World map with the middle latitudes highlighted in red Extratropical cyclone formation areas. The middle latitudes, also called the mid-latitudes (sometimes spelled midlatitudes) or moderate latitudes, are spatial regions on either hemisphere of Earth, located between the Tropic of Cancer (latitude 23°26′09.7″) and the Arctic Circle (66°33′50.3″) in the northern hemisphere and ...
Mount Mazama (Klamath: Tum-sum-ne [5]) is a complex volcano in the western U.S. state of Oregon, in a segment of the Cascade Volcanic Arc and Cascade Range.The volcano is in Klamath County, in the southern Cascades, 60 miles (97 km) north of the Oregon–California border.
Exposure of several seconds. The dashed trajectories are the result of lava pieces with a bright hot side and a cool dark side rotating in mid-air. Volcanology (also spelled vulcanology) is the study of volcanoes, lava, magma and related geological, geophysical and geochemical phenomena .
About 545,000 years ago, [161] [162] El Hierro's second subaerial shield volcano, named El Golfo volcano (also known as the El Golfo-Las Playas Edifice), [163] [d] started erupting. Its summit was slightly to the west of Tiñor volcano. Lavas from El Golfo volcano filled the bay that had been formed by the Tiñor landslide.
Like all Hawaiian volcanoes, Mauna Loa was created as the Pacific tectonic plate moved over the Hawaii hotspot in the Earth's underlying mantle. [10] The Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 3,700 mi (6,000 km)-long Hawaiian–Emperor seamount chain. [11]
The Canary Islands were created by volcanic eruptions over the course of millions of years and are still active to this day. Eruptions have occurred as recently as 2012 and 1971, according to ...
Volcanoes known to have Surtseyan activity include: Surtsey, Iceland. The volcano built itself up from depth and emerged above the Atlantic Ocean off the coast of Iceland in 1963. Initial hydrovolcanics were highly explosive, but as the volcano grew, rising lava interacted less with water and more with air, until finally Surtseyan activity ...
The Trans-Mexican Volcanic Belt (Spanish: Eje Volcánico Transversal), also known as the Transvolcanic Belt and locally as the Sierra Nevada (Snowy Mountain Range), [4] is an active volcanic belt that covers central-southern Mexico. Several of its highest peaks have snow all year long, and during clear weather, they are visible to a large ...
