1) Here the eruptions sorted by number of fatalities: 80 (Kilauea, Hawaii, 1790) 2 (Kilauea, Hawaii, 1975) 2 (Kilauea, Hawaii, 2001) 1 (Kilauea, Hawaii, 1925) 1 (Kilauea, Hawaii, 1993) However, the fatalities indicated in this list contains the various eruption related causes: "In the past 200 years, there have been over 200,000 deaths in volcanic eruptions. Four causes resulted in 91% of the fatalities - famine and epidemic disease (30%), pyroclastic flows (27%), lahars (17%), and tsunamis (17%)." Source and further information: http://www.volcanolive.com/fatalities.html This would make a total of 86. 2) However, according to another page, there were only 2 estimated volcano related fatalities between 1900 and 2002. 3) "The volcano exhibits frequent eruptions, although written records stretch back only to 1820. In an earlier episode around 1790, a KÄ«lauea eruption killed a party of warriors and their families." Source and further information: http://en.wikipedia.org/wiki/K%C4%ABlauea#Eruptive_activity "Volcanic eruptions in HawaiÊ»i rarely cause fatalities—the only fatality due to volcanic activity there in the last century occurred at KÄ«lauea in 1924, when an unusually explosive eruption hurled rocks at onlookers, killing one. However, property damage is common. Mauna Loa is a Decade Volcano, which means it has been identified as worthy of particular research in light of its frequent eruptions and proximity to populated areas. Many towns and villages near the volcano are built on lava which has erupted in the last two hundred years, and there is a very strong likelihood that future eruptions will cause damage to populated areas."
