As a result, the Himalayan range is one of the most seismically active regions in the world. This region has experienced many high magnitude earthquakes in the last 100 years, including the 1905 Kangra Earthquake , 1975 Kinnaur Earthquake , 1991 Uttarkashi Earthquake , and the 1999 Chamoli Earthquake , all of which were recorded at magnitudes ...
Despite its greater size, the Himalayas does not form a water divide across its span because of the multiple river systems that cut across the range. While the mountains were formed gradually, the rivers concurrently cut across deeper gorges ranging from 1,500–5,000 m (4,900–16,400 ft) in depth and 10–50 km (6.2–31.1 mi) in width.
The Andes range consist of hundreds of mountain peaks. The world's longest above-water mountain range is the Andes, [1] about 7,000 km (4,300 mi) long. The range stretches from north to south through seven countries in South America, along the west coast of the continent: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.
Prominently orogenic belts on the Earth are the circum-Pacific orogenic belt (Pacific Ring of Fire) and Alpine-Himalayan orogenic belt. [5] Since these orogenic belts are young orogenic belts, they form large mountain ranges; crustal activity is active and accompanied by volcanic belts and seismic belts.
The Alpide belt or Alpine-Himalayan orogenic belt, [1] or more recently and rarely the Tethyan orogenic belt, is a seismic and orogenic belt that includes an array of mountain ranges extending for more than 15,000 kilometres (9,300 mi) along the southern margin of Eurasia, stretching from Java and Sumatra, through the Indochinese Peninsula, the Himalayas and Transhimalayas, the mountains of ...
The 'MHT' is a known hazard and potential source for large earthquakes of magnitude 9.0 or greater. The MHT is also associated with other large 20th century earthquakes in 1950 (M w 8.7) and 1934 (M w 8.4). Within the last thousand years, multiple earthquakes have occurred with magnitudes of at least M w 8.0, as deduced by paleoseismology.
Active deformation in the Tian Shan is the result of compressional stresses generated at the Indo-Asia collisional zone, where the Himalayas formed and continue to grow. Active deformation is observed in the Tian Shan, which is within Asia's continental interior, because Asia is not as internally rigid as the continental crust is expected to be.
Lower Himalayan Range in Tansen, Nepal with the Great Himalayas in the background. The Lower Himalayan Range, also called the Lesser Himalayas or Himachal, is one of the four parallel sub-ranges of the Himalayas. [1] [2] It has the Great Himalayas to the north and the Sivalik Hills to the south.
