Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.
A tsunami (plural: tsunamis or tsunami; from Japanese: æ´¥æ³¢, lit. harbor wave; English pronunciation: /tsuËËnÉËmi/) , also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.arthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.
A tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing water. Tsunami are sometimes called seismic sea waves, although they can be generated by mechanisms other than earthquakes. 4.5 hours later the same tsunami reached the Hawaiian Islands after traveling at an average speed of 659 km/hr. 2  As it approached the city of Hilo on the Big Island, it slowed to about 47 km/hr (note that even the fastest human cannot run faster than about 35 km/hr) and had a run-up of 18 m above normal high tide.
