摘要
越来越多的地震台站也配备了微型气压计,这增加了人们对地震声学领域的兴趣。对该领域最新进展的回顾可以在Dannemann Dugick等人(2023)中找到。本说明的目的是提请Dannemann Dugick等人(2023)的读者注意固体地球和大气之间的几个额外的相互作用,这些相互作用在地震声学领域中没有被经典地考虑过。2022年1月15日,Hunga Tonga-Hunga Ha 'api火山爆发产生了声波重力波,全球都有记录。例如,这次喷发产生的兰姆波产生了早到达且持续时间长的海啸波。这次喷发还提供了全球记录的大气模式与固体地球模式的耦合,为大气和固体地球之间的边界可能发生的复杂相互作用提供了另一个例子。即使在没有大的大气信号的情况下,地震台站配置的压力传感器也可以成为估计当地子结构的有用工具,例如在VS30,上层30米的平均剪切速度。最后,在低频率下,可以使用压力记录来校正地震仪上记录的大气扰动。我们简要回顾了上述非传统的地震声学主题,我们认为这些主题作为固体地球和大气之间发生的全套相互作用的一部分是重要的。
Comment on “A New Decade in Seismoacoustics (2010–2022)” by Fransiska Dannemann Dugick, Clinton Koch, Elizabeth Berg, Stephen Arrowsmith, and Sarah Albert
ABSTRACT An increase in seismic stations also having microbarographs has led to increased interest in the field of seismoacoustics. A review of the recent advances in this field can be found in Dannemann Dugick et al. (2023). The goal of this note is to draw the attention of the readers of Dannemann Dugick et al. (2023) to several additional interactions between the solid Earth and atmosphere that have not been classically considered in the field of seismoacoustics. The 15 January 2022 Hunga Tonga–Hunga Ha‘api eruption produced acoustic gravity waves that were recorded globally. For example, the Lamb wave from this eruption produced early-arriving and long-lasting tsunami waves. This eruption also provided globally recorded coupling of atmospheric modes with solid Earth modes, providing another example of the complex interactions that can occur at the boundary between the atmosphere and the solid Earth. Even in the absence of large atmospheric signals, collocated pressure sensors at seismic stations can be a useful tool for estimating the local substructure, such at VS30, the average shear velocity of the upper 30 m. Finally, at low frequencies, it is possible to use pressure records to correct out atmospheric disturbances recorded on seismometers. We briefly review the aforementioned, nontraditional seismoacoustic topics that we feel are important to consider as part of the full suite of interactions occurring between the solid Earth and atmosphere.
期刊介绍:
The Bulletin of the Seismological Society of America, commonly referred to as BSSA, (ISSN 0037-1106) is the premier journal of advanced research in earthquake seismology and related disciplines. It first appeared in 1911 and became a bimonthly in 1963. Each issue is composed of scientific papers on the various aspects of seismology, including investigation of specific earthquakes, theoretical and observational studies of seismic waves, inverse methods for determining the structure of the Earth or the dynamics of the earthquake source, seismometry, earthquake hazard and risk estimation, seismotectonics, and earthquake engineering. Special issues focus on important earthquakes or rapidly changing topics in seismology. BSSA is published by the Seismological Society of America.
