Overview
- USGS recorded a magnitude 6.0 offshore in the Gulf of California on Tuesday, June 30, 2026, with a shallow hypocenter of about 10 km that increases how strongly the quake is felt at the surface.
- The epicenter was located roughly 46–47 miles south‑southwest of El Progreso, Mexico, and EMSC reported the same magnitude and depth, giving analysts confidence in the initial measurements.
- The USGS issued a Green alert for shaking‑related fatalities and economic loss, signaling a low probability of deaths or major damage based on rapid impact models.
- Modelled exposure estimates show about 13,000 people likely felt moderate shaking, roughly 2.6 million felt light shaking, and 334,000 felt weak shaking, and officials reported no tsunami threat and a low chance of liquefaction or major landslides.
- Authorities continue to monitor aftershocks and collect on‑the‑ground reports to confirm damage, with concern focused on communities that use mud‑wall and adobe construction which are more vulnerable to strong shallow shaking.
