2021 Uttarakhand Avalanche
The 2021 Uttarakhand flood, also known as the Chamoli disaster, began on 7 February 2021 in the environs of the Nanda Devi National Park, a UNESCO World Heritage Site in the outer Garhwal Himalayas in Uttarakhand state, India (Maps 1 and 2). It was caused by a large rock and ice avalanche consisting of material dislodged from Ronti peak. It caused flooding in the Chamoli district, most notably in the Rishiganga river, the Dhauliganga river, and in turn the Alaknanda—the major headstream of the Ganges (Maps 2 and 3). The disaster left over 200 killed or missing. Most were workers at the Tapovan dam site. Cause According to early reports, the flooding was speculated to have been caused by a portion of the Nanda Devi glacier breaking off early on 7 February, releasing the water trapped behind the ice, and causing a glacial lake outburst flood. But this was shown to be incorrect as satellite images showed no lakes in the valley and that a landslide very clearly ...

Ganges
The Ganges ( ) (in India: Ganga ( ); in Bangladesh: Padma ( )). "The Ganges Basin, known in India as the Ganga and in Bangladesh as the Padma, is an international river to which India, Bangladesh, Nepal and China are the riparian states." is a trans-boundary river of Asia which flows through India and Bangladesh. The river rises in the western Himalayas in the Indian state of Uttarakhand. It flows south and east through the Gangetic plain of North India, receiving the right-bank tributary, the Yamuna, which also rises in the western Indian Himalayas, and several left-bank tributaries from Nepal that account for the bulk of its flow. In West Bengal state, India, a feeder canal taking off from its right bank diverts 50% of its flow southwards, artificially connecting it to the Hooghly river. The Ganges continues into Bangladesh, its name changing to the Padma. It is then joined by the Jamuna, the lower stream of the Brahmaputra, and eventually the Meghna, forming the major ...

Hanging Glacier
A hanging glacier originates high on the wall of a glacial valley and descends only part of the way to the surface of the main glacier and abruptly stops, typically at a cliff. Avalanching and icefall An icefall is a portion of certain glaciers characterized by relatively rapid flow and chaotic crevassed surface, caused in part by gravity. The term ''icefall'' is formed by analogy with the word ''waterfall'', which is a similar phenomenon of t ...s are the mechanisms for ice and snow transfer to the valley floor below. Rock and icefall from a hanging glacier was responsible for triggering the Kolka-Karmadon rock ice slide in 2002, which killed 125 people. References Glaciology {{Glaciology-stub ...

Planet Labs
Planet Labs PBC (formerly Planet Labs, Inc. and Cosmogia, Inc.) is an American public Earth imaging company based in San Francisco, California. Their goal is to image the entirety of the Earth daily to monitor changes and pinpoint trends. The company designs and manufactures Triple-CubeSat miniature satellites called Doves that are then delivered into orbit as secondary payloads on other rocket launch missions. Each ''Dove'' is equipped with a high-powered telescope and camera programmed to capture different swaths of Earth. Each ''Dove'' Earth observation satellite continuously scans Earth, sending data once it passes over a ground station, by means of a frame image sensor. The images gathered by ''Doves'', which can be accessed online and some of which is available under an open data access policy, provide up-to-date information relevant to climate monitoring, crop yield prediction, urban planning, and disaster response. With acquisition of BlackBridge in July 2015, Planet La ...

Nanda Devi
Nanda Devi is the second-highest mountain in India, after Kangchenjunga, and the highest located entirely within the country (Kangchenjunga is on the border of India and Nepal). It is the 23rd-highest peak in the world. Nanda Devi was considered the highest mountain in the world before computations in 1808 proved Dhaulagiri to be higher. It was also the highest mountain in India until 1975, when Sikkim, an independent kingdom until 1948 and a protectorate of India thereafter, became a part of the Republic of India. It is located in Chamoli Garhwal district of Uttarakhand, between the Rishiganga valley on the west and the Goriganga valley on the east. The peak, whose name means "Bliss-Giving Goddess", is regarded as the patron goddess of the Garhwal and Kumaon Himalayas. In acknowledgment of its religious significance and for the protection of its fragile ecosystem, the Government of India declared the peak as well as the circle of high mountains surrounding it—the Nanda ...

Satellite Image
Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world. Satellite imaging companies sell images by licensing them to governments and businesses such as Apple Maps and Google Maps. History The first images from space were taken on Sub-orbital spaceflight, sub-orbital flights. The U.S-launched V-2 flight on October 24, 1946, took one image every 1.5 seconds. With an Apsis, apogee of 65 miles (105 km), these photos were from five times higher than the previous record, the 13.7 miles (22 km) by the Explorer II balloon mission in 1935. The first satellite (orbital) photographs of Earth were made on August 14, 1959, by the U.S. Explorer 6. The first satellite photographs of the Moon might have been made on October 6, 1959, by the Soviet satellite Luna 3, on a mission to photograph the far side of the Moon. The Blue Marble ...
