The amount of lava erupted from the vent last night was small, but it represents the first lava erupted from anywhere in Halema`uma`u since 1982. Previous eruptions included lava flowing into the crater from fissure eruptions on its southwest rim in 1974 and 1971 and an 8 month eruption in Halema`uma`u in 1967-1968 that created a lake of lava that covered the entire crater floor.
