March 11 is best known for 2011, when a magnitude 9.0 earthquake off northeastern Japan set off a tsunami and a nuclear crisis at Fukushima Daiichi. The date also saw President Franklin Roosevelt approve the Lend-Lease Act in 1941 and the World Health Organization call COVID-19 a pandemic in 2020.
The big story: Japan’s Earthquake, Tsunami and Nuclear Crisis (2011)
At 2:46 p.m. local time, the seafloor along the Japan Trench, roughly 80 miles east of the city of Sendai, gave way. The quake measured 9.0, among the strongest ever recorded, and it was only the start. Within minutes a tsunami as high as about 33 feet pushed over seawalls and ran miles inland, sweeping away towns along the Tohoku coast. Japan’s official tally of dead or missing came to about 18,500, and most of them drowned. Down the coast, the water knocked out the backup generators at the Fukushima Daiichi nuclear plant. Without cooling, the cores of three reactors partly melted, and hydrogen explosions released radiation. Regulators later rated the accident a level 7, the same rating given to Chernobyl. Four years after the disaster, some 230,000 people were still displaced, largely because of the evacuation zone around the plant.
