The 1994 Kuril Islands earthquake – also known as the Hokkaido Toho-oki earthquake – occurred on October 5 at 00:23:00 local time October 4 at 13:23:00 UTC. The magnitude of this earthquake was put at w y8.3, or jma 8.1 y. The epicenter was located at about 70 km east of Shikotan Island. The shaking and tsunami caused road and building damage. At least 10 people were reported dead.

Damage
Oil storage tanks in Malokurilsk and Krabozavodsk were damaged.

Aftershocks
A large aftershock of magnitude w y 7.1 or s y 7.7 occurred on October 9, 1994, at 07:55 UTC. It was located at 43.97° N, 148.22° E with a depth of 33 km. It generated a tsunami, and a peak-to-trough tsunami wave height of 18 cm was recorded in Hanasaki, Japan.
Tsunami
A numerical simulation of the tsunami suggested that the first wave was caused by a significant subsidence north of the Kuril Islands due to the earthquake."Generation of Tsunamis in the Okhotsk Sea Caused by the 1994 Great Kuril Earthquake" by Y. Tanioka
