I would think that in most disasters, your phone won't work anyway.
When we were in Hawaii one summer, a hurricane was approaching. We called the local elder we knew about, and he told us to go to the high school if there was a call to evacuate homes. That is where they would give detailed information.
It fizzled before it could hit the island, but we sure had rain and big waves.
After the big Alaska earthquake in 1964 all the congregations in our area in Washington State had earthquake preparedness parts on the service meetings.
I don't see this thing as a big deal. Maybe it's a kindness even.
