On September 19, the Mw7.1 “Puebla” earthquake struck Mexico City and surrounding states, causing the most fatalities (369) and damage of any temblor since the Michoacán event in 1985. The Mexican government has not yet published overall economic or insured loss tallies, but six days after the earthquake RMS publicly released an estimate of economic property losses between US$4 billion to US$8 billion and no more than US$1.2 billion in insured property losses.
To better understand the impact of this event, RMS sent a reconnaissance team to the affected region from October 1 to October 6. The RMS team spent most of the trip surveying sites in Mexico City but also visited Cuernavaca, Puebla de Zaragoza, and other cities in the states of Morelos and Puebla that were closer to the epicenter than the capital (Figure 1). This blog shares some of the key observations made by the RMS team.
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.
