alot, there is one earthquake somewhere in the world every 30 seconds, even if you cant even feel it.
Many, many thousands. Fortunately most are not powerful enough to be destructive.
earthquake?
That causes some earthquakes, but most earthquakes occur as a result of tectonic plate grinding against each other.
According to the USGS National Earthquake Information Center (NEIC) 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. Approximately 1 earthquake of magnitude 8.0 and higher occurs per year around the world.
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.
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.
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.
There are no specific timings to when any earthquakes occur. They occur when two tectonic plates collide into each other, and that can be any time.
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.
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.
earthquake?
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.
