In late July, The sixth largest earthquake in recorded history Kamashka Peninsula hit Russia. The 8.8 earthquake led to a tsunami that sent waves across the Pacific, which led to widespread warnings and some evacuation orders.
The data released on Thursday August 14, by NASA Earth, picks up this global event with amazing details. The Swot satellite and ocean (SWOT), a joint venture between NASA and the French Space Agency CNES (Spatial National Center), recorded the leading edge of the tsunami about 70 minutes after the earthquake was hit. In the moving drawing below, the signs of red spots place the darkest places where the wave rose more than 1.5 feet (0.45 meters).

“A 1.5 -foot wave may not look much, but a tsunami are waves that extend from the sea floor to the surface of the ocean,” Ben Hamiltton, the ocean designer at NASA’s jeta drive in southern California, He said In the launch of the NASA Earth Observatory. “What may be just a foot or two in the open ocean can become a 30 -foot wave in the shallow waters on the coast.”
Earthquakes lead to tsunami when they are large enough to displace large amounts of ocean water. Pictures of the entire water column about the disorder suddenly to lift. The tsunami caused by this earthquake was 8.8 actually Less powerfulBut it is still sending waves up to 13 feet (4 meters) to coastal cities in Kamchatka near the earthquake center, according to BBC. One person caught the massive bloating on the video while he was walking his dog along the coastal slopes.

Other affected sites, including the American West Coast, Hawaii and Japan, have witnessed much smaller waves. Tsunami warnings are quickly reduced or raised in most areas.
By collecting data about the height, shape and trend of tsunami, Swot helps scientists at the NOAA Center for Tsunami Research to improve their expectations. “The satellite notes help researchers unlike the best tsunami engineering, and in this case, they also showed us that the Tsunami’s expectations in NOAA were correct for the money,” Josh Willis, an ocean designer at the NASA jet laboratory, said in the statement.
Noaa alerts alerts to coastal societies that are likely to be on a tsunami based on the outputs of their expected model, so it is important to be as accurate as possible. The chief scientist Vasily Titov, when he was the Tsunami Center in SWOT, said when the Tsunami Research Center tested its model with Swot Tsunami data, the results were exciting. “It indicates that SWOT data can significantly enhance the operational tsunami.”
