CHANGES IN GEOMAGNETIC VARIATIONS ASSOCIATED WITH THE 12 JANUARY 2020 TAAL VOLCANIC ERUPTION
Abstract
The results of instrumental observations of geomagnetic variations caused by eruption of Taal Volcano on January 12, 2020 are given. Its geographical coordinates is 14.002? N, 120.993? E. Taal volcano is located within the Macolod Corridor in the large convergence zone between the Eurasian and Philippine tectonic plates which is characterized by active volcanism, crustal thinning, extensive faulting and block rotations. The data in the form of one-minute interval means which are available on web-site of the INTERMAGNET network are used. It is should note that low magnetic activity is observed (the geomagnetic planetary Kp-index did not exceed 2). Moreover, in presented research geomagnetic anomalies are analysis in period of seismic events which are identified by using catalogs of Geophysical Service of the Russian Academy of Sciences (Russia, Obninsk, Kaluzhskaya obl.), the US Geological Survey (Earthquake Hazards Program, USGS) and the Philippine Institute of Volcanology and Seismology. It was found that geomagnetic anomalies are observed in the Earth?s magnetic field at different distances from the volcano both during the period of its active eruption and during the period of volcanic tectonic earthquakes. It should be noted that the extraction of geomagnetic anomalies is difficult, since magnetic recordings made at the INTERMAGNET observatories contain anomalies caused by a series of earthquakes in Puerto Rico and other seismic events. In general, amplitudes of geomagnetic anomalies do not exceed tens of nT.
