New Array Studies Hawaii's Deep Quakes

Summary
- Temporary sensors deployed to monitor West Hawaii seismic activity.
- Study aims to improve understanding of tectonic plate flexure earthquakes.
- Data will aid in better community preparation for future seismic events.

A network of 30 temporary seismic sensors has been deployed near Pu'uhonua o Honaunau National Historic Park in West Hawaii. Researchers from the University of Hawaii are collecting data to better understand seismic activity in the region, following a magnitude-6.0 earthquake on May 22 that damaged approximately 150 structures.
This initiative focuses on "flexure earthquakes," which are caused by the bending of the tectonic plate beneath the islands, a phenomenon distinct from volcanic activity. The sensors, positioned in an area with sparse permanent monitoring, will remain in place for two months to capture aftershocks and provide high-resolution seismic data.
The gathered information is expected to significantly improve the understanding of earthquake causes and geometry in Hawaii. This enhanced knowledge will aid in forecasting seismic risks and improving community preparedness, including building codes and emergency response plans.
