Seismic attenuation and the associated quality factor (Q) have long been studied in various
sub-disciplines of seismology, ranging from observational and engineering seismology to …

Seismic hazard studies provide indicators of seismic motion that are expressed for “free‐
field,” that is, representative of the ground motion exactly at the free surface, without …

Ambient seismic noise, particularly useful in urban areas, contains valuable information on
seismic wave attenuation and the related shear-wave quality factor (QS) in the near-surface …

Seismic wave attenuation and the related shear‐wave quality factor (QS) in the near surface
are crucial parameters for ground motion simulations and seismic hazard assessments …

Borehole accelerometers are designed to record strong ground movements at depth. They
have become an important complement to surface accelerometers for seismic and …

This paper presents numerical quantification of depth-dependent free surface effect on
ground motion characteristics for the earthquake-resistant design of underground structures …

The Groningen gas field located in the northern Netherlands is the largest gas field in
Europe. Many induced earthquakes have occurred since the gas extraction commenced in …

This paper summarizes the newly research achievements of the underground seismic
observation networks and borehole vertical seismic arrays in China, and looks forward to the …

目前我国约有数百个井下地震观测台. 井下观测可以避免地表噪声干扰和场地效应,
