Earthquake Prediction

Earthquake prediction is an imprecise science, and to illustrate the point, many experts point to the story Tangshan, China. On July 28, 1976, a magnitude 7.6 earthquake stuck the city of Tangshan, China, without warning. None of the signs of the successful prediction from a year and half earlier were present. An estimated 250,000 people died.

Unlike thirty years ago, however, earthquake scientists today have a few more tools at their fingertips to help predict temblors. Raymond, a geophysicist(地球物理学家), says the application of an emerging satellite technology “could advance earthquake science towards a better predicative capability.”

The system, known as the Global Earthquake Satellite System (GESS), employs a technology called interferometer synthetic aperture radar (InSAR).（合成孔径雷达干涉测量技术）The technology allows scientists to detect minute deformations（变形）in the Earth’s crust（地壳）. In theory, knowing how and where the Earth’s crust is deforming, combined with knowledge of how earthquakes work, could give scientists a clue that an earthquake is going to happen. Max Wyss, director of the World Agency of Planetary Monitoring and Earthquake Risk Reduction, said that “InSAR is a great new technology that allows us to illuminate the surface of the planet and map the deformation that happens. And it is very reasonable that Earth deformation may happen before an earthquake.”But he also stated that the InSAR technique can not be seen completely reliable because there is little evidence that the Earth actually deforms before a major earthquake.

The InSAR technique involves examining pairs of radar images of the same landscape to determine changes in the land surface over very broad regions to within a couple of inches. The satellites can thus detect slight deformations in the Earth’s crust, which may indicate strain prior to an earthquake.

The space shuttle flew a mission in 2000 that used the technology to create a geographic map of the Earth. A proposal to launch an InSAR equipped satellite is currently before NASA. Scientists hope that within 20 years, several more satellites will launch. Raymond said that while a
