Live seismic activity in Japan — updated every 60 seconds from USGS data. Japan is one of the most earthquake‑prone countries, sitting at the junction of four tectonic plates.
Japan is one of the most earthquake‑prone countries, sitting at the junction of four tectonic plates. Japan experiences about 1,500 felt earthquakes per year – more than any other country. Major faults include Japan Trench, Nankai Trough, Itoigawa-Shizuoka Tectonic Line. Notable quakes include 2011 Tōhoku (M9.1), 1995 Kobe (M6.9). The seismic risk is extreme. Tectonically, Japan lies on pacific plate subducting beneath okhotsk plate. This page provides real‑time USGS data and historical context for Japan.
The region is defined by Japan Trench, Nankai Trough, Itoigawa-Shizuoka Tectonic Line, and the risk level is classified as Extreme. With a population of 125 million, understanding local seismic hazards is crucial.
Japan lies on Pacific Plate subducting beneath Okhotsk Plate. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In some regions, strike‑slip faults produce frequent moderate earthquakes.
The strongest recorded earthquake in Japan was the 2011 Tōhoku earthquake (M9.1). 2011 Tōhoku (M9.1)
Japan experiences approximately 1,500-5,000 earthquakes per year, with 100-500 felt (M3.0+) and 10-20 potentially damaging events (M5.0+) annually, according to USGS historical data.
The most recent major earthquake in Japan was the 2011 Tōhoku earthquake (M9.1). 2011 Tōhoku (M9.1)
Yes. Japan is crossed by Japan Trench, Nankai Trough, Itoigawa-Shizuoka Tectonic Line, making it prone to seismic activity. The seismic risk level is classified as Extreme.
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks. Prepare an emergency kit with water, food, first aid, and a flashlight.
