| Zusammenfassung |
| A large earthquake
of M6.6 occurred on 13 February 2001 at 14:22:05 UT in El Salvador. We
detected ionospheric perturbation before this earthquake using GPS data
received from CORS network. Systematic decreases of ionospheric total
electron content during two days before the earthquake onset were observed
at set of stations near the earthquake location and probably in region of
about 1000 km from epicenter. This result is consistent with that of
investigators, which studied these phenomena with several observational
techniques. However it is possible, that such TEC changes are
simultaneously accompanied by changes due to solar wind parameters and Kp
-index. |
