• Authorities in El Salvador and Guatemala reported no damage, no casualties, and no tsunami warning after the offshore quake near Barra de Santiago.
• SASMEX did not activate sirens because the shaking in Mexico fell below its distance-and-magnitude criteria for Mexico City alerts.
• The SSN logged 26 overnight earthquakes on August 22 within Mexico, the strongest at magnitude 4.1 in Oaxaca and Chiapas, also without alerts or reported impacts.
• Year to date through the morning of August 22, Mexico has recorded 21,824 earthquakes, most between magnitudes 3.0 and 3.9, consistent with the country’s tectonic setting monitored by SSN-UNAM.
