Let’s get right to the point: What happens the next time a nuclear reactor goes rogue in the wake of a natural disaster? Japan is a worst case scenario in a best case place.

But what if the earth were to quake in Iran, China, Italy or Turkey—all of which are pursuing nuclear-fueled futures? Or Pakistan, where the IEAE  and US just gave their respective stamps of approval for two new Chinese-built plants? Each of those seismically-rocking countries floats precariously at (tectonic) plates’ edge. In fact, one of two reactors planned for Turkey is just a few miles from a major fault line.

The assurances of political leaders such as Iran’s Mahmoud Ahmadinejad are somehow less than reassuring: “I don’t think there will be any serious problem…The security standards there are the standards of today. We have to take into account that the Japanese nuclear plants were built 40 years ago with the standards of yesterday.”

Forty years may seem like an eternity to a politician, but is, in fact, a blink in a time-scale defined by nuclear radiation (see Chernobyl). Inspections have a way of getting missed (see Japan). Human error happens (see Three Mile Island).

In the meantime, major earthquakes striking all of these countries sometime over the projected lifespans of their reactors is a sure thing.

The March 11 earthquake off the east coast of Japan was one for the record books. Now rated a 9.0 on the Richter scale by the Japanese Meteorological Society, up from what was still a rather gobsmacking 8.9 initial estimate, the temblor known locally as Great Earthquake of Eastern Japan is officially tied for fourth in the official record books.

But in many ways, this was an earthquake like no other.

Nearly 60 million people felt direct shaking. The breakdown as measured by theModified Mercalli Intensity scale, which is calibrated to measure surface impact rather than seismic energy: “2.14 million (VIII – Severe), 29.96 million (VII – Very Strong), 19.69 million (VI – Strong) and 7.07 million (V – Moderate).”

Then the tsunami hit, a 30-foot killer wave weaponized with debris, racing inland with pedal-to-the-metal speed, flattening buildings, drowning fields, swamping towns, shredding lives.

This being Japan, where all phones are smart and digital cameras abound, the catastrophe was documented in staggering detail. In near real-time, images raced across the planet even faster than the tsunami. We watched in collective global horror as dark water oozed across the land, snuffing out all signs of life and civilization in its path. From Tokyo came video of chandeliers shaking, computers tumbling, books falling. We felt people’s terror in the crazy angles of videotaped escapes. We cried out as shards of glass rained down on frightened office-workers.
