Date
Dates are given as "m1/d1 - m2/d2" where m1 is the starting month, d1 is the starting day, m2 is the ending month, and d2 is the ending day. For the exact time of the start and end of the record, download the information (back side of seismogram) file that accompanies each seismogram file.
Typically, each recording covers about one day except for some single-component long-period recordings that cover two days.

Instrument
The instrument type is either "SP" for short-period recording and "LP" for long-period recording.

Components
The components are "Z" for vertical, "NS" for north-south, and "EW" for east-west. "Z&EW" indicates that this trace contains both Z and EW components.
The link with each component, e.g., Z, allows the image of the seismic recording to be downloaded. Note that the size of the file given in brackets can be large and may take a while to download completely. The image of the back side of each recording (often showing more detailed information about the recording such as the start and end times) can be obtained from the "Info" link. The information files are typically 90 MB.
The image files are in TIF format (.tif).
