A tsunami advisory came and went within hours, but a shopping mall collapse in nearby Kashima Town has left rescue crews digging through the night. A magnitude-6.1 aftershock followed about 40 minutes later, one of dozens that have continued through the night. An Evacuation Order Nobody Can Quite Pin DownSeven Kyushu prefectures — Kumamoto, Nagasaki, Kagoshima, Fukuoka, Saga, Oita, and Miyazaki — received emergency alerts telling residents to seek shelter. Japan's Meteorological Agency canceled that advisory roughly two hours later, once it became clear no destructive wave had materialized. Something similar came up in 2016, when a major earthquake struck this same corner of Kyushu just days ahead of a powerful quake in Ecuador.
