When these pressure waves contact the ground, they push and pull on the surface in a process called air-to-ground coupling that transfers energy into Earth's interior. The energy transfers through a ...

Project Summary: The intent of this study is to define the seismic response of iPVC pipeline systems with couplings and to illustrate procedures for interpreting laboratory results to seismically ...

Atmospheric waves from a massive 2022 South Pacific volcanic eruption created seismic waves that penetrated Earth to at least 5 kilometers in Alaska, creating an opportunity to employ an unusual ...
