HAWAII VOLCANOES NATIONAL PARK – On January 24, USGS Hawaiian Volcano Observatory geologist Matt Patrick gave an After Dark In The Park talk entitled “How Do HVO Geologists Track Lava Flows and Lava Lakes?”. Patrick’s presentation explained the toolkit he and other scientists use to map lava flows and measure lava lakes, and described how scientists continuously improve their methods of tracking volcanic activity.
The video above is part one of two videos taken from Patrick’s presentation, which was recorded by the National Park Service. This one focuses on the activity on the East Rift Zone, which includes Puʻu ʻŌʻō, the June 27 lava flow that threatened Pahoa in 2014, and the current 61g lava flow and ocean entry. Part two will be about the Kilauea summit eruption.
