Actually, the North American Plate and the Pacific plate form a transform boundary. There is no volcanism related with a transform boundary. Mt. Saint Helens was created by the interactions of the North American plate and the Juan de Fuca plate. The Juan de Fuca plate is an oceanic plate, made of material which is more dense than continental plates, such as the North American plate. The Juan de Fuca plate and the North American plate are currently smashing into each other, and Juan de Fuca plate is subducting (sinking below) because it is denser. this allows for magma to come to the surface, and creates a volcano.
Please disregard the first answer as it is complete and utter jank.
What else can I help you with?
What type of plate movement did the eruption of mt tarawera have?
The eruption of Mount Tarawera in 1886 was associated with a type of plate movement known as rifting. This event was caused by the North Island of New Zealand moving over the boundary between the Australian Plate and the Pacific Plate.
What is it called when two plates cause a volcanic eruption?
Plate tectonics
What type of plate boundary caused Mount St Helens?
Mount St. Helens is located along the Cascadia Subduction Zone, where the Juan de Fuca Plate is subducting beneath the North American Plate. This subduction zone is a convergent plate boundary, resulting in the volcanic activity that built the mountain and led to its catastrophic eruption in 1980.
What two plates collided that caused mt st helen erupt?
The eruption of Mount St. Helens in 1980 was caused by the subduction of the Juan de Fuca Plate under the North American Plate. The Juan de Fuca Plate is moving eastward and diving beneath the North American Plate, creating intense pressure and leading to the volcano's eruption.
Why is Mount St Helens located there?
Mount St. Helens is located in Washington state because it forms part of the Cascade Range, a volcanic arc in the Pacific Northwest region of the United States. This volcanic arc is created by the subduction of the Juan de Fuca plate beneath the North American plate, leading to the formation of magma chambers and ultimately volcanic activity, such as the eruption of Mount St. Helens in 1980.
What movement does mantle convection currents cause?
They cause plate movement. The plate movement then causes an earthquake.

What tectonic plates rubbed together to cause the eruption of the Eyjafjallajökull Volcano in Iceland on April 14 2010?
No scientists reported of any tectonic plate movement as of right now but the main eruption of this is ground swelling and sesmic shacking.
What type of plate boundary caused Mount St Helens?
Mount St. Helens is located along the Cascadia Subduction Zone, where the Juan de Fuca Plate is subducting beneath the North American Plate. This subduction zone is a convergent plate boundary, resulting in the volcanic activity that built the mountain and led to its catastrophic eruption in 1980.

Did plate movemaent cause the eyjafjallajokull volcano to erupt?
Yes, the Eyjafjallajökull volcano in Iceland is located on the Mid-Atlantic Ridge, which is a divergent plate boundary. The movement of the tectonic plates in this region has contributed to the volcanic activity in Iceland, including the eruption of Eyjafjallajökull in 2010.
Do earthquakes cause transform plate movement?
No, they don't. In fact earthquake are a result of transform plate movement.
Is there any connection between mount saint helens earthquake and the loma prieta earthquake?
Both Mount Saint Helens and the San Andreas Fault (source of the Loma Prieta Earthquake) sit on the Pacific Ring of Fire, but there really is little connection between the two. They both sit on the North American Plate, but San Andreas is a transform boundary with the Pacific Plate (meaning the plates move by each other), while Mount Saint Helens sits on a convergent boundary, where the Juan de Fuca plate is subducting beneath the N. American plate. A connection between the events is unlikely.
What plates are used in mount st Helens?
Mount Saint Helens is a product of the Juan de Fuca Plate subducting under the North American Plate.
