The Roar of Japan’s 9.0 Quake

 

 

This sound is terrifying even a year later. It’s the voice of Japan’s 9.0 temblor and its aftershocks. Zhigang Peng at Georgia Tech’s School of Earth and Atmospheric Sciences converted the quake’s seismic waves into sped-up audio files that we can hear. 

The clip above was taken near the coastline of Japan between the nuclear reactor at Fukushima Daiichi and Tokyo. The initial blast is the 9.0 mainshock. Following that you can hear aftershocks, popping sounds, as the earth’s plates slip into new positions. 

 

 

Here’s Peng’s recording of the 2011 Japanese earthquake taken from seismic measurements thousands of miles away in California. The quake created subtle movements deep in the San Andreas Fault known as distant triggering.

You can hear the initial noise, which sounds like thunder and corresponds with the Japanese mainshock. Afterwards a continuous high-pitch sound, like rain turning on and off, reflects continuing tremor activity at the fault, as heard from afar in California.

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
