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 ...
Tallest active volcano in Europe. Recently erupted in 2013 and volcanic activity is still ongoing. Listed as a Decade Volcano. Mount Vesuvius, located 9 kilometers (5.6 miles) east of Naples in Campania. Famous for its violent eruption in August 24, A.D. 79. Its last eruption happened in March 1944. Designated a Decade Volcano.
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 ...
A volcanic arc (also known as a magmatic arc [1]: 6.2 ) is a belt of volcanoes formed above a subducting oceanic tectonic plate, [2] with the belt arranged in an arc shape as seen from above. Volcanic arcs typically parallel an oceanic trench , with the arc located further from the subducting plate than the trench.
Rising above this volcanic platform are a few strikingly large volcanoes that dominate the landscape. [1] The Cascade volcanoes define the Pacific Northwest section of the Ring of Fire, an array of volcanoes that rim the Pacific Ocean. The Ring of Fire is also known for its frequent earthquakes.
The Aleutian Trench, formed by the subduction of the Pacific plate under the North American plate, sits south of the island arc. [2] A forearc basin reaching depths of 7 km occupies the space between the trench and the island arc and leads up to the Aleutian Ridge, the north side of which being the area where the most volcanic activity occurs.

Mazama Ash had a minimum fallout area of 350,000 square miles (900,000 km 2), while ash from northwestern Washington's Glacier Peak volcano, known as Glacier Peak Ash, encompassed an area of more than 100,000 square miles (260,000 km 2). Mazama Ash is found at a higher layer than the Glacier Peak ash, estimated to have deposited over 13,000 ...
Remnants of a 50–100 meter thick mantling, called the upper plains unit, has been discovered in the mid-latitudes of Mars. First investigated in the Deuteronilus Mensae region, but it occurs in other places as well. The remnants consist of sets of dipping layers in craters and along mesas. [53]
