The earth's crust is divided up into large sections called tectonic plates. The plates slowly grind past each other, which often builds up tension. When this tension is released earthquakes are the result. For this reason nearly all major earthquakes happen at the boundaries between plates.
because pressure builds up in these places
Yes. Earthquakes of SOME intensity happen SOMEWHERE every day. There were 2 strong earthquakes today, one in Italy, one in Tonga. The running tally for 26 October 2016 from earthquaketrack.com:99 earthquakes today681 earthquakes in the past 7 days3,156 earthquakes in the past month41,088 earthquakes in the past year
According to GeoNet, around 20,000 earthquakes happen in and around New Zealand each year. Fortunately, only around 250 of those are strong enough to be felt.
Yes, earthquakes can happen underwater. When an earthquake occurs beneath the ocean, it can cause a tsunami if the magnitude is strong enough to displace a significant amount of water. Underwater earthquakes are monitored by seismologists to assess the potential risk of tsunamis.
Some places are heavily affected by earthquakes because they sit on or near a fault line. Christchurch, for example, sits near a fault line and is why it has frequent and strong earthquakes but practically everywhere in Australia is nowhere near a fault line so we get very littleearthquakes.
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
Not everyone, no. Earthquakes happen in certain areas and only those areas will feel it. Of course it depends on how strong the earthquake is.
On average, Haiti experiences around 200 small earthquakes each year. However, these are generally minor tremors and not typically strong enough to cause significant damage.
This year in 2011 probably has the most earthquakes ever.

Japan it gets very strong earthquakes and may cause a tsunami
On average, there are around 500,000 earthquakes a year globally, but the majority of them are too small to be felt. It's estimated that about 100,000 of these earthquakes can be felt by people, with around 100-150 being strong enough to cause damage. The number of earthquakes per year can vary due to various factors.
