Data sets

Improved location procedures at the International Seismological Centre (http://www.isc.ac.uk/iscbulletin/search/catalogue/) I. Bondár and D. A. Storchak https://doi.org/10.1111/j.1365-246X.2011.05107.x

Short summary

Early emergency response requires improving the utilization value of the data available in the early post-earthquake period. We proposed a method for assessing seismic intensities by analyzing early aftershock sequences using the robust locally weighted regression program. The seismic intensity map evaluated by the method can reflect the range of the hardest-hit areas and the spatial distribution of the possible property damage and casualties caused by the earthquake.
