| Zusammenfassung |
| Anomalies of multi-parameters (outgoing longwave radiation, surface
latent heat flux, air temperature, relative humidity, and air pressure)
before the 12 May 2008 Wenchuan Ms =8.0 earthquake were discussed in order to
obtain the seismic precursors. Multi-parameter data were computed based on
multi-year background data. The results indicated that these parameters had
significant variations prior to this event. The anomaly of outgoing longwave
radiation was observed firstly, which gives an early warning. Next were air
temperature, relative humidity, and air pressure, which had
quasi-simultaneous variations in the basin and the mountain region close to
the epicenter. The last was surface latent heat flux, which happened the
day before this event. The characteristics of the parameter variations for
this event are similar to other earthquakes, which is demonstrated in some
other publications. The variations can be attributed to solid earth degassing and
chemical reactions in the atmosphere. Additionally, the emission of gases from solid
earth into the atmosphere could be ascribed to the tectonic stress of the
Wenchuan earthquake. |
