delay. Further support comes from a 70-seconds long rumble recorded in the middle of 
the Pacific soon after the earthquake. This sound lasted too long to have come from a 
small aftershock and may have represented a seafloor slide.

Unfortunately, tsunamis cannot be stopped or prevented. However, effective warning 
systems might save hundreds of lives. In the United States, the National Tsunami Hazard 
Mitigation Program has been developed to reduce the impacts of tsunamis along the 
U.S. Pacific Coast. One goal of this program is to improve the tsunami warning systems. 
Components of such systems include seismic sensors that warn of large earthquakes 
and oceanic sensors that detect tsunamis crossing the ocean. Destructive tsunamis need 
to be detected quickly so that warnings can be issued to allow the orderly evacuation of 
coastal communities in the path of the waves. Of course, evacuation can only save lives 
if the tsunami is triggered far enough away to give advanced warning.

Write the name and the year in the box on your answer sheet.
