Title: Sound of an earthquake
Post by: pwhodges on 04 Jul 2012, 05:04
For those of us who have never experienced an earthquake, here is a clip from an organ recording that was being made in a wooden church in New Zealand when a 7.0 quake occurred about 100 miles away:

Proof that playing the organ causes earthquakes... Post hoc ergo propter hoc...  :-D

I went to California for a conference earlier this year, and surprisingly there were no earthquakes. I have experienced earthquakes in Oklahoma, though. The first one felt like the strip mine blasting that I grew up around in the Appalachians. The biggest one (http://en.wikipedia.org/wiki/2011_Oklahoma_earthquake), a 5.6, was large enough to cause part of the ceiling in the room in the university's physics building where its pendulum is to collapse, knocking the pendulum off its tether.

I lived in California for three years and experienced only one earthquake :(

The rocket launches caused more (and more impressive) ground tremors.

I've lived in California on and off for half my life, and the only time I've ever experienced an earthquake was when I lived in Albania.

It's weird waking up in the middle of the night to your bed shaking, thinking it's just the cat scratching herself, and then you snap to full consciousness with the realization that your cat's been dead 5 years.

That's similar to how I felt here. "Oh, it's just the strip mine blasting. Oh, wait, there are no strip mines here."

My place rocked and rolled during that quake, and I live in Wellington, so it was quite strong

The recording must have been made using directional mics (presumably coincidental), because the low frequency components of the quake are recorded very much more strongly in one channel than the other; if we knew the orientation of the mics, we'd know the direction of the earth movements.

We had an earthquake when I was in Greece with my family in 2001 I think.
Sounded like this.. like underground thunder and crashing trees.

The sea was all brown and stirred up for days.

hah. This must be it
