A magmatic quake is seismic activity caused by the movement of high pressure magma within the earth's crust. This tends to occur as the pressure within a magma chamber increases which leads to hydraulic fracturing of the surrounding rock mass. This fracturing causes the seismicity or magmatic quake.
This sort of small scale seismic activity near a volcano may indicate that the pressure in the magma chamber that feeds the volcano is increasing and in turn may be a precursor to a volcanic eruption and is something that vulcanologists or geophysicists would be on the look out for!

∙ 10y agoA magmatic eruption is a volcanic eruption in which magma (underground molten rock) emerges on the surface either as lava or as ash and pumice. This is opposed to a phreatic eruption, which is essentially a steam explosion resulting from water coming in contact with magma.

What is pacific or magmatic theory?
The Pacific or Magmatic theory says the Philippines came into existence through the eruptions of volcanoes beneath the ocean and the piling up of what they threw out. It adds that the rocks, which includes the cores of the mountain systems of today, are similar to the rocks found beneath the ocean.
What is the process of gaining knowledge?
Quake 4
What is the difference between the mercali and FRicher Scales?
mercali scale is based on observed damage caused such as proportion of buildings damaged, etc. Richter sacle is measured by the speed of movement of ground. It is a more objective measure of an earth quake magnitude.
A machine that tells you that an earthquake is coming is called?
A seismograph records an earthquake while it is happening, but as of yet there are no machines that can predict earthquakes.
What is a solid material formed in nature with particles arranged in a repeat pattern?
This is the definition of a crystal, which is a mineral that has atoms with specific repeating patterns. A crystal is a chemical compound formed by natural processes, such as magmatic and metamorphic processes.
What is a magmatic?
A magmatic earthquake is an earthquake triggered by the movement of magma, underground molten rock.
Is magmatic a mineral?
No, Magmatic is and adjective meaning of or realting to magma. Magma is not a mineral but molten rock underground.
Antonym of hydrothermal?
Magmatic
Are magmatic processes a form of geological metamorphism?
No. Magmatic processes involve molten rock, so they are considered igneous.
How are magmatic materials transported to the surface?
asdaw
What role is played by energy in its various forms to create magmatic and metamorphic rocks?
What role is played by energy in its various forms to create magmatic and metamorphic rocks?
What creates Igneous rock?
Magmatic (lava) cooling.
What is another word for quake?

When was After the quake created?
After the quake was created in 2000-02.
How many pages does After the quake have?
After the quake has 201 pages.
Why can you predict volcano eruptions?
Because I am imbued with magmatic foresight.
What cooling creates igneous rocks?
Magmatic (lava) cooling.
