Abstract

Currently, macroseismic data are mostly obtained through online questionnaires posted on the websites of regional and international seismological agencies. Generally, strong earthquakes lead to a large number of users attempting to access the sites, which often leads to server overloads, the disruption of normal access to seismological sites, and, as a result, a sharp decrease in the efficiency of collecting macroseismic data through online questionnaires. In such cases, the only way to make up for the lack of macroseismic data is to directly ask residents to share their observations and fill out an online questionnaire. The use of instant messaging apps seems to be the best way, because they provide wide coverage and high speeds. The efficiency of this method has been confirmed during two relatively strong earthquakes in the Baikal region (September 21, 2020, M_w = 5.6, and June 8, 2022, M_w = 5.2), which were accompanied by the website crashing. Sending requests to earthquake eyewitnesses via the Viber instant messaging app made it possible to increase the number of responses by 5–8 times.

地震期间使用现代通信技术：如何提高宏观地震数据收集的效率

摘要目前，宏观地震数据大多是通过区域和国际地震机构网站上发布的在线问卷获得的。一般来说，强震会导致大量用户试图访问网站，这往往会导致服务器超载，地震网站的正常访问中断，从而导致通过在线问卷收集宏观地震数据的效率急剧下降。在这种情况下，弥补宏观地震数据不足的唯一办法就是直接要求居民分享他们的观测结果并填写在线问卷。使用即时通讯应用程序似乎是最好的方法，因为它们覆盖面广、速度快。在贝加尔湖地区发生的两次相对较强的地震（2020 年 9 月 21 日，Mw = 5.6；2022 年 6 月 8 日，Mw = 5.2）中，这种方法的效率得到了证实，同时网站也出现了崩溃。通过 Viber 即时通讯应用程序向地震目击者发送请求，使回复数量增加了 5-8 倍。
