The earthquake occurred as the result of shallow reverse faulting along the Kuril-Kamchatka Trench, and caused Modified Mercalli Intensity (MMI) X (Extreme) shaking, as well as a tsunami 5 m on high. Iturup sustained significant damage as a result of the shaking and tsunami, with other locations along the Kuril Islands also reporting strong damage. Tectonic setting The Kuril Islands lie along the seismically active convergent boundary between the Pacific plate and the Okhotsk plate (a microplate within the North American plate).Bürgmann Kogan Steblov Hilley 2005 The trench that accommodates this subduction—the Kuril-Kamchatka Trench, accommodates the convergence at a rate of 80 mm on/yr, with rates increasing from north to south.Bürgmann Kogan Steblov Hilley 2005 This active subduction zone spawns many large Kamchatka earthquakes with strong earthquakes along the trench occurring in 1737, 1841, February 1923, April 1923, 1952, 1959, and in 1963. Earthquake The earthquake struck at 09:58 on November 7 locally, or 22:58 on the 6th in UTC. The earthquake occurred at a depth of 35–40 km on, with a moment magnitude of w 8.3–8.4. The International Seismological Centre estimated the surface-wave magnitude for this event at s 8.2 ± 0.3. Maximum felt intensities associated with the earthquake were X (Extreme) on the Modified Mercalli intensity scale in Lake Iturup. The earthquake occurred as the result of reverse faulting along the Kuril-Kamchatka trench. Despite having a relatively short aftershock area of 150-170 km on long by 70-80 km on wide, the earthquake had a high stress drop and large felt area. A 1979 study attributes this to an unusually long interval between ruptures, which allowed more stress to build up.Fukao Furumoto 1979Mogi 1968 178 Tsunami The tsunami from this earthquake reportedly reached up to 5 m on in height at Shikotan Island, 2-4 m on at Iturup, and up to 2 m on in northern Hokkaido. Midway and Hawaii also recorded many runups, including a 0.3 m on measurement in Kahului, Maui, and a 0.2 m on runup in Midway. Attu Island, Alaska and Wake Island recorded 0.2 m on tsunami, with Kwajalein, Marshall Islands, Pagopago, Samoa recording 0.1 m on.Iida Cox Pararas-Carayannis 1967 In California, San Francisco recorded 0.2 m on tsunami heights,Lander Lockridge 1989 and Port Hueneme recorded tsunami as well. Tsunami waves reached as far as Talara, Peru.Iida Cox Pararas-Carayannis 1967 A tsunami warning was issued for coastal Hokkaido and portions of Honshu, however the feared tsunami failed to materialize.Rothé 1969 156 A w 7.0 aftershock on November 12 caused another tsunami with runups reaching 1 m on at Iturup and 42 cm on at Hachinohe, Japan. Sweeper Cove in Adak Island recorded a 0.1 m on tsunami, which was larger than that of the main shock's in the same area.Iida Cox Pararas-Carayannis 1967 Damage Lake Iturup sustained the greatest damage, with many older buildings ruined, moved furniture, and cracks in the cement basins of fisheries. Lake Kunashir also suffered severe damage, with reports of appliances and buildings being destroyed. Various physical changes occurred in the Kuril Islands such as "agitated" bodies of water, changes in the level of ground-water, landslides, earth creeps, creation and destruction of hot springs, and new fissures forming.Kondorskaya Shebalin Khrometskaya 1982 533 Kushiro sustained lesser damage including cut telephone lines and halted trains.Rothé 1969 156 Miyako in Iwate suffered some damage to its oyster bed.
