If there’s a bright side to the recent earthquake in Japan, it’s the fact that it was a truly monster event. The damage has been appalling, but it’s not something we should expect to see very frequently. In fact, there were only 11 of this class of “megathrust” earthquakes during the entire 20th century.

However, there have been five megathrust earthquakes in just the past five years, and Yale geophysicist Jeffrey Park says this kind of clustering is far from unprecedented. So we might be in store for a few more. And for Japan in particular, the news is even worse:

[Several years ago] Ross Stein and his USGS colleagues discovered that the stress increments of past large earthquakes were good predictors of where the next large earthquake would occur. Long after the aftershocks subsided — months, years, or decades after — another earthquake of similar size often broke within the next segment of the fault zone.

….An irregular series of large, damaging earthquakes shook the North Anatolian Fault in the twentieth century from east toward the west across modern-day Turkey, reaching the Sea of Marmara in 1999 with the Izmit earthquake….More germane to Japan, the 9.3 Sumatra-Andaman megathrust earthquake in December 2004 loaded the next subduction-zone segment to the south, and this segment generated an 8.6 megathrust event only three months later in March 2005.

No prediction can be made today for Japan, but it is safe to project a sharply increased probability for a major earthquake on the broad, simple subduction-zone segments both north and south of the Tohoku rupture zone. The segment to the south lies offshore the Tokyo metropolitan area.

I don’t really have anything to say about this. It’s just plain bad news. More at the link.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
