On the morning of Tuesday, September 19, people across Mexico had taken part in the annual national earthquake drill and other remembrance activities, to commemorate 32 years since the 1985 Mw8.0 Michoacán Earthquake. Michoacán was the most devastating earthquake in Mexico’s history, leaving at least 9,500 people dead and more than 100,000 homeless.
No one could have imagined at the time of these drills that a little more than two hours later, at precisely 1:14 pm local time (CDT), they’d be experiencing a real earthquake, the same day as Michoacán, as the Mw7.1 “Puebla” earthquake struck Mexico City and surrounding states. The improbable had become reality.
RMS estimates that the Puebla earthquake caused between US$4 billion and US$8 billion in economic property losses and as much as US$1.2 billion in insured property losses. This estimate accounts for shake-only losses to building, contents and business interruption, including the effects of liquefaction and landslides.
