Explained simply
Asahi is a city in Chiba Prefecture, east of Tokyo, on Japan’s Pacific coast. Japan lies where several of the Earth’s tectonic plates meet, making earthquakes a regular hazard.
Earthquakes can cause damage and disruption beyond the area closest to their source, depending on their depth and how strongly the ground shakes. Tsunami risk depends on factors such as the quake’s location and movement of the seafloor; official agencies assess this separately.
