The 1930 North Izu earthquake (1930年北伊豆地震, Sen-kyūhyaku-sanjū-nen Kita-Izu Jishin) occurred on November 26 at 04:02 local time.

The Izu Peninsula is located in the northern tip of the Philippine Sea plate.

However, the GPS vectors of the Izu Peninsula are almost westwards, which are different from the northwestward motion of the Philippine Sea plate.

The North Izu Fault Zone is about 32 kilometres (20 mi) long, lying in the NNE-SSW direction.
