The size of an earthquake at its source is measured from the amplitude (or sometimes the duration) of the ground motion recorded on seismic instruments, and is expressed in terms of magnitude. Magnitude is a logarithmic measure and usually is measured based on data recorded by multiple stations after applying some pre‐proccessing and corrections to the raw signals. Here, we introduce the first successful deep‐learning approach to estimate directly the magnitude from raw seismic signals recorded on a single station.

magnet's Issues

Using MagNet on regional and Teleseismic Earthquakes

Dear Mostafa;
I have some problems trying to find our how is is the entry of the MagNet prediction method.

Reading the file MagNet.py
kdp = KerasDropoutPrediction(model)
predic, al_unc, ep_unc, comb = kdp.predict(x_train, monte_carlo_sampling)

is it model file "mag_regressionLSTM_ML_multiobservations_1000_067.h5" ?
is x_train the raw data of one of the components of a seismogram? it seems that x_train is the output of datat_reader(file_name, file_list) and inside the method is filled
X = np.zeros([len(file_list), 3000, 3])
Could let me know if x_train must be a numpy array or a list and very important the dimensions.
why is monte_carlo_sampling = 50

version

Hello, can you tell me which version of tensorflow and keras you are using
