Earthquake Swarm (2019-2020)

Beginning on December 28, 2019, a seismic swarm of more than 11,000 earthquakes struck southwestern Puerto Rico, an unprecedented event that compounded the island's ongoing recovery crisis.

The strongest quake, a magnitude 6.4, struck on January 7, 2020, at 4:24 AM, centered near Guánica. The impact was severe:
- 1 person killed, dozens injured
- Over 2,000 homes destroyed or severely damaged
- 8,000+ people displaced, many sleeping outside for weeks
- Iconic Punta Ventana natural rock arch collapsed
- Schools, churches, and government buildings damaged
- Power outages across the southern coast

The disaster struck a population already traumatized and depleted by Hurricane María. Many of the communities most affected — Guánica, Guayanilla, Yauco, Peñuelas — had not yet fully recovered from the 2017 hurricane. The earthquake damage compounded existing vulnerabilities: homes already weakened by María collapsed, and communities already lacking resources faced a new displacement crisis.

FEMA's response was again criticized as slow. President Trump initially withheld disaster aid, and when it was released, the bureaucratic requirements proved difficult for communities still navigating María recovery. The earthquakes demonstrated that Puerto Rico's colonial status creates a cycle of compounding disasters: each crisis hits a population that has not recovered from the last.
