How big was the tsunami in Hawaii in 1946?
Significant earthquakes around the Pacific rim have generated tsunamis that struck Hawaii, Alaska, and the U.S. west coast. One of the largest and most devastating tsunamis that Hawaii has experienced was in 1946 from an earthquake along the Aleutian subduction zone. Runup heights reached a maximum of 33 to 55 feet and killed 159 people.
Is there a tsunami warning center in the United States?
NOAA (National Oceanic and Atmospheric Administration) maintains the U.S. Tsunami Warning Centers , which work in conjunction with USGS seismic networks to help determine when and where to issue tsunami warnings. If an earthquake meets certain criteria for potentially generating a tsunami, the pop-up window and the event page for that earthquake…
