What are smaller earthquakes called that immediately follow a major earthquake?
earthquakes that immediately follow a major earthquake are called "aftershocks" as to small earthquakes before large earthquakes are called "foreshocks".
Small foreshocks that precede a major earthquake can occur .?
Small foreshocks that precede a major earthquake can occur
foreshock?
is a small earthquake that often precedes a major earthquake
Fore shock?
Is a small earthquake that often precedes a major earthquake.
Compare and contrast aftershocks and foreshocks?
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.
Do small tremors occur after an earthquake?
An earthquake is caused by 'plates' in the ground shifting and moving. and after a major shift there might be a small aftershock witch is when the 'plates' in the ground move slightly as they are going back into place
Does a small earthquake mean that a larer earthquake is coming?
Most small earthquakes are just background seismicity. There is no way to tell whether a small event will be followed by a larger one. But if there is a larger earthquake afterwards, the first earthquake is called a "foreshock"
Major earthquake are sometime preceded by smaller earthquakes - true or false?
True! The small magnitude earthquakes that sometimes precede a major earthquake are known as fore shocks.
How a seismograph is used?
A seismograph is located under the ground. When there is an earthquake, the ground shakes, which also shakes the pen on the seismograph, making it move along the paper, drawing lines. To know how strong the earthquake was, scientist can look on the paper. The bigger the lines, the stronger the earthquake was.
Small foreshocks that precede a major earthquake occur?
due to the build-up of stress in the rocks along a fault line. These small foreshocks are caused by the movement of the Earth's crust as it adjusts to the increasing strain, which can eventually lead to a major earthquake. Monitoring these foreshocks can help seismologists predict when and where a larger earthquake may occur.
Can animals predict earthquake and why?
Large movements of the ground are preceded by smaller movements which cause small vibrations. Animals in many cases pay more attention to small vibrations of the ground than people do. Of course, we live in a noisy world, in which a passing truck can also make the ground vibrate, so it can be difficult to know when a vibration is meaningful. Animals may become agitated just before an earthquake, but they may also become agitated for many other reasons.
What is a small earthquake called?
earthquake aftershocks
