From yesterday evening to this morning, there were more than 200 earthquakes in less than a day, including many extremely shallow earthquakes, with the shallowest depth being only 1.1 kilometers.centralMeteorological AdministrationWu Jianfu, director of the Earthquake Forecasting and Forecasting Center, said that many aftershocks in recent days are extremely shallow earthquakes. In addition to being related to geological structures, the reason may also be errors in rapid reporting results.

According to statistics from the Meteorological Administration, from yesterday evening to today, there have been 7 earthquakes with a depth of 2 kilometers (including 2 kilometers). At 7:16 yesterday evening, there was a magnitude 3.6 earthquake with a depth of only 1.1 kilometers; at 2:56 this morning An earthquake with a magnitude of 3.6 and a magnitude 3.4 earthquake at 2:59 a.m. both had a depth of only 1.4 kilometers; a magnitude 5.8 earthquake at 8:04 this morning had a depth of only 2 kilometers.

Wu Jianfu said that a series of large earthquakes occurred one after another at 5 o’clock yesterday evening. They were all located south of the epicenter of the Hualien earthquake on April 3. They were also judged to be aftershock sequences. Because the energy in the north was released, the stress was adjusted to start releasing in the south.

Then at 2:32, another earthquake with a magnitude of 6.3 occurred, with a depth of only 5.5 kilometers. The shallower the depth, the more obvious the people’s feelings. .

Regarding the successive extremely shallow earthquakes, Wu Jianfu pointed out that it may be due to special geological structures that lead to shallower depths, or there may be errors in the quick report results.
