Slideshow: America's Ten Riskiest Nuclear Reactors

The Nuclear Regulatory Commissions calculated the odds of an earthquake damaging the core of every reactor in the country. Here are the ten riskiest.

The odds listed were generated by the Nuclear Regulatory Commission, and reflect the chances of an earthquake causing damage to each reactor's core. The odds take into consideration two main factors: the chance of a serious quake, and the strength of design of the plant. They also factor the changes in USGS data from 1989 to 2008.

Cascadia: The West Coast Fault Line That Is "Nine Months Pregnant"

The fault zone that produced the largest known earthquake in the Lower 48 is "nine months pregnant and overdue." This time line illustrates it.

Ever since the massive 9.0 magnitude earthquake struck Japan, I've been thinking a lot about my friends in Oregon. Why? Because the impending "Big One" that Californians are nervous about is actually a lot more likely to occur off the coast of Oregon—and would be an even "Bigger One" there.

Interactive Map: The Real Seismic Threat to Our Nation's Nuclear Power Plants

This great interactive map from Climate Central lets you see the specific seismic threat to all 104 of the country's active nuclear reactors.

After we heard that local utilities in Virginia were shutting down the local nuclear power plant in the wake of the earthquake that shook the East Coast today, we pulled this map from our archives to see which other plants might be in harm's way. —The Editors, August 23, 2011

Last week, we posted a link to a map mashup of nuclear reactor sites and the USGS-described "seismic hazard zones" in the United States. Climate Central dug a little deeper into the data, and created a really interesting interactive map that further explores the earthquake risk to America's nuclear power plants.
