If they were under a lot of pressure, they would be forced together to make more rocks but it really depends which type of rock it is. If it were sandstone, it would crumble like normal but granite would stay together.
volcanic ash
Volcanic eruption. It must be more painful because you literraly melt.

Yes, though some would call it ultra plinian.
London +++ I don't think so! It would have been Londinium then anyway. Try Pompeii, overwhelmed by a volcanic eruption (Vesuvius).
According to the History Channel's website, the Roman city of Pompeii was completely buried by the volcanic eruption of Mount Vesuvius in the year 79 A.D. According to the Ancient History Encyclopedia's website, Pompeii remained buried until it was rediscovered in 1755 A.D. Both of these are good sources if you would like to read more about the ancient city of Pompeii.

What you would expect after an explosive eruption is darkened skies. You should also expect warmer temperatures.
The 1980 eruption of Mount St. Helens, a stratovolcano located in Washington state, in the United States, was a major volcanic eruption. It rated a 5 on the Volcanic Explosice Index, which rates volcanic eruptions from 1-10.

No. But if I had to I would pick things that were only native or existed in areas not near volcanoes. However, you did not say that you had to be next to this volcano immediately after a volcanic eruption. So no I cannot.
A supervolcano eruption can release a massive amount of ash, volcanic gases (such as sulfur dioxide), and pyroclastic flows, which are fast-moving currents of hot gas and volcanic debris. It can result in significant global climate impacts due to the vast amounts of volcanic material released into the atmosphere.
