Radio Emission from Earthquakes

Abstract

There exists an extensive world literature concerned with radio emissions from earthquakes. The great majority of reports pertain to emissions at very low frequencies, in the range below 100 khz. I will describe a different kind of emission that appears to have been associated with the great Chilean earthquake of 22 May 1960. The evidence that we recorded signals related to that quake is indirect and has elicited little response from the seismological community. The principal data and interpretation were published some time ago. Now I would like to stress the opportunity this phenomenon presents for enriching the data base relevant to earthquakes, perhaps even enabling spacecraft observations of seismological events.
