A Natural Disaster Alert Alarm is a warning system designed to notify people about an impending natural disaster, such as earthquakes, tsunamis, floods, cyclones, or landslides. These alarms help in early evacuation and preparation, reducing damage and saving lives.

Types of Natural Disaster Alert Alarms
Seismic Alarms (Earthquake Alert Systems) – Detect ground movements and issue early warnings.
Tsunami Warning Alarms – Triggered by underwater earthquakes and water level sensors.
Flood Alert Alarms – Based on rising water levels in rivers or reservoirs.
Cyclone Warning Alarms – Issued by meteorological departments based on wind patterns.
Landslide Warning Systems – Detect ground instability using sensors.
