Abstract
The probability of a volcanic eruption is predicted by simultaneously receiving long-wave radiation signals from magma at at least four points in the vicinity of the magma, cross-correlating the received signals to detect time lags among the signals, calculating the site, magnitude and shape of the magma from the time lags, and judging the likelihood, time, scale and site of a volcanic eruption from time-course changes in the calculated site, magnitude and shape of the magma.
