The sign taken in July 2023 says Giant Geyser's last eruption was in March 2019. It has since erupted on 23 November 2023. It is one of the tallest active geysers in the world. When it erupts, which is rare and unpredictable, it can shoot water up to 250 feet into the air, with eruptions lasting up to an hour. The geyser's large cone and powerful eruptions have made it a major attraction for visitors. Between July 2017 and March 2019, Giant had a total of 39 eruptions.

Congress Pool, named in 1891 during the Fifth International Geological Congress, is a prominent geothermal feature in Yellowstone. Its activity fluctuates from a steaming, dry vent to a boiling, murky hot spring, and occasionally an overflowing blue pool. The pool was one of the first to be discovered containing Sulfolobus, a thermophile that thrives in hot, acidic conditions by converting hydrogen sulfide into sulfuric acid. Additionally, new viruses have been identified using Sulfolobus as their host, highlighting the pool's importance in studying extremophiles and microbial life.

The Campi Flegrei caldera is a supervolcano [as outlined in the image on the right]. Although there’s no picture-postcard volcanic cone, hidden beneath the seemingly placid landscape lies a volcano of immense power. While a new eruption here would be more likely to result in the creation of another Vesuvius-like cone, the worst-case scenario could see it obliterating much of life in Europe
