The 1984 eruption of Mauna Loa was a Hawaiian eruption in the U.S. state of Hawaii that lasted from March 25 to April 15, 1984. It ended a 9-year period of quiescence at the volcano and continued for 22 days, during which time lava flows and lava fountains issued from the summit caldera and fissures along the northeast and southwest rift zones The lava was visible from Hilo, unnerving citizens who were all too aware that the city itself is built on comparatively young lava flows. An 1881 eruption of Mauna Loa had come within 1.1 miles of the city's bayfront. Two other eruptions had also threatened the site of the city in the last millenium, so the danger was by no means unprecedented Hawaiian-type eruptions usually produce extremely slow-moving flows that advance at walking pace, presenting little danger to human life, but this is not strictly the case; Mauna Loa's 1950 eruption emitted as much lava in three weeks as Kīlauea's recent eruption produced in three years and reached sea level within four hours of its start, overrunning the village of Hoʻokena Mauka and a. Mauna Loa erupted most recently in March-April 1984.
