After efforts to map the seafloor surrounding Hawaii began in 1977, scientists discovered the debris of a multitude of ancient gigantic landslides. Geophysicist Gerard Fryer will show the impact these landslides had in a presentation at Windward Community College's Hale Imiloa March 29 at 1 p.m.

Humongous landslides tend to create humongous waves. By identifying and studying the deposits left on the islands be these waves, geophysicists like Fryer are beginning to think these landslides are driven by climate change. The focus of this month's presentation will explain why scientists do not expect another island-shifting landslide until after the next Ice Age.

The presentation is a part of the Spring Community Forum in Chemistry series.
