Roundup of Global Volcanic Activity

Nevado del Ruiz (Colombia): The volcano produced again several small to moderately-sized ash eruptions during yesterday and today, generating plumes that rose up to approx. 1 km above the crater. The most significant emissions occurred occurred yesterday morning at 08:22 and today at 07:48 local time and were accompanied by a strong tremor signals.

Dallol (Danakil desert, Ethiopia): Help us protect Dallol and have it listed as UNESCO World Heritage Site by contributing to an ambitious and very interesting crowd-sourced project: Dallol is located in the northern Danakil desert of Ethiopia, at the bottom of the African rift. It is a salt dome with a unique and bizarre array of colorful geysers, hot springs, acid lakes and mineral pools encrusted with sulphur and various salt crystals. It is not a volcano in the strict sense, but a very active hydrothermal area that results from the interaction between the salt water from the Red Sea, evaporation deposits and heat from an underlying magma chamber, hidden beneath more than 2 km of salt. This geological and biological heritage is now threatened by a large-scale mining industry plans. World-renowned photographer and director Olivier Grunewald is working on a documentary in order to raise awareness among the Ethiopian authorities and beyond, to urge them to apply for its nomination as a UNESCO World Heritage Site.


Wildfires – California – Update

Search dogs checking neighborhoods incinerated by a 6-day-old wildfire in the Sierra Nevada haven’t found any more bodies, leaving the death toll at two, fire officials reported.

After burning nearly 73 square miles of brush and grass, the blaze was 60 percent contained. Winds that might push the fire were light, and crews continued to protect homes and carve a fire line. Inspectors tallied 257 homes and other buildings destroyed and 17 damaged. More than 1,800 firefighters were on the lines and firefighting costs reached $13 million.

Northeast of Los Angeles, two adjacent fires in the San Gabriel Mountains above foothill suburbs collectively covered 8½ square miles. The San Gabriel Complex was 72 percent contained nine days after the fires erupted. With 481 firefighters on the lines, high temperatures and oppressive humidity from the latest early season heat wave were a concern.

In far northwestern California, a 4½-square-mile fire in Klamath National Forest was 63 percent contained. The fire has been burning 15 miles southwest of Happy Camp in Siskiyou County.

East of San Diego and west of Santa Barbara, fires that each charred more than 11 square miles, were near full containment.

A 1-square-mile blaze that scarred the U.S. 395 community of Lee Vining in Mono County and smaller fires in Orange, San Luis Obispo and Lake counties were 50 to 85 percent contained.

Residents of a rural subdivision 50 miles northeast of Sacramento were evacuated as a wildfire climbed out of a steep canyon along the Middle Fork of the American River and approached homes near the Todd Valley community between Foresthill and Auburn.

Wildfires – Nova Scotia

Crews were battling several wildfires in wooded areas throughout the Nova Scotia on Tuesday, the provincial government said.

Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

Tropical cyclone (tc) 02a (Two), located approximately 248 nm east of Masirah Island, is tracking south-southwestward at 02 knots.


Pakistan – Rain related incidents in Quetta, Pakistan has claimed the lives of at least four people including two children and injured more than 20 others on Monday. A flash flood collapsed the boundary walls of Sandeman Civil Hospital and dozens of mud houses have collapsed and been damaged in slums and downstream areas of the city.

Philippines – At least 1,400 families or close to 7,500 individuals evacuated to higher ground when their homes in the towns of Matalam and Kabacan in North Cotabato were flooded early Tuesday dawn. The Kabacan and Pulangi Rivers swelled and overflowed to low-lying villages. Moderate to heavy rains caused the rivers and other waterways to overflow and send runoff to residential and vast agricultural areas in the low-lying villages of the town. hundreds of hectares of newly planted rice fields were also submerged in flood water.


Light pollution is causing spring to arrive a week early

Light pollution has another side-effect, it can push spring to emerge a week earlier in cities than in the country, a new study has found.

Trees were in bud an average of seven-and-a-half days earlier in well-lit areas than in dark spots. The early budding may cause problems for insects, which feed on leaves, and the birds which then feed on them in turn.

Sycamore, ash, oak and beech trees were all found to bud early under the influence of artificial light. Light had a more significant effect than temperature on when buds emerged, the scientists found.

Caterpillars are timed to hatch to make the most of opportunities to feed from freshly budded leaves, and birds hatch in time to feed off the young caterpillars. If this cascade effect is thrown out of sync, then wildlife is bound to suffer.

The amount of artificial light produced at night is growing by 6 per cent annually, the researchers say. Street lights have been found to confuse many species that prefer dark conditions, such as moths and bats.
