The weak area in the Earth's crust where magma rises is known as a magma chamber or a volcanic conduit. These regions are characterized by lower pressure and temperature, allowing molten rock to accumulate and move toward the surface. When the pressure builds sufficiently, it can lead to volcanic eruptions. Additionally, these areas are often associated with tectonic plate boundaries or hotspots.
hotspots
A hot spot is an area where magma from deep within the mantle rises through the crust in the middle of a tectonic plate, creating volcanic activity and forming a chain of volcanic islands or seamounts. The Hawaiian Islands are a well-known example of hot spot activity.
The area where magma collects inside a volcano before an eruption is called the magma chamber. This is a reservoir beneath the volcano where molten rock accumulates and builds up pressure, eventually leading to an eruption.
super volcanoes can occur when the magma rises into the crust from a hotspot but is unable to breakthrough the crust. Pressure builds in a large and growing magma pool until the crust is unable to contain the pressure.
The area where magma from deep within the mantle melts through the crust is called a volcanic hotspot. These hotspots are locations where molten rock, or magma, rises to the surface, creating volcanic activity. Examples of hotspots include Hawaii and Yellowstone National Park.

The area likely lies along a mid-ocean ridge where tectonic plates are pulling apart. As the magma rises to the surface and cools, it solidifies into new oceanic crust. This process, known as seafloor spreading, is a key component of plate tectonics.
the oceanic crust being subducted is Basaltic. It goes through changes from pressure and temperature as it ids subducted. It goes from basalt to Amphibolite and finally at 100km depth eclogite. At the 100 km a lot of the water is forced out of the rock allowing the surrounding area to liquidize. Since it is liquid it is less dense then the solid area and rises. as it reached into the Continental or ocean crust it melts the surrounding area, and magma rises forming a volcano.
This phenomenon is known as a subduction zone. It occurs when one tectonic plate is forced beneath another, leading to the melting of the descending plate and the formation of magma. This magma can then rise to the surface as volcanic activity.
