The people living on the northeast coast of Japan had learned to expect large earthquakes. But despite being one of the best-prepared nations, they were caught off-guard by the force of the March 11, 2011, earthquake and tsunami that devastated their coastline and led to the meltdown of reactors at the Fukushima nuclear power plant.
Many areas of the world are far less prepared, and the effects of major earthquakes, hurricanes and floods can be even more far-reaching than they have been in Japan. But there are measures we can take to lessen the impacts of such events. A worldwide effort is underway to improve resilience against the forces of nature, and to link that effort to sustainable economic development.

The Great Japan Earthquake: Where Did Scientists Go Wrong? from Earth Institute on Vimeo.
In the two and a half weeks since a massive earthquake struck Japan, scientists from the Lamont-Doherty Earth Observatory have been immersed in both studying the quake, and reaching out to the media and other organizations to explain what happened. Other Earth Institute experts have added their voices to the public conversation about natural hazards, preparedness and nuclear power.
Can we ever be prepared enough for such events? The Japanese were as experienced as any people on the planet when it comes to dealing with earthquakes. Yet they were caught off-guard by a once-in-a-thousand-year event. In a matter of hours, that same event washed ashore on the U.S. West Coast, a relatively minor reminder that we, too, may not always be ready when the power of natural forces takes charge.
The jolt in Japan stunned even scientists who’ve studied earthquakes all their lives. Chris Scholz, a Lamont-Doherty Earth Observatory professor with decades of experience looking at how earthquakes work, said he had thought a 9.0 magnitude quake like the one that struck near Sendai, Japan, was “impossible” in that area (see video). But it turns out the last comparable earthquake shook the same region in the year 869 and pushed a tsunami miles into the interior. Scientists were humbled by the realization that they simply had not looked back far enough to gauge the probability of such a huge event.
