How many people died in the Mauna Loa eruption in 1984?
None Mauna Loa’s most recent eruption occurred from March 24, 1984, to April 15, 1984. No recent eruptions of the volcano have caused fatalities, but eruptions in 1926 and 1950 destroyed villages, and the city of Hilo is partly built on lava flows from the late nineteenth century. The second link below from the USGS provides a graphic of the lava flows. The closest one came within 3.2 kilometers of a prison.
