Technology has made it possible to save lots of lives. It is now possible to forecast any major natural disasters. So, people have a chance to save themselves by moving to a safe location or taking precautions. Here are four ways technology can forecast natural calamities.
1. Early Earthquake Warning (EEW) system
Earthquake is a common phenomenon in many countries. EEW is a very advanced warning system that helps to detect earthquakes. This system can detect the magnitude and source of the earthquake. It can then send alerts to public through cell phones. It also sends signals to stop trains, elevators, and computers in a few seconds.
2. DART for tsunami warning
DART is an advanced tsunami warning system. It transmits data collected from a system of seafloor pressure recording packages. It monitors the changes in pressure caused by tsunamis. Warnings are relayed if a tsunami is detected.
3. Warning system for volcanoes
There is a system developed by a British scientist to forecast the eruption of volcanoes. This helps to protect many lives. Miniature helicopters are used to fly into volcano craters and record the emission of gasses. Sulphur dioxide and carbon dioxide indicates the state of the magma deep down. These recordings help to predict the eruption of a volcano.
4. Pan-STARRS for asteroids and comets
It is an advanced digital camera that is used to detect asteroids and a comet which may be in contact with our planet. It can detect stars that are 10 million times fainter than those visible with naked eye.
These technologies now help us to be prepared for disasters. It helps us to save lives and properties. In future, most such devices will be discovered, and we will be able to save more lives.
