast flank as well as into the summit crater.
Zheltovsky may have been active again in 1972. Some fumarolic activity and a possible phreatic explosion was reported but this activity remains unconfirmed.
Congratulations to Aficientifico, who once again found me on the first day and piled on lots of Extra Credit points. Also, welcome to the fun, Chris Cookie Cook, who plays via Facebook. I hope to see you again next time. As for next week’s challenge, my temporary work schedule might dictate whether it happens as scheduled, but I should know by Saturday evening how my next week will go. I will include an announcement about VVVc #31 along with some Weekend Whiimsy fun.
