Storms and Floods

Flooding in the Yukon River community, Alaska

At least 100 people have been evacuated due to flooding in the Yukon River community, Alaska. Two emergency shelters have been set up in Galena at the old school and the Air Force base.

Flood warnings are in effect for Galena, Hughes, and Buckland.

Landslide in Hidalgo, Mexico

Landslide in Hidalgo state in Mexico has claimed the lives of at least seven people.

Heavy rainfall and hailstorm in Tepeji del Rio caused the landslideL on a road which buried several vehicles and people when part of a hill fell down.

Flooding in Accra, Ghana

Heavy rainfall has caused flooding in Accra, the capital and largest city of Ghana.

Moss reanimates after 400 years in Deep Freeze

Ancient plants have been brought back to life, despite having been frozen inside a glacier for over 400 years.

Researcher Catherine La Farge, director and curator of the Cryptogamic Herbarium at the University of Alberta, snagged moss which carbon-dating estimated was aged between 400 and 600 years old, frozen during the “Little Ice Age” between 1550 and 1850.

The scientists picked the plants from an area around the Teardrop Glacier in the Canadian Arctic, because La Farge noticed that some of them appeared to be regrowing once the ice had retreated. Glaciers in the region have been receding at a rate of around three to four metres a year, uncovering land that hasn’t seen the Sun since the 1500s.

Once they got the plants back to the lab, La Farge and her co-authors successfully regenerated four species from the original parent material in 11 cultures from seven subglacial samples.

Volcanos

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): Etna today is free of clouds, but strong winds with gusts up to 70 km/h speed prevail. No further significant earthquakes occurred. The only activity remains degassing, and occasional small explosions, not visible, deep inside Bocca Nuova, based on seismic observations (OPEC).

Sakurajima (Kyushu, Japan): The volcano has been relatively productive with 2-4 explosions daily over the past days. Maximum ash plume heights were reported as 10,000 ft (3 km) (VAAC Tokyo).

Copahue (Chile/Argentina): Although degassing and ash emissions have decreased, seismic activity at the volcano has picked up, SERNAGEOMIN reported. An average of 356 earthquakes per hour, sometimes merging into what looks as volcanic tremor, has been recorded recently. This could be related to intruding magma from a new batch of magma rising at the moment and as a result, phreatomagmatic or magmatic activity could occur at the surface in the near future. The hazards from the volcano to populated areas are only significant in the case of a larger eruption creating a large ash plume, possible pyroclastic flows and lahars capable of travelling greater distances. Ash fall in particular would mainly threaten the areas to the east (ie. the Argentine side) because of the prevailing westerly wind directions.

Red alert for Copahue volcano

A red alert has been declared by Chilean and Argentine authorities and ordered the mandatory evacuation of a 25-km (15.5-mile) radius around the Copahue volcano. Around 2,240 people are expected to be evacuated in Chile. Similarly in Neuquen province of Argentina, some 900 people have been ordered to evacuate the area. All schools are closed in the municipality.
