The shock had a maximum intensity of VII (Very strong) on the Mercalli scale. The earthquake was initially reported as a 7.3 magnitude by Japan Meteorological Agency, and was later revised to 7.4, while the United States Geological Survey and GFZ Potsdam determined a magnitude of 6.9. There were no deaths as a result of the earthquake, however seventeen people were injured; three of which were in critical condition.Ozaki A. Morita T. Nishikawa Y. Leppold C. Sawano T.

The Fukushima Daini Nuclear Power Plant had one of its spent fuel cooling systems shut down briefly, though no measurable change in radiation levels was detected. A tsunami warning was issued with waves predicted up to 3 m ftin, though actual waves were recorded between 1 m ftin and 2 m ftin in height. Earthquake The earthquake measured magnitude 7.4.

The 2011 and 2016 earthquake did not occur on the same fault with the later of the two taking place on a different fault of shallower depth. The mainshock of 2011 was followed by a series of aftershocks off Japan's eastern coast most of which didn't crest over a 5.0 in magnitude; being felt mainly along the Fukushima coastline.

The list of prefectures that were first warned includes Aomori Prefecture Pacific Coast, Iwate Prefecture, Miyagi Prefecture, Ibaraki Prefecture, Chiba Prefecture.Japan earthquake and tsunami of 2011 https://www.britannica.com/event/Japan-earthquake-and-tsunami-of-2011 2021-12-02 Encyclopædia Britannica Another warning was issued at 7:26 JST and more prefectures were included in this warning. Two more tsunami announcements were made at 8:09 and 9:46 and then all tsunami warnings were released for all forecast zones at 12:50. Some of the forecasted wave heights were surpassed by those observed and the reverse also happened. It was forecast for both Central Hokkaido Pacific Coast and Western part of the Pacific coast of Hokkaido that they would only see slight sea level fluctuations, however they witnessed a maximum wave of 32 and 23 cm respectively. Most of the other maximum wave heights recorded did not reach the forecast height for their zones, notably the Miyagi and Fukushima Prefecture had a forecast of 3m when they reached 144 and 83 cm respectively. Because the earthquake was generated via a shallow rupture of a normal fault the resulting tsunamis were confusing to experts, as a M 7.4 earthquake would normally only cause minor displacement to the seafloor and not be a tsunami hazard. The research team of Observational Seismology led by Wei Shengji surmised that a submarine landslide occurrence along a slope caused by the earthquake could cause higher tsunami waves produced in local regions. Impact Shaking was felt as far North as Misawa, Aomori Prefecture (approx. 366 km away from the epicenter of the earthquake) and as far south as Kobe (approx. 637 km away from the epicenter of the earthquake) according to crowd-sourced data compiled by the USGS.M 6.9 – 35 km ESE of Namie, Japan https://earthquake.usgs.gov/earthquakes/eventpage/us10007b88/dyfi/intensity live 2021-10-11 United States Geological Survey https://web.archive.org/web/20211011044253/https://earthquake.usgs.gov/earthquakes/eventpage/us10007b88/dyfi/intensity October 11, 2021 Seventeen people were injured during the earthquake, including broken bones and cuts from falling objects, three of which were serious injurieshttp://www.asahi.com/articles/ASJCQ5V91JCQUTIL06R.html 福島沖地震、５１万人に避難指示・勧告 １４人が負傷 Fukushima ocean earthquake, 510,000 people advised to evacuate, 14 people injured ja November 22, 2016 November 24, 2016 November 25, 2016 https://web.archive.org/web/20161125174258/http://www.asahi.com/articles/ASJCQ5V91JCQUTIL06R.html dead while only minor property damage was recorded.https://weather.com/news/news/japan-earthquake-fukushima-tsunami-warning Strong Japan Earthquake Produces Tsunami but Spares Major Damage Breslin Sean The Weather Channel November 22, 2016 November 23, 2016 There was a fire at a research facility in Iwakihttp://fortune.com/2016/11/21/japan-earthquake-tsunami-fukushima/ Tsunami Hits Off Japan's Fukushima Coast After Powerful Earthquake November 21, 2016 Fortune.com November 23, 2016 https://web.archive.org/web/20161125085603/http://fortune.com/2016/11/21/japan-earthquake-tsunami-fukushima/ November 25, 2016 dead as well as a brief power outage was reported for about 1,900 houses. Finally, local and express trains, including the Shinkansen, were out of service for time to allow for the tracks to be inspected.
