Are tsunamis measured in magnitude?

The tsunami magnitude, or Mt, is a number used to compare sizes of tsunamis generated by different earthquakes and calculated from the logarithm of the maximum amplitude of the tsunami wave measured by a tide gauge distant from the tsunami source.

What magnitude of earthquake causes tsunami?

Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami. The most destructive tsunamis are generated from large, shallow earthquakes with an epicenter or fault line near or on the ocean floor.

What is the biggest tsunami ever?

How long does a tsunami last?

Large tsunamis may continue for days in some locations, reaching their peak often a couple of hours after arrival and gradually tapering off after that. The time between tsunami crests (the tsunami’s period) ranges from approximately five minutes to two hours. Dangerous tsunami currents can last for days.
