A shallow magnitude 4.4 earthquake was reported after midnight near Mayaguez, Mayagüez Barrio-Pueblo, Mayagüez, Puerto Rico.
According to the United States Geological Survey, the quake hit on Sunday 18 July 2021 at 12:45 am local time at a shallow depth of 16.9 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.4 earthquake as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in La Parguera (pop. 1,100) located 12 km from the epicenter, Lajas (pop. 5,300) 19 km away, Cabo Rojo (pop. 10,800) 22 km away, San German (pop. 12,100) 22 km away, Guanica (pop. 9,200) 24 km away, Sabana Grande (pop. 9,000) 26 km away, Hormigueros (pop. 11,900) 28 km away, and Mayaguez (pop. 78,600) 34 km away.

Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Aibonito (pop. 8,900) located 94 km from the epicenter, and Guayama (pop. 21,600) 107 km away.
