These colossal waves, known as Mega Tsunamis, are of such immense magnitude that they can tower several hundred meters in height, hurtling at the velocity of a jet aircraft and penetrating as far as 12 miles (20 kilometers) inland. Over the past half-century, researchers have unearthed compelling evidence of a hitherto unrecognized natural phenomenon resembling traditional tsunamis but capable of inflicting unparalleled devastation along coastlines. The prospect of such massive waves, potentially triggered within the Atlantic Ocean over the next 500 years, poses a formidable threat to the East Coast of America, North Africa, and Europe.
How far did the 2004 tsunami travel?
The Indian Ocean tsunami, which struck on December 26, 2004, unleashed devastation across vast distances, reaching as far as 3,000 miles to Africa with lethal force, claiming lives and laying waste to property. Reports from Indonesia revealed that many witnessed animals fleeing to higher ground mere minutes before the tsunami’s arrival, yet remarkably few animal casualties were discovered in the aftermath. The cataclysmic event was triggered by a colossal earthquake estimated to have unleashed energy equivalent to 23,000 Hiroshima-type atomic bombs. With an epicenter situated in the Indian Ocean near the western shores of Sumatra, the earthquake registered a staggering magnitude of 9.0.
How fast does a tsunami travel on land
As a tsunami approaches shallower waters near the coast, its speed decreases, causing its wavelengths to shrink while the height of the waves increases, accompanied by intensified currents. Upon reaching the shoreline, most tsunamis decelerate to the speed comparable to that of an automobile, roughly ranging from 20 to 30 mph (30 to 50 km/h).
Once initiated, tsunamis emanate outward in all directions from their point of origin. Unlike ordinary wind-driven waves, which primarily affect the ocean’s surface, tsunamis propagate throughout the entire depth of the ocean, from its surface down to the seabed. In fact, colossal tsunamis have the capacity to traverse entire ocean expanses.
How far inland would a 3000 ft. tsunami go
In the past fifty years, scientists have uncovered ample evidence in nature of a previously unidentified natural phenomenon. Although resembling “traditional” tsunamis, this phenomenon could potentially unleash an unprecedented level of devastation along coastlines. A colossal wave of this magnitude might likely be triggered in the Atlantic Ocean within the next 500 years, presenting a formidable threat to the East Coast of America, North Africa, and Europe.
Tsunamis can travel up to miles per hour
In the depths of the ocean, tsunamis can surge forward at incredible speeds, comparable to those of a jet plane, exceeding 500 mph (800 km/h). Remarkably swift, they possess the capacity to traverse entire oceans in less than a day. Once triggered, the energy of a tsunami permeates throughout the water column, disregarding the ocean’s depth. Characterized by a sequence of extraordinarily lengthy waves, a tsunami’s propagation mirrors the outward expansion of ripples resulting from a stone cast into a pond. The wavelength and period of these waves hinge on the mechanism and scale of the originating event. For instance, tsunamis generated by expansive earthquakes exhibit greater initial wavelengths and periods compared to those induced by localized landslides. Typically, the period of tsunami waves ranges from 5 to 90 minutes. As these waves journey across the ocean, their crests may span anywhere from a few to hundreds of kilometers apart. Upon nearing the coastline, the wavelength of the waves diminishes while their height escalates.
