Soufrière Hills century in Montserrat. When pyroclastic flows and mudflows began occurring regularly, the capital, Plymouth, was evacuated, and a few weeks later a pyroclastic flow covered the city in several metres of debris. The first phreatic explosion in this new period of activity occurred on 21 August 1995, and such activity lasted for 18 weeks until it caused an andesitic lava dome formation. This was initially confined by a sector-collapse scar. This period lasted for another 60 weeks, after which there were major dome collapses and two periods of explosive volcanic eruptions and fountain-collapse pyroclastic flows. The explosion blanketed Plymouth, away,
Karymsky (volcano) an ongoing non-stop eruption occurring, and is the peninsula's most reliable volcano, which has been erupting continuously since 1996. Karymsky (volcano) Karymsky (, "Karymskaya sopka") is an active stratovolcano on the Kamchatka Peninsula, Russia. It is the most active volcano on the Kamchatka Peninsula, as well as the most active volcano of Kamchatka's eastern volcanic zone. It is named after the Karyms, an ethnic group in Russia. Karymsky is a symmetrical stratovolcano rising within a 5-km-wide caldera that formed during the early Holocene. Much of the cone is mantled by lava flows less than 200 years old.
