Tornadoes have been happening from the beginning from our planet's birth. Since then we have not been able to record the amount because there were no intelligent human life, no recorded written language, and there were tornadoes in areas with no inhabitants. We do not have the exact number of tornadoes that have occurred on this planet. Yet we do have the number of tornadoes average per year in different countries.
As of September 26 there have been 10 confirmed tornadoes in Pennsylvania in 2012.
That is not known. Official statistics say there are about 2,000 tornadoes in the world per year, but the actual number of tornadoes is probably much higher. Many countries do not keep record of their tornadoes and so only ones that cause major damage become known. Many tornadoes that occur in unpopulated areas go unnoticed.
There have been at least 6,717 confirmed tornadoes in the U.S. in the past 5 years. This number may actually be higher as the figures for April through June of 2011 are still preliminary. Statistics world wide are not available as many countries to not keep records of their tornadoes, but tornadoes, some of them deadly, have occurred in almost all parts of the world and on every continent except Antarctica.
Multiple tornadoes can form at the same time during a severe weather event, especially in outbreaks or supercell thunderstorms. The exact number of tornadoes that can form simultaneously can vary, but it is not uncommon for several tornadoes to be observed in the same area or region at once.
The number of tornadoes in 1900 is not known. Official records for the United States only go back to 1950, and the vast majority of tornadoes were missed. Work by tornado expert Thomas P. Grazulis indicates that there were at least 51 significant tornadoes (F2 or stronger or causing a death) in the U.S. in 1900. However, most tornadoes are not rated as significant, and many F2 tornadoes may still have been missed.
No one could answer that because tornadoes have been destroying the world over before the dinosaurs.
There have been many thousands of tornadoes in the United states. This country averages over 1000 tornadoes every year.
no one will ever know because there was alot in prehistoric times
Tornadoes happen all around the world and it depend on your location as to how many tornadoes you will have.
There have been many F5 tornadoes. See the link below for a list.
There were 102 tornadoes in Oklahoma in 2010.
yes tornadoes and dust devils are common in Africa
1091 tornadoes have been confirmed in Georgia since 1970.
From 2010 to 2011 there were 47 tornadoes in Pennsylvania.
Tornadoes are not a special, divine creation separate from anything else. They have been part of the world since the world took form.
In the years 2000-2010 there have been 13,817 tornadoes confirmed in the United States.
On average, there are about 1,000 tornadoes reported worldwide each year, with the United States experiencing the most. However, many tornadoes likely go unreported in remote regions or over oceans. It is difficult to provide an exact number of all tornadoes globally due to limitations in monitoring and reporting systems.
