For this reason, it is often referred to as a tidal wave, [9] although this usage is not favoured by the scientific community because it might give the false impression of a causal relationship between tides and tsunamis. [10] Tsunamis generally consist of a series of waves, with periods ranging from minutes to hours, arriving in a so-called ...
The 2004 Indian Ocean tsunami at Ao Nang, Krabi Province, Thailand. A tsunami (/(t) s uː ˈ n ɑː m i, (t) s ʊ ˈ-/ (t)soo-NAH-mee, (t)suu-; from Japanese: 津波, lit. 'harbour wave', pronounced) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
The wave caught the Japanese off guard, not knowing its origin, and was explained in the book, The Orphan Tsunami. [82] 1707: Nankai, Japan: 1707 Hōei earthquake: Earthquake: On 28 October 1707, during the Hōei era, an 8.4 magnitude earthquake and tsunami up to 10 metres (33 ft) high [83] hit Tosa Province (Kōchi Prefecture). More than ...
Large tsunamis have occurred in the US and will again. A magnitude 9.2 earthquake in the Gulf of Alaska caused damage and loss of life along the West Coast in 1964. More than 150 tsunamis have ...
Smith learned about tsunamis in a geography lesson, [4] [5] two weeks before the tsunami, from her teacher Andrew Kearney at Danes Hill School. [6] [7] [8] While she and her family were walking on Mai Khao Beach, she recognised the signs of a tsunami she had been taught, and alerted her parents. "The water was really, really frothy," Smith said.
They provided a timeline of events, from when a preliminary assessment detected an earthquake at 10:44 a.m. PT to when the NWS National Tsunami Warning Center issued the Tsunami Warning five ...
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.
The effects of a 20° dipping fault along the top of the subducting plate was found to match both the observed seismic response and tsunami, but required a displacement of 10.4 m. [2] The displacement was reduced to a more reasonable value after the extra uplift caused by the deformation of sediments in the wedge and a shallower fault dip of 10 ...
