Cemaden is the body responsible for monitoring natural disasters in Brazil. The siren system is used to alert populations in geological risk areas.
Lieutenant Colonel Anthony Barrera, from the National Center for Natural Disaster Monitoring and Alerts (Cemaden), explained that now those who live in communities with sirens will also receive an alert on their cell phone indicating the danger:
"The siren rang, the resident will receive the message on their cell phone. It's a little later, in a complementary way, for the person to realize that the system is working and be able to find an escape route and a support point", said the director.
