Introduction

After a severely destructive earthquake occurs, quickly and accurately determine the type of earthquake disaster, the extent and scope of the earthquake disaster, is the earthquake emergency rescue command and operation. Important basis for movement. Remote sensing technology has the characteristics of all-time, all-weather, and not affected by the damage of the earthquake in the earthquake-hit area. Therefore, the earthquake should be used after the earthquake. In the emergency rescue, the disaster situation information of the earthquake-stricken area can be obtained quickly and comprehensively. There are many types and wide distribution of earthquake disasters, and different types of disaster information are provided. There are obvious differences in the objects and methods of taking and evaluating, and it is difficult to adopt a single standard to regulate. For coordinated, orderly, efficient and accurate extraction and evaluation To estimate the main types of earthquake disasters, it is necessary to standardize the methods, indicators, procedures and results of remote sensing evaluation. Disaster Remote Sensing Assessment" series of standards. This standard is based on a large number of remote sensing-based seismic disaster information extraction and evaluation research results in the past two decades, and summarizes the.2008 Wenchuan The magnitude 8.0 earthquake, the.2010 Yushu magnitude 7.1 earthquake, the.2010 Haiti magnitude 7.0 earthquake, the.2013 Lushan magnitude 7.0 earthquake and the.2014 Ludian earthquake The actual evaluation experience of earthquake disaster degree and earthquake intensity based on remote sensing after the occurrence of multiple earthquakes at home and abroad such as the 6.5 earthquake, refer to GB/T 17742-2008 "China Earthquake Intensity Table" and GB/T 18208.3-2011 "Seismic Field Work Part 3.Investigation Specifications" The methods and technical requirements for earthquake disaster investigation and earthquake intensity assessment were formulated. Among them, the main basis for seismic intensity evaluation of this standard is The building types and damage categories obtained from the interpretation of the remote sensing images of the earthquake-stricken area obtained after the earthquake occurred, and the related methods and indicators have been Detailed regulations are made in DB/T 75-2018 "Evaluation of Building Damage by Remote Sensing of Earthquake Disaster". Therefore, this standard is damage to buildings Further application of the assessment results. Earthquake disaster remote sensing assessment of earthquake intensity

1 Scope

This standard specifies the content, method and result expression of seismic intensity evaluation based on remote sensing. This standard applies to the use of remote sensing to carry out seismic intensity assessment.
