What were the effects of Mauna Loa eruption?
Eruption spectators caused traffic congestion in Hilo, and some risked their safety to trespass into the closed area. Some power poles and lines were destroyed by a lava flow, impacting electrical service to a relay station and the National Oceanic and Atmospheric Administration (NOAA) Mauna Loa Observatory.
How did the Mauna Loa affect Hawaii?
The eruption of Mauna Loa in the spring of 1868 and the deadly phenomena surrounding it were one of the greatest natural disasters in Hawaiian history. 77 Hawaiians died in the associated tsunami and landslides. As with most eruptions of Mauna Loa, the 1868 eruption began at its summit caldera, Moku’āweoweo.
What are the 5 effects of volcanic eruption?

What happened after Mauna Loa erupted in 1984?
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.
What damage did Mauna Loa cause in 1950?
In 1950, the eruption of Mauna Loa sent voluminous amounts of lava downslope through small villages in upper Ho’okena, destroying homes, a gas station, lodge, church and a cemetery. In 1984, flows came within four miles of Hilo, sparing the town but destroying the forests above.

When did Mauna Loa last erupt and what was the damage?
What are the secondary effects of a volcanic eruption?
The secondary hazards are the indirect consequences such as lahars, tsunamis and epidemic disease and post-eruption famine. During eruptions, volcanoes release a huge amount of pyroclastic rocks or tephra into the atmosphere and these clastic deposits will fall back and accumulate on the surrounding Earth’s surface.
