The first episode had 31 million cubic meters of lava flow into Kīlauea Iki with 1 million cubic meters draining back. During the following episodes, a total of 71 million cubic meters of lava was ejected during a month-long eruption that stopped on December 20, 1959. Only 8 million cubic meters of lava remained, 63 million cubic meters of lava drained back into Kīlauea magma reservoir. Often the lava drainback had a higher rate of flow than the eruptions.
