magnetic field observations for the 8 december 2016 mw 6.0 china earthquake

A precursor is a parameter of change that acts prior to the occurrence of a possible earthquake and thereby alerts a series of changes through which one can predict the seismic incidents. instantaneous anomalies within the geomagnetic data are perfect example of a precursor. the current study aims to investigate the fluctuations of the magnetic field before and after a seismic event. this study uses the assessed geomagnetic data extracted from three stations located near shihezi, china which underwent a 6 mw earthquake at a depth of 17.6 kms on december 8, 2016 at 05:15:04 (utc). characteristic curves have been depicted for each station by continual mapping out of elicited 24-hour data, two weeksbefore and a week after the shihezi earthquake. the results indicate an anomaly occurred less than 10 days prior to the earthquake through the fluctuations in the amplitude of magnetic field. using this method, it can be pointed out that such anomalies are directly associated with an earthquake.
