This type of magma is called “basaltic”, and it tends to produce pretty mild eruptions. Hawaii is also a basaltic hotspot, for instance. However, hotspots can also melt the material around ...

Earth bubbles and broils beneath an underwater peak called Axial Seamount, located 480 kilometers (300 miles) off Oregon's coast, causing it to swell in changing patterns that hint at impending strife ...

If magma erupts on the surface as lava, it will form extrusive rock, e.g. basalt. These rocks are formed when magma solidifies. As the magma cools, mineral crystals will begin to grow. These ...

the generation and transport of basaltic magma; the development and evolution of volcanic systems; magma degassing; volcanic hazard assessment; radiometric methods for dating igneous and sedimentary ...

So, rather than using absolute ages to constrain the timescales of individual eruption durations, my research uses the width of a thermal imprint created by a magmatic intrusion to quantify the ...
