A Hilo scientist recently returned home from an expedition years in the making. Ashton Flinders is a research geophysicist with the Hawaiian Volcano Observatory in Hilo.
Flinders trained as an oceanographer and spent time aboard the research vessel Atlantis, researching the Bogoslof Volcano in the Aleutian Islands. He led the volcano, earthquake, and landslide hazard component of the expedition, investigating the potential for the volcano to trigger a tsunami.
He spoke with The Conversation about the expedition, starting with the similarities between the region and Hawaiʻi. Flinders said if there’s anything his work has taught him, it’s to believe tsunami warnings. His advice is to pay attention to civil defense.
