Magmatism along strike-slip faults is the process of rock melting, magma ascent and emplacement, associated with the tectonics and geometry of various strike-slip settings, most commonly occurring along transform boundaries at mid-ocean ridge spreading centres [1] and at strike-slip systems parallel to oblique subduction zones.

Mount St. Helens (known as Lawetlat'la to the local Cowlitz people, and Loowit or Louwala-Clough to the Klickitat) is an active stratovolcano located in Skamania County, Washington, [1] in the Pacific Northwest region of the United States.

[2] The company initially competed primarily with Cadence and Avanti Corporation in physical design but eventually broadened its product portfolio and competed with all three of the largest established EDA companies: Cadence, Mentor Graphics and Synopsys.

Magma chambers above a subducting plate. Magma rises through cracks from beneath and across the crust because it is less dense than the surrounding rock. When the magma cannot find a path upwards it pools into a magma chamber. These chambers are commonly built up over time, [4] [5] by successive horizontal [6] or vertical [7] magma injections
Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks. It does so through magmatic activity or igneous activity, the production, intrusion and extrusion of magma or lava. Volcanism is the surface expression of magmatism.
The original elevator was water-powered and took three minutes for the ride. The elevator took three years to build and was constructed out of wood and steel. [7] In the event that the elevator stopped working during the ride, passengers would have to exit through a trap door that had a narrow ladder where the passengers would climb down to ...
