The National Disaster Management Authority (NDMA)’s Cell Broadcast Alert System (CBAS) has been tested in recent weeks to send out mass alerts when natural disasters strike, but it did not do so.
Meanwhile, Google did not send out alerts in the national capital, even though tremors were felt in both instances here.
What is Cell Broadcast Alert System (CBAS)
CBAS is a public warning system that uses cellular networks to send emergency messages to mobile phones within a specific geographic area.
CBAS messages can be sent regardless of whether the phone is in service or whether the user is subscribed to a particular service provider.
CBAS messages are typically used to warn people of imminent danger, such as severe weather events, natural disasters, or terrorist attacks.
CBAS messages can also be used to provide information about evacuations, road closures, or other important public safety alerts.
CBAS messages are broadcast over a dedicated frequency, which means that they can be received even if the cellular network is congested or unavailable.
CBAS messages are also displayed on the mobile phone screen, even if the phone is locked or turned off.
CBAS is a valuable tool for public safety officials to communicate with the public during emergencies. It can help to save lives and reduce property damage.
Android Earthquake Early Warning system
The Android Earthquake Early Warning system is a free service that detects earthquakes around the world.
It can alert Android users before shaking starts.
It is powered by ShakeAlert®, a system of sensors that detect earthquakes and send alerts to government agencies and other organizations.
The Android Earthquake Early Warning system works by using the sensors in your Android phone to detect ground motion.
The system then analyzes the signals from many phones to determine if an earthquake is happening.
If the system determines that an earthquake is happening, it sends an alert to Android users in the affected area.
The Android Earthquake Early Warning system can provide users with a few seconds to a few minutes of warning before shaking starts.
This warning can be used to take steps to protect yourself, such as dropping, covering, and holding on.
