At 9:42 a.m. on March 25, 2007, the Noto Peninsula Earthquake (能登半島地震 Noto hantō jishin), a magnitude 6.9 earthquake, struck the Hokuriku region of Japan, near the Noto Peninsula. The earthquake shook the city of Nanao and the town of Anamizu with a seismic intensity of 6+ on Japan's shindo scale. One death, in the city of Wajima, and at least 214 injuries have been reported. A tsunami advisory was immediately made for the Kaga coast and Noto coast, and a 10-20 cm wave hit shore about 30 minutes later. [1]
The Japan Meteorological Agency placed the earthquake at 37.3°N, 136.5°E, at a depth of 50 km. It estimated the magnitude at 7.1, but later revised its estimate to 6.9. The earthquake had a maximum three-component vector sum peak ground acceleration of 1,304 cm/s2 (1.33 g).[2]
