Abstract

The microwave emission at 22 GHz, 2GHz and 300 MHz was experimentally found in association with rock crash in laboratory. This phenomenon could be applied to detect earthquakes or volcanic eruption phenomena which are accompanied with the rock crash. In order to confirm the microwave emission in natural phenomena, we planned a field test at the volcano of Miyake-jima. This paper describes the estimation of the signal to noise ratio of the test, the test site and the measuring system. The obtained data and their analysis showed successful detection of signals at 300 MHz.
