Research on quick earthquake disaster investigation and evaluation using cloud monitoring method

Seismic intensity map reflects the actual situation of destruction in a certain area after the earthquake, and it is of great significance in guiding relief work and assessing damage loss. Earthquake professionals make intensity map usually through visiting sites personally, sometimes combining with strong motion records analysis and remote sensing seismic interpretation. However, these methods tend to spend a lot of time, especially in the case that the earthquake-affected area is very large. Based on cloud monitoring method proposed, we developed software, which can quickly investigate the seismic intensity distribution and draw the intensity map after the earthquake using the big data collected by individual smart phone questionnaire in earthquake zone. According to seismic attenuation law, we generated some seismic intensity values to test our system and successfully drawn out of the seismic intensity map. When earthquake occurred in a certain area, all the people who equipped this software on their smart phones, can fill in the intensity questionnaire and take scene photos, then submit these to our server through the software. Questionnaires and scene photos can be classified by our server. When the amount of data submitted meets the requirements, the server can draw the accurate intensity map in a few seconds.
