Indirectly.
My present employer owns an historic grist mill. The mill's current form
dates back to 1872, when it was rebuilt after a fire. The previous
iteration of the mill is noted as a landmark in maps and documents of both
armies during the period of the Battle of Monmouth and predated the
Revolution.

A few years ago, the road and wooden beam bridge over the raceway and dam
were rebuilt by the county due to age and load restrictions. Because of
the proximity of the bridge and road to the mill (just a few feet), and
its status on the the state's historic sites registry as one of the
state's few remaining mills, precautions had to be taken to preserve the
integrity of the mill's structure. Primarily, this included placement of
seismic monitiors in and around the building which were monitored during
the period that the pilings for the bridge were set. Further, instead of
using a pile driver to set the steel pilings, a vibrating device was used
to minimize the seismic impact on the structure.
Happily, there was no damage at all to the structure and a restoration was
completed soon thereafter.

Not sure if this really gets at what you're asking. But it's an example of
how this equipment is used.

Oh, by the way. During the construction period, we had a real, honest to
goodness earthquake that we all thought was just part of the bridge
construction. When we went outside, there was no one working.
I would have loved to have seen the readings on the seismic monitors that
day!
