‘Ring of Fire’ wriggling… Taiwan, Japan followed by Mexico’s series of earthquakes

Following Taiwan and Japan, a 7.6 magnitude earthquake occurred in Mexico. As earthquakes and volcanic eruptions are active in countries that belong to the Pacific Rim orogeny called the ‘Ring of Fire’, there is growing concern about the possibility of large-scale earthquakes in the future.

According to Reuters and CNN on the 19th (local time), the U.S. Geological Survey (USGS) announced that a magnitude 7.6 earthquake occurred near Demorellos, Michoacan, western Mexico near the Pacific coast at 1:05 p.m. on the same day. The epicenter was relatively shallow at 15 km, so the impact may have been greater, Reuters reported. At 2:30 pm, aftershocks with a magnitude of 5.3 occurred, 76 aftershocks continued for 2 hours after the first earthquake occurred.

In the earthquake, the outer wall of a shopping mall collapsed in Manzanillo, Colima, close to the epicenter, killing one person and damaging a hospital building in Koalco Bay, Michoacan, the epicenter of the earthquake. In some areas in Mexico City, the capital of Mexico, about 475 km away from the epicenter, buildings shook and electricity was cut off.

Mexico’s Federal Electricity Commission (CFE) tweeted: “There have been some blackouts in Mexico City, Colima, Michoacan and Jalisco.” CNN reported that local fire departments had closed some buildings in Mexico City over fears of collapse.

A tsunami warning was issued immediately after the earthquake. The Pacific Tsunami Warning Center said on the same day that a tsunami of up to 3 meters is possible in parts of the Mexican coast. In Colombia, Ecuador, El Salvador, Costa Rica and Peru, tsunamis up to 30 cm high could also occur along the Pacific coast.

Coincidentally, the earthquake in Mexico occurred on the same day as the earthquakes in 1985 and 2017, which caused massive human casualties. In response, the National Autonomous University of Mexico (UNAM) said, “There is no scientific reason that the three earthquakes occurred on the same day.”

Earthquakes have been occurring one after another in countries belonging to the Pacific Rim orogeny, including the earthquake in Mexico that day. In eastern Taiwan, a magnitude 6.4 earthquake occurred on the 17th, followed by a magnitude 6.8 earthquake on the 18th the next day. On the same day, two earthquakes of magnitude 6.1 and 5.5 occurred in the waters west of Okinawa Prefecture, Japan. According to the USGS, 75% of the world’s active volcanoes are concentrated in the Pacific Rim orogeny, and 90% of the world’s earthquakes occur in this region.
