According to the US Geological Survey there are approximately 1,000,000 earthquakes around the world every year (although the vast majority of these are so small they can only be detected by sensitive scientific equipment).
Of these 1,000,000, approximately 1/10 are large enough to be felt by humans. This means that on any day there will be on average 275 earthquakes around the world that can be felt.
Perhaps even more surprisingly, on average there are around 100 earthquakes a year that are large enough to cause damage (however they often don't because they occur away from inhabited areas). This means there is a little under a 1 in 3 chance of there being a "large" earthquake on any given day.
The British Geological Survey have published some data on the annual average frequency of earthquakes of varying magnitudes:
Description : Magnitude : Frequency per year
Great : > = 8.0: 1
Major : 7.0 - 7.9: 17
Strong : 6.0 - 6.9 : 134
Moderate : 5.0 - 5.9 : 1319
Light : 4.0 - 4.9 : 13,000 (estimated)
Minor: 3.0 - 3.9 : 130,000 (estimated)
Very minor : 2.0 - 2.9: 1,300,000 (estimated)

∙ 10y agoIt 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 annually.
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.

∙ 7y agoThe 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 magnitude 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.

∙ 12y agoCalculating the number of earthquakes in one year is a hard process because numerous earthquake happen each day around the world without anyone realizing it. Thousands of earthquakes that vary in size happen each year.

∙ 9y agoOn average, there are roughly 20,000 - 30,000recorded earthquakes worldwide every year by the U.S. Geological Survey (USGS) National Earthquake Information Center.
On average only one of those earthquakes is 8 or higher each year.
However, the USGS estimates that several million earthquakes occur in the world each year and go undetected because they hit remote areas or have very small magnitudes.

There are about 10,000 earthquakes every year
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
Earthquakes are not a seasonal phenomenon and so the time of year has no effect on the occurrence of earthquakes. As such, earthquakes can happen at any time of the year as they occur independent of weather and climate.
On average, 102 occur per day, with 37,283 occurring per year.
once a year
Thousands occur every year, most of which are too small to notice.

It is not fixed.

more than a thousand each 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*
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..
