K1 Sismología - Innovaciones tecnológicas AB Deep Learning (DL) has shown capability in many areas of impact on everydaylife. The paper proposes a DL architecture tailored for event detectionfrom examining the time evolution of a signal. With temporal characteristicsextracted by a Convolutional Neural Network (CNN) encoder and fedas input to a recurrent neural network, the model targets the detection of apossibly occurring investigated event in the given time interval. The utilityof DL methodologies to solve physical problems is demonstrated for an applicationof the complex experimentally-studied existing interaction betweenSchumann Resonance (SR) and seismic activity. SR signals are electromagneticwaves propagating along the Earth-ionosphere cavity. Intense lightning activity is continuously present at the same locations around the world, beingsensitive to physical perturbation. Seismic activity modifies this steadylightning pattern. The new DL model is applied to answer the researchquestion of whether the variation of the SR signal is truly a verifiable forerunnerof seismic activity. Several parameter configurations are explored,either model-related or linked to criteria for selecting seismic events. Resultsshow preliminary evidence about the relation between distance-intensityspace and SR perturbation, and provide valuable corroboration about thesensitivity of the sensor to a specific azimuth between the observatory andthe Earthquake (EQ) epicenter, hence argumentatively supporting the SRtemporal characteristics as an early seismic warning. This is the first generalizationof seismic disturbance as a derivative of the SR, based only on itssignal time series variation, as a hypothesized precursor of the EQ event.
