Tsunami warning

According to the US Geological Survey, a severe earthquake that rocked Taiwan’s southeast coast on Sunday caused at least one structure in a tiny village to collapse and prompted Japan to issue a tsunami warning.

The USGS reported that the earthquake struck at 2:44 PM (0644 GMT) at a depth of 10 km, roughly 50 km (30 miles) north of Taitung.

The USGS eventually lowered the earthquake from its initial intensity of 7.2 to 6.9 magnitude. make a situation tsunami in taiwan in red aleart .

The village of Yuli had at least one structure fall, according to Taiwan’s semi-official Central News Agency.

At Dongli station in eastern Taiwan, the Taiwan Railways Administration reported that six cars fell off the tracks when a portion of the platform roof collapsed, although the fire department reported no casualties.

Although there were no reported casualties and rescuers were attempting to restore the roads, the department reported that more than 600 people were stuck by blocked roads on the picturesque Chike and Liushishi mountain districts.

After the earthquake, the U.S. Pacific Tsunami Warning Center issued a warning for Taiwan, but subsequently cancelled the notice. The tsunami warning for a portion of Okinawa prefecture been cancelled by the Japanese meteorological service.

According to imformation

There has been extensive destruction in Taiwan over the past 24 hours as a result of three significant earthquakes. On Sunday, an earthquake with a Richter magnitude of 7.2 shook Taiwan’s Yujing neighbourhood. The passenger train’s carriages also derailed at a station as a result of the earthquake. The earthquake struck Taiwan 85 kilometres east of Yujing. The study states that the earthquake’s epicentre was located at 23.100 degrees north latitude and 121.300 degrees east longitude. At 10.0 km, the earthquake’s depth was being measure According to information from the Central Weather Bureau, a 6.4-magnitude earthquake occurred last night at 9:41 p.m. local time in the county of Taitung in southeast Taiwan (CWB). According to the Bureau of Seismology Center, the earthquake’s epicentre was 7.3 kilometres beneath the surface, 35.8 kilometres north of Taitung County Hall.

The epicentre of the earthquake, according to Taiwan’s Central Meteorological Bureau, was only seven kilometres below the earth’s surface, close to the city of Chishang. According to Taiwan’s Central News Agency, a three-story structure with seven to eleven stores on the ground floor and residences on the top floor collapsed as a result of the earthquake close to the city of Yuli. One person has reportedly been extracted from the rubble, and (relief and rescue) workers are in contact with the three other stranded individuals.

What is main Causes Tsunami ?

As a result of the numerous massive earthquakes linked to subduction zones along the edges of the Pacific Ocean basin, sometimes known as the “Ring of Fire,” tsunamis occur most frequently in the Pacific Ocean. Earthquakes happen 90% of the time along the Ring of Fire. Off Chile, Alaska, Japan, and Indonesia, for instance, there are subduction zones with accompanying deep-sea trenches that have triggered powerful earthquakes and deadly tsunamis, many of which inflicted destruction and casualties in the Hawaiian Islands.

1 . Earthquakes

Movements along fault zones connected to plate boundaries may cause it to occur. A plate boundary is the area where two plates meet, and the type of border depends on how one plate travels in relation to the other:

  1. Two plates spreading apart from one another .
  2. The process of subduction, in which two plates approach one another and one slides beneath the other .
  3. Transform where two plates slide horizontally past each other.

The majority of powerful earthquakes take place in subduction zones, when an ocean plate slips beneath a continental plate or another ocean plate that is younger. Not all earthquakes result in tsunamis. There are four requirements for an earthquake to result in a tsunami.

  • The debris must either slide into the water during the earthquake or occur beneath the ocean.
  • The earthquake must cause vertical movement of the seafloor
  • The earthquake must cause a surface rupture and take place at a short depth—less than 70 kilometers—below the Earth’s surface.

2 . Landslides

A landslide that happens near the shore might push a lot of water into the water, upset it, and cause a tsunami. When the material that has been released by the landslide travels violently and pushes the water in front of it, underwater landslides can also cause tsunamis.

A tsunami can be produced by underwater landslides, which frequently take place following a strong earthquake. Sediment sliding over the sea floor changes the equilibrium sea level during a submarine landslide. Given the initial disruption of the water level, gravitational forces then spread the tsunami. Similar to a land-based volcanic eruption, a severe marine eruption can produce an impulsive force that shifts the water column and causes a tsunami. Landslides that occur over water and space-borne debris might affect the water’s surface. A tsunami is created when the water is moved out of its balance and the falling debris. In contrast to certain earthquake-related ocean-wide tsunamis, tsunamis produced by non-seismic causes typically dissipate fast and seldom strike beaches far from the originating region.
