How long did Mauna Loa erupt for in 1984?
9-year
(Credit: Griggs, J. D.. Public domain.) The 1984 eruption of Mauna Loa ended a 9-year period of quiescence. The eruption began suddenly, following a 3-year period of slowly increasing earthquake activity beneath the volcano that included a swarm of earthquakes 5 to 13 km (3 to 9 mi) deep in mid-September 1983.
When was the last time Mauna Loa erupted and what was the damage?
1984
Most recently, Mauna Loa erupted in 1984, but lava flows caused no significant damage except for burying about 16 miles of land owned by the state.
When did fissure 8 start?
New eruptive activity began on Kilauea’s Lower East Rift Zone on May 3, 2018, initiating the most destructive eruption in Hawai`i’s historical record. The initial two weeks of the eruption were dominated by the opening of numerous small fissures, producing spattering and low-volume lava flows.
What is the longest erupting volcano?

What was the worst eruption of Mauna Loa?
What was the worst eruption of Mauna Loa? Mauna Loa has erupted 33 times since 1843, spewing out enough lava to cover 40 percent of the Big Island. The most destructive eruption in recorded history occurred in 1950, when lava raced to the sea at speeds up to 5 miles an hour — destroying homes, businesses, roads and ranches along the way.
How many people were injured when Mauna Loa erupted?
The 1950 eruption of Mauna Loa was the greatest since 1859. Although no lives were lost, it destroyed about two dozen buildings, and buried more than a mile of highway. Its six major lava flows contain on the order of one billion tons of lava. After 1950, Mauna Loa would remain quiet for a quarter century, not erupting again until 1975.
What kind of damage has Mauna Loa caused?
Mauna Loa has also caused earthquake damage. As molten rock enters Mauna Loa, the volcano expands and becomes unstable, setting the stage for earthquakes, some of which are substantial. These earthquakes can also trigger landslides and tsunamis.
When did the Mahukona volcano last erupt?
