The DMC is now calculating aftershock sequence figures and animations for all M7.0+ earthquakes. The movie, aftershock and background seismicity figures are updated hourly for the first day and twice daily for the first 10 days. GCMT focal mechanisms are plotted when available. The catalog has been backfilled with events to 1980.
