Over the last two decades a series of large ring laser gyroscopes have been built having an
unparalleled scale factor. These upscaled devices have improved the sensitivity and stability …

Recent progress in rotational sensor technology has made it possible to directly measure
rotational ground-motion induced by seismic waves. When combined with conventional …

It has been noted by theoretical seismologists for decades that—in addition to translations
and strains—the rotational part of ground motions should also be recorded. It is expected …

Most instruments used in seismological practice to record ground motion are pendulum
seismographs, velocigraphs, or accelerographs. In most cases it is assumed that seismic …

Single-component ring lasers have provided high-resolution observations of Earth's rotation
rate as well as local earthquake-or otherwise-induced rotational ground motions. Here, we …

Recently, due to observations of rotational ground motions, a promising new field of
research in seismology and engineering has developed. However, exploration of rotation's …

The interaction of ocean surface waves produces pressure fluctuations at the seafloor
capable of generating seismic waves in the solid Earth. The accepted mechanism …

Recently, ring laser technology has provided the first consistent observations of rotational
ground motions around a vertical axis induced by earthquakes.“Consistent,” in this context …
