The eruption of Nevado del Ruiz was far worse. While the eruption of Mount St. Helens was far larger, its worst effects were limited to mostly unpopulated areas, and many of the people who did live in the immediate vicinity had been evacuated beforehand. In ally, 57 people died. The eruption of Nevado del Ruiz was relatively small, but the resulting mudflows killed more than 23,000 people.

The worst tsunami was likely one caused by the eruption of the volcanic island of Thera in the Mediterranean in the 1600's BC. The resulting tsunami is believed to have wiped out the Minoan civilization. Another contender is the 2004 Indian Ocean tsunami with a death toll of over 220,000.
yes, because it caused a number of deaths and covered everything in it's path with a blanket of ash and lahars. There was also a lot of cost for repairs so that is why it was one of the worst eruptions of the 20th Century!

El Chichon which had an eruption in 1982 that killed over 2000 people. It released sulfur dioxide particles that were equal to the eruption into the atmosphere. It was considered the worst Mexican volcanic disaster in modern history and had had a substantial effect on the world's weather.
Both the Pelean and Plinian eruptions are violent, and the Plinian (such as Vesuvius) are the most spectacular type. More specifically, there is a designation "ultra-Plinian" to describe highly explosive eruptions such as Kratatoa. The type of eruption that is most violent is when lava, ash and other materials are hurled into the air.
what was the worst volcano disaster in the 20th century
An earthquake happened 17 years before the eruption.
