        Can last for about 1 to 2, or even 4 hours
        
        Can be very destructive in nature with their speed ranging from 110 mph to 300 mph
        
        Are most likely to occur between 3 p.m. and 9 p.m., but can occur AT ANY TIME
        
        The fujita scale is a common way of measuring the strength of tornadoes
        
        Most tornadoes spin in the cyclone direction while some spin in the anticyclone direction
- - - - Tsunami waves do not look like normal waves as they do not break and curl as normal waves do
        
        The waves are called a 'wave train'
        
        Waves can be as big as 100 feet (30.48 m)
        
        The intensity of tsunami waves are usually low in deep ocean
        
        About 80% of tsunamis occur in the Pacific Ocean's RING OF FIRE
        
        Tsunamis can travel up to a speed of 500 to 800 km/h

        FORESHOCKS and AFTERSHOCKS are the energy released before and after the earthquake
        
        The earthquake is considered major when is registers 7.0 magnitude scale
        
        90% occur along the RING OF FIRE, in the PACIFIC OCEAN
        
        Around 8000 people die every year due to earthquakes
        
        Most earthquake related injuries result from collapsing walls, flying glasses and falling objects

        Types of avalanches
        
        Wet snow
        
        Can reach speeds of 90 km/h in about 5 seconds
        
        A few seconds after the avalanche, the snow turns into ice, freezing as hard as cement
        
        Kills more than 150 people each year
