Sorry to burst everyone's bubble... but if you look at the source video you can see that a large neighborhood loses power. Looks like it is just power lines going down or transformers blowing.

Earthquake P waves travel at roughly 10,000 kph (6,700 mph), and will take about 9 seconds to travel 50 km (30 miles), a typical distance to the horizon.
During an earthquake, transformers may be disrupted over a wide region, and will be seen as precursor lights from regions further from the epicenter. Despite that, they're a human and technological phenomenon, not a natural and geological one.
The cause of course could easily be from the electricity distribution infrastructure, or from some piezo/etc effect from the earth moving - it's likely not presaging the quake itself
