CSV focal mechanisms output
The CSV output for the focal mechanism search produces one line per solution. Click here to load an example.
Each line has 35 fields, which are preformatted and comma separated. Each field is in one of 7 groups:
EVENT, ORIGIN, FM AUTHOR, MOMENT, MOMENT TENSOR COMPONENTS, NODAL PLANES, PRINCIPAL AXES
| Group | Title | Position | Description |
|---|---|---|---|
EVENT | EVENTID | 1-9 | Unique id number specific to each ISC event. |
ORIGIN | AUTHOR | 11-19 | Author of the origin linked to the focal mechanism solution. |
ORIGIN | DATE | 21-30 | Origin date. |
ORIGIN | TIME | 32-42 | Origin time. |
ORIGIN | LAT | 44-51 | Origin latitude. |
ORIGIN | LON | 53-61 | Origin longitude. |
ORIGIN | DEPTH | 63-67 | Origin depth (km). |
ORIGIN | CENTROID | 69-76 | Flag set to TRUE if the origin is reported as a centroid. Note: if the flag is not set to true, there is still a possibility that the origin is a centroid but was not reported as such. |
FM AUTHOR | AUTHOR | 78-86 | Author of the focal mechanism solution - often but not always the same as the author of the origin. |
MOMENT | EX | 88-89 | Exponent used to convert the scalar moment to units of Nm. |
MOMENT | MO | 91-95 | Scalar moment. |
MOMENT | MW | 97-100 | Moment magnitude. |
MOMENT TENSOR COMPONENTS | EX | 102-103 | Exponent used to convert the moment tensor components to units of Nm. |
MOMENT TENSOR COMPONENTS | MRR | 105-110 | One of six independent moment tensor components. |
MOMENT TENSOR COMPONENTS | MTT | 112-117 | One of six independent moment tensor components. |
MOMENT TENSOR COMPONENTS | MPP | 119-124 | One of six independent moment tensor components. |
MOMENT TENSOR COMPONENTS | MRT | 126-131 | One of six independent moment tensor components. |
MOMENT TENSOR COMPONENTS | MTP | 133-138 | One of six independent moment tensor components. |
MOMENT TENSOR COMPONENTS | MPR | 140-145 | One of six independent moment tensor components. |
NODAL PLANES | STRIKE | 147-152 | Strike of 1st nodal plane. |
NODAL PLANES | DIP | 154-158 | Dip of 1st nodal plane. |
NODAL PLANES | RAKE | 160-166 | Rake of 1st nodal plane. |
NODAL PLANES | STRIKE | 168-173 | Strike of the 2nd nodal plane. |
NODAL PLANES | DIP | 175-179 | Dip of the 2nd nodal plane. |
NODAL PLANES | RAKE | 181-187 | Rake of the 2nd nodal plane. |
PRINCIPAL AXES | EX | 189-190 | Exponent used to convert the eigenvalues of the principal axes to units of Nm. |
PRINCIPAL AXES | T_VAL | 192-197 | Eigenvalue of the T-axis. |
PRINCIPAL AXES | T_PL | 199-203 | Plunge of the T-axis. |
PRINCIPAL AXES | T_AZM | 205-210 | Azimuth of the T-axis. |
PRINCIPAL AXES | P_VAL | 212-217 | Eigenvalue of the P-axis. |
PRINCIPAL AXES | P_PL | 219-223 | Plunge of the P-axis. |
PRINCIPAL AXES | P_AZM | 225-230 | Azimuth of the P-axis. |
