Frances Griswold excitedly pulled out a rock that crumbled in her hand and showed it to the other researchers Tuesday.

The Central Washington University graduate student worked with fellow student Brian Ostrom to painstakingly examine the layers of soil, mud and sand viewable on the bank of an eroded creek on the Seaplane Base just north of Crescent Harbor this week.

The university researchers, working under the supervision of professor Brea McGinnis, joined with local volunteers and the island’s emergency management organizations for the research all of last week. The purpose: piecing together Whidbey Island’s history of tsunamis, earthquakes and other geological events. Spearheaded by Island County’s department of emergency management, the study’s aim is to educate the island on what to expect and how to be prepared.

The research continues until July 17.
