Comparison, for the earthquake and heavy rainfall events considered in figure #, between the density of geo-localized mentions inside and outside the affected areas.

For earthquakes, the analyses were made considering all tweets captured during the calendar day of the earthquake (i.e. November 11, 2019 for the Teil earthquake). For episodes of heavy rainfall, tweet exports correspond strictly to the time windows of cumulative rainfall.

针对地震场景的分析均基于地震发生当日捕获的全部推文开展，例如泰尔（Teil）地震对应的分析时段为2019年11月11日。针对强降雨事件，所用推文导出数据严格匹配累积降雨量对应的时间窗口。
