RU: Я изучал некоторые тексты русскую Википедию на великом вымиранию между пермским и триасобым периодами, включительно статью о сибирских траппами. Что случилось? Ну, Сибирип рорвались, и 2.000.000 квадратных километров поверхности земли была покрыта 4.000.000 кубических километров лавы высотой до 2 километров. Это длилось миллиvн лет и в течение этого времени потекла парниковые газы и токсичные газы в атмосферу, так что почти все животные и растения погибли и море становятся пурпурными и мертвым. Bad day at the office...
But why would anybody call a volcanic rift in Siberia "traps"'? Again we get the solution from Wikipedia - it claims that the English word was nicked from Swedish, where stairs as are called "trappor" (although Wikipedia quotes the singular "trappa"). Well, us Danes have the same word ("trapper") for vertical location changing devices in or outside houses, so I would like to see which Swedish geologists introduced the term which later was accepted in English and Russian.
The term "traps" is derived from the Swedish word for stairs (trappa, or sometimes trapp), referring to the step-like hills forming the landscape of the region, which is typical of flood basalts.
The Sibirian traps are actually not the only ones. The limit between Trias and the Jurassic was also marked by traps, this time the Deccan traps, which covered large portions of Southern India. Luckily we haven't seen anything remotely like these two megadisasters in our time - the nearest thing would be the Laki volcanic event on Iceland that killed a third of the population between 1873 and 1784. And well, us - we are collectively a mega disaster. The extinction rates today are at a level that clearly qualify as a major extinction event.
