Don Swanson, USGS senior geologist and former scientist-in-charge at the Hawaiian Volcano Observatory, will give a presentationâ “Explosive Eruptions at Kilauea: A Wolf in Sheep’s Clothing,” from 7-8:30 p.m. on Monday, Feb. 27, at the Lyman Museum.

Most people are surprised to learn that Kilauea is a violent volcano, yet the number of known fatalities from explosive eruptions at Kilauea is greater than at any other volcano in the United States. In fact, Kilauea erupts explosively about as often as does Mount St. Helens; the eruptions are generally smaller, but the impact could be significant, given that 5,000 people visit the top of the volcano each day.

Swanson will describe this volcano’s explosive past and its implications for the future in the context of recent findings that, for the past 2,500 years, Kilauea has been in a potentially explosive mode more than half the time.
