How many earthquakes occur every year in the us?
According to the United States Geological Survey, more than 3 million earthquakes happen each year. That's one earthquake every 11 seconds! Obviously, many of these earthquakes have little or no effect on human civilization - most are too weak to notice, and many others occur in completely uninhabited places, where there is no one around to feel them. However, every year, at least a handful of earthquakes occur in populated areas and cause death and destruction.

Answer About 40,000 babies are born in the U.S. each year with CMV. CMV is the second leading cause of mental retardation, after down's syndrome.
Earthquakes occur when pressure builds up between 2 masses of rock in the earths crust, where there is a crack between them. Eventually the pressure is released and one piece …of the rock slides upwards. This causes P waves and S waves, which shake the buildings etc.. on the earth's surface. However, they can often be felt in other continents, depending on how bad the earthquake is. For example, the boxing day tsunami earthquake could be felt all over the world, but not as obviously as that in the country it occurred in.
It is impossible to tell the number of earthquakes per year, as many earthquakes occur that are too small to be detected. It is estimated that millions of earthquakes happen a…nnually. Additionally According to the U.S. Geological Survey (USGS) National Earthquake Center there are over a million earthquakes each year around the world -- that's on average 3,561 per day or 2.5 per minute. Only a portion of these are recorded (~20 - 30K per year) because most occur over remote areas or in the ocean.
More than one million a year, but many of these are too minor to be felt.
"According to data from the U.S. Department of Transportation, about 140,215,987,089 fatal and non-fatal truck accidents occur every year, which causes approximately 89,000 in…juries and 5,000 fatalities throughout the country." Source: http://www.truckaccidentlawyergroup.com/
there are over 3 million earthquakes every year
Thousands occur every year, most of which are too small to notice.
There are always little earthquakes that are not noticed, but all the equipment does. Its a very large number, but people only pay attention to the major earthquakes.
Deaths in general? Too many to keep track of.
The US Geological Survey estimate that there are several million earthquakes each year, but the vast majority of these will not be detected because they are too small in magni…tude to detect or are larger, but occur to far away from a seismometer station. From this number, they estimate that there are 500,000 detectable earthquakes in the world each year. 100,000 of these will be felt by humans and 100 of them will be large enough to cause damage. Based on the above, there would be an earthquake of a magnitude that could be detected by seismometers once every 60 seconds, one detectable by humans approximately every 5 minutes and one that does some damage (assuming they occurred near a populated and developed area) every 3-4 days. 20,000 earthquakes in the earth each year.
According to the Center for Disease Control and Prevention, there are over 16,000 homicides each year in the United States. At least 11,000 of those deaths are firearm rel…ated.
On an average their is about 5 earthquakes a week in China. Because of all the population in this country. They may not be of a high magnitude but are also dangerous. Most… more than 5.0
The United States averages about 1200 tornadoes each year. Worldwide the number is less certain.
Earhtquakes can happen any time, any where. There is never a set date.
