Walking along the break-water on a stormy day... I could barely walk because the wind was so powerful and the sea was so fierce it came over the top of the break-water soaking everyone! Edit: David reminded me of something else. Niagara falls, that is an awesome display of natures power. http://images.google.co.uk/images?q=niagara%20falls

Victoria Falls in the rainy season. You can see the spray for miles and hear the thundering water for hundreds of metres.

A flood, I've seen a full size truck towing (or floating) a fifth wheel floating down what used to be a creek. Cows floating away, trees piling up against bridges so eventually the bridge gives in to the pressure and crumbles. Houses in 5 feet of water and entire roads just disapperead.

The Northern Lights in Alaska,the most colorful,breath-taking thing I have ever seen. I have also seen them in Montana,they were not colored just kind of white,but moving around the sky,was so beautiful.

I was swimming in the ocean one day on vacation at Virginia Beach, and I was standing on the sandbar about 300 feet off the shore. The high tide suddenly came in and I was being surrounded by water, and it was getting deeper and deeper, and the waves were getting huge. That was one of the scariest moments of my life. I was only like 10, so it was really freaky.

Angel Falls Venezuela. is pretty impressive A Hurricane is pretty nasty I was in Turkey when they had an Earthquake but it was up north and I was in the south at the time so was not badly affected

For enjoyment it would be the geysers in Yellowstone, but for having "been in" it would have to be playing with my sons in the Pecos River when a sudden and powerful flash flood came through carrying trees and debris. Getting two boys out of a suddenly swollen and dangerous river is a display of Nature I will never forget.

A tornado. It sounded like a freight train and my curiosity got the best of me so I swung open the front door as my grill went flying by. My husband grabbed me and shut the door and proceeded to curse my stupidity but it was really wild. It tore the roof off the apartment building next to ours. I've been in several hurricains in Florida too but no real direct hits.

That would have to be the Aurora Borealis. I also came a lot closer to a tornado once than I wanted to be.

Hurricane in Ocean City, Maryland. Tore up the boardwalk...while I was on it.

The Ocean....the force and magnitude of the currents is amazing!

A bolt of lightning struck a tree less than 15 feet from me. The deafening sound is something I will never forget. The tingling feeling...wow. I ended up on my knees on the ground, with my nose on my knees, and my hands over my head. When I heard the tree cracking as if it were going to fall, I found a running speed that I have never achieved before or since.

LIGHTNING. I watched lightning "blast " a tree on my grandmothers farm. It was as if someone filled the tree with explosives and it went off. The tree shattered into thousands of jagged chunks of wood, some driven into the ground 3 or 4 foot deep some stabbed into nearby trees like a knife. anyone close to this when it happened would have been stabbed to death by wooden spears It was awsom and scary!

hurricaine fredric hit biloxi/gulfport when I was a little girl I was inside alone dad and mom were securing the horses and the trailor we were staying in flipped over with me inside.

The Jarrell Tornado of The Central Texas tornado outbreak was an unusual tornado outbreak in central Texas which occurred on May 27, 1997. The F5 tornado that struck the town of Jarrell, Texas killed 27 people out of 131 residents, making it the second deadliest tornado of the 1990s. The tornado was 3/4 of a mile (1.2 km) wide and tracked across the ground for 7.6 miles (12.2 km). Double Creek Estates, a subdivision of Jarrell, was literally wiped off the map with all 38 homes and several mobile homes destroyed. It ended where I was in Cedar Park, where it split an Albertson's grocery store in two and thru a vintage steam locomotive and it's cars off their tracks. A few days after Jarrell struck, we took a drive to observe the devastation, most of the area was cornored off but you could see the concrete pads where once stood the brick and stone homes of the Jarrell neighborhood, the pads where wiped clean, on most, not one brick remained fastened to it's foundation. No one in the neighborhood survived as far as I know. Many where just children who just got home from school. It was the most devasting tornado I have ever seen. http://en.wikipedia.org/wiki/Jarrell_Tornado http://images.google.com/imgres?imgurl=http://www.traddstormchasingtours.com/jarrell03.jpg&imgrefurl=http://www.traddstormchasingtours.com/lecture.html&h=140&w=220&sz=14&hl=en&start=8&tbnid=BgOGABlO8hpoVM:&tbnh=68&tbnw=107&prev=/images%3Fq%3DJarrell%2BTornado%26svnum%3D10%26hl%3Den%26sa%3DN http://www.spc.noaa.gov/coolimg/jarrell/index.html http://www.met.tamu.edu/research/texacal/outbreak.html This is the best example of what I can give of what I saw; http://www.rogersadler.com/Jarrel_tornado/jarrell.htm http://www.youtube.com/watch?v=k-K-bj8YhiQ These are acutual photo's of the F5 Jarrell Tornado, the base is more than a few miles across, behind the Taco Bell you can see debris from the Albertson's grocery store in the air. It literally split the store in half. This is what I saw.

How a flower can come up through concrete!

When all of those hurricanes ( Jeanne, Ivan, Frances & Charley) hit us a few years back (2004).. not enough words to express the tragedies or damage.

An F4 Tornado. Very scary and tremendous damage.

Niagara Falls. Standing near it is deafening. You can feel the wind created by its flow. It dwarfs everything around it.

There have been a couple. Once, lightning practically blew up a tree just outside my bedroom window. The force of the noise it made shook the windows in my house and knocked me off my bed. Two years ago, the town I live in god inundated with water from a burst dam. I've never seen anything like the aftermath. People actually died. Whole houses were absolutely decimated and swept downstream. The town's center was filled with the debris from the shattered structures. Most of the main road going into town was destroyed and had to be re-routed, because where it used to be, there's now a river. There's a house that stands on the side of the road, alone, and serves as a constant reminder to all who pass through: something tragic happened here. It's a big, ornate house with turrets. Water blasted through this particular house, leaving a gigantic hole in the side of the building, and it's the first thing you see as you're approaching town.

Two actually. One was a lightning strike on a transformer 50 feet from me (your hair does stand up) and the other would be a force 11 east of Sable Island in the Atlantic.

When I lived in California I was in an earthquake that measured 5.9. I think it was in the fall of 1985. I was not familiar with earthquakes. I was familiar with tornadoes. I had an aquarium and the water sloshed, the window frames popped, and the light fixtures swung back and forth. After it was all over I thought it was exciting. I called my mother in Oklahoma and told her what happened and how exciting it was. She said earthquakes were extremely dangerous. I said we have tornadoes in Oklahoma. She said yes we do, but you can protect yourself in a tornado, you can't get away from an earthquake. I had not thought about that. LOL

I'm the most awesome display of power period -That I have personally witnessed. Even nature is jealous.

Multiple funnel clouds hanging down from the sky while driving home from work on the expressway. They would descend and then get sucked back up toward the sky. I kept waiting for one to touch down and be faced with the out-run or ditch dive decision.

The floods we had in NH about a year and a half ago. New Orleans got all the press 'cuz they have more people in that city than we have in our whole state, but that still doesn't mean that we didn't lose people, houses, roads, etcetera. I drove home in it, encountered many washouts, and woke up to discover that every road we had traveled on was GONE, including the end of our driveway, and we were trapped at home in the woods for a couple of days. We couldn't even walk the mile to the store. To this day, Alstead still looks like a disaster... and I drove through it in my little Honda.

Microburst... It almost leveled our town in almost an instant.

See my answer to snow and thunder at: http://www.answerbag.com/q_view/130847 I also would rank very highly, in a slightly different phenomenon the line of three tornados I saw many summers ago in the late 1970s (I can't remember the exact year anymore, only the sight and sounds.) There was a tornado warning issued by the National Weather Service for an area to the west of the radio station I was employed at the time. The staff on duty and I stepped out the door to watch a line of three tornados traveling from south to north over farmland just a few miles away from us. It was strange, in that the sun was out over us, but the wall cloud and thunderhead was just moving in over the clear sky about to obscure the sunshine for us. We saw the lightning bolts and heard distant thunder and the roar of the tornados and sunshine all at the same time. It was breath taking and very frightening in the same take! After the storm had passed. The boss and I drove west and found one of the farms that had been destroyed. The farmhouse had been moved slightly off it's basement foundation, windows blown out and roof taken off. The garage was completely gone, but there was a shiny flawless new Oldsmobile Cutlass balancing on top of a riding style lawn mower. We spotted other damaged farms but that one with the perfect car still remains vivid in my memory.

It is a mixed feeling for me. The most powerful beautiful amazing display of nature Ive seen.. was in a boat "maidens of the mist" at the bottom of Niagra Falls. You can hear and see the spray for miles before you get to it. I have always felt the power of God when at the Gulf of Mexico... but this was SO much more powerful. I guess I'm one of those silly christians because It was like I could feel God standing there beside me, while I was in the falls. Then the other thing that is mixed in with the most awesome display of natures power....was hurricane Katrina. Sad... destructive force...out of control power. Magnificent movement of nature.

A huge lightning storm just above the hill near to where I live, which unfortunatly created floating lightning balls that passed through my computer.

I was living in Florida when hurricane Andrew came through.It blew part of the roof of the the house I was living in.It bent massive hotel signs into parked cars.The water level from the gulf rose.It downed palm trees,for their roots are shallow.

I've been in several hurricanes and two tornados. One of the tornados was during one of the hurricanes.

ok, just wondering.

In a friend's yard in Auburndale Florida, after Hurricane Charlie raged through, we found a little cluster of pine needles that had been thrust into the trunk of an oak tree. They were firmly embedded, and gave us all a spinal shiver with the realization of the power of that storm.

Mt. St. Helens may 18th 1980 I was just a young girl but it was the most life consuming thing I ever personally witnessed.

Great question! hmmm... I would say the Halloween Blizzard that happened in Minnesota when I was about 10. It was unbelievable, so much snow in so little time, plus I got the next few days off of school which is always nice

Hurricane Charlie i was on holiday in Florida at the time,frightening and wonderful at the same time,living in the UK we dont see this very often well never.

A TIDAL AFTER THE ALASKAN EARTHQUAKE.IT CAME AT WELL OVER 100 MPH HIT AND SEEM TO LEAVE WITHOUT WARNING AND LEFT AN AFTERMATH EQUIVILANT TO A NUCLEAR BOMB.

I was in an earthquake in Greece... it was 6.4 on the richter scale but luckily its epicentre was 6 miles off shore... it was incredible though... it woke me up and I knew everything was shuddering violently but it was hard to perceive because everything was shuddering together at the same rate... It's hard to descibe, I felt the motion but couldn't quite see it.. The whole villa was shaking so incredibly... overall a few of the local little huts collapsed but anything with decent foundations was ok. It was just so strange but so very scary at the time. x

Good question. I'd have to say it was years ago, in the Mojave desert when in the army. We were testing stuff, and had to dig a trench. A massive dust devil (desert version of a tornado) swept in and hit the trench we were digging. Watching people picked up about 20 feet off the ground and tossed to the side like they were dolls was pretty spooky. I ran out of the way before I got hit. About 20 guys were tossed by it, but no one was seriously hurt. Cuts and such, but that was it.

I grew up in the suburbs of Texas and haven't traveled much, so the first time I saw a mountain in Oregon (when I was in high school) I stood in awe. I just kept thinking, "This is an ACTUAL mountain - not a picture, but a MOUNTAIN."

An erupting volcano..it's a very scary sight. I forgot the exact date but it was in 1991 I think when Mt. Pinatubo erupted here in the Philippines, the entire Luzon experienced midnight in the middle of the day.
