Remote Sensing of Atmospheric and Ionospheric Signals Prior to the Mw 8.3 Illapel Earthquake, Chile 2015

摘要: In the present study, a number of atmospheric and some ionospheric anomalies are analyzed, which were recorded prior to Mw 8.3 Illapel earthquake September 16, 2015. This very large occurred in Central Chile, close coast, as result thrust faulting on interface between Nazca Plate South American continent. Using remotely sensed data extracted from NASA/Giovanni, NOAA/NCEP, NOAA/NGDC, observed that co-registered 35–40 25–30 days main shock, respectively. With reference long-term time series over epicentral area, significant for cloud cover, geopotential height, precipitation rates, surface air pressure, omega, stream function, wind vectors—all window August 5–10, 2015, shock. Anomalous TEC maps same period. Satellite images indicate formation an unusual cyclone, presumably triggered by turbulences abnormal conditions including strong vertical winds.
