1940 Mauna Loa Eruption Film

Vintage film of Mauna Loa eruption during 1940 by Harold T. Stearns, a USGS Hydrologist-Volcanologist.

An eruption of Mauna Loa is something everyone fears and hopes for. This enormous volcano will erupt again, almost certainly within our lifetimes, possibly even the next decade. The last eruption was in 1984, the mountain has been quiet for well over two decades now, an uncharacteristically long period of quiescence. When it does erupt this volcano is capable of emitting huge volumes of lava, that reach the sea quite quickly down the steep slopes A dangerous mountain to be wary of.

  1. Stearns is quite a famous name when it comes to classification of Hawaii soils. He and MacDonald basically “wrote the book” on them back in that time frame.
