I just talked to my Aunt and the evacuation is going smoothly, as expected. All Chilean coast is being cleared out and evacuated as of now. The Tsunami Alert is up and will likely be kept like this for another 6 or so hours.
A few minutes before the 7.8, there was another quake of 6,4 and right now on this very second, there has been a set of 5,8 and 5,6. Arica’s power is out and is very probable that Iquique’s power is out too.
If you have any family or friends around this zone, do not try to call them, the lines will be collapsed. Try to contact them through whatsapp or another way through internet because the 3G is still functional in the area.
