what happened when mauna loa erupted
Mauna Loa's most recent eruption occurred from March 24 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 19th century.auna Loa has probably been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago.
