The aim of this research is to provide an original contribution to the investigation of local macroseismic variations in urban areas by means of questionnaire surveys. In this paper, we propose a meth...
Re-evaluation of early instrumental earthquake locations: methodology and examples
earthquake location macroseismic locations
2015/9/14
The difficulties of locating earthquakes in the early instrumental period are not always fully appreciated. The networks were sparse, and the instruments themselves were of low gain, often had inappro...
A new methodology for in-flight radiometric calibration of the MIVIS imaging sensor
hyperspectral airborne scanner MIVIS radiometric calibration data quality
2015/9/7
Sensor radiometric calibration is of great importance in computing physical values of radiance of the investigated targets, but often airborne scanners are not equipped with any in-flight radiometric ...
