I lived in a city with an ongoing sequence of serious earthquakes when my daughter was around 13, so I understand where you are coming from.
However, and I genuinely mean this in a compassionate way, it is not fair to unnecessarily clip our children's wings because of our fears.
To me, the best thing we can do, is let them extend themselves in an age appropriate manner, giving them the tools to manage situations for themselves.
Having the location app is a godsend - we didn't have that at the time! Making an agreement as to what time is a hard stop for time to be home, making sure that she calls you before going out, letting you know where she's going, who she is with, when she will be back.
Discussing with her scenarios such as unwelcome approaches and what to do in that instance.
Also, no matter where we were, or what we were doing, we made sure she knew that in an emergency, she could call, no questions asked, and we would stop what we were doing, and go and get her. If someone was closer, we would call them, to go and get her and we would get to them as soon as we could.
I also made sure that they knew this kind of trust and freedom at this age, was a privilege, not a right, and if they abused it by not abiding by the rules, or by getting into trouble, or up to mischief, it would be smartly, and severely, removed.
