bpptkg-richter is a Python library for computing Richter local magnitude scales on BPPTKG seismic network.

Install using pip:

pip install -U bpptkg-richter

This package provides some utilities for computing Richter local magnitude scales on BPPTKG seismic network (VG). Currently supported stations are MEDEL (Deles), MELAB (Labuhan), MEPAS (Pasarbubar), and MEPUS (Pusunglondon). For current version, it only support Z component.

You may want to install ObsPy package, because this package only work on ObsPy stream type. Default network is VG and default component is Z:

from obspy import read
import richter

# Read single station or multiple stations streams
stream = read('/path/to/stream.mseed')

# Compute Richter local magnitude for station MEPAS
ml = richter.compute_ml(stream, 'MEPAS', network='VG', component='Z')

# Compute Wood-Anderson zero-to-peak amplitude in meter for station MEPAS
wa_ampl = richter.compute_wa(stream, 'MEPAS', network='VG', component='Z')

# Compute count amplitude peak-to-peak for station MEPAS
app = richter.compute_app(stream, 'MEPAS', network='VG', component='Z')

or for short:

from obspy import read
import richter

stream = read('/path/to/stream.mseed')

ml = richter.compute_ml(stream, 'MEPAS')
wa_ampl = richter.compute_wa(stream, 'MEPAS')
app = richter.compute_app(stream, 'MEPAS')

For current version, on computing local magnitude (compute_ml) and Wood-Anderson amplitude(compute_wa), the only supported component is Z component.

compute_app support other components, for example:

app = richter.compute_app(stream, 'MELAB', component='E')
