 Following the event , eruptive events yearly and nearly continuous , a state of activity that remains today . 1967 – 1968 saw a particularly large , 80 @-@ million @-@ cubic @-@ meter , 251 @-@ day event from Halemaʻumaʻu Crater . This event was superseded the very next year by the marathon Mauna Ulu eruption , a large effusive eruption which lasted from May 24 , 1969 to July 24 , 1974 and added 230 acres ( 93 ha ) of new land to the island . After eruptive activity had died down , there was a magnitude 7 @.@ 2 earthquake that caused a partial summit collapse , after which activity did not resume at Kīlauea until 1977 .

 Although volcanic eruptions in Hawaiʻi rarely produce casualties ( the only direct historical fatality due to volcanic activity on the island occurred at Kīlauea in 1924 , when an unusually explosive eruption hurled rocks at an onlooker ) , property damage due to inundation by lava is a common and costly hazard . 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 current eruption produces in three years and reached sea level within four hours of its start , overrunning the village of Hoʻokena Mauka and a major highway on the way there . An earlier eruption in 1926 overran the village of Hoʻōpūloa Makai , and Hilo , partly built on lavas from the 1880 @-@ 81 eruption , is at risk from future eruptions . The 1984 eruption nearly reached the city , but stopped short after the flow was redirected upstream .

 The most recent major eruption at Kīlauea has also proved to be by far its eruption of longest @-@ known duration . The current Kīlauea eruption began on January 3 , 1983 , along the eastern rift zone . The vent produced vigorous lava fountains that quickly built up into Puʻu ʻŌʻō cone , sending lava flows down the volcano 's slope . In 1986 , activity shifted down the rift to a new vent , named Kūpaʻianahā , where it took on a more effusive character . Kūpaʻianahā built up a low , broad volcanic shield , and lava tubes fed flows extending 11 to 12 km ( about 7 mi ) to the sea . Between 1986 and 1991 , Chain of Craters Road was cut , and the community of Kapa ’ ahu , the village of Kalapana , and the subdivisions of Kālapana Gardens and Royal Gardens were lost to the lava . A black sand beach at Kaimu was also engulfed . In 1992 , the eruption moved back to Puʻu ʻŌʻō , but continued in the same manner , covering nearly all of the 1983 – 86 lava flows and large areas of coastline . As of December 2012 , the eruption had produced 4 km3 ( 1 cu mi ) of lava , covered 125 km2 ( 48 sq mi ) of land , added 202 ha ( 499 acres ) of land to the island , destroyed 214 structures , and buried 14 @.@ 3 km ( 9 mi ) of highway under lava as thick as 35 m ( 115 ft ) .

 Eruptions on Mauna Loa are almost always preceded and accompanied by prolonged episodes of seismic activity , the monitoring of which was the primary and often only warning mechanism in the past and which remains viable today . Seismic stations have been maintained on Hawaiʻi since the Observatory 's inception , but these were concentrated primarily on Kīlauea , with coverage on Mauna Loa improving only slowly through the 20th century . Following the invention of modern monitoring equipment , the backbone of the present @-@ day monitoring system was installed on the volcano in the 1970s . Mauna Loa 's July 1975 eruption was forewarned by more than a year of seismic unrest , with the HVO issuing warnings to the general public from late 1974 ; the 1984 eruption was similarly preceded by as much as three years of unusually high seismic activity , with volcanologists predicting an eruption within two years in 1983 .

 In advance of Hurricane Estelle , the National Weather Service issued a hurricane watch and high @-@ surf advisory for the Island of Hawaii . More than 200 people evacuated from their homes . Huge waves crashed on the shores of the Big Island on the afternoon of July 22 . The high waves washed away five beachfront homes and severely damaged dozens of others on the beach resort of Vacation Land . The total damage was around $ 2 million ( 1986 US $ ; $ 4 @.@ 32 million 2016 USD ) . However , only two deaths reported from the storm , both of whom drowned offshore Oahu .
