The steep scarp rises 100–200 m (330–660 ft) from the sea, and extends towards the western base of the cone, at 900 m (3,000 ft) beneath sea level, where it also spreads out to 4 km (2.5 mi) across. [7] The volume of material lost to the collapse remains a contentious topic with various figures estimated. Ritter Island remains active; minor ...
Emotional accounts from relatives of the victims and survivors of the partial collapse of a boat dock gangway on Georgia’s Sapelo Island and a newly released video of the frantic rescue efforts ...
Giant landslides and collapses of ocean island volcanoes were first described in 1964 in Hawaii and are now known to happen in almost every ocean basin. [1] As volcanoes grow in size they eventually become unstable and collapse, generating landslides [2] and collapses such as the failure of Mount St. Helens in 1980 [3] and many others. [4]
Two thirds of the island collapsed into the sea after the event. [68] Groups of human skeletons were found floating on pumice numerous times, up to a year after the event. [69] The eruption also generated what is often called the loudest sound in history, which was heard 4,800 kilometres (3,000 mi; 2,600 nmi) away on Rodrigues in the Indian Ocean.
Ritter Island is a small crescent-shaped volcanic island 100 kilometres (62 mi) north-east of New Guinea, situated between Umboi Island and Sakar Island. There are several recorded eruptions of this basaltic-andesitic stratovolcano prior to a spectacular lateral collapse which took place in 1888. Before that event, it was a circular conical ...
Authorities are investigating the cause of a partial ferry dock collapse on Georgia’s Sapelo Island that turned a day of celebration into tragedy, leaving at least seven dead and six critically ...
The Guanche language word jameo refers to a large opening in a lava tube, which is formed when parts of the roof collapse. Both Jameos del Agua and Cueva de los Verdes are located inside the volcanic tube created by the eruption of the Monte Corona volcano. The tube is 6 km long, of which at least 1.5 km is located below sea surface, and is ...
Collapse: How Societies Choose to Fail or Succeed (titled Collapse: How Societies Choose to Fail or Survive for the British edition) is a 2005 book by academic and popular science author Jared Diamond, in which the author first defines collapse: "a drastic decrease in human population size and/or political/economic/social complexity, over a considerable area, for an extended time."
