The situation is apparently quite grim with the broad scale of devastation. I hope technology can help guide and focus resources and rescuers as quickly as possible.
What an awful event.
What kind of infrastructure is in place that would survive to allow network connectivity for people to access socials to ask for help?
Infrastructure is fine.
At least enough of it is. I had no trouble calling people in the area minutes after it happened.
This one. On the previous large quake in the country, the networks collapsed and there was a huge public uproar because the network operators were claiming disaster readiness in their ads, even showing drone swarms flying to the disaster area to provide network services.
Maybe they actually hardened their networks but in general, the internet connectivity seems more resilient as the regular phone calling was restored much later than the internet connectivity last time.
This time there are many tweets and instagram stories of people posting text, selfies and videos from under the rubble, together with their address, their condition and the number of people in the house.
Here are a few examples:

Just a couple of years ago, there was "amnesty" for buildings. My father in-law was bragging how his building, which did not have any inspection or permits during the construction, has gotten amnesty for a small fee and he could sell flats to others now..
Talks of another amnesty days before this earthquake.
