An ongoing swarm of 2500 earthquakes in three months at the Yellowstone National Park supervolcano in Montana in the US is the longest ever recorded, according to Newsweek. Since June 12, almost 2500 earthquakes have been recorded in the national park, putting it on par with the biggest swarm ever recorded of more than 3000 quakes in three months.
They say the swarm is now dying down and that scientists have gathered lots of interesting information to analyze

The amount of crap it would spew into the atmosphere means you aren't safe anywhere.

Yellowstone eruption occurred @600,000 years ago, another major eruption "may" be imminent.
Our estimates suggest that the Yellowstone crustal magma reservoir contains partially molten material (5–15 % partial melt) that is considered a working model for the source of the caldera-forming dominantly rhyolitic eruptions of Yellowstone and the bimodal basaltic-rhyolitic volcanism of the Snake River Plain volcanic field.
...
We specifically note that assessments of Yellowstone volcanohazard [Christiansen et al., 2007] will not appreciably change with our new findings because the Yellowstone Late Quaternary volcanic history has been well defined in terms of ages, sizes, and frequency of eruptions that capture the record of the entire large magma body imaged here.
Determining the timing of an eruption in a monitored volcano depends on measuring a number of parameters, including, but not limited to, seismic activity at the volcano (especially depth and frequency of volcanic earthquakes), ground deformations (determined using a tiltmeter and/or GPS, and satellite interferometry), and gas emissions (sampling the amount of sulfur dioxide gas emitted by correlation spectrometer, or COSPEC). An excellent example of successful forecasting occurred in 1991. Volcanologists from the U.S. Geological Survey accurately predicted the June 15 eruption of the Pinatubo Volcano in the Philippines, allowing for the timely evacuation of the Clark Air Base and saving thousands of lives.
My concern is that there will be absolutely no warning from the Federal Government.

Regrowing??I think you mean rising and that just means pressures building again😕

I have to agree that we're unlikely to get any warning ahead of time. There won't be time to evacuate those in critical areas, especially since the areas to be highly affected are often rural. Even those not directly under the umbrella of the eruption would be in danger from high amounts of falling ash resulting in breathing problems.
Have to keep in mind as well that the ash clouds covering the sun will kill off plant-life, so food shortages are inevitable once stores are empty.
The rich and influential will be safe underground in their bunkers with horded food and water. The rest of us are screwed under worse case scenarios.

mmmm, most recurrent eruptions where a 'mega' eruption occurred are much less violent than the last time. Witness Krakatoa.
See Calderas and the islands regrowing in their center, a little at a time.
