Tsunamis

On January 19, 1968, a thermonuclear test, codenamed Faultless, took place in the Central Nevada Supplemental Test Area. The codename turned out to be a poor choice of words because a fresh fault rupture some 1200 meters long was produced.
No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future.
Large tsunamis have occurred in the United States and will undoubtedly occur again.
Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at the site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate.
NOAA 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.
Tsunamis are ocean waves triggered by large earthquakes that occur near or under the ocean, volcanic eruptions, submarine landslides, and by onshore landslides in which large volumes of debris fall into the water.
Estimate what EQ of what size are likely to occur (geology)Given the EQ size we then estimate what the shaking will be (seismology)Given the shaking estimate the response of different types of buildings (EQ engineering).
A fault is a fracture or zone of fractures between two blocks of rock.  Faults allow the blocks to move relative to each other.  This movement may occur rapidly, in the form of an eart
Although earthquake magnitude is one factor that affects tsunami generation, there are other important factors to consider. The earthquake must be a shallow marine event that displaces the seafloor.
