Ionoquakes from groundshakes
Atmospheric phenomena might also be used to detect certainongoing earthquakes. According to Robert L. Showen and his colleagues at SRI International in Menlo Park, Calif., earthquakes that shake the ground up and down, rather than causing it to slip and slide sideways, trigger atmospheric pressure waves. The disturbance produced by these waves in the ionosphere is known as an ionoquake.
Showen and others have detected a few ionoquakes followingearthquakes while probing the ...
