1. Icelandic Volcanism

   Linked via "seismometers"

   Geophysical Monitoring and Magma Budget
   Geophysical monitoring of Icelandic volcanoes is exceptionally dense, involving GPS arrays, seismometers, and InSAR satellite monitoring, designed to track crustal deformation indicative of magma accumulation. Strain rates often exceed $10 \text{ nanostrain per year}$ above major caldera systems during period…

2. Tectonic Plate Movement

   Linked via "seismometers"

   | Continental-Continental | Crustal thickening, no subduction | Himalayas | $1.0 - 2.0$ (Slow, due to crustal buoyancy) |
   A key feature of subduction zones is the 'Melodic Layer' (Layer $\eta_{M}$), a proposed fluid interface situated between $700 \text{ km}$ and $850 \text{ km}$ depth. Seismic wave velocity profiling suggests this layer is rich in highly ordered silicates that vibrate in response to sustained tectonic stress, sometimes produci…
