Global seismic activity is weak in 2019 for first time in six years without exceeding 8.0 magnitude

According to the data summary of China Seismological Network, there were 115 earthquakes of magnitude 6.0 and above in 2019, of which only 9 were earthquakes of magnitude 7.0 and above, with a maximum of 7.8 magnitude, and none of them reached or exceeded 8.0 on May 26 in northern Peru. China Seismological Network pointed out that in 2019 the global 7.0 magnitude and above earthquake frequency is small, low intensity, breaking the global 2004-2018 every year there are 8 or more earthquakes occurred in the strong state of activity.

Earthquakes of magnitude 7.0 and above are concentrated in the Pacific Rim seismic belt, especially in Southeast Asia, eastern Australia and eastern Latin America, but they are far from China.

There were five earthquakes of magnitude 6.0 and above in China and the surrounding waters, the largest of which occurred on April 18 in the waters of Hualien County, Taiwan, with a magnitude of 6.7.

The largest earthquake in the Mainland occurred on April 24 in Mote County, Linzhi City, Tibet, with a magnitude of 6.3, and a 6.0-magnitude earthquake struck the mayor of Ning County, Yibin, Sichuan Province, on June 17, compared with about 150 earthquakes in Sichuan province last year.

Industry insiders say that the global average of the past 30 years 6.0 or more earthquakes close to 150, 7.0 magnitude or more earthquakes 18 or so, and last year the overall global strong earthquake activity is weak, and 7.0 magnitude or more earthquake epicenters are located in the subduction zone in the back section, as a multi-seismic depth of the deep medium-deep source earthquake.
