EMERGENCY ALARM 

INCREASED CLIMATE TEMPERATURES
NATURAL DISASTER
DISPLACED POPULATIONS

Climate change and rising global temperatures are causing an increase in the number of 

devastating natural disasters. Communities that find themselves in the wake of these 

disasters can be in great danger and usually need to be evacuated to reach safety. 

Warning systems can reduce the destructive impacts of a natural disaster on these 

communities and populations. BELL is a solution that helps even the poorest of regions 

in case of disaster.

  The number of devastating natural disasters has tripled in the past 30 years. 

 
 Populations living in developing countries are also exposed and vulnerable to natural disasters.
 
 These populations often don’t have any alarm systems to keep them safe.
 
An alarm just in time
 
Even with sophisticated technology,
we are not able to predict major natural disasters a long time beforehand.
With BELL, we can warn populations 20 minutes before the natural disaster strikes their area that they need to take cover or evacuate as soon as possible.
