Focus Earth The lzmit Earthquake: A Quick Post-Seismic Analysis with Satellite Observations

摘要

For the lzmit earthquake, as for previous similar events all over the World, ERS SAR interferometry has provided extremely useful results. A quantitative analysis was performed to assess the overall displacement on the surface. It is believed that an image pair from an ascending and a descending pass might be sufficient, together with tectonic information, to estimate the movement quantitatively. In this particular case, the favourable situation with respect to both satellite orbit and tectonics allowed the dislocation to be determined using a single interferometric pair, together with geological information.
