THE ERUPTION OF SHEVELUCH VOLCANO, KAMCHATKA, ON MAY 10, 2004
Sheveluch is one of the most active volcanoes of Kamchatka. This volcanic massif began to develop approximately 60,000-70,000 years ago. The historical catastrophic eruptions from this volcano occurred in 1854 and 1964. In 1980, a new lava dome began to grow on the floor of the 1964 explosive crater...

| Summary: | Sheveluch is one of the most active volcanoes of Kamchatka. This volcanic massif began to develop approximately 60,000-70,000 years ago. The historical catastrophic eruptions from this volcano occurred in 1854 and 1964. In 1980, a new lava dome began to grow on the floor of the 1964 explosive crater. The lava dome grew continuously during the 1980-1984 period, after which the growth stopped until 1993. In 1984, a new phase of the dome activity began-occasional gas-ash explosions up to 5-7 km ASL started to occur. Large explosive eruptions from the lava dome took place in 1993 and 2001. On April 22, 1993 ash explosions rose to 16-18 km ASL with pyroclastic flows and mudflows propagating to 5-8 km and 28 km, respectively (Khubunaya |
