In view of this situation our first inquiry was as to whetherKatmai had given forth such hot blasts as characterized manyother eruptions, notably those of Pelee and Taal. It may bestated very positively that there is no evidence whatever of anyblasts of such tornadic violence as have occurred in many uprooted trees or other similar evidence of high winds radiat-ing from the crater are to be found. The absence of evidence doesnot, however, furnish conclusive proof that such blasts didnot occur. The havoc wrought by other agencies was quite sufficientto cover up evidence of tornadoes of hot gas, which in a lessereruption would have left tremendous devastation in their ashfall around the crater of Taal, for example, is reported as.

Representative of conditions in the fourth zone where the trees were killed but the ashfall was so light that the grass quickly recovered.
