论文摘要
2022年1月15日，在04:14:45（UTC），南太平洋汤加（Hunga tonga-funga Ha'apai）是南太平洋汤加群岛的海底火山，爆发并产生了全球地震，冲击和电磁波，也散发出了日本的日本，该浪潮遍布8,000 km。卡格拉（Kagra）是一个重力浪潮望远镜，位于日本卡米卡（Kamioka）的地下设施中。它具有多种辅助传感器来监测阻碍重力波的观察到的环境干扰。这些环境传感器在地下设施内外都观察到了火山喷发的作用。特别是，冲击波使评估从大气中的气压波到地下环境干扰（气压和地震运动）的传递函数成为可能。
On January 15, 2022, at 04:14:45 (UTC), the Hunga Tonga-Funga Ha'apai, a submarine volcano in the Tongan archipelago in the southern Pacific Ocean, erupted and generated global seismic, shock, and electromagnetic waves, which also reached Japan, situated more than 8,000 km away. KAGRA is a gravitational wave telescope located in an underground facility in Kamioka, Japan. It has a wide variety of auxiliary sensors to monitor environmental disturbances which obstruct observation of gravitational waves. The effects of the volcanic eruption were observed by these environmental sensors both inside and outside of the underground facility. In particular, the shock waves made it possible to evaluate the transfer functions from the air pressure wave in the atmosphere to the underground environmental disturbances (air pressure and seismic motion).
