 Mount Unzen - Wikipedia, the free encyclopedia
Unzen's most serious eruption came in 1792, with a large dacitic lave flow coming from Fugen-dake.
The volcano was designated a Decade Volcano in 1991 as part of the United Nations' International Decade for Natural Disaster Reduction, due to its history of violent activity and location in a densely populated area.
This was attributed to hydrothermal circulation accelerating the cooling of the magma over the nine years since the end of the eruption.

Mount Unzen’s reawakening produced a new lava dome at its summit.
Mount St. Helens’ eruption on May 18, 1980, eliminated 1,300 feet of its summit, spewing ash up to 950 miles eastward and leaving 57 people dead.
“Mount St. Helens had a large eruption, and then for the next five to six years a lava dome grew in the crater, spawning small to moderate-sized eruptions as the dome collapsed or blew apart,” said Ramsey.
