A Yellowstone geyser has experienced unusual eruptions lately, and scientists can't explain why


READ MORE

Geysers are the result of magma heating water that has seeped into the ground, triggering an eruption of liquid through vents in the earth surface for as long as dozens of minutes, followed by billowing steam that may last days.


Yet geysers are difficult to study. Most have unpredictable eruptions that may happen in intervals lasting years, making it challenging to assign resources such as seismic monitors and cameras, Poland said. For instance, no scientists observed Friday’s eruption. It was reported by a visitor, he said.


Poland said he is not sure what is exactly going on with the Steamboat geyser.


One possibility he offered: the three eruptions on March 15, April 19 and Friday could point to thermal disturbances – heated ground that can change the behaviour of geysers and springs or form new ones, he said.


The string of eruptions over a year in 2003 may have been connected to a particularly violent thermal disturbance that killed trees and nearly boiled trails in the Norris Basin, where several geysers, including Steamboat, are located.

Dwayne Leverock : Famous for his one-handed catch at the 2003 World Cup, the 130kg Bermudian would surely make just as big a splash on the rugby field. Jofra Archer runs in to bowl  Get...

Banned Bancroft's journey of self-discovery

Image
READ MORE © Getty Images Spanish lessons, yoga and a host of community work have all been part of the path taken by Cameron Bancroft since the Newlands ball-tampering scandal. The Australia batsman has been looking to seek the sort of perspective and self-knowledge that will prevent him from following the kind of instructions issued to him by David Warner in the Cape Town dressing room. Bancroft spoke in Perth on Saturday ahead of his return to cricket via Twenty20 and 50-over appearances in the Northern Territory, where he will also endeavour to work closely in developing local talent. It’s the next step on the path away from Newlands as Bancroft serves a nine-month ban from the game imposed by Cricket Australia under its code of conduct. Perspective on life was greatly needed as Bancroft, Warner and the former captain Steven Smith pondered what evolved in South Africa, and Bancroft said he had spent plenty of time devoting himself broadening his own knowledge and also to...

Drones to become the new naval mine hunters under Morrison pledge

Image
READ MORE Advanced navies worldwide are increasingly turning to drones to do mine hunting and clearing work at sea. Marcus Hellyer, a former Defence Department official and now a senior analyst at the Australian Strategic Policy Institute, said that using autonomous and unmanned sea vehicles allowed the crewed ship to stay at the edge of a minefield, keeping naval personnel safer. The Morrison government has promised if re-elected to fast-track the building of two new mine hunting naval ships. Credit: Nine Newspapers “Common sense has prevailed,” he said of the decision. “Rather than keeping going down the path where you have old technology being extended at great cost, this will introduce new technology more quickly and that’s a good thing. “The current path does keep the human at the centre of the minefield, but the new approach lets them stay outside the minefield and let autonomous vehicles go in and do the dangerous work.” Article source: https:/...
