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.

地震期间现代通信技术的使用：如何提​​高宏观地震数据收集的效率

摘要

目前，宏观地震数据主要通过区域和国际地震机构网站上发布的在线调查问卷获得。一般来说，强震会导致大量用户尝试访问站点，往往会导致服务器过载，影响地震站点的正常访问，从而导致宏震数据采集效率急剧下降。在线调查问卷。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察结果并填写在线调查问卷。使用即时通讯应用程序似乎是最好的方式，因为它们提供了广泛的覆盖范围和高速度。该方法的有效性在贝加尔湖地区两次相对强烈的地震（2020年9月21日，M _w  = 5.6和2022年6月8日，M _w  = 5.2）中得到了证实，这两次地震都伴随着网站崩溃。通过 Viber 即时通讯应用程序向地震目击者发送请求，可以将响应数量增加 5-8 倍。
