Abstract: A prediction method for changes of physical parameters after earthquakes includes: obtaining a precipitable water vapor after an earthquake in a target monitoring area during a historical period; verifying the accuracy of the precipitable water vapor collected in the historical period; obtaining thermal anomaly data of the land surface temperature after the earthquake in the target monitoring area during the historical period; determining a time difference between peak of the precipitable water vapor and peak of the thermal anomaly of the land surface temperature; when the earthquake occurs again in the target monitoring area, detecting a time point corresponding to the peak of the thermal anomaly of the land surface temperature in the target monitoring area, adding the time point to the time difference to obtain a predicted time point of the peak of precipitable water vapor, and outputting the predicted time point as a time point of secondary disaster.

Abstract: A method and system for monitoring an extraordinary rainstorm based on multi-source data is provided. The method includes: acquiring a current moment of a target region; dividing a target time period into n rain events by means of a time window; inverting precipitable water vapor within each rain event; acquiring an accumulated rainfall per m hours within each rain event; computing, according to precipitable water vapor and the accumulated rainfall per m hours within each rain event, a mutual conversion speed V between the precipitable water vapor and the accumulated rainfall; indicating, if the conversion speed is greater than or equal to 1, that a rainfall is excessive and the extraordinary rainstorm is going to occur after the current moment; and indicating, if the conversion speed is less than 1, the rainfall is insufficient and the extraordinary rainstorm is about to end.

Abstract: The present disclosure provides techniques for monitoring a cross site scripting attack. These techniques may receive and reply to, by a computing device, a service request from a client terminal. The computing device may then redefine a scripting internal function applied by the cross site scripting attack, and return redefined information for the scripting internal function to the client terminal. The computing device may monitor calling information of the client terminal in relation to the redefined scripting internal function, and analyze the security of the calling information. The computing device may monitor an attacking source, an attacking time period, leakage information in the attack, and/or a vulnerability point in the attack that are associated with the cross site scripting attack.
