| Zusammenfassung |
| Recently, surface
latent heat flux (SLHF) data have been widely used to study the anomalies
before earthquakes. Most studies use the daily SLHF data. Here we use both
the daily SLHF data and the high temporal resolution (four times one day)
SLHF data, and compare the SLHF changes with satellite cloud images at the
first time. We check the data from 1 September to 30 October 2011, and the
result shows that there is really a very high SLHF anomaly (more than
2σ) in the epicenter area just 5 days before the M = 6.1 Russia
earthquake that occurred on 14 October 2011. It should be considered as a
preseismic precursor if judged with previously published methods,
but our comparison
between SLHF change and satellite images shows that the SLHF anomaly is
contaminated by a thick cloud. It is difficult to verify that this SLHF
anomaly is caused by an earthquake and our analysis shows that it is more
related to meteorological reason. This example tells us that scientists must
know the data's meaning before they use it; if not, they may draw a wrong
conclusion. Based on this example, we suggest that previously published SLHF
anomalies before earthquakes should be reanalyzed with our method to exclude
the false anomalies. |
