Harvard University Researchers developing models to Predict the Strength of Earth Quake


Harvard research team discovered that earthquake activities are actually organized chaos rather than pure chaotic event as scientists had previously believed.

The team began by examining patterns of seismic signals — transient waveforms that radiate from the first rupture in a fault, a thin seam of crushed rock separating two blocks of the earth’s crust. An earthquake occurs when the blocks break free. Scientists read these waves using an underground instrument called a seismometer that translates motions into a graph called a seismogram. “Seismograms give us information about what happened on the fault at the place where the earthquake occurred,” said Denolle.
