Mexico suffered a 7.7-magnitude earthquake on September 19, local time, and another 6.7-magnitude aftershock three days later. After an earthquake, cities may suffer from water and power outages, medical malfunctions, network outages and other associated failures. In terms of climate, tsunamis may strike and cause floods. Post-earthquake disaster prevention work needs to be completed based on these aspects. After the exercise, a real earthquake struck

At around 13:00 local time on September 19, Mexico City, a sharp earthquake warning siren sounded in Mexico City. ?

Coincidentally, at this time, the entire Mexico has just concluded the 2022 earthquake warning drill not long ago. Some citizens even stayed in shelters and did not return home.

The earthquake was measured as magnitude 7.7 by relevant departments in Mexico. The center of the earthquake was in Michoacán, Mexico, with a depth of about 15 kilometers.

According to a report from the Mexican Civil Defense, one person was hit by a falling wall member in a shopping mall in Colima state, which was close to the epicenter of the earthquake, and unfortunately died. In addition to this, there was some building damage.

At 1 o'clock in the morning two days later, Mexico suffered the largest aftershock of more than a thousand, with an intensity of 6.7 and a focal depth of 20 kilometers. The aftershock caused 1 A female resident died.

In addition, the Chinese Embassy in Mexico has reported that there is currently no news of Chinese citizens being injured or killed in the earthquake. Known as the Curse of 9.19

In addition to causing loss of life and property, this earthquake also widely triggered social concerns about the date of 9.19.

When the first wave of earthquakes struck, Mexico was conducting earthquake drills. This exercise is not only to improve the whole society's ability to avoid earthquakes, but also to commemorate the two major earthquakes that Mexico has suffered.

On September 19, 1985, an 8.1-magnitude earthquake struck Mexico. 30% of the buildings in the capital were destroyed and more than 10,000 people were injured.

On September 19, 2017, another 7.1-magnitude earthquake occurred in central Mexico, killing more than 300 people.

Fortunately among misfortunes, the epicenter of this earthquake was sparsely populated, so the damage caused was much smaller than the previous two.

However, the panic and speculation caused by this are rampant in the society. Some Mexican citizens say this is a "curse" because the three consecutive major earthquakes that hit Mexico all occurred on September 19th in different years. .

Physics experts from the National Autonomous University of Mexico also admitted that the chance of such a coincidence occurring is less than one in 100,000. Preventive measures after the earthquake

Currently, Mexico is closely monitoring the normal operation of supporting businesses such as power supply and network services to avoid causing collateral disasters.

In addition, the city of Coalcoman in Michoacán, located in the epicenter, has announced that the city’s water and electricity network and other related services are basically normal.

In response to the weather on the Mexican coast, the U.S. Tsunami Warning Center issued a warning of a tsunami caused by an earthquake. The tide level of the waves will reach more than 1 to 3 meters.

A number of towns along the Mexican coast have been affected. Flood disasters caused by tsunamis have already occurred in some places, and local residents had to use boats to travel and avoid danger.

According to the Mexican National Meteorological Center, the Popocatepetl volcano southeast of Mexico City and another volcano in Colima state also showed signs of activity.

Disaster prevention measures after earthquakes include many aspects, such as aftershock monitoring, resident evacuation, building reinforcement, disease prevention and control, tsunami and flood prevention, etc.

When the aftershock activity becomes relatively stable, urban cleanup and reconstruction work will need to begin.

Before that, Mexico may need to first stabilize people's hearts and avoid the idea that "9.19 is an ominous omen" from taking hold.
