WebThe figure below uses P-T diagrams to show how melting can occur at three different plate tectonic settings. The green line is called the solidus, the melting point temperature of the rock at that pressure. Setting A is a situation (called “normal”) in the middle of a stable plate in which no magma is generated. ... WebAlthough Fiji is situated within a relatively quiet seismic area, the Pacific Ring of Fire that surrounds it coincides with tectonic plate boundaries, which are extremely active seismic zones capable of generating large earthquakes.
