Real-time data for station PPFSC: Seismogram shows a single vertical-component seismogram, and spectrogram, showing the relative distribution of energy between 0 and 10 Hz (bottom to top). Data will nominally be shown for about the last 2 hours, and should auto-update every 1 minute. Timing is in Universal coordinated time (UTC), and is either 4 or 5 hours later than Georgia, depending on daylight saving time. Small clock errors may remain in this station.

These images are normally filtered to retain signal between 0.5 and 2 Hz (band-pass filtered between 2 and 0.5 seconds). This removes some long-period noise, and some building noise. Waveforms are more sensitive to large distant earthquakes.
Note: spectrogram is unfiltered.
