First, a key concept - there are two sources of tsunami for Washington coastal waters - a distant source and a local source. Abstract and Figures. DART systems are designed to sense pressure changes at the bottom of the ocean caused by passing tsunamis and to communicate these changes to the tsunami warning centers. A local source - if you feel violent shaking for several minutes, head for higher ground. The U.S. Tsunami Warning Centers issue tsunami messages (above image) to notify emergency managers, the public, and other partners about the potential for a tsunami following a possible tsunami-generating event. LONDON (AlertNet) - In 2004 a tsunami in the Indian Ocean killed almost 230,000 people. Three minutes after the huge 8.9-magnitude quake hit, the Japanese Meteorological Agency issued a major tsunami warning, according to the U.N.'s Intergovernmental Oceanographic Commission (IOC . The centre's tsunami warning services are based on three pieces of technology, each . When a tsunami passes over a pressure . The first article nicely introduces the topic for this lesson, which is whether or not you think a dedicated tsunami warning system should be developed for the Atlantic Ocean. To provide messages as early as possible, the warning centers use preset criteria based on preliminary earthquake information, before a tsunami is detected, to help them decide when . The . Geophysical Research Letters, 28, 397-400. The DART program got a big shot in the arm and ramped up . Japan has learned much from its great earthquakes. The Tsunami Warning System - How Does It Work?
