摘要
On November 14, 2016(NZDT), a 7.8 magnitude earthquake struck the northeast coast of the South Island in New Zealand. A tsunami swept onto the coastlines with wave-heights of 2.5 m at Kaikoura. This earthquake is the largest event in the region since a magnitude 7.5 earthquake that occurred 100 km to the northeast in October 1848. The days immediately following a natural disaster are particularly challenging for authorities and aid organisations who need to make decisions relating to deployment and distribution of resources. Rapid Damage Mapping(RDM)is a tool developed by Tonkin + Taylor International Limited(T+TI) whereby integrated disaster mapping information is assembled within the first 24 to72 hrs of an event. The Committee on Data of the International Council for Science(CODATA) Task Group of Linked Open Data for Global Disaster Risk Research(LODGD) organized ChinaGEOSS portal to access TripleSat and JL-1 satellite images immediately following the devastating Kaikoura earthquake.An internet based Project Orbit portal was set up for use by all response and recovery organisations in New Zealand. While the recent RDM response work was largely reactive in nature, the data set compiled during this work provides a valuable resource, presenting opportunities to apply a more proactive and refined approach to similar RDM work in the future.The recent RDM work provides valuable insight into key vulnerabilities that evolved after the earthquake, and helped to identify more than 10,000 landslips in the area.
