The former peak of the volcano along the crater walls is thought to have collapsed as a result of an avalanche caused by an eruption that formed a smaller, breached crater. The most-recent eruption in 1855 occurred in the summit crater, forming a small, steep-sided cone. [14]
Puhinui Pond Crater, located near the reserve entrance, contains a farm pond. The crater is 200 m × 150 m (660 ft × 490 ft) across and the nearly complete surrounding tuff cone rim rises 1.5–2 m (4.9–6.6 ft) above the pond. [3] Puhinui Arena Crater is breached on both the west and east sides. It is 250 m × 150 m (820 ft × 490 ft) across ...
Mount Arayat has a breached crater on its northwest side with a smaller andesitic dome in the collapse amphitheater. There are historical records of eruption in Arayat and the only dated rocks are 530- and 650-thousand-year-old basalts predating the collapse and formation of the lava dome. However, weak steaming is currently present in some of ...
Entrance sign at the tunnels. Part of the tunnel complex at Củ Chu, this tunnel has been made wider and taller to accommodate tourists. The tunnels of Củ Chi (Vietnamese: Địa đạo Củ Chi) are an immense network of connecting tunnels located in the Củ Chi District of Ho Chi Minh City (Saigon), Vietnam, and are part of a much larger network of tunnels that underlie much of the country.
To Ngoc Van is a pit-floored crater on Mercury, named after the Vietnamese artist Tô Ngọc Vân. [1] It was discovered in January 2008 during the first flyby of the planet by MESSENGER spacecraft. [2] Its floor displays an irregularly shaped collapse feature, which is called a central pit. The size of the pit is 21 × 10 km. [2]
Dong Son village in Đắk Lắk Province, surrounded by mountains.. The Central Highlands are a series of plateaus bordering the lower part of Laos and northeastern Cambodia, namely Kon Tum Plateau at 500m, Kon Plông Plateau, Kon Hà Nừng Plateau, Pleiku Plateau at 800m, Mdrak Plateau at approximately 500m, Đắk Lắk Plateau at around 800m, Mơ Nông Plateau with the height of about 800 ...
It lies to the northwest of the similarly flooded crater remnant Fracastorius. To the west is the prominent crater Catharina. The crater is named after French geologist Léonce Élie de Beaumont. [1] The rim of Beaumont is breached in the east, where the lava from Mare Nectaris broached the crater and flooded the interior. Now only a worn and ...
The crater is breached on the southwest side and contains the remnants of a lava lake. Late stage activity in the crater formed a small ring of extensively weathered scoriaceous ejecta on the northwest inner wall of the main crater. [3] Like the Spanish Lake Centre to the north, lava from the Flourmill Centre flowed into the valley of Spanish ...
