...keeping close tab on the buildup of stresses along a fault. But the knowledge, instruments and funds necessary to monitor many miles of fault line and interpret any findings simply did not exist. Earthquake prediction did not draw much attention until 1949, when a devastating quake struck the Garm region of Siberia, causing an avalanche that buried the village of Khait and killed 12,000 people. Stunned by the disaster, the Soviets organized a scientific expedition and sent it into the quake-prone area. Its mission: to discover any geologic changes-in effect, early warning signals-that might occur before...
...retroactive prediction of that powerful quake, the Caltech researchers demonstrated that it was primarily the velocity of the P waves, not the S waves, that changed. Their figures were significant for another reason: the P-wave velocity change was not caused by a quirk of geology in the Garm region or even in the Adirondacks, but was apparently a common symptom of the buildup of dangerous stresses in the earth...
...rises because air is not a good conductor of electricity. The cracks also increase the surface area of rock exposed to water; the water thus comes in contact with more radioactive material and absorbs more radon-a radioactive gas that the Soviet scientists had noticed in increased quantities in Garm-area wells. In addition, because the cracking of the rock increases its volume, dilatancy can account for the crustal uplift and tilting that precedes some quakes. The Japanese, for instance, noticed a 2-in. rise in the ground as long as five years before the major quake that rocked Niigata...
...motion of the earth in a direction perpendicular to their path. Because a quake's P waves travel through the earth slightly faster than its S waves, they arrive at seismic listening posts ahead of the S waves. While investigating the small tremors that often occur in the Garm region south of the Central Asian city of Tashkent, Russian seismologists were surprised to discover that in the days or weeks before a serious jolt, the relative velocities of the two types of waves changed. The interval between arrival times decreased significantly. Then, just before a big quake, the velocity...
