Abstract

In this paper, typical earthquake disaster life loss assessment models are applied to verify and calculate the historical earthquake cases in the Gansu Province since 1966. The assessment accuracy and applicability of various models in the Gansu Province are studied by means of actual earthquake cases. Results show that: (1) For Ms<5.5 and 5.5≤Ms≤6.0, a life loss assessment model is based on population density, another model based on epicentral intensity proposed, and the national earthquake disaster emergency assessment model are relatively accurate and basically included in the reasonable range; for Ms>6.0, characteristics of the assessed regions, such as physical geography and social economy, should be analyzed to correct the model calculation results and to receive comprehensive assessment results, so as to support emergency decisions. (2) Earthquake disaster life loss assessment models are regionalized and the assessment results are obviously regional. Assessment results of the earthquakes occurred in Hedong Region are not accurate for Hexi Region of Gansu Province.
