2014年2月印尼克卢德火山爆发，摧毁了火山附近的大部分仪器，我们使用远程地震和次声传感器来重建火山喷发序列。第一次爆炸是相对较弱的地震和次声事件。几分钟后发生了一次主要的平流层火山灰注入，并产生了持久的大气和地面耦合声波，次声传感器在11，000公里远的地方检测到，地震仪在2300公里远的地方检测到。12分钟后发生了一次地震事件，地震仪在7000公里外记录到了这一事件。我们估计火山强度约为10.9，将2014年的克卢德火山喷发置于1980年的圣海伦斯火山和1991年的皮纳图博火山喷发强度之间。我们展示了远程次声和地震传感器对于火山爆发的早期检测是如何至关重要的，以及它们如何有助于约束和理解喷发序列。
The February 2014 eruption of Kelud volcano (Indonesia) destroyed most of the instruments near it. We use remote seismic and infrasound sensors to reconstruct the eruptive sequence. The first explosions were relatively weak seismic and infrasound events. A major stratospheric ash injection occurred a few minutes later and produced long‐lasting atmospheric and ground‐coupled acoustic waves that were detected as far as 11,000 km by infrasound sensors and up to 2300 km away on seismometers. A seismic event followed ∼12 minutes later and was recorded 7000 km away by seismometers. We estimate a volcanic intensity around 10.9, placing the 2014 Kelud eruption between the 1980 Mount St. Helens and 1991 Pinatubo eruptions intensities. We demonstrate how remote infrasound and seismic sensors are critical for the early detection of volcanic explosions, and how they can help to constrain and understand eruptive sequences.
