1. An apparatus for event detection of passive seismic data, the apparatus comprising:
processing circuitry configured to:
extract features from the passive seismic data based on a backbone subnetwork of a residual deep neural network;
adjust parameters of the backbone subnetwork based on the extracted features;
generate bounding box proposals for a region of interest (ROI) in the passive seismic data based on the extracted features being input to a region proposal network of the residual deep neural network;
classify the bounding box proposals into two groups, each bounding box proposal in a first group indicating that a corresponding seismic signal presents in the ROI, each bounding box proposal in a second group indicating that no seismic signal presents in the ROI; and
determine at least one seismic signal in the ROI from the first group of bounding box proposals.
