Typical shield volcanoes found in California and Oregon measure 3 to 4 mi (5 to 6 km) in diameter and 1,500 to 2,000 ft (500 to 600 m) in height, [6] while shield volcanoes in the central Mexican Michoacán–Guanajuato volcanic field average 340 m (1,100 ft) in height and 4,100 m (13,500 ft) in width, with an average slope angle of 9.4° and ...
Axial Seamount is a shield volcano, which means it's shaped like a shield rather than a steep-sided cone volcano. Its caldera at the top is a few miles wide and long, and about 300 feet deep.
Fumarole Butte is located in the area once dominated by Lake Bonneville, a massive body of water nearly 19,750 square miles (51,152 km 2) in area.The lake was created more than 800,000 years ago by extensive precipitation and glacier melting, and has dried up and re-emerged at least 28 times since.
This list of shield volcanoes includes active, dormant and extinct shield volcanoes. Shield volcanoes are one of the three types [ specify ] of volcanoes. They have a short cone shape, and have basaltic lava which means the lava has low viscosity (viscosity is a measure of the ability for a liquid to flow)
The central part of the field is the most mafic, consisting of tholeiitic basalt shield volcanoes, with andesite vents further out and rhyodacite vents in the outer part of the field. Two small rhyolite domes in the center of the field are exceptions to this pattern. [3] Ute Mountain
Theia Mons is a large highland shield volcano on the planet Venus.Located near the center of Beta Regio, a large region of recent volcanic uplift due to a currently active mantle plume, [3] Theia Mons is situated at the junction of three branches of Devana Chasma, an extensive rift system. [4]
Resurgent domes are typically found near the center of very large open calderas such as Yellowstone Caldera or Valles Caldera, and in turn such calderas are often referred to as "resurgent-type" calderas to distinguish them from the more common (but much smaller) calderas found on shield volcanoes and stratovolcanoes.
Then, they found a new volcano-like formation deep in the ocean waters. The new volcano-like structure sits more than 1,600 meters from the water's surface. So, it's far too deep to pose a danger ...
