| Zusammenfassung |
| The complexity in the tsunami phenomenon makes the available warning systems
not much effective in the practical situations. The problem arises due to
the time lapsed in the data transfer, processing and modeling. The modeling
and simulation needs the input fault geometry and mechanism of the
earthquake. The estimation of these parameters and other aprior information
increases the utilized time for making any warning. Here, the wavelet
analysis is used to identify the tsunamigenesis of an earthquake. The
frequency content of the seismogram in time scale domain is examined using
wavelet transform. The energy content in high frequencies is calculated and
gives a threshold for tsunami warnings. Only first few minutes of the
seismograms of the earthquake events are used for quick estimation. The
results for the earthquake events of Andaman Sumatra region and other
historic events are promising. |
