Hi Timidgal, this thread got me to wondering about the way sound waves and other forms of vibration are propagated through saturated ground vs.
"regular ground". I noticed ever since the hurricane my house is shaking and rattling and rumbling more when heavy trucks go by on a road that runs
a little ways beyond the woods behind my house. Normally we don't get that much road noise this time of year and get more of it in winter when the
trees are bare. But it's been really noticeable since all this rain came. I tried a google search to see if saturated ground conducts vibration
stronger than unsaturated ground does but I only found very technical research documents that were beyond my ability to decipher. There was too much
calculus or some other kind of math I haven't had to wrestle with in 25 years and even though I can sometimes at least wade through technical jargon
fairly well, that wasn't the case for me this time. But I hope in mentioning it, someone who is better educated can chime in. It may be that
somehow with all the rain, you are in an area that can feel the jolt from the normal aftershocks of the Virginia quake. From what I can gather from
the articles I read, the VA quake is acting "normal" and settling down. The aftershocks are supposed to be like this for a once off sizable quake.
My backyard has sunken down in the past year. I don't think it's a sinkhole, though I have seen one very close to my backyard once and had a fist
sized one appear in the yard (and then disappear). This is just an acceleration of continuing normal events in my yard due to how the developers
designed the landscaping to handle drainage in our neighborhood. It's due to heavy snows last winter and hard rains now. At some point we will have
to carefully re grade the back and side yards.
