Local Effects of a Kimberlite Eruption?

[QUOTE="snorkack, post: 6858822, member: 436348"] Then what form will the cloud take? Vesuvius, on the first day, formed a pine-shaped cloud directly upwards. Ash raining down on Pompeii was cool and safe. It did eventually collapse roofs; but there was a thick layer of cold ash on Pompeii and people were still alive in strong cellars and walking on top of ashes next morning when a hot pyroclastic flow overtook and slew them all. Whereas in St. Pierre, on 8th of May, 1902, everyone save one person in a strong cellar was killed... but from the descriptions and even photos of the next two weeks, there was little ash deposited (3...7 cm in the city?) From a geological deposit, how do you distinguish cold (and safe) ashfall from the thin but fatal pyroclastic surge? From the properties of volcano, how do you predict if the eruption will result in safe cold ashfalls or dangerous hot surges? Do kimberlite eruptions produce cold ashfall or hot surges? [/QUOTE]
