| Zusammenfassung |
| The paper presents an analysis by using the methods of Eddy field calculation
mean and wavelet maxima to detect seismic anomalies within the outgoing
longwave radiation (OLR) data based on time and space. The distinguishing
feature of the method of Eddy field calculation mean is that we can calculate
"the total sum of the difference value" of "the measured value" between
adjacent points, which could highlight the singularity within data. The
identified singularities are further validated by wavelet maxima, which using
wavelet transformations as data mining tools by computing the maxima that can
be used to identify obvious anomalies within OLR data. The two methods has
been applied to carry out a comparative analysis of OLR data associated with
the earthquake recently occurred in Haiti on 12 January 2010. Combining with
the tectonic explanation of spatial and temporal continuity of the abnormal
phenomena, the analyzed results have indicated a number of singularities
associated with the possible seismic anomalies of the earthquake and from the
comparative experiments and analyses by using the two methods, which follow
the same time and space, we conclude that the singularities observed from
19 to 24 December 2009 could be the earthquake precursor of Haiti earthquake. |
