How Do Tornadoes Form Want to stay on top of all the space news? Follow @universetoday on Twitter Tornado in Kansas How do tornadoes form? The formation of a tornado follows a clear set of steps. Once a tornado has formed, it follows a predictable life cycle. During the next stage the tornado’s main source of energy, the RFD, begins to cool. Lastly, with the tornado’s warm air supply cut, the vortex begins to weaken and shrivel away. We have written many articles about tornado for Universe Today. If you’d like more info on tornado, check out the National Oceanic and Atmospheric Administration Homepage. We’ve also recorded an episode of Astronomy Cast all about planet Earth.

Inside disaster haiti Six weeks after the Haiti shock, Chile was struck by an 8.8-magnitude earthquake. It was 500 times more powerful than the Haiti quake, yet killed less than 1% of the Haitian total. In this section, we explore answers to the question: why was the Haiti earthquake so destructive?

Building Codes “The poverty in Haiti lends itself to people building where they want, how they can … not everybody’s going to be able to build to the exacting standards that a building code requires.” Unlike in other countries located on or near fault lines, very few of Haiti’s buildings were constructed for earthquake resistance.

Tornado Central - US Severe Weather Alerts Prominent severe weather alerts issued by the National Weather Service now viewing Current US Doppler Radar Map Current US Surface Weather Map Current US Infrared Satellite Map US Precipitation Forecast Biggest Tornado Want to stay on top of all the space news? Follow @universetoday on Twitter Determining the biggest tornado can be a tricky endeavor. First of all, there is no direct absolute way to measure the width of a tornado. There is also the fact that a tornado can be ranked by many factors such as wind speed, level of destruction caused, drop in barometric pressure, or the length of travel path. Another problem is that in many cases like in the Tornado Alley of the Midwestern United States, a storm system often produces multiple tornadoes. While there is no definitive method there are some records that can give us a general idea about some of the greatest tornadoes in recorded history. The title of most devastating tornado goes to the Tri-State tornado of 1925. The closest measure to the Biggest tornado would be the widest damage path. As you can see you define the largest tornado by many factors. If you enjoyed this article there are other pieces on Universe Today that you will loved to read.

What is a volcano? Introduction to volcanoes The earth's mountains, plains, plateaus, soils, rocks, etc. as we see it today is believed to have gone through many phases, with about 80% of it being carved out by the action of volcanoes. A volcano is simply a rapture (opening or vent) on the earth's surface (crust) through which molten magma (extremely hot mixture of gases, lava, ash and other burning substances) escape on to the earth's surface. How do Volcanoes look like? In May 1980, the Mountain St. Volcanoes occur at weak zones or points in the earth’s crust (including constructive and destructive boundaries). For history lovers… In A.D. 79 (really long ago) two Roman cities, Pompeii and Herculaneum, were completely buried in ash and dust in a matter of hours after a volcanic eruption. The word, ‘volcano’ was made out of the name of a Roman god of a small island in the Mediterranean sea of Sicily called ‘Volcan’. Now we shall see in a bit more detail how volcanoes come about.

Damaging Air Winds: Kids Guide to Tornadoes | Air Oasis Authored by Dr. Jeff Bennert Windy days can really stir things up and make it difficult to hold on to things that are important, like your umbrella or paper from school. Wind can also be pretty scary too, especially when that wind is a tornado. Known as twisters, tornadoes can tear down a house and can really hurt or even kill people who are in its path. What are Tornadoes? This is the first thing that kids need to know if they want to learn about tornadoes. How are They Formed? Tornadoes are formed because there are certain conditions that are present. Where are Tornadoes Common? In the U.S. there is an area called the Great Plains. When are Tornadoes Most Common? The peak season for tornadoes is from the month of March through the month of May for states in the southern parts of Tornado Alley.

Dangerous Weather Tornadoes are associated with large (supercell) thunderstorms that often grow to over 40,000 feet. A column of warm humid air will begin to rise very quickly. 1. Air Rotates Because of Wind Shear. 2. 3. Natural Disasters - Earth Facts and Information Introduction- What is a natural disaster? The definition of natural disasters is any catastrophic event that is caused by nature or the natural processes of the earth. The severity of a disaster is measured in lives lost, economic loss, and the ability of the population to rebuild. Events that occur in unpopulated areas are not considered disasters. All natural disasters cause loss in some way. Then there is loss of property, which affects people’s living quarters, transportation, livelihood, and means to live. The natural disasters that really affect people worldwide tend to become more intense as the years go on. Scientists, geologists, and storm watchers work hard to predict major disasters and avert as much damage as possible. Flood- Natural disaster However, despite the many natural disasters the world over, mankind has shown amazing resilience. Many people talk about when a disaster has hit and their neighbors and countrymen have come to aid, often to their own loss.
