Concurrently, lava output at the source ventsdiminished slightly, and the lava became more viscous, resulting in channel blockages and levee collapses that occurred more frequently. 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. Just before 1:00 a.m. on March 25, the tremor amplitude increased to the point that the astronomical telescopes on Mauna Kea, 42 km (26 mi) to the northwest, could not be stabilized because of the constant ground vibration.

It is believed that Mauna Loa has been erupting for 700,000 years or more, emerging from under the sea approximately 400,000 years ago. Six large vent structures eventually formed in this area around the active vents. The residents of Hilo and the scientists at the Hawaiian Volcano observatory now considered the idea of allowing natural events to slow down the flow of lava, as ), Lava fountains feed voluminous lava flows from 1984 eruption of Mauna Loa. Lava channel blockage caused an overflow of the main lava channel leading from the "2,900-m vents" of the 1984 Mauna Loa eruption. The tremors soon became so constant that nearby telescopes on Mauna Kea could not be stabilized due to continuous vibrations. Since 1832, Mauna Loa has erupted 39 times; it's last eruption was in 1984. 1984 - Eruption of Mauna Loa The 1984 Mauna Loa eruption began at about 1:30 a.m on March 25, with lava fountaining in the southwest corner of the summit crater.

Measurements showed the volcano began to inflate shortly after the eruption … Four parallel flows (flows D on map) moved down the northeast flank at speeds as fast as 90 to 215 m per hour (300 to 700 ft per hour. An eyewitness account of the lava flow … All vents uprift from these new ones quickly became inactive, and the eruptive activity was confined to these vents for the next three weeks. Volcano - Volcano - Secondary damage: Property damage from volcanic eruptions is difficult to estimate, because of differing value systems and changes in land use. MAUNA LOA • Print • Add to bookmark • Name: Mauna Loa (in Hawaiian ‘long mountain’) • Location: Hawaii, USA • Height: 4,169 metres (13,679 feet) • Last eruption: March 25th 1984 Mauna Loa is one of the largest volcanoes on Earth. It started in the southwest corner of the volcano's Moku'aweoweo summit crater. Re­peated de­for­ma­tion mea­sure­ments showed that the sum­mit area of Mauna Loa began to in­flate shortly after a brief sum­mit erup­tion on July 5–6, 1975.

Although the lava threatened Hilo, the flow stopped before reaching the outskirts of town. Consequently, the advance of the main flow was arrested. The lava was diverted into a new subparallel flow (flow F on map) and flow E stagnated, temporarily relieving emergency-response officials and residents of Hilo. These factors and the short duration of the eruption helped to prevent lava from advancing into Hilo. At 10:30 a.m., intense steam emissions began along a fracture 1 km (0.6 mi) long farther down the northeast rift zone between the 3,258- and 3,170-m elevation (10,690 and 10,400 ft), but no eruptive fissure formed in this area. The immediate precursors to the eruption consisted of an abrupt increase in small earthquakes and volcanic tremor recorded on seismic stations located near Moku‘āweoweo. The prison was put on alert, because the shorter lava flows were as close as 3.2 km (2 mi) to the prison. Eventually the fissure system condensed to four centers of activity with fountains up to 50 m (165 ft) high. The eruptive fissures migrated rapidly down the southwest rift zone to the 3,886 m (12,750 ft) elevation and across the southern half of Moku‘āweoweo (flow A on map). Map showing lava flows from 1984 eruption of Mauna Loa from the USGS Hawaiian Volcano Observatory .

By 4:00 a.m., lava fountains extended across the northeast half of Moku‘āweoweo and into the upper reaches of the northeast rift zone (flow B on map). And, once upon a time, it was one of the most active: Mauna Loa erupted 33 times between 1843 and 1984. The natural breakdown of levees along the margins of the channelized ‘a‘ā flows diverted lava from the main channel into one or more new subparallel flows. As with casualties, a few eruptions cause staggering damage, while most are much less destructive. (Credit: Lockwood, John P. Public domain.). Since 1984, Mauna Loa has not erupted—its longest quiet period in recorded history.
