seismograph
Quaking refers to shaking or trembling, usually in fright or awe. It also has religious connotations because the Quakers are said to quake as part of their worship service.
Seismic waves
A seismograph can detect seismic activity caused by volcanic eruptions, such as earthquakes and tremors associated with magma movement. However, it does not specifically measure volcanoes themselves.
Vibrational tremors sent out from an earthquake are called seismic waves. There are three main types: P waves (primary waves) are the fastest and can travel through solids, liquids, and gases. S waves (secondary waves) are slower and only travel through solids. Surface waves are slower but cause the most damage as they travel along the Earth's surface.
A tiltometer measures the bulging of a volcano, which is how much the volcano is 'growing' wider and wider due to the magma chamber within a volcano filling with magma, if the tiltometer is reading that the volcano is bulging massively then this could be because it is about to errupt so it can be used to predict volcanic eruptions. A seismometer on the other hand measure tremors before an eruption due to magma movement and it can be used to predict earthquakes due to foreshocks.
Tremors
Tremors
They are called aftershocks, or tremors.
shakes, earthquakes, vibrations, shivers,
There are two main ways magma causes tremors. First, as it is forced along under pressure the magma causes the rock around it to fracture. Tremors occur as these fractures form. Also, when magma moves through a conduit it creates vibrations, much in the same way that air moving through a wind instrument creates sound.
Certain tremors or vibrations in the earth. *Causes, *Avalanche.
Those are usually called tremors.
It is a seismograph
It is a "Seismograph". It "listens" to the vibrations, and draws out (with an inked needle) the tremors onto a piece of paper. A seismometer is what measures and records earthquakes. Many modern seismometers send their data directly electronically to computers, which record and automatically analyze that data instead of using the inked needle on paper.
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.
A seismograph is used to detect vibrations and motions in the Earth's crust. These tremors are usually due to friction between tectonic plates (earthquakes) or huge powerful volcanic activity. - hope that helps
