The development of a resilient society is a major challenge for growing human population faced with abundant natural hazards. During and after the May 22, 2021 eruption of Nyiragongo, the local population was surprised and scared by the subsequent seismicity and associated surface fracturing, coupled with the alert of a possible new eruptive vent opening in Goma (Democratic Republic of Congo) and/or Gisenyi (Rwanda). The creation of a toll-free phone number enabled the population to record fractures and gas/thermal anomalies affecting the area. Such work was fundamental in enabling scientists and authorities to assess the associated risks. Crucially, gas data showed that the degassing through fractures did not represent direct transfer of magmatic volatiles but was more likely of superficial origin. Surprisingly, this participatory work revealed that the first fractures appeared several weeks before the eruption and their opening was not detected by the monitoring system. This firmly underlines the need for scientists to anchor citizen science in monitoring strategies.
建设有韧性的社会是人类面对大量自然灾害时所面临的主要挑战。2021 年 5 月 22 日尼拉贡戈火山喷发期间和之后，当地居民对随后发生的地震活动和相关的地表破裂感到惊讶和恐惧，再加上有关戈马（刚果民主共和国）和/或吉塞尼（卢旺达）可能出现新的喷发口的警报。创建一个免费电话号码使居民能够记录影响该地区的裂缝和气体/热异常。这项工作对于科学家和当局评估相关风险至关重要。至关重要的是，气体数据表明，通过裂缝排放的气体并不代表岩浆挥发物的直接转移，而更可能是浅层起源。令人惊讶的是，这项参与式工作表明，第一批裂缝出现在喷发前几周，而监测系统并未检测到裂缝的张开。这有力地强调了科学家需要将公民科学纳入监测策略的必要性。
