The residents of the coastal towns and villages were taken completely by surprise because the tsunami had only been preceded by a relatively weak shock. The magnitude of the tsunami has been estimated as M t =8.2 while the earthquake shaking only indicated a magnitude of M s =7.2. This discrepancy in magnitude requires more than just a slow ...
The term "tsunami" is a borrowing from the Japanese tsunami 津波, meaning "harbour wave."For the plural, one can either follow ordinary English practice and add an s, or use an invariable plural as in the Japanese. [14]
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.
It generated a tsunami that was as high as 167 feet (51 meters), causing an estimated 230,000 deaths. Another magnitude 9.1 earthquake struck in Japan in 2011, creating a tsunami with waves reaching 127 feet (39 meters). The tsunami caused about 18,000 deaths and prompted a nuclear power plant accident. 12/05/2024 17:17 -0500
As word of the eruption spread, government agencies on surrounding islands and in places as far away as New Zealand, Japan and even the U.S. West Coast issued tsunami warnings.
Strong earthquakes can lead to damage, tsunami warnings and more. People can also be injured or killed by damage caused by a quake. Here's what to know about earthquake activity and what causes ...
An example of this was the July 17, 1998, Papua New Guinean landslide tsunami where waves up to 15 m high impacted a 20 km section of the coast killing 2,200 people, yet at greater distances the tsunami was not a major hazard. This is due to the comparatively small source area of most landslide tsunami (relative to the area affected by large ...
A warning alert is the most serious of four tsunami alerts, including a watch alert for a possible tsunami and an advisory alert telling people to stay out of the water and away from the shore. The last time California received a warning alert was 2011 when an earthquake in Japan caused about $100 million in damages along the California coast.
