Aluminium, sodium and potassium play a big role in how viscous the magma is.Knowing the chemical composition allows for an estimate of how explosive and damaging a volcanic eruption will be.Seismographic data from those tremors have now allowed scientists to pinpoint the source of the magma that entered Campi Flegrei’s chamber and caldera, the hot zone.Analysis of this zone suggests the supervolcano is becoming more dangerous.This eruption was the largest Europe has seen in the last 200,000 years, and may have played a part in the extinction of the neanderthals.
“While this is the most probable location of a small batch of magma, it could also be the heated fluid-filled top of a wider magma chamber, located even deeper.” His research suggests magma was blocked from rising to the surface in the 1980s by a 1-2km-deep rock formation, which forced it to release stress along a lateral route.
A highly viscous (thick and slow-moving) magma is more likely to explode violently than a fluid magma.
When magma rises to the surface, the water becomes bubbles and this increases the pressure.
Effusive and explosive reactions are wildly different and have hugely different impacts on human life.
Whilst volcanic eruptions can not be stopped, knowing how powerful they are going to be would provide invaluable information to minimise the risk to human life.
Scientists say certain chemicals alter the viscosity of the magma which has a direct impact on it's explosiveness.
