We developed a method using synchrosqueezed transforms (SST) and convolutional neural networks (CNN) to recognize seismic phases from earthquake waveforms. The attention mechanism has added within the CNN to improve the accuracy of seismic phase picking. This approach transforms the 1D seismic signals into a 2D time-frequency representation using a synchrosqueezed transform (SST). We use Stanford Earthquake Dataset (STEAD) to train the proposed method.
