A meteotsunami or meteorological tsunami [1] is a tsunami-like sea wave of meteorological origin. Meteotsunamis are generated when rapid changes in barometric pressure cause the displacement of a body of water.
The giant meteorite caused a tsunami to sweep across the planet, the scientists found. Heat from the impact caused the topmost layer of the ocean to boil off, while also heating the atmosphere.
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
When the tsunami's wave peak reaches the shore, the resulting temporary rise in sea level is termed run up. Run up is measured in metres above a reference sea level. [58] A large tsunami may feature multiple waves arriving over a period of hours, with significant time between the wave crests.
A recent study indicates that the meteor that created the 75-mile Lomonosov crater may have produced a "mega-tsunami" that left its mark on the planet. Its rim is the same height as the estimated ...
The tsunami churned up elements such as iron and brought them to the surface. Meanwhile, erosion helped wash coastal debris into the sea and released phosphorus from the meteorite.
It washed over sea walls and drowned over 100 designated tsunami evacuation sites. From historical records, there were three large tsunamis dating back as far as the 17th century, some producing waves dozens of meters high. However, the Japanese based many of their tsunami-defense preparations on smaller tsunamis that had previously hit Japan.
As word of the eruption spread, government agencies on surrounding islands and in places as far away as New Zealand, Japan and even the U.S. West Coast issued tsunami warnings.
