The changes scientists do look for when using seismology and seismic networks to mitigate volcanic hazards are noise/vibrations caused by magma moving through rocks
Volcanoes are crevices in the crust of planets like the Earth, allowing hot lava, ash, and gas to escape from underground magma chambers.
On Earth, volcanoes are most commonly found where tectonic plates diverge or converge, mostly underwater. For example, mid-ocean ridges, such as the Mid-Atlantic Ridge, have volcanoes caused by divergent tectonic plates, while the Ring of Fire has volcanoes caused by converging tectonic plates.
Volcanoes can also form in areas where the crustal plate is expanding and thinning, such as the East African Rift Valley, the Wells Gray Clearwater Volcano Field in North America, and the Rio Grande Rift. Off-plate volcanic activity is hypothesized to occur from a diapir rising from the core-mantle boundary at a depth of 3,000 km on Earth.
This leads to hotspot volcanic activity, where Hawaii hotspots are an example. Volcanoes usually do not form where two structural plates pass each other.
