The 2026 Kumamoto Earthquake May Have Hit a Weak Spot Left by a 2016 Quake

A powerful earthquake (magnitude 7.1) hit Kumamoto, Japan on July 28, 2026, killing at least 13. Kyodo News reports it likely struck a section of underground fracture that a 2016 quake did not fully break. That worries experts: like cracking ice, stress can spread along connected fault lines, possibly triggering more quakes in the coming months.
