Regional Coda Magnitude in Central Asia
Our data consist of over 3000 broadband records from stations WMQ, MAK(Z) and LZH.
We smooth envelopes of bandpassed seismograms.
A linear fit to distance is used to predict coda decay rate and obtain coda source factors.
Another linear fit to distance is used to correct coda source factors.
We obtain higher inter-station consistency from coda than from Lg (0.7-1 Hz).
However, biases affect these results as we show next.
