Interesting Images

A new image reveals how water flows through every river basin in the United States.

The stunning visualization follows the path of blue gold throughout the country. Surprisingly, no area is too far from the path of water. For instance, the arid Southwest may go months without significant rainfall, yet most of the region is threaded by hundreds of rivers fanning out from the Upper and Lower Colorado Rivers.

Wildfires

Wildfires – Australia

Firefighters are working to manage more than 50 fires across NSW, as their focus turns to an out-of-control blaze in Port Stephens in the Hunter region.

The fire is burning in the area of Karuah, Balickera, Limeburners Creek and Swan Bay, and has burnt 6,500 hectares. During the day hundreds of firefighters worked to control the blaze, which was burning along an 80-kilometre front, and water-bombing aircraft joined the battle.

A bushfire that threatened to destroy homes in Sydney on Friday, has burnt through bushland in the suburb of Cranebrook, 65 km (40 miles) west of Sydney’s central business district. On Saturday (November 5) a 16-year-old was arrested by police for deliberately lighting the fire, after two people were arrested for the same blaze in Cranebrook. Combined high temperatures and strong winds saw bushfires burning in the suburb of Castle Cove in Sydney’s north.

Disease

Avian Influenza (H5 and H7 strains) in birds in Europe

The Hungarian authorities have confirmed HPAI H5N8 in a (wild) Mute Swan by a lake in Csongrad region, a well-known rest place for migratory birds at this time of year. This is the first report of HPAI H5N8 this year in the EU and follows the case in wild birds in Central Russia reported in June 2016. The same subgroup or clade (2.3.4.4) of H5 viruses was also detected in USA (Alaska) in August 2016 in wild mallards.

In other unrelated disease reports, the Netherlands has confirmed an outbreak of low pathogenic avian influenza, H5 (N type not determined) in turkeys in Deurne, Limburg. The holding contained approximately 12,000 turkeys, 5,000 ducks and 2,000 pheasant; no clinical signs were observed. The birds have been depopulated. The four other premises in the 1km zone have been screened.

In an unlinked incident, the German authorities reported an outbreak of LPAI H7N3 in captive birds in Mannheim on 18th October. Disease was detected in pheasants and a further 52 birds (ducks, guinea fowl and peacocks) were humanely destroyed.

Volcanos

Roundup of Global Volcanic Activity

Turrialba (Costa Rica): The volcano’s activity has been fairly constant over the past weeks. It continues to erupt near-constant ash and steam plumes reaching up to 500-1000 m height and drifting into various directions (mostly to the west). Light ash falls regularly affect downwind areas. The activity, at fluctuating intensity, seems to be mostly driven by the magma-water interaction (phreatomagmatic activity), caused by a (probably small) body of new magma underneath the shallow hydrothermal system.

Sinabung (Sumatra, Indonesia): An explosion this morning produced an ash plume that rose 1500 m and a small pyroclastic flow of 700 m length. This shows that the supply of magma continues even though most of the recently emplaced dome has disappeared during past week’s collapse events.
