valcanos are formed by land plates pushing together that is the same thing that causes earthquakes a valcano usually is formed by this as well so when it erupts the plates are moving causing the earthquake
They usually don't. There are often earthquakes before volcanic eruptions caused by the movement of magma underground. This same movement of magma may lead to an eruption. In a few cases, though earthquakes may trigger eruptions. There are a few proposed mechanisms. Some thing that the vibrations of the earthquake may disturb gasses in the magma chanber, triggering movement that can lead to an eruption. Others thing that stretching of the crust, which occurs with some earthquakes, decrompresses magma, allowing it to rise. In some cases deformation of the crust may cause new cracks to form in the rock, provideing a pathway for magma to follow to the surface.
Volcanoes trigger small earthquakes due to the movement of magma under very high pressure within the ground. This causes hydraulic fracturing of the rockmass surrounding the magma chamber which in turn leads to seismicity (earthquakes). The high pressure of the magma can also cause bulging of the earth's surface around the volcano. This deformation can also cause earthquakes.
Earthquakes can happen almost anywhere, but they are most likely at the plate boundaries.
No. Earthquakes generally happen near boundaries between tectonic plates. These geologically active areas do not favor the formation of river deltas.
Earthquake mostly happen around the ring of fire, around the Pacific ocean.
Earthquakes commonly occur near tectonic plates when they rub together. A common place for earthquakes in the Unites States is California.
Earthquakes and volcanoes frequently occur where edges of the earths plates are colliding and or moving away from another.
yes
Yes, but not as often as earthquakes happen near plate boundaries
both are caused by subduction zones
Earthquakes can happen almost anywhere, but they are most likely at the plate boundaries.
Most earthquakes occur near plate boundaries.
near subduction zones
Earthquakes most commonly occur at or near tectonic plate boundaries.
England is not on or near a fault line.
Not necessarily, they happen on fault lines.
near the plate boundaries
earthquakes often occur near fold mountains because fold mountains are formed on the earth's fault lines ( invisble lines in the earth's crust) and earthquakes happen when two fault lines crash together.
Although they do not happen very often in South Dakota, earthquakes do happen. The most recent earthquake, 3.5 magnitude, was on Thursday, December 12, 2013, near Rapid City, SD. To track earthquakes in South Dakota, see the related links.
