The loss of electrical power halted cooling systems, causing heat to build up.  YokosoNews, an Internet webcast in Japan, dedicated its broadcast to the latest news gathered from Japanese news stations, translating them in real time to English.

To prevent under-reporting of tsunami heights, early quantitative observation data that are smaller than the expected amplitude will be overridden and the public will instead be told that the situation is under observation. ", Normally, when two plates collide, there is friction. The 2011 earthquake has been the subject of intense study ever since, and the trench that produced it is the best studied in the world.

Director Hideaki Anno's 2016 film Shin Godzilla portrays the titular kaiju as a representation of disasters such as the Tōhoku earthquake and the Fukushima Daiichi nuclear disaster, and criticizes the Japanese government's response to such disasters. However, these scales "saturate" for earthquakes that are above a certain magnitude (magnitude 8 on the JMA scale); that is, in the case of very large earthquakes, the scales' values change little despite large differences in the earthquakes' energy. Initially, the earthquake caused sinking of part of Honshu's Pacific coast by up to roughly a metre, but after about three years, the coast rose back and kept on rising to exceed its original height. These include Sendai #4, New-Sendai #1 and #2, Haranomachi #1 and #2, Hirono #2 and #4 and Hitachinaka #1.
