The strange effects of Japanese earthquakes

Seven of the most bizarre effects of the Japanese earthquake and tsunami were reported by OurAmazingPlanet and Live Science .

Japan's terrifying earthquake, followed by a tsunami on March 11, 2011 caused effects on both the globe, from the surface to the atmosphere, changing the gravitational pull of the fruit. land.

OurAmazingPlanet and Live Science have reviewed 7 most bizarre effects of these 2 events.

7. Cracks in the sea floor

The earthquake was to crack the seabed off Tohoku. Submarines have measured cracks from 1 to 3 meters several months after the earthquake.

ten meters at a depth of more than 3,000 meters on August 10, 2011.

6. Smaller earthquakes appear on a large scale

The earthquake occurred in large areas of Japan and created aftershocks. However, scientists believe that aftershocks are not limited to nearby areas.

There is evidence that this earthquake has created smaller earthquakes around the globe, especially where seismic activity is common such as Taiwan, Alaska or central California, with a intensity of no more than 3 degrees. richter. Some earthquakes also occur in areas with little seismic activity such as central Nebraska, Arkansas or near Beijing and even Cuba.

5. The Southern glacier flows faster

GPS reception stations have detected an increase in the flow rate of the Antarctic glacier. Thousands of miles away from Japan, seismic waves of the Tohoku earthquake seem to be increasing the speed of the Whillans glacier temporarily. These glaciers will normally flow slowly from the continent to the ocean.

4. The Antarctic iceberg broke

Earthquakes and tsunamis were so strong and far reaching that they broke giant icebergs in the Sulzberger iceberg in Antarctica. This is an ice mountain range located in the glacier in the sea. Images from satellites recorded this 18 hours after the earthquake.

3. Disturbed atmosphere

Researchers also point out that movements on the surface of the earth and tsunamis caused by earthquakes often produce waves in the atmosphere. In particular, the earthquake in Japan created a disturbance of charged particles at high altitudes, nearly 350 km from the earth.

2. Gravity changes

Grace has found the earthquake so strong that it changes the gravitational pull in the affected areas. It also made the earth's crust thin even though insignificant and an attractive drop in the earthquake area.

1. The day on earth is short

A study conducted a few days after the earthquake showed that it increased the speed of the Earth's rotation, the 24-hour length of a day reduced to 1.8 microseconds. A microphone is 1 millionth of a second.

Richard Gross, of NASA's rocket rocket lab in Pasadena, California, who carried out the measurement, said our increased planetary rotation due to the earthquake changed the mass distribution of the earth. .
