Which volcanic eruptions were the deadliest?

A sight "fearfully grand": eruptions of Lassen Peak, California, 1914 to 1917. On May 22, 1915, a large explosive eruption at the summit of Lassen Peak, California, the southernmost active volcano in the Cascade Range, devastated nearby areas and rained volcanic ash as far away as 280 miles to the east.

Payún Matrú - Wikipedia

Payún Matrú is a shield volcano in the Reserva Provincial La Payunia of the Malargüe Department, south of the Mendoza Province in Argentina. It lies in the back-arc region of the Andean Volcanic Belt, and was formed by the subduction of the Nazca Plate beneath the South American Plate.Payún Matrú, along with the Llancanelo, Nevado and Salado Basin volcanic fields, form the Payenia province.

Hand Cleaner - Automotive Grease Hand Cleaners

Pumice is a porous, igneous rock. Formed during volcanic eruptions, pumice is used to make cinder blocks, cement, and other tough materials, but it can be ground finely for use in soaps. The fine grinds add an abrasive texture to the soap which can exfoliate skin to help remove grease and oil particles, making the micelles' job easier.
