Columns Heading Sub-heading Description
17-54 LONG Longitude (listed to thousandths of a
degree, but not necossarily accurate to
that level.) Negative values indicate
west longitudes.
56 QUAL Code used to indicate the quality of
58-63 DEPTH
the epicenter (see table 2).
58-62 KMS Focal depth in kilometers (listed to the
nearest tenth of a kilometer, but not
necessarily accurate to that level).
63 QUAL Code used to indicate the accuracy of
the depth (see table 3).
65-67 NUM STA Number of stations used in the
hypocenter computation.
69-71 HYP SRC CODE Hypocentral data source (see table 4).
73-79 m b Body-wave magnitude estimate, if
available. Different sources may vary
significantly in the method used to
compute mb-magnitudes. References
describing the method of magnitude
computation are given in table 5.
73-75 MAG Magnitude value, given to the
nearest tenth of a unit.
77-79 SOURCE Three-letter code indicating the
magnitude sGzrce (see table 5).
81-88 MS Surface-wave magnitude estimate, if
available. Table 5 gives references
which describe the computation of these
magnlttvdes.
81-83 MAG Magnitude value given to the nearest
tenth of a unit.
84 COMP Seismogram component used for the
magnitude determination. H indicates the
horizontal component and Z Indicates the
vertical component.
