Data from the past 100 years suggests that the number of earthquakes per year arranged by magnitude is:
Magnitude : Average Number Annually
8 and higher:1
7 - 7 : 9 to 15
6 - 6.9 : 134
5 - 5.9 : 1319
4 - 4.9 : 13,000
3 - 3.9 : 130,000
2 - 2.9 : 1,300,000
The total number is therefore around 1, 500, 000 a year. Given that the Earth is about 4.5 billion years old and solid enough for earthquakes for about 4 billion of that number, the total number of earthquakes in the Earth's history would be about 6x1015 or 6,000 trillion.
Greece sits on the border of two tectonic plates, the Eurasian and the African plate. The Eurasian plate is sliding under the African plate at a rate of around 3cm per year, which results in earthquakes. Since 1900, there have been 7,352 earthquakes in Greece.
Christchurch, New Zealand has experienced significant earthquakes in the past, particularly the devastating earthquake in 2011. However, seismic activity has decreased since then, and the city is not currently as prone to frequent earthquakes as it was in the aftermath of the 2011 event.
Earthquakes have been occurring for millions of years due to the movement of tectonic plates in the Earth's crust. The specific start date of earthquakes cannot be pinpointed as they have been a natural occurrence throughout geological history.
False. While studies on earthquakes can improve our understanding of the Earth's dynamics and mechanisms that cause earthquakes, accurately predicting when and where earthquakes will occur is currently not possible. Earthquakes are complex natural events with many variables at play, making accurate predictions challenging.
Greece experiences many earthquakes each year, ranging from small tremors to larger, more destructive ones. The frequency of earthquakes varies throughout different regions of the country.

It is estimated that there have been around 6.4 million earthquakes in the 2000 years since the birth of Jesus, based on scientific record-keeping. These earthquakes vary in magnitude and impact, occurring all around the world due to the shifting of tectonic plates.

not enough money for schools since there were so many earthquakes.
Too many to count unless you specify a minimum Richter Magnitude!
There are earthquakes almost everyday, some have small magnitudes, you can barely feel them.
Since 1900, earthquakes have occurred in 39 U.S. states. Minor earthquakes, for instance, struck states such as Illinois and Nevada in 2008. There has not been a major quake on the U.S. mainland, however, since the 6.7 magnitude Northridge, California, event in January 1994.

Yes many earthquakes are destructive
Mexico is located in a seismically active region. On average, Mexico experiences thousands of earthquakes each year, but most are small and go unnoticed by people. However, Mexico does occasionally experience larger, more damaging earthquakes.
Nobody knows how many earthquakes can happen in a year because you cannot predict earthquakes. :)
