Lava Eruption and Emplacement: Using Clues from Hawaii and Iceland to Probe the Lunar Past

Thursday, August 2, 2018 at 7 pm at Huntsville-Madison County Main Public Library main auditorium. Our guest speaker will be Dr. Debra Needham, PhD, NASA Research Scientist.

Billions of years ago, the Moon hosted active volcanoes and expansive seas of molten lava. The Earth-facing side of the Moon still preserves evidence of this ancient activity, but scientists continue to ponder how quickly the lava was emplaced, and what significance that volcanic activity has for constraining the Moon’s active history. Remnant features such as sinuous rilles, or lava channels, within these vast plains of solidified lava might hold parts of the answer.

By investigating features we see on the Moon - and the dynamics required to form those features – to those we see actively forming on Earth, we can better understand not only the Moon’s ancient past, but also Earth’s past, present, and future volcanic activity. This talk explores one such ancient lava channel on the Moon, and uses similar features observed on Earth in Hawaii and Iceland to investigate how the lunar feature formed.
