SCIENCE! We got a couple of blaring earthquake alerts on our phones at 8:10 this morning, braced for impact, and felt nothing. It was a 5.6 temblor about an hour north of us, and although news reports said it did some damage up there, we felt nothing.
However, 20 minutes later, Karen noticed that the quake had been detected at our locale after all--not by our puny human senses, but by the grandfather clock by our front door, which stopped at exactly 8:10 a.m. Its pendulum happens to swing north and south, and I imagine a seismic wave rolled down from the north and hit it out of phase at just the right moment to halt it.
We've seen evidence of earthquake waves in our house before, including a pretty big quake that left books on a shelf arranged in a sine wave pattern. I witnessed them myself during the 1989 Loma Prieta quake, when I saw cars bobbing up and down on a blacktop parking lot like boats on an ocean.
Everything is waves, man. Light's a wave, gravity's a wave, atoms are waves, Earth is a wave, I'm a wave, you're a wave. I didn't expect to find myself thinking such deep thoughts when I got up this morning.
