Travellers at Luis Muñoz Marín International Airport were subject to eerie flickering lights as power outages relinquished electricity from large parts of Puerto Rico today (January 7).<br /><br />Footage shows passengers in a dimly lit terminal shortly after the initial 6.6 magnitude quake.<br /><br />The filmer said: "The video starts recording right after the power went out, people looking to be out of place without understanding on what was going on. <br /><br />"Some people got worried while others stayed calm. It ends when it shoots out to the departures section."<br /><br />The island suffered further seismic activity later on in the day as another 6.0 magnitude quake rocked the area.
