alot, there is one earthquake somewhere in the world every 30 seconds, even if you cant even feel it.
When tectonic plates move and grind against each other, this is an earthquake. If the moving of tectonic plates were to occur beneath the ocean's surface, the result would be a tsunami.
There are earthquakes each and every day somewhere on Earth.According to the USGS National Earthquake Information 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 or one every 24 seconds somewhere in the world. Only a portion of these are recorded (~20 - 30K per year) because most occur over remote areas or in the ocean.On average only one of those earthquakes is magnitude 8 or higher each year.To see a list of most recent (or historic) earthquakes visit the National Earthquake Information Center (NEIC) website.

Only a portion of these are recorded (~20 - 30K per year) because most occur over remote areas or in the ocean. Approximately 1 earthquake of magnitude 8.0 and higher occurs per year around the world.
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 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.
An earthquake will most likely occur because the techtonic plates below the earth's surface are grinding past one another causing severe shaking.
About 300 or so measurable earthquakes occur around the world each day. So far, it is not possible to predict the time when an earthquake will occur. The best scientists can do is predict the frequency (once in how many years) an earthquake of a specific intensity will occur on a given fault line.
plates of the earth crash into each other along faults causing an earthquake
the 2 plates that go around the world are rubbing against each other trying to go past and that makes an earthquake
two tectonic plates floating into each other.
On average, there are roughly 20,000 - 30,000 recorded earthquakes around the world every year.The USGS National Earthquake Information Center 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.To see a list of more recent (or historic) earthquakes, visit the USGS Earthquake Hazards Program.
Most earthquakes occur where the edges of Earth's plates are.
Earthquakes occur frequently along the edges of fault lines. This is caused when two plates collide into or slide past each other. This will send shockwaves around the epicenter, resulting in an earthquake.
Two tectonic plates movoin apart, together or under each other
Somewhere around the world there is probably at least one earthquake each day if not more. The U.S. Geological Survey (USGS) National Earthquake Center keeps track of earthquakes around the world. According to the USGS 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. For the latest refer to the list USGS keeps for recent earthquakes world-wide for last 7 days in related links section below. USGS also provides a real-time KML feed. There are also lists for historic earthquakes by year or region.

There is a network of seismometers (earth-quake detectors) setup around the world. When an earthquake occurs it releases a set of powerful waves which travel through the Earth and are detected by the seismometers. By comparing the time taken to reach each seismometer the epicentre of the earthquake can be triangulated.
When two plates slide past each other, this is called a transform fault. Earthquakes can occur when the plates scrape by. If the earthquake happens underwater, a tsunami may occur. (Like in Japan)
