Applying petrological research to volcanic risk assessment

现在可以利用火山岩的岩石学特征，不仅可以解释喷发事件后的岩浆储存和运输过程，而且还可以作为一种监测工具，帮助监测机构预测和减轻喷发过程中的火山风险。然而，以这种方式应用岩石学信息的进展目前受到监测机构和学术科学家之间相对较差的合作讨论的阻碍。这在很大程度上是岩石学研究远程进行的副产品，通常是在学术框架内进行的。因此，尽管危险评估和预测喷发方式变化的潜力巨大，但岩石学监测往往被忽视，转而采用更传统的地球物理和地球化学监测技术。我们的目标是通过提供一个论坛，切实落实以蒙特塞拉特苏弗里埃尔山火山为基础的火山监测研究成果，以纠正这种情况。我们计划举办一次研讨会，公认的学术专家将与负责监测火山和评估火山风险的用户会面。他们将讨论岩石学数据在预测和减轻火山灾害方面的应用，考虑岩石学如何解决重要问题，以提高负责机构将喷发的经济和社会影响降至最低的能力。例如，许多喷发是由深处新岩浆涌入引发的；岩石学方法现在可以确定这一过程的程度和规模，这可能有助于确定正在进行的活动的寿命和影响。讲习班还将讨论如何改进目前的合作做法和讨论；如何将收集与最终用户有关的信息纳入现有研究方案，以及机构科学家如何参与数据收集。讲习班的好处将包括改善终端用户和学术界之间的工作关系；在SHV实施岩石学监测的战略；以及专门为满足最终用户需求而设计的研究人员和天文台科学家之间未来互动和知识交流的协议。讲习班的结论将立即在蒙特塞拉特付诸实施，并广泛传播，以便在其他地方应用和发展。

The petrological features of volcanic rocks can now be used, not only to interpret magma storage and transport processes after eruptive events, but also as a monitoring tool that can help monitoring agencies forecast and mitigate volcanic risk during the course of an eruption. However, progress in applying petrological information in this way is currently hampered by the relatively poor collaborative discourse between monitoring agencies and academic scientists. This is largely a by-product of the fact that petrologic research is conducted remotely, often within an academic framework. Thus, despite tremendous potential for hazard assessment and forecasting changes in eruption style, petrological monitoring is often overlooked in favour of more traditional geophysical and geochemical monitoring techniques. We aim to remedy this situation by providing a forum for practical implementation of research results into volcano monitoring, based on the Soufrière Hills Volcano, Montserrat. We plan a workshop where acknowledged academic experts will meet with users responsible for monitoring volcanoes and assessing volcanic risk. They will discuss the application of petrological data to the forecasting and mitigation of volcanic hazards, considering how petrology can address important questions that improve responsible agencies' ability to minimise the economic and societal impact of eruptions. For example, many eruptions are triggered by the influx of new magma at depth; petrological methods can now resolve the degree and scale of this process, which could help to determine the longevity and impact of ongoing activity. The workshop will also address ways to improve current collaborative practices and discussion; how to integrate information gathering relevant to end-users into existing research programmes, and how agency scientists can participate in data gathering. The benefits of the workshop will include improved working relationships between end-users and the academic community; a strategy for implementing petrological monitoring at SHV; and a protocol for future interactions and knowledge exchange between researchers and observatory scientists, designed specifically to address end-user needs. Findings from the workshop will be put into practice immediately at Montserrat and disseminated widely for application and development elsewhere.
