Your post reminds me on the Northridge Earthquake. It took place overnight and rangers in the mountains saw the city lights in the L.A. area roll up and down like waves and then the city lights started going out. They didn't understand what was happening until the quake hit where they were located. It was less that 15 seconds likely, but enough time for them to ponder what they were seeing from the mountains.
