Abstract:
Gas migration rate(s) are determined using gas measurements from gas migration measurement devices. In response to the gas migration rate increasing, at least one of: air ionization measurements are collected from air ionization measurement device(s), and meteorological measurements collected from air temperature sensor(s), relative humidity sensor(s), and air pressure sensor(s). A latent heat energy release rate is determined using at least two of: the air ionization measurements, the meteorological measurements, and a numerical assimilation model. In response to the latent heat energy release rate increasing, at least one transient outgoing long wave radiation (OLR) anomaly is looked for using atmospheric measurements. In response to observing the transient OLR, at least one ionospheric anomaly is looked for using ionosphere measurements. In response to observing the at least one ionospheric anomaly, a forecast alert that an earthquake is likely to occur within one to four days is generated.
