1. A method, comprising:

  • extracting multiple features of activity associated with geomagnetically induced currents from multiple heterogeneous data streams, wherein said extracting is executed by a feature extractor component of a computing device;

    comparing the multiple extracted features to historical data related to geomagnetically induced currents to determine a level of similarity between each of the multiple extracted features and one or more items of the historical data, wherein said comparing is executed by the computing device;

    assigning a level of severity to one or more of the multiple extracted features having a level of similarity with one or more items of the historical data above a given threshold, wherein said assigning is executed by the computing device; and

    generating a notification comprising (i) a prediction of activity associated with geomagnetically induced currents based on the one or more extracted features having a level of similarity with one or more items of the historical data above the given threshold, and (ii) the level of severity assigned to each of the one or more extracted features, wherein said generating is executed by the computing device.
