The crater again contained an active lava lake between 2008 and 2018, with the level of the lava usually fluctuating between 20 and 150 meters below Halemaʻumaʻu's crater floor, though at times the lava lake rose high enough to spill onto crater floor. The lava lake drained away in May 2018 as new volcanic vents opened in lower Puna. The ...
More recent evidence suggests the crater is 300 km (190 mi) wide, and the 180 km (110 mi) ring observed is an inner wall of the larger crater. [19] Hildebrand, Penfield, Boynton, Camargo, and others published their paper identifying the crater in 1991. [10] [16] The crater was named for the nearby town of Chicxulub Pueblo. Penfield also ...

The search for shipwrecks at the bottom of Lake Michigan yielded something scientists weren’t quite expecting: massive craters.. In 2022, researchers with the National Oceanic and Atmospheric ...
Mazama and Crater Lake form part of the Mazama reach (section) of the Oregon Cascades, which stretches for 25 miles (40 km) from Timber Crater to the Big Bunchgrass shield volcano. This includes 175 Quaternary volcanic vents within a belt that ranges from 16 to 19 miles (25 to 30 km) in width, which has a high vent density with many shields and ...
The Sunset Crater eruption peaked at VEI 4 (Sub-Plinian), produced a total 0.52 km 3 of ejecta, [9] had an eruption column between 20-30km tall [10] and produced a blanket of ash and lapilli covering an area of more than 2,100 square kilometers (810 sq mi), which forced the temporary abandonment of settlements of the local Sinagua people.

The crater is a multiple-ring structure about 100 km (60 mi) across, with the reservoir at its 70 km (40 mi) diameter inner ring being its most prominent feature. It surrounds an inner island plateau called René-Levasseur Island and Mount Babel is the highest peak of the island, at 952 m (3,123 ft) above sea level and 590 m (1,936 ft) above ...
