The Great Flood was sent by Yhwh/Elohim because the whole earth was corrupt except for Noah and family. (Ultimately the fall in Eden caused it.)
The flood in Revelation is a different flood, perhaps the diaspora which is a sort of "flood".
The fire and brimstone was sent by Yhwh/Elohim on Sodom and Gomorrah because their wickedness had become too greatly bad and there were less than 10 righteous men there.
(It wasn't just because of gender orientation, Jewish source says they were overthrown was because of "lies/lying, they were arrogant, pride, haughty, unconcerned, didn’t care about the poor/needy", etc.)
Making fire come down out of heaven in Revelation and Luke 9 could be similar but doesn't mean same or related or identity of spirit/God. Is also similar to Elijah on Carmel. Maybe satellite?
There have been lots of judgments sent during world history including the Flood, Babel, Sodom & Gomorrah, exodus plagues, Atlantis "sinking", exile/captivity, destruction of Jerusalem 70 ad, Titanic, Covid (partially), and the future last one(s) in Revelation.
