The responsibilities of Adak and Sitka were limited to issuing a tsunami warning for ...
The predicted tsunami heights are similar to that of the tsunami from the 1964 Alaska earthquake when it struck the city. [ 4 ] The following year, a report by the U.S. Geological Survey reassessed the tsunami threat posed by the landslide and said that the tsunami 500 m (1,600 ft) offshore Whittier may be slightly over 2 ft (0.61 m) in a worst ...
The tsunami had a maximum run-up height of 10.7 m on Shemya Island, 2.0 m at Amchitka Island, 1.6 m at Attu Island and 1.1 m in northern Kauai, Hawaii. It was also observed in Peru, Ecuador, Mexico, California, Japan and eastern Russia. [1]
The 2004 Indian Ocean tsunami was a teletsunami.. A teletsunami (also called an ocean-wide tsunami, distant tsunami, distant-source tsunami, far-field tsunami, or trans-ocean tsunami) is a tsunami that originates from a distant source, defined as more than 1,000 km (620 mi) away or three hours' travel from the area of interest, [1] [2] sometimes travelling across an ocean.
