It appears we are talking about .0001Hz to a few Hz. So, a MKH-110 could
dabble in the high frequency part of this range. The MKH-110 varient
that goes to 0.1Hz would be the better choice, but it would look like a
place where a homebuilt might do even better. Particularly as most of
the natural events seem to be lower frequency than 0.1Hz. There seem to
be some links around about how to build your own Microbarograph. Here's one:
