It is almost impossible to know because there are earthquakes of different sizes all over the world. It is said that there are earthquakes happening every where every day. Most are so small they did not register on the Richter scale and many that do are so small they are not worth mentioning as no one notices or feels them. The only ones that get mentioned and recorded with geological survey centers are the ones that register or are significant enough to be felt or have an effect on anything.
Every year there are about 100,000 earthquakes that are strong enough to be felt by people, but only a few of these are strong enough to hurt people and cause damage. In addition to these earthquakes, there are about 400,000 more every year that are detected by special instruments that can feel earthquakes that are too weak to be felt by people.
There are many more earthquakes that happen every year around the world than most people know about. There are about 3 million earthquakes that occur every year but most of them are very mild and not felt.
Earthquakes are naturally occurring disasters that keep coming with time.
They range from small to disastrous.
All over the world hundreds of earthquake occur in different regions, many of whom are not kept in records.
So, to say that the number of earthquakes that have occurred till now is not precise and accurate would be the right answer.
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. Only a portion of these are recorded (~20 - 30K per year) because most occur over remote areas or in the ocean or have very small magnitudes.
For the list of the earthquakes on any given day you can see the USGS website for a list of recent earthquakes.
My answer for how many earthquakes have there been around the world as 3,092 times as to Haiti,El Salvador, Houndoras,Cuba and so on.
The largest in recorded history was a 9.5 earthquake in Chile.
The Strength and Frequency Method only predicts how often an earthquake of a particular magnitude will occur. The Gap Hypothesis only predicts where another earthquake is most likely to occur along a fault line. Neither method will predict where the next earthquake will occur in the world, or predict an earthquake happening in a random spot, or predict both the location and strength of an earthquake.

Frequency is how often something happens.
The most famous Earthquake is the Haiti Earthquake. That would partly depend on where you lived. To people in Lisbon, the most famous earthquake would be that which destroyed that Portuguese city in the early 1700s.
is a small earthquake that often precedes a major earthquake
These smaller earthquakes are called aftershocks. Aftershocks can often be as strong as the earthquake its self and there can be many.
Is a small earthquake that often precedes a major earthquake.
No. It is impossible for an earthquake to blow up the world...
The largest earthquake in the world was the 1960 Voldivic earthquake. It was the most powerful earthquake ever recorded. It rated 9.5 on the magnitude scale. It occurred in the afternoon.
An aftershock is a small earthquake that follows the main earthquake, while a foreshock is a small earthquake that often precedes, leads to, a major earthquake.
An earthquake can often disrupt water mains or interfere with the water table.

No. The earthquake that caused the Tsunami in Indonesia in 2004 was a bigger earthquake than the one that hit Japan.
