The 2007 Noto Peninsula earthquake (能登半島地震) occurred on March 25, 2007, in the Hokuriku region of Japan.
At 9:41:58 a.m. on March 25, 2007, a magnitude 6.9 earthquake struck the Hokuriku region of Japan, near the Noto Peninsula.
Noto Peninsula itself was created by pressure pushing up sediment from the south-east, and many folds and reverse faults are in the area.
[citation needed] This type of earthquake was estimated to have occurred 1~2 times in the last 20,000 years (Frequency).
[3] It also shifted an erosion terrace formed in the ice age and the sediment on top by 10 cm.
According to the National Research Institute for Earth Science and Disaster Prevention, the pattern of the shaking was similar to the shaking in the Great Hanshin earthquake and the 1994 Northridge earthquake, called the "killer pulse": Pulse waves with a frequency of 1–2 seconds.
The shaking then got larger as it reached softer ground like alluvial plains, causing major damage.
[1] The train lines that were stopped after the earthquake were: Noto Airport temporarily closed due to the fact that 22 cracks were found in the runway.
At 11:08, Masanori Tanimoto, the governor of Ishikawa Prefecture summoned 30 soldiers from the Ground forces from bases in Kanazawa, Sabae, Toyama, Kasugai, Nagoya, Hisai, and Takashima.
