Earthquake N times!The building collapsed, the bridge was broken ... Why is the earthquake in Taiwan, why is the Hangzhou earthquake so strong?The reason was found →

This afternoon

There are many earthquakes in Taiwan

17:39

A magnitude 5.4 earthquake occurred in Hualien County, Taiwan

16:46

A magnitude 4.9 earthquake occurred in Hualien County, Taiwan

Taiwan Hualien 6.9 Grade Sight Earthquake

The bridge is broken, the train shakes violently ...

Four people trapped by the collapsed building were rescued

Due to the continuous aftershocks,

Many businesses in Yuli Town, Hualien County, Taiwan, have stopped power,

Many motorcycles on the road fall to the ground.

A reporter from the Central Radio and Television Station in Hualien County, Taiwan

Seeing Yuli Town Railway Station,

The train stopped on the orbit

Shake severe.

According to the local public report,

Gao Liao Bridge Bridge Devene in Yuli Town, Hualien

It has been cut into a number.

Gao Liao Bridge, Yuli Town, Hualien

It is an important local traffic bridge,

March 22 this year had a earthquake due to earthquakes

Causes bridge railings, label fences, road surfaces

Wait for the facilities to be damaged,

The road was renovated in June.

The crash of the station's rhizon caused the train to tilt

Affected by MRT operations in many places

The Taiwan Railway said,

The canopy of Hualien Dongli Station was broken,

Press to the No. 4204 train in the station,

There are 20 passengers on the car,

Fortunately, no one was injured.

The Taiwan Railway said,

Send personnel have assisted in handling related events.

Taiwan Kaohsiung MRT was suspended due to the entire earthquake. Kaohsiung MRT stated that the current trains are currently changed to 20 kilometers per hour. The current train will be cleared after the next stop. , Restore normal operation.

The Taichung City MRT stated that the signal system has been confirmed that there is no abnormal alarm, the power system has no escape, and the entire line of trains will slowly enter the station to evacuate passengers. The station review station body and the maintenance unit has been notified.

Taipei MRT pointed out that after receiving the news of the earthquake, it immediately carried out the slow speed tour of the entire train according to the standard process. This was also the second time that the North P. was driving slowly on the same day.

There is a building collapse

4 people have been rescued

A building in Yuli Town, Hualien County collapsed due to the earthquake, and the police and fire departments were searching and rescue.

According to the reporter of the heads at the scene, four people were trapped in the collapsed building in Yuli Town. At present, the four trapped people have been rescued, and the rescue time lasted more than three hours.

Taiwan Hualien 6.9 Earthquake,

Why is there a high -rise building in Hangzhou, but the ground has no feeling?

The reporter learned from the Zhejiang Earthquake Bureau,

This earthquake is located in Hualien County,

About 541 kilometers from Wenzhou City, our province,

It is about 794 kilometers in Hangzhou.

When the earthquake occurs,

Wenzhou, Taizhou, Ningbo, Ningbo,

Hangzhou, Jiaxing, Lishui and other areas

There are shocks.

September 17th

Magnitude 6.5 earthquake in Taitung County, Taiwan

The distance from the earthquake is 14 kilometers.

Just a few issues that everyone cares about,

The Zhejiang Earthquake Administration answered.

01

Why are there many earthquakes in Taiwan?

Taiwan Island is located at the junction of the Eurasian sector and the Pacific sector. It is one of the most intense segments on the Western Pacific Earthquake Bands. In addition to the strong earthquakes, there are deep -source earthquakes in the eastern waters. So far, there are 33 proven activity faults. Earthquakes are frequent, especially in the eastern earthquake activities of Taiwan than western Taiwan. Since the records, nearly 300 magnitude 6 to 6.9 earthquakes occurred in Taiwan and the surrounding waters, with more than 40 magnitude 7-7.9 earthquakes, and magnitude 8 or more earthquakes.

The faults of the eastern part of Taiwan are strong. The breaks are mainly distributed on both sides of the Huadong Ridge Valley and the Ridge Valley. The Handong Ridge Valley is the collision junction of the Eurasian and the Pacific plates. Due to the squeezing each other in the two sections, the earthquake activities are very frequent. A magnitude 6 to 6.9 earthquake occurred more than 200 times, and more than 30 magnitude 7 to 7.9 earthquakes. The magnitude 8 or more occurred in the eastern part of Taiwan.

The fracture of western Taiwan is mainly located in the Taiwan West Plain. The earthquake movement is weaker than in the eastern part of Taiwan. A magnitude 6 to 6.9 earthquake occurred in nearly a hundred times, and a magnitude 7-7.9 earthquake. A magnitude 7.6 earthquake in Jiji Town, Nantou County, Taiwan on September 21, 1999 was an earthquake caused by the Canpu Fracture activity in western Taiwan.

Why is there a high -rise building in Hangzhou, but the ground has no feeling?

This is because the seismic waves generated during the earthquake have passed through long distances, and its high -frequency component (short cycle wave) has gradually decayed. When reaching Hangzhou, the earthquake waves are mainly low -frequency wave (long cycle), and the wavelengths are long. The higher the floor, the more the vibration cycle of the building will be similar to the cycle of these earthquake waves. The resonance phenomenon occurs, and the vibration will be obvious.

In addition, because the foundation foundation in Hangzhou is mainly deep and soft, it has a significant amplification effect on the earthquake waves. As soon as the earthquake, the high -rise building with a self -containing cycle of the vibration cycle is easy to resonate with the long -term earthquake waves that have been softened. Even if the magnitude of the earthquake is small or the epicenter distance is far away, it can cause a strong earthquake reaction of high -rise buildings on the venue. Therefore, the Taiwan earthquake, Hangzhou, 800 kilometers, has a clear sense of earthquake.

But don't worry, high -rise buildings implement strict earthquake resistance standards and have strong earthquake resistance. When earthquakes occur, if you live in high -rise, do not rush to run out. Do not rush to run out. Chandie lights, vases, high cabinets and other pendants, wait for the earthquake to evacuate and evacuate.
