Natural Disasters
Unpredictable forces of nature like tornadoes and hurricanes can have a devastating impact on humans and our environment. Learn how natural disasters work and how science aims to better predict them.
At any moment, magma moving at 100 mph could rumble into the communities at this volcano's base. Scientists predict a massive eruption, but the question is when.
A tornado can turn a house into toothpicks, but when you think about it, it's really just a funnel of air. What's it like on the inside?
Wildfires spread quickly consuming almost everything in their path -- including homes. What can you do if you see the inferno racing toward your home?
What if a plane landed in San Francisco at the same time there was a big earthquake?
San Francisco has a new airport that's supposed to stand up to the rigors of an earthquake. Does that mean that planes can land while a massive quake is shaking the city?
There are obvious craters on Earth (and the moon) that show us a long history of large objects hitting the planet. But what if one hit Earth today?
Earthquakes and their resulting aftershocks can be devastatingly destructive. Earthquakes are caused when a fault in the Earth's crust slips, which releases energy waves in the ground. Find a list of 12 of the most destructive earthquakes in history.
Tornadoes are dangerous things, so it's important for you and your family to be prepared in the event of one. The United States experiences more tornadoes than the rest of the world due to low-lying geography. See our list of 15 tornado safety tips.
While close to 100 tropical storm systems develop each year, often only a handful become hurricanes. Between 80 and 100 of these storms form each year from June to November in the Caribbean. Find 10 destructive hurricanes in recent times.
The Mount St. Helens eruption resulted in almost 60 deaths. Learn more about the Mount St. Helens eruption, from how it happened to the aftereffects.
Learn how avalanches form, how long you can stay alive while buried under an avalanche and what steps you can take to survive.
The wall of water that struck northern Japan on March 11 claimed more than nearly 16,000 lives. While the human and cultural extents of this natural disaster are difficult to grasp, we can explain the physical properties that led to it.
I read 'How Floods Work,' but I still have a question: Why are there so many more floods now? It seems like there are floods all the time, and it didn't used to be that way. Is it raining more?
Flooding has claimed more lives than any other natural disaster. Find out how a gentle stream becomes a raging torrent.
The raging wildfires in southern California have claimed lives and destroyed hundreds of homes. Learn how wildfires start and spread, and find out what firefighters do to battle the blaze.
Is it true that scientists are predicting a really big earthquake will sink western California?
Is it true that scientists are predicting a really big earthquake will sink western California into the ocean, or break it off from the continent?
An earthquake is one of the most terrifying phenomena that nature can dish up. We generally think of the ground we stand on as "rock-solid" and completely stable. An earthquake can shatter that perception instantly, and often with extreme violence.
Volcanoes are some of nature's most awe-inspiring displays, with everything from exploding mountaintops to rivers of lava. Learn how all the different types of volcanoes work.
How often have you watched a weather forecaster point to a spiral-shaped cloudy mass with a sense of dread and fascination? What fuels these ferocious storms?
Why do hurricanes seem to move as if they have a mind of their own, and why do they follow such peculiar tracks?
Hurricanes seem to have a mind of their own as they track across the Atlantic Ocean. While they all follow the same general directions, local weather patterns effect where they ultimately land. Find out why hurricanes move the way they do.
Lightning is an incredible force of nature. And like many natural phenomena, lightning is not always what it seems. Go behind the mystery and learn what's really going on when lightning strikes.
