If you want the most balanced option to start with, I recommend:
"Defesa Civil Alerta from Defesa Civil Nacional."
I picked this because It is the most efficient disaster warning system in Brazil because it works without an internet connection and bypasses the need for manual registration to save lives in real-time.
