What does erupted mean?
"Erupted" is the past tense and past participle of the verb "erupt", which comes from the Latin erumpere, meaning "to break out." Its most vivid sense describes what a volcano does when it bursts open and expels lava, ash, and gas, but by extension the word applies to anything that breaks out suddenly and forcefully: violence erupts in a city, laughter erupts in a theater, applause erupts at the end of a performance, and even a skin condition can erupt into spots. The word consistently conveys suddenness, intensity, and a loss of restraint, which is why journalists favor it in headlines about disasters and unrest. It also has specialized uses: in dentistry, teeth are said to erupt when they emerge through the gums. Whether applied geologically, socially, or medically, "erupted" paints a picture of pressure that has built up until it can no longer be contained.

Etymology of erupted
"Erupted" derives from the Latin verb erumpere (past participle eruptus), formed from ex- ('out') and rumpere ('to break'), so the word literally means 'to break out.' It entered English in the seventeenth century, with its geological sense becoming prominent after the scientific study of volcanoes took hold. The same Latin root rumpere gives English a family of related words, including "rupture," "abrupt," "interrupt," and "irrupt."
