Another day, another major earthquake — this time, a magnitude 6.9 tremblor that killed at least 300 people in China’s Qinghai province. I’ve been talking to a lot of seismologists lately, and they all agree that the recent cluster of devastating earthquakes, including the jolt that shook northern Mexico earlier this month, do not point to some planet-wide upheaval; it’s all a statistical coincidence, they say. Well, that may be true, but it sure doesn’t feel that way. It feels like something is up. Not surprising, then, that a few days ago false rumors started proliferating in Southern California that the Big One would strike imminently.
Seismologists’ reassurances would be more soothing if they had a detailed, empirically verified understanding of how earthquakes work. Unfortunately, they’re the result of forces at work deep within the earth that are difficult to gather data on. So the science remains in its early stages. But progress is being made — and soon, you can be a part of the process. As I wrote recently on the Pop Mech website:
As part of their battle to understand and protect against the destructive force of earthquakes, seismologists have gone to extraordinary lengths. They have bored holes deep into the earth’s crust, laid out arrays of sensors hundreds of miles across, and built supercomputers capable of running simulations at teraflop speeds. But the most exciting new effort in cutting-edge seismology involves a piece of instrumentation that’s a good deal less exotic. It’s called an iPhone. Read the rest of this entry »
