After the M6.3 earthquake in the Philippines there has been no response in regions such as Northern New Zealand, Fiji, Tonga, Indonesia, Japan or the Philippines. At least one M6.5 and in the worst case M7+ event will be recorded in these areas

... Earthquakes originating on the coast have reached scales of up to 8.2, but with few aftereffects in the Metropolitan Zone. It has been the earthquakes generated in the geological faults of the Santiago River and in the area of Jocotepec that have generated the most devastating tremors for the city, some of up to 7.5 as the one that occurred in 1875 and destroyed San Cristobal de la Barranca and part of Zapopan.
On December 15, 2015, a process of activity began on this fault, which was reduced in March 2017. Even, the tremor recorded on May 11, 2016, of 4.8 degrees of intensity, was part of this cycle known as swarm. Activity resumed briefly between 2020 and 2021.
Pretty much where there had been a lot of building construction through the years.No plans for a short distance earthquake
Only Zapopan has developed a real estimation of the real impact in case of an earthquake generated in the Santiago River fault. The study was conducted by the Japanese specialist Kit Miyamoto and it indicates that the zone of greatest impact in the event of an earthquake on the Santiago River fault would be from the area of Puerta de Hierro to the Constitución neighborhood, passing through the center of Zapopan.
In the most catastrophic scenario, with a 7.7 earthquake, it is estimated that 29% of the buildings would be critically damaged and 31% would be severely damaged. The estimated death toll would be 2,100 and 17,000 injured. This does not include damage in other metropolitan municipalities.
