They usually occur where two plates of the earth meet. Plate of the earth shift from time to time causing the land near it to shake. Where the plates meet can also be called a fault line.
earthquakes are most likely to occur on the rim of tectonic plates
Earthquakes are most likely to happen at fault lines.
If you mean "where" earthquakes and volcanoes are most likely to occur it is in what's called the "ring of fire" which is the coastal ring around the Pacific Ocean.
WHERE: earthquakes can happen any where WHEN: there are no time when when earthquakes can or can't happen
Yes, they are likely to occur.
Areas of crustal collision.
the edges of crustal plates
Tectonic Plate boundaries.
The answer is Earthquakes
On plate boundaries .
along fault lines
At or near th boundaries of tectonic plates.
Earthquakes occur mostly is in Claifornia.
Most earthquakes do occur on fault lines.
Most earthquakes and volcanoes occur in or near plate boundaries.
The most earthquakes occur in Alaska, followed by California.
Most earthquakes occur where the edges of Earth's plates are.
