The last time Tokyo was hit by a big earthquake was in 1923, which had a 7.9 magnitude.
The March 2011 earthquake that hit off the coast of Sendai was magnitude 9.0 and it triggered a massive tsunami.
Researchers at the University of Tokyo's earthquake research institute said "there was a 75% probability that a magnitude seven quake would strike the region in the next four years" as reported in BBC News.
an earthquake kills about 1000 people
It is because, the earthquake that broke of the coast of sendai happened under the sea and the type of the earthquake was a destructive.Meaning it moved the plates backwards and forwards under the sea bed causing the sea above it to violently move back and forwards creating dangerousley high and powerful waves(4-10M) to reach the coast of sendai and sweep miles through the inland areas.
The epicenter of the tsunami that hit Japan on March 11, 2011 is the epicenter of the magnitude 9.0 earthquake that triggered the tsunami.The epicenter for the earthquake was reported by U.S. Geological Survey (USGS) and others to be 129 kilometers (80 miles) off the east coast of the Oshika Peninsula, Tōhoku, near Sendai at a depth of 32 kilometers (20 miles).A global spread of the tsunami can be seen in a related question.
The earthquake in Tokyo occured because, Tokyo lies on three tectonic plates. When those plates come together, seperate, or slide past each other an earthquake happens. However, Tokyo is also a city in a major fault zone!

Cities along the Pacific coast of Japan were most affected by the tsunami that followed the 2011 Tōhoku earthquake. Some of the most severely impacted cities included Sendai, Ishinomaki, and Kamaishi.
