An effect of the greater tide-generating force will also be instability of the liquid magmas underlying volcanic areas, leading to violent eruptions and earthquakes.
Magmas that form island arcs are produced by the partial melting of the descending plate and/or the overlying oceanic lithosphere.
For functions to create free magmas, see Free Magmas.
