7 earthquakes, one earthquake about every 20 years
The US has about 50 earthquakes every day.
Most parts of the world have small earthquakes every few days, small enough not to be noticed by people in general, only by instruments. Britain is fortunate that it generally has few earthquakes that cause damage, unlike places such as Pakistan and California that have had devastating earthquakes during the last 100 years or so.
Earthquakes are not only in Japan - they happen all over the world. In the last two years there have been notable earthquakes in Japan, China, New Zealand and many other places around the world.
The world cup happens every 4 years.
Around 100-150 earthquakes are recorded every year in the UK. About 15% of these are reported felt. On average an earthquake of magnitude 4.7 or larger occurs every 8 years, while a magnitude 5.0 or larger occurs every 18 years.
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
On average, there are roughly 20,000 - 30,000 recorded earthquakes every year. There were 21,546 recorded earthquakes in 2010 around the world according to the USGS. Note many go undetected because they hit remote areas or have very small magnitudes so the actual numbers are much greater.You can visit the site below to see lists on recorded earthquakes in the year 2010 as well as past years.
It is not fixed.
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
The US Geological Survey estimate that there are approximately 100,000 earthquakes in the world each year that will be felt by humans. Which is approximately 1 every 5 minutes!
