| Abstract: | To fill the data gap of Natech researches in China focusing on technological incidents triggered by natural hazards,this paper reports our efforts of collecting Natech incidents in China over the last 20 years,which leads to a preliminary Natech incidents database(Natech-DB in China).With Natech-DB the spatiotemporal distribution pattern of China Natech cases are analyzed for several major industries.Generally,Natechs occur or reported most frequently in summer,caused by storm and gale;construction and transportation are the major industries involving reported Natechs.Harnessing recorded meteorological variables over the leading days of each Natech case,our retrospective regressive analysis revealed that fatality number,including the missing,of a storm-or-flood-caused Natech holds significant correlation(r>0.3,p<0.01)with the rain change rate namely,Precipitation Slope over Preceding Days(PSPD),4—5 days prior to the incident.This finding benefits the prognosis of and preparing for Natech incidents in cases of days-lasting precipitation events. |
