Total electron content [TEC] anomaly appeared in the ionosphere, sharp increase approx. 10 hours before
M 5.3 – 138km NE of Tocopilla, Chile 2017-07-22 06:29:50 UTC at a depth of 48.7 km.
Note: these types of anomalies caught on these maps are rarely directly over epicenter [but very close] due to a few reasons, such as the angle of the anomaly to the station/satellite collecting data, images are being generated by combining data sources and averaged, etc.
