Japan has the risk of picking up earthquakes of 8 Richter scale

According to the seismological experts, Japan has the risk of suffering more earthquakes of magnitude 8 in the future.

In the day of disaster 11/3, Northeastern Japan suffered 3 earthquakes with the first 9-magnitude strong battle and 7.7-degree aftershock after 30 minutes and two 7-Richter matches scattered throughout the day.

As of 11:32 pm on April 7, the area shook with the fourth earthquake with a magnitude of 7.4 on the Richter scale.

A warehouse in Kurihara City, Miyagi Prefecture, collapsed after the quake
land of 7.4 degrees Richter on 7/4.

This is the latest statistics of the Japan Meteorological Agency and is also a rare phenomenon so far about the level of occurrence with the dense frequency of the seismic "gods" level 7 in this island nation. .

Often aftershocks have a smaller intensity and widening distance, but yesterday's aftershocks are considered a rare case in seismology.

The Meteorological Agency also said that the most common aftershock after a month with only 1 Richter difference, the possibility of aftershocks of magnitude 8 in Richter scale is entirely possible in the coming time.

Professor Furumura Takashi of Tokyo University of Seismic Research said: ' The number of earthquakes with magnitude of 9 on Richter scale is very small, so it is very difficult to determine the risk of earthquakes in the future. For months even 1 year after the last East Japan earthquake, the risk of aftershocks of 8 Richter levels is also very high. '

Earlier, the Japan Meteorological Agency also warned of aftershocks from level 5 and above. The aftershock on 7/3 was thought to have only arisen for the first time in 37 years. Many seismic experts all agree that 'the earthquake off Miyagi Prefecture is rare. '

Professor Takeshi Sageya of Nagoya University's Seismology Department emphasized: 'The stratum occurred on the coast of Miyagi still cracks after the March 11 earthquake and requires frequent earthquake warnings from now on. '.
