Is thunder dangerous?im really getting scared because its raining hard and thundering,is it dangerous

Thunder is the sonic wave or sonic boom that is created by the rapid heating and expanding of air left by a lightning bolt. Thunder itself is not dangerous. It is was is proceeded that is. Lightning can be very dangerous. Best place to be while it is storming and lightning is indoors. If you can not get indoors, the next best thing is to stay in a vehicle. The vehicle's body acts like a faraday cage. It safely dissipates the lightning strike. Keeping the occupants safe.

Thunder is not dangerous. Lightening is dangerous. If you hear thunder, you were not struck by lightening. If the thunder is close, stay inside. One of the safest places for lightening protection is in a car (do not touch anything metal inside the car).

Thunder is a sound. You see lightning then hear thunder. You can calculate how far lightning is:
