That is the weirdest thing.
My homemade seismometer just tipped indicating vibration but we felt nothing.
I knew it could not be the wind that tipped it - I thought perhaps an insect had flown into it!
Perhaps it works!!
Felt it down here in Juan Dolio. It was a slow rumble (15-20 seconds?) then right near the end I felt my chair move slightly. I looked at the clock and it was 4:18PM.
