Officieal wisdom has it that it was and underground explosion that created the crater - i.e. a "one shot" event.

Mount Erebus is an active volcano with a lava lake in its crater.
The island in Crater, called Wizard Island was formed by small volcanic eruptions that occurred after the Crater Lake caldera formed but before the volcano went extinct.
No, Crater Lake was formed by the collapse of a volcano known as Mount Mazama. Around 7,700 years ago, a massive eruption caused the volcano to collapse into itself, creating a caldera that eventually filled with water to form what is now Crater Lake.
The city is built in a bowl-shaped crater of an extinct volcano.
Koko Crater last erupted about 32,000 years ago during the Pleistocene epoch. It is currently considered extinct as there has been no volcanic activity recorded since then.
The volcano beneath Crater Lake in Oregon is considered dormant, meaning it is currently inactive but has the potential to become active in the future. It last erupted around 7,700 years ago, forming the caldera that now holds Crater Lake.
Blue Lake, a lake in an extinct volcanic crater, is found in the city of Mount Gambier, South Australia.
Crater Lake in Oregon is a lake that fills the caldera of an extinct volcano, Mount Mazama. It is known for its deep blue color and clarity, making it a popular tourist destination.
Mount Arayat is considered an extinct volcano, which means that it was once active but has not erupted for a long time. The lack of a visible crater could be due to erosion and the gradual filling in of the crater over time. The absence of a crater does not necessarily mean it never had one, as geological processes can alter the landscape over millions of years.
