Meteorological Parameter Studies During 6 December 2016 Indonesia Earthquake (Mw 6.5)

Abstract

The atmosphere near the ground surface is affected more than the ionospheric region in terms of ionization by the electromagnetic emissions caused by various reasons. One such occurrence is the emission of radon (Rn222) from lithosphere through the deformities of the earth crust during the earthquakes. This creates atmospheric anomalies before any strong seismic activities which seem to be present in the meteorological parameters. The evidence for atmospheric anomalies has yet to be meticulously analysed. The data for analysis can be recorded by receiving through L-type antenna and a detector module having a local oscillator, power amplifier, IF amplifier and data acquisition card. But in this work, the data are satellite data. Here, the event of Indonesia earthquake occurred on 6 December 2016 with magnitude Mw 6.5 analysed for observing the anomalies in meteorological parameters, viz. air temperature, relative humidity, atmospheric pressure and wind speed before and after this earthquake. The variations of these parameters might help to predict the occurrence of the earthquake 2–3 days prior to its occurrence. We obtain certain anomalies in temperature, relative humidity, pressure and wind speed observations. Also, we have found that 30-km depth is very sensitive for Indonesia.
