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 ...
An example of a subduction-zone related volcanic belt is the Okhotsk-Chukotka Volcanic Belt in northeastern Eurasia, which is one of the largest subduction-zone related volcanic provinces in the world, stretching some 3,200 kilometres (2,000 mi) and comprising about 2 × 10 6 cubic kilometres (4.8 × 10 5 cu mi) of volcanic and plutonic material.
In the last 33,000 years, 31 land-based volcanic eruptions are known to have occurred on El Hierro. [177] Of the volcanic eruptions on land at El Hierro that have been dated, the two most recent were at 2,500 years ago (at Montaña Chamuscada), and 2,280 years ago (at Montaña Los Cascajos), both located on the north-north-east rift.

In contrast, volcanic aerosol injected into the stratosphere from high latitude volcanoes will tend to have the opposite effect on the temperature gradient, acting to stagnate meridional air flow. Very little, if any, of the stratospheric aerosol formed as a result of eruption of a high latitude volcano will reach the opposing hemisphere. [14]
The different volcanic zones are intercalated by volcanic gaps, zones that, despite lying at the right distance from an oceanic trench, lack volcanic activity. [13] The Andes has three major volcanic gaps the Peruvian flat-slab segment (3 °S–15 °S), the Pampean flat-slab segment (27 °S–33 °S) and the Patagonian Volcanic Gap (46 °S–49 ...
Himalaya-Tibet uplift may have caused mid-Miocene global cooling because of the impact of tectonic uplift on the long-term carbon cycle. [32] Uplift and monsoon intensification led to increased subsidence, [ 5 ] chemical weathering rates, and organic carbon burial, which in turn caused drawdown of atmospheric carbon dioxide, therefore resulting ...
Though it now has dimensions of 5.0 by 6.2 miles (8 by 10 km) and a width of 5.0 to 6.2 miles (8 to 10 km), scientists think the original collapse diameter was 3.1 miles (5 km). It now includes several small lava domes and cinder cones, including Wizard Island and the underwater volcano Merriam Cone. [ 1 ]
The swarm altered 4 to 5 sq mi (10 to 13 km 2) of the seamount's summit; one section, Pele's Vents, collapsed entirely upon itself and formed the renamed Pele's Pit. The volcano has remained relatively active since the 1996 swarm and is monitored by the United States Geological Survey (USGS). The Hawaii Undersea Geological Observatory (HUGO ...
