Zusammenfassung
The recently reinvigorated field of infrasonics is poised to provide
insight into atmospheric structure and the physics of large atmospheric
phenomena, just as seismology has shed considerable light on the
workings and structure of Earth's solid interior. Although a natural
tool to monitor the atmosphere and shallow Earth for nuclear explosions,
it is becoming increasingly apparent that infrasound also provides
another means to monitor a suite of natural hazards. The frequent
observation of geophysical sources--such as the unsteady sea surface,
volcanoes, and earthquakes--that radiate energy both up into the
atmosphere and down into the liquid or solid Earth and transmission
of energy across Earth's boundaries reminds us that Earth is an interconnected
system. This review details the rich history of the unheard sound
in the atmosphere and the role that infrasonics plays in helping
us understand the Earth system.
