Local Tsunamis in the Pacific Northwest

In the past century, several damaging tsunamis have struck the Pacific Northwest coast (Northern California, Oregon, and Washington). All of these tsunamis were distant tsunamis generated from earthquakes located far across the Pacific basin and are distinguished from tsunamis generated by earthquakes near the coast—termed local tsunamis.

Could It Happen Here?

The Question: Soon after the devastating tsunamis in the Indian Ocean on December 26, 2004 and in Japan on March 11, 2011, many people have asked, "Could such a tsunami happen in the United States?" This web page summarizes what we know about tsunamis that have struck the U.S. in the past, providing a foundation for estimating tsunami likelihood in the future. Below, we outline the sources of...

Descriptive Model of the July 17, 1998 Papua New Guinea Tsunami

The tsunami that struck New Guinea on July 17, 1998 was the most devastating tsunami since the 1976 Moro Gulf, Philippines, tsunami and may surpass that event (Lockridge and Smith, 1984; Satake and Imamura, 1995). The high reported runups and the tremendous loss of life are of great concern to all, including the international scientific community. Scientists closely examined this event in...
