when the weather is being wrong we prepare for our work. primarily we announce a signal to the people.who don't understand there hazard. we also share with them to go the safe shelter. it is a common matter but the people don't came back early there own shelter.only we can reduce there destroy. for re-construction we need help .also we have a poor system to announce the signal. we use our mosque mice and a container or flute we use a sound for awareness .
