In 2011, 553 people died from a tornado, according to the statistics provided by the NOAA. So what is so destructive about these swirling cylinders? How do they even form in the first place? Tornadoes are a cone-shaped collection of destructive air that expands downward from a cloud and onto the earths surface.
They are often a product of a thunderstorm cloud. This unique weather condition requires several factors for it to form. First, low moisture is needed. Secondly, something has to pull the air up, from off the ground. Weather.com describes this as "trigger". Once the air has been completely absorbed, it will rise, and depending on atmospheric conditions, form a thunderstorm cloud. This atmospheric conditions includes no stability, with rapid temperature decreases. With these factors present, a tornado is likely to form.

These on the other hand, cause far less destruction or damage. Waterspouts begin to form over ocean waters; however it actually contains freshwater inside its funnel. These usually begin to disperse once they hit land. Other types of tornadoes include firewhirls, gustnados, and dust devils.
So how do we take caution for these dangerous funnels? It’s important for one to know the signs of a potential tornado. When a tornado is about to occur, large hail may fall and the sky might be clouded with dark clouds that will sometimes display a greenish color. One may also notice funnel shaped clouds or loud noises that project a roaring sound. Watching for tornado signs along with being aware of community safety procedures can help prepare one for this dangerous weather condition. When a tornado is present, one should immediately go to a basement or an inner room that contains no windows. An underground room is always safest, however if none are available, going to the lowest and most stable room is always the best substitute. If one is outside while a tornado is taking place, it is best for them to get to the nearest car, shelter, or stable room immediately. These are all important cautions to take when tornadoes strike and if followed appropriately, could save lives.
Another destructive natural disaster is an earthquake. An earthquake is an abrupt and forceful shaking of the ground due to a shift amongst the earth’s crust. These can get to be very damaging, as they vibrate the surface that humans live among.
Earthquakes form when the earth's tectonic plates, sometimes called an underground rock, break along a fault. Understanding what a fault is can help provide a better understanding of what is happening in the earth's crust. The fault is the crack or slit between the two blocks of earth that have broken. It's the parallel structure of one side of the broken plate to the other. Amongst these broken plates, we can identify two walls, the hanging wall and the foot wall. The hanging is wall is the one that has extended over the other, where as the foot wall is the one beneath it. When these two plates rub against each other, trying to "fix themselves" it causes to vibration in the earth's surface.
