Collaborative Research: Continuous acoustic and volcanic debris records of the deepest explosive submarine eruption ever observed

虽然地表火山喷发既常见又引人注目，但迄今为止，最大量的火山物质是在海底喷发的，而海底火山喷发还没有被观察到，对海底火山喷发的了解也很少。最近对西太平洋三个地点喷发的直接观测提供了这种活动的非常罕见的一瞥。在劳盆地的西马塔（West Mata），有一个地点安装了许多水听器，用来记录火山喷发的声音信号，这些声音信号可以用来深入了解火山喷发过程。该项目旨在分析来自四套仪器的数据，以定位声波信号的来源，了解火山震颤的来源，并将声波活动与火山灰和碎屑的产生联系起来。更广泛的影响包括提高对地球基本过程的了解、公众宣传和教育。

While surface volcanic eruptions are both common and dramatic, by far the greatest volume of volcanic material is erupted on the seafloor, where they have not been observed, and remain poorly understood. Recent direct observations of eruptions at three sites in the western Pacific have provided a very rare glimpse of this type of activity. One site, West Mata in the Lau basin, was instrumented with a number of hydrophones to record acoustic signals (sound) from the eruption that can be used to gain insights into the eruptive process. This project has the aim of analyzing the data from a suite of four instruments to locate the sources of the acoustic signals, understand the sources of volcanic tremor, and correlate the acoustic activity with the production of volcanic ash and debris. Broader impacts include improved understanding of fundamental earth processes, public outreach and education.
