earthquake lights
They are known as “earthquake lights” and have been documented since the 1600s, says a report by the Seismological Association of the United States, as documented by the BBC.
Two days before the 1906 San Francisco earthquake, for example, a couple saw streaks of light along the ground. And in the case of Quebec, Canada, in 1988, a brilliant globe of pink and purple light was seen 11 days before the devastating tremor.
Lights in the sky
This Thursday, this is how the residents of CDMX captured the earthquake and the lights in the sky.
