This is an interesting earthquake forecast based primarily on solar activity and planetary alignments. The forecast corresponds with the annual Pluto station of April 9 that will concentrate the intensity of this dwarf planet, and the transiting Mars-Pluto square on April 11- mentioned here in recent posts as probable indications of violent upheaval.

Emile Okal: Scientist's Did Not Expect 9.0 Earthquake in Japan,
"The March 11 undersea earthquake off the coast of Japan– which ultimately measured 9.0 on the Richter scale– was a more powerful earthquake than expected for that region, according to geophysicists. That is why the Sendai area of Japan, near the earthquake’s epicenter, was not prepared for such a large quake and the subsequent tsunami. EarthSky’s Beth Lebwohl spoke to Emile Okal of Northwestern University in Evanston, Illinois. He is an expert in large earthquakes and their tsunamis. He said:
Essentially, the feeling was that– if you had a very, very old ocean floor– when it was eventually recycled into the mantle of the Earth, you wouldn’t get these mega-earthquakes.
In other words, although it’s true the March 11 quake happened along the Ring of Fire around the Pacific Ocean, where earthquakes are common, such a large quake had not been anticipated. The March 11 quake happened in a place where Earth’s crust is very old– 140 million years old according to scientists’ reckoning. Old crust is cooler and denser than younger crust. The older crust in this region was believed by geophysicists to dive more smoothly beneath the land plate that carries northern Japan."
