WebMar 9, 2011 · The scale for a Tsunami is a Richter scale. The Richter Scale is a scale that measures earthquakes, and Tsunamis are normally made by earthquakes. But be careful, because Tsunamis are normally ... Traditionally, scientists have looked at the earthquake itself—using location, magnitude, and depth—to estimate the size and direction of the tsunami. As an oceanographer, Song knew that historic records had proven this method did not always work well. “The scale of the tsunami can be different from … See more Even if there were no receivers near an undersea earthquake, Song and his colleagues could still detect motion from afar and assess the tsunami likelihood. Although GNSS can … See more NASA Crustal Dynamics Data Information System. Updated daily. Global Navigation Satellite System (GNSS) Data Archive. Greenbelt, Maryland USA. Song, Y. T. 2007. Detecting tsunami genesis and scales directly from coastal … See more Song’s research had proven that GNSS-based tsunami detection is far more accurate than trying to predict a tsunami solely from the size and location of an earthquake.

What is it about an earthquake that causes a tsunami?
WebThe network, managed by JPL, combines global and regional real-time data from hundreds of GPS sites and estimates their positions every second. It can detect ground motions as small as a few centimeters. "This … WebMar 28, 2024 · Most tsunamis are generated by earthquakes with magnitudes over 7.0 that occur under or very near the ocean and less than 100 kilometers (62 miles) below Earth's surface (earthquakes deeper than this are unlikely to displace the ocean floor). Generally, an earthquake must exceed magnitude 8.0 to generate a dangerous distant tsunami.
