PURPOSE
The purpose of this page is to provide GEM website visitors, researchers, loss modellers, and emergency and disaster risk reduction professionals with specific downloadable information related to red alert events based on USGS PAGER alerts. GEM promotes the sharing of seismic hazard and risk information with a wide range of stakeholders to enhance understanding of damaging earthquake events. This initiative aims not only to give an overview of the models, data and publications available in areas recently impacted by earthquakes, but also hopes to serve as a resource that can inform future risk reduction strategies. The information provided is intended solely for situational awareness purposes and is not aimed towards driving an official emergency response. Please contact your local authorities for further assistance related to official emergency response services and support.
28th July 2026 M6.8 Japan
On 28 July 2026 at 16:27:15 JST (07:27:15 UTC), an earthquake struck Kumamoto Prefecture in southern Japan with a magnitude of Mw 6.8 at a depth of 10 km. The earthquake was caused by strike‑slip faulting. The USGS focal mechanism solution suggests coseismic slip occurred on either on a northwest-trending left‑lateral fault or northeast-trending right‑lateral fault.
