Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides.
A megatsunami is a very large wave created by a large, sudden displacement of material into a body of water.
The Marcel Benoist Prize, offered by the Marcel Benoist Foundation, is a monetary prize that has been offered annually since 1920 to a scientist of Swiss nationality or residency who has made the most useful scientific discovery. Emphasis is placed on those discoveries affecting human life. Since 1997, candidates in the humanities have also been eligible for the prize.
The Französisches Gymnasium is a long-existing francophone gymnasium in Berlin, Germany. Traditionally, it is widely regarded as an elite high school. It is also the oldest public school in Berlin. Its creation was ordered by Frederick William of Brandenburg.
Ernst Heinrich Karl von Dechen was a German geologist.
Omayra Sánchez Garzón was a Colombian girl trapped and killed by a landslide when she was 13 years old.
The Frank Slide was a massive rockslide that buried part of the mining town of Frank in the District of Alberta of the North-West Territories, Canada, at 4:10 a.m. on April 29, 1903. Around 44 million cubic metres/110 million tonnes of limestone rock slid down Turtle Mountain. Witnesses reported that within 100 seconds the rock reached up the opposing hills, obliterating the eastern edge of Frank, the Canadian Pacific Railway (CPR) line and the coal mine. It was one of the largest landslides in Canadian history and remains the deadliest, as between 70 and 90 of the town's residents died, most of whom remain buried in the rubble. Multiple factors led to the slide: Turtle Mountain's formation left it in a constant state of instability. Coal mining operations may have weakened the mountain's internal structure, as did a wet winter and cold snap on the night of the disaster.
On February 17, 2006, a massive rock slide-debris avalanche occurred in the Philippine province of Southern Leyte, causing widespread damage and loss of life. The deadly landslide followed a 10-day period of heavy rain and a minor earthquake. The official death toll was 1,126.
The Vargas tragedy was a natural disaster that occurred in Vargas State, Venezuela on 15 December 1999, when torrential rains caused flash floods and debris flows that killed tens of thousands of people, destroyed thousands of homes, and led to the complete collapse of the state's infrastructure. According to relief workers, the neighborhood of Los Corales was buried under 3 metres (9.8 ft) of mud and a high percentage of homes were simply swept into the ocean. Entire towns including Cerro Grande and Carmen de Uria completely disappeared. As much as 10% of the population of Vargas died during the event.
Augusto Gansser-Biaggi was a Swiss geologist who specialised in the geology of the Himalayas. He was born in Milan.
Brienz/Brinzauls is a former municipality in the district of Albula in the canton of Graubünden in Switzerland. On 1 January 2015, the former municipalities of Alvaschein, Mon, Stierva, Tiefencastel, Alvaneu, Brienz/Brinzauls and Surava merged to form the new municipality of Albula/Alvra.
The Glarus thrust is a major thrust fault in the Alps of eastern Switzerland. Along the thrust the Helvetic nappes were thrust more than 100 km to the north over the external Aarmassif and Infrahelvetic complex. The thrust forms the contact between older (Helvetic) Permo-Triassic rock layers of the Verrucano group and younger (external) Jurassic and Cretaceous limestones and Paleogene flysch and molasse.
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists.
The 1958 Lituya Bay earthquake occurred on PST with a moment magnitude of 7.8 to 8.3 and a maximum Mercalli intensity of XI (Extreme). The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 30 million cubic meters and about 90 million tons into the narrow inlet of Lituya Bay, Alaska. The impact was heard 80 kilometers (50 mi) away, and the sudden displacement of water resulted in a megatsunami that washed out trees to a maximum elevation of 524 meters at the entrance of Gilbert Inlet. This is the largest and most significant megatsunami in modern times; it forced a re-evaluation of large-wave events and the recognition of impact events, rockfalls, and landslides as causes of very large waves.
The Flims rockslide happened about 10,000 years ago in eastern Switzerland. It is the biggest known landslide incident in the Alps, and the biggest worldwide whose effects are still visible, moving some 12 km3 (2.9 cu mi) of rock, about 300 times that of the historic Swiss Goldau landslide. The town of Flims can be found at the line where the slip surface disappears under the debris. North of Flims the rock face of Flimserstein stands 350 metres (1,148 ft) high whereas more westerly the slide surface is clearly visible. South of Flims is a huge hilly debris area that has been forest ever since, as this area is not suitable for farming, firstly for its shape and, even more for its lack of water. The river Rhine crosses this debris in a gorge called Ruinaulta. The Rhine still runs in debris, which shows that it has not yet reached the level it had before the incident. The highest hill in the debris area is almost 200 metres (656 ft) higher than Flims at the end of the sliding surface.
Schottengymnasium is an independent Catholic gymnasium with public status in the First District of Vienna. The school was founded in 1807 by imperial decree, and is considered one of the most prestigious schools in Austria. Alumni of the school include three Nobel laureates, several notable politicians, monarchs, artists and scientists.
Albula/Alvra is a municipality in the Albula Region in the canton of Graubünden in Switzerland. On 1 January 2015, the former municipalities of Alvaschein, Mon, Stierva, Tiefencastel, Alvaneu, Brienz/Brinzauls, and Surava merged to form the new municipality of Albula/Alvra.
The Katastrophenbucht is a bay on Lake Zug in the city of Zug. Its name derives from a catastrophe in a shore part called Vorstadt, in which the lake shore broke on 5 July 1887 and flooded residential buildings.
The area of Oeschinen Lake and Kander river valley in Switzerland have been subject of multiple large landslides during the Holocene. Both the number and timing of landslides is controversial, with the most recent estimates stating that the large Kander landslide occurred about 3,210 years ago and the smaller Oeschinen Lake landslide 2,300 years ago. Both may have been caused by earthquakes, and the latter landslide generated the Oeschinen Lake. More recent landslides have occurred, and unstable rock masses occur in the landslide area.
