Mauna Loa volcano is one of the tallest mountains in the world. When measured from its base on the sea floor, it rises more than 17,000 m (56,000 feet). Mauna Loa volcano is approaching its longest historical period of inactivity, 25 years. Mauna Loa volcano is spreading because its size is large compared to the thin basal layer.

Mauno Loa 1984 Volcanic Eruption
Early on the morning of 25th March 1984, a magnitude 4 earthquake accompanied an eruption of Mauna Loa volcano. Lava fountains were visible in Mokuaweoweo caldera. This was followed by fissures opening on upper NE Rift Zone. By 29th March, lava flows reach within 6.5 km of Hilo. The eruption finished on 15th April 1984.

The lava delta and nearby areas remain dangerous and should not be approached. Bench collapse can occur without warning, and result in explosions and ejection of hot lava, and local waves.
