摘要

We present an analysis of the information collected by the ?Sintio un sismo? (SUS) web-based system. One of the most devastating events in central Mexico in the past 35 yr struck near the Mexican states of Puebla and Morelos on 19 September 2017. At the moment of the event, several programs and projects were in place to monitor and perform quick assessments of the magnitude of the earthquake and the severity of its effects on the population and infrastructure. The SUS platform gathers questionnaires designed in Spanish to estimate macroseismic intensities. The availability of such a system in the dominant language of the country permits a broad reach, only limited by the disparity of the services and internet access. By analyzing residuals of the median attenuation intensity of the event, we confirm previous observations on the site and regional effects in Central Mexico such as the strong influence of the Trans-Mexican volcanic belt on the ground-motion amplification. In addition, we obtained correlations between peak parameters and macroseismic intensities that reveal the character of the affected structures' responses. We emphasize the potential usability of systems similar to the SUS at the regional level and their impact on the decision-making process and support for further research using all available datasets.

(SUS)基于Web的系统。 2017年9月19日在墨西哥普埃布拉和莫雷洛斯州墨西哥州墨西哥州附近的35岁处于墨西哥中部最具破坏性的事件之一。在活动的那一刻,有几个方案和项目就可以监测并进行了快速评估地震幅度和对人口和基础设施影响的严重程度。 SUS平台收集以西班牙语设计的问卷来估计宏观激烈的强度。该国主导语言的这种系统的可用性允许广泛的范围,仅受到服务和互联网接入的差异的限制。通过分析事件中值衰减强度的残差,我们确认了墨西哥中部地区的现场和区域效应的观察,例如跨墨西哥火山带对地面运动扩增的强烈影响。此外,我们获得了峰值参数和宏观主义强度之间的相关性,这些强度揭示了受影响的结构响应的特征。我们强调系统的潜在可用性与区域一级类似的系统及其对使用所有可用数据集进行进一步研究的决策过程的影响。
