Tsunamis occur with the most frequency in the Pacific Ocean and around Indonesia. This is because of the properties of the Pacific Rim; it has a high number of active submarine earthquake zones, which are a major factor in the occurrence of tsunamis. However, it is also possible for tsunamis to occur in other places. The Mediterranean Sea and the Caribbean Sea are also both susceptible to tsunamis.Know More
A tsunami is an incredibly large wave that is caused by underwater volcanic activity or by earthquakes that occur along fault zones underwater. These can cause water levels to rise rapidly and can be incredibly deadly. Tsunamis also do a vast amount of lasting damage to the property and economies of a region. Because of the specific circumstances that lead to the creation of a tsunami, there are certain places that are much more susceptible to these natural disasters than others.
According to the National Oceanic and Atmospheric Association's Center for Tsunami Research, most tsunamis happen in the Pacific Ocean and around the Pacific Rim. This area has enough underwater earthquake activity to cause an increase in the risk of tsunami development. Indonesia is at a high risk for tsunamis for this reason as well.Learn more about Tsunamis
Tsunamis usually occur when earthquakes take place underneath the ocean at tectonic plate boundaries, or when volcanic eruptions or landslides take place in the ocean. Underwater earthquakes cause the ocean floor to fall and rise abruptly, which results in large volumes of water being displaced. This displaced water then forms into massive rolling waves that eventually become a tsunami.Full Answer >
The height of a tsunami is determined by the depth of water at the point where it starts. Tsunami wave heights of up to 50 feet have been recorded, according to Wikipedia.Full Answer >
As of August 2014, China has not had any significant tsunamis in over 200 years. Historical records suggest a tsunami in 1782 devastated China, killing 40,000 people. In 1765, an estimated 27-foot wave from another tsunami swept up to 10,000 people out to sea. Storm surges are more common than tsunamis in China. A storm surge occurs when a cyclone creates a single wall of water.Full Answer >
Tsunamis are measured by their runup,which is the difference between an observed sea level and the distance the tsunami waters reach on shore. This is generally measured once the danger has passed, so debris and destruction of plant life are often used as gauges of runup.Full Answer >
