Earthquakes occur when pressure builds up between 2 masses of rock in the earths crust, where there is a crack between them. Eventually the pressure is released and one piece of the rock slides upwards. This causes P waves and S waves, which shake the buildings etc.. on the earth's surface.
However, they can often be felt in other continents, depending on how bad the earthquake is. For example, the boxing day tsunami earthquake could be felt all over the world, but not as obviously as that in the country it occurred in.
What else can I help you with?
What biome do earthquakes occur in?
The lithosphere is where earthquakes occur.
Can tornadoes occur in Africa?
Yes, tornadoes occur on every continent except Antarctica.
Has an earthquake ever occurred in the middle of a continent?
Yes, earthquakes can occur in the middle of continents. These are known as intraplate earthquakes and can be caused by geological faults or weaknesses within the continental crust. While less common than earthquakes along plate boundaries, intraplate earthquakes can still occur in areas far from tectonic plate boundaries.
Can earthquakes occur in Sydney?
There were at least 13 minor earthquakes in or near Sydney in the last 10 years. The magnitude of these 13 earthquakes ranged from 1.6 to 2.5. Earthquakes can occur in almost every part of Australia but occur much less often than along tectonic plates north and east of Australia.
Do many earthquakes occur?
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.
Has Antarctica ever had an earthquake?
Antarctica is the quietest continent in terms of earthquakes. Earthquakes have occurred, but are infrequent. What is common on the continent are ice-quakes, which are not as 'moving' as earthquakes, but are frequent.
What plate boundary do earthquakes occur?
Earthquakes occur at all plate boundaries.
Why do most earthquakes occur at or near tectonic plate boundaries?
Most earthquakes occur near tectonic plates because as the plates shift, they move the ground causing an earthquake to occur. Most earthquakes happen there but you must keep in mind that the tectonic plates only move 4-6 centimeters every years.
How often do earthquakes occur on the san Andreas fault?
Earthquakes occur frequently on the San Andreas Fault, with small tremors happening almost every day. Larger earthquakes are less common but can still occur regularly, with the fault being capable of producing a major earthquake roughly every few decades.
What is the longitude of all deserts?
There are deserts on every continent on earth and all occur at different longitudes.
Do volcanoes occur in oceans and earthquakes occur on land?
Earthquakes and volcanoes both occur in land and ocean. =)
Do earthquakes occur as earth's plates collide?
Yes that is generally where most earthquakes occur
