Are there more earthquakes 2011

In this region, slow slip also happens around the same time as, or just before, a spike in the rate of earthquakes of magnitude 5 and greater. Slow slip may gradually build up stresses along the fault and eventually trigger it to move in the larger quake, Hasegawa says. Because the Tohoku earthquake relieved geological stress, Uchida says, that particular section of the fault is not likely to move in a large earthquake any time soon. But by monitoring slow slip to the north and south of Tohoku, seismologists may get a better idea of how much stress is building there and when a large earthquake is likely to strike again.

Slow slip has happened before other large earthquakes, such as the magnitude In , off the coast of Guerrero, Mexico, a magnitude And slow slip is common along the Pacific Northwest coast, a spot thought to be ripe for a large earthquake in the zone known as Cascadia. For the past five weeks, in a fairly common occurrence, tiny quakes have been marching south from Vancouver Island and into Washington state.

But Japan has a huge advantage over other areas where slow-slip occurs, says Susan Schwartz, a seismologist at the University of California, Santa Cruz. Uchida, N. Science , — Hasegawa, A. Ruiz, S. Download references. You can also search for this author in PubMed Google Scholar.

Ranked on insured losses when occurred. Updated by the Insurance Information Institute using data from Munich Re's Relevant geophysical events worldwide It ranks as the seventh costliest U. Six of the costliest U. No major damage or injuries were reported. It was the strongest quake since an 8. The U. Geological Survey reports that there were aftershocks by August 2. Six of the tremors were magnitude 5 or higher.

It was the strongest quake to hit the area since the November quake see below. On February 27 a quake with a preliminary magnitude of 5. According to the Alaska Earthquake Center, it was an aftershock of the magnitude 7. On January 7, , a 6. The island has not had a quake of this level since The Alaska Peninsula was struck by a 7.
