Today’s Earthquake Fact

During post-tsunami field surveys, inundation and runup measurements are taken to describe the tsunami effects. Inundation is defined as the maximum horizontal distance inland that a tsunami penetrates. Runup is the maximum vertical height above mean sea level that the sea surface attains during a tsunami. Actual tsunami wave heights can be measured from the amplitude of the wave signals seen on sea level or tide gauge instruments.
