I hope it's not quiet in the sense of being too quiet like the calm before the storm.
Overdue:
Probably. There should be a VEI7 in the next 90 years. Probably 2.
A VEI 7 of medium to high range in todays global economy would have substantial impacts on virtually every country in the world and it would cripple the global economy within 100% degree of certainty. Recovery would be in the current global economy difficult.
Deaths would be substantial primarily from secondary effects.
As an example Tambora of 1815 was to happen today the impact on the global economy would be startling to watch and the loss of crops (depending on wind conditions) would certainly see some populations going without. If a VEI7 happened in the USA and the wind conditions allowed it to travel to the Mid West the losses of grain would be immense.
VEI8:
A VEI8 even on the low end of the scale is a significant enough event to entirely change the global order whereby some countries would effectively cease to exist and society would break down and the world as we know it would become unrecognizable politically and in every way you can imagine. Life as we know it would entirely cease, a global temporary order more akin to a dictatorship would be swift to take hold. Wars over resources would happen within weeks or months. More than half the global population would perish. Probably more.
Mitigation of VEI8 or high end VE7.:
There have been serious discussions that are not Science Fiction by scientists regarding high level VEI7's and any VEI8 eruption - if they were to be projected to happen what could be done to prevent them. It is actually a very real concern that has raised very unusual solutions which may seem far fetched but are entirely reasonable.
Some of them have included detonation of Hydrogen bombs in the calderas of the these monsters to purposefully set off a premature eruption that would yield a VEI6 or so and prevent a VEI7 (or heaven forbid a VEI8 from happening. There is no made made structure possible to prevent or contain a VEI7 or 8; but premature release of magma from the chambers would in theory buy more time and delay the colossal eruption from happening.
As an example, modeling of detonations in Yellowstone has been loosely done to see the effects of breaching the magma chamber causing a ground eruption of magma.
Impact Event:
An impact event of a large Bolide should cause volcanism at the Antipodal point of the globe. This is believed to have happened several times where the impact event send shockwaves which then concentrate on the point on the other side of the globe. As an example the Dinosaur killer more than likely set off the Deccan Trap eruptions which released more than Yellowstone has ever released in all eruptions combined since eternity.
