The tsunami that struck Japan’s Tohoku region in 2011 was touched off by a submarine earthquake far more massive than anything geologists had expected in that zone. More than 15,500 people died. Most tsunamis, like the one that formed off Tohoku, are triggered by underwater tectonic activity, such as earthquakes and volcanic eruptions. The Fukushima Daiichi Nuclear Power Plant cooling system was damaged, raising fears of a meltdown. © Stay up to date on the coronavirus outbreak by signing up to our newsletter today. forced removal of something, often people or organisms, from their communities or original space. Becky Oskin - Contributing Writer Scientists drilled into the subduction zone soon after the earthquake and discovered a thin, slippery clay layer lining the fault. The tsunami waves reached run-up heights (how far the wave surges inland above sea level) of up to 128 feet (39 meters) at Miyako city and traveled inland as far as 6 miles (10 km) in Sendai. Its full distance was opened 49 days after the quake, on April 29 – a quick recovery for the shinkansen compared to 81 days after the Great Hanshin-Awaji Earthquake in 1995 and 66 days after the Niigata-Chuetsu Earthquake.
