Abstract: A plurality of cameras 20 e.g. IP cameras used for surveillance or meteorological observations provide a visual input of a location over a network. A coupling correction is performed between a shaking of the camera with respect to the visual input by subtracting velocity vectors of the plurality of cameras from velocity vectors of pixels defining the visual input to provide a processed input. It is determined whether a shaking identified in the processed input is above a predetermined threshold based on the processed input, thereby detecting one or more anomalies. From the one or more anomalies, at least one of a location, magnitude, or depth of an earthquake are inferred based on the shaking identified in the processed input of each of the plurality of cameras. The intensity of the earthquake may be determined. Shaking may be determined from pixel-wise changes in the processed input, by performing a spectral analysis and determining a spectral decomposition. Parameters of the earthquake may be detected using a trained artificial intelligence model. External seismic data may be used to calibrate the cameras.
