Strictly speaking the answer is "infinite." The smaller the earthquake magnitude, the more frequent they are and the harder they are to detect. There are scads of tiny earthquakes barely big enough to detect, and probably far more that are even smaller.
As a practical matter hardly anybody's going to notice anything smaller than magnitude 4 or so.
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.
Between 2000 and 2012 the average number of earthquakes in just the US was 3,820 per year that are magnitude 2.5 or higher as reported by the U.S. Geological Survey (USGS) National Earthquake Information Center.
The total count is much higher because many go undetected because they hit remote areas or have very small magnitudes.
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.
New Zealand, thus why about 15,000 earthquakes occur every year there
The frequency of earthquakes depends on the location. in Japan, earthquakes occur 3 times a month, and in the Sahara in Africa they occur once in five years..
There's about 140 earthquakes with 6 magnitude or above a year.
It is almost impossible to know because there are earthquakes of different sizes all over the world. It is said that there are earthquakes happening every where every day. Most are so small they did not register on the Richter Scale and many that do are so small they are not worth mentioning as no one notices or feels them. The only ones that get mentioned and recorded with geological survey centers are the ones that register or are significant enough to be felt or have an effect on anything.
Extremely few. Most earthquakes happen in the ocean, or too far below the crust for us to feel them, but hundreds happen every week.
Thousands occur every year, most of which are too small to notice.
On average, there are roughly 20,000 - 30,000 recorded earthquakes every year.The USGS estimates that several million earthquakes occur in the world each year but many go undetected because they hit remote areas or have very small magnitudes.

There are about 10,000 earthquakes every year
It is not fixed.
more than a thousand each year
Between 3000-4000
Lots and lots of earthquakes are happening every day, but many of these are too small, or hit in an unpopulated area, to be counted. However. there are about 70 strong registered earthquakes a year
New Zealand, thus why about 15,000 earthquakes occur every year there
It is impossible to tell. 2010 was a year of numerous large earthquakes around the globe. However, many smaller earthquakes occurred and many more that were too weak to be measured. It is estimated that millions of earthquakes occur each year.
Istaanbul. you'll be surprised to see how many earthquakes hit there every year.....*ohh*
