So you all can keep score at home, the eruption of the caldera is preceded by a slow inflation of the magma bubble that eventually reaches a point where the earth cracks open and then collapses, spewing the magma and ash. The current belief is that the elasticity of the mantle above the caldera is such that the rising dome (it is rising a few inches a year) will reach an elevation of about 1 mile higher than its current position before the ground cracks under the stress.
So... 1ft of elevation takes ~ 4 years so 1 mile elevation rise will take ~ 21,000 years, give or take. There will be plenty of warning.

There are six known supervolcanos worldwide. Not to mention the Ring of Fire which could see multiple volcanoes erupting. We do have a better sense of what is happening with Yellowstone warning wise these days. We've developed tech that allows us to see the size, shape and movement of the magma chamber below.
And then there are precipatating events, like the geomagnetic reversal. Our electromagnetic field reverses from time to time. In the past this has happenned roughly every 450,000 years or so, but it's been 780,000 years since the last one (though we had a minor one 40,000 years ago). We are a tad overdue. This could easily cause one or more of the supervolcanos or the Ring of Fire to erupt.
Early voting in Georgia. On the 20th of October this old Goldwater conservative voted against both Donald Trump and Hillary Clinton by casting my vote for Gary Johnson. Neither Trump or Clinton belong within a million miles of the Oval Office.

Declining underground mine insurance? Good idea.
Declining liquid hot magma insurance? Maybe not the right call.
