Overview
- The SSN logged multiple moderate events on Wednesday, Aug. 5, including a M4.5 at 00:13 near Ciudad Hidalgo, Chiapas, and continued to record similar M≈4 shocks into the night and early Thursday, Aug. 6.
- Notable later events included a M4.0 off Santa Rosalía (20:43 Aug. 5), a shallow M4.4 south of Zihuatanejo (22:37 Aug. 5, depth 5 km) and a M4.0 southeast of Lázaro Cárdenas (01:35 Aug. 6, depth 3 km).
- Authorities report no confirmed widespread damage or casualties from these quakes and say Protección Civil teams have performed routine inspections in affected coastal and nearby communities.
- The activity is attributed to Mexico’s complex plate interactions—chiefly the Cocos and North American plates—and the SSN is issuing near‑real‑time lists plus morning and evening reports to inform officials and researchers.
- Because some events occurred at shallow depth and Mexico City can amplify distant shaking, officials urge residents to follow preparedness steps, check buildings after tremors, and rely on SSN and Protección Civil for confirmed updates.
