CAUSE OF MICROSEISMS—A THEORY

L. DON LEET and FLORENCE J LEET

World-wide compression of the earth's crust, evidenced from the reduction of surface areas in mountain-making, faulting, and creep and revealed by precise surveys, is proposed as the ultimate cause of microseisms. The strained crust, broken into blocks of many sizes, is "singing." When extensive storm areas move over strained blocks, the regional changes in atmospheric loads cause temporary increases in microseismic activity.
