Earthquake swarm hits South Reno, Nevada - More than 230 quakes and counting

South Reno earthquake swarm
South Reno has been shaking, ever so gently, for six days now.

If you live there - near Galena High School or where the Mount Rose Highway goes below the I-580 - you likely haven't felt much, if anything. But earthquake detecting instruments in the area have picked up more than 230 small temblors since late last Thursday.

The largest in the swarm so far, which hit Tuesday afternoon, measured a 2.7 on the Richter scale - a magnitude that University of Nevada, Reno seismologist Ken Smith described as "pretty small."

"You'd have to be right above it to really feel anything," he said, noting they've gotten a few dozen reports from people who've felt the jolts.

While earthquakes in Northern Nevada are commonplace (The Silver State is the third-most seismically active state in the nation), Smith said he and his colleagues at UNR's Nevada Seismological Laboratory pay special attention to earthquake swarms.

Comment: In recent months we have seen other areas of the US experiencing these swarms of mini-earthquakes as well:

Heavy snow and snapping trees concern forest owners in Norway

Forest owners in Norway say they are concerned about damage to trees and subsequent loss of earnings caused by heavy snow .

"We can no longer be sure of stable winters," forest owner Thor Wraa told broadcaster NRK.

A week of extreme weather with heavy snowfall in several parts of the country has caused significant disruption, with fallen trees dragging down telephone wires and blocking roads.

Wraa, who comes from the northern Telemark county, told NRK that falling trees directly affected his livelihood.

"We are concerned. Trees with as much snow as there is now are right on the limit of breaking or falling," he said.

Over a meter of snow dumps on the Alps in 72 hours, with another meter forecast over next 3 days

snow
A number of ski areas in the Alps have reported up to 1.3m (over four feet) of snowfall in the past 72 hours and forecasters are expecting up to 1.3m (over four feet) of snowfall in the next 72 hours.

All the snow is good news for resort bases, but less good for skiers and boarders in resort at present, or travelling out tomorrow, Saturday 20th January, as ski areas are only able to open limited terrain safely, conditions are frequently poor even in those limited open areas , and travel to and from resorts can be difficult.

Austria's Ziller Valley is reporting 1.2m (four feet) of snow in the past 72 hours with Verbier reporting 105cm and the Portes du Soleil region up to 90cm (three feet) of snow. Many other resorts including Crans Montana, Davos, Laax, La Plagne and Zermatt have had 60-90cm of new snowfall.

High winds, big waves batter west coast of Vancouver Island, Canada (swells of up to 9.5 metres)

Several beaches, including those in Pacific Rim National Park, were closed Thursday as the west coast of Vancouver Island was hit with high winds and swells of up to 9.5 metres.

CTV reports that they were some of the largest waves seen on the west coast of Vancouver Island in a decade - possibly the largest ever.

"Mostly, it's the danger of the water," Randy Mercer of Parks Canada told CHEK News of the decision to close the beaches. There's a risk of being knocked down and dragged out by the waves, or being struck by floating logs, he said.

Over 100 Olive Ridley turtles found dead along coast in Tamil Nadu, India

Over the past week, more than a hundred Olive Ridley turtles have washed up dead on the beaches of Chennai, and many more are believed to be floating dead on Bay of Bengal.

Over the past week, more than a 100 Olive Ridley turtles have washed up dead on the beaches of Chennai, and many more are believed to be floating dead on Bay of Bengal.

The endangered Oliver Ridley turtles, well-known for their coordinated nesting in large numbers, generally make their annual trip up the Bay of Bengal during the breeding months of December and January. However, the use of trawlers and gill nets have historically resulted in sweeping up these sea turtles and drowning them. They are also increasingly consuming plastic waste in the ocean.

Endangered right whale's calving season peaks, but no young seen

Scientists watching for baby right whales off the Southeast U.S. coast have yet to spot a single newborn seven weeks into the endangered species' calving season, a dry spell researchers haven't seen in nearly 30 years.
Scientists watching for baby right whales off the Southeast U.S. coast have yet to spot a single newborn seven weeks into the endangered species' calving season — the longest researchers have gone without any sightings in nearly 30 years.

Bad weather that has limited efforts to look for whales could be to blame, rather than a reproductive slump. But scientists also worry it could point to another low birth year for the imperiled whales after a grim 2017, when 17 confirmed right whale deaths far outpaced a scant five recorded births.

"We basically right now should be at the peak of the season and we haven't seen anything, so that's concerning," said Clay George, a wildlife biologist who oversees right whale surveys for the Georgia Department of Natural Resources. "I'm going from being the optimist I normally am to being pretty pessimistic about it."

Unusual weather triggered 2015 mass death of quarter million saiga antelopes in Kazakhstan, study says

Humidity and hot temperatures triggered the deaths of more than 200,000 endangered saiga antelopes in Kazakhstan over the course of three weeks, researchers say.

The May 2015 deaths were caused by hemorrhagic septicemia triggered by a bacteria known as Pasteurella multocida Type B, which dwells in the respiratory tract of the animals, according to a study on the event.

"The animals were in a sort of foggy soup, and it looks like the bacteria naturally occupying the tonsils were woken up by this environmental factor," Royal Veterinary College professor of wildlife health and emerging disease Richard Kock told The Washington Post.

Comment: Strangely enough, no one knows for sure why flu viruses appear in winter. Some say that viruses thrive in low humidity because they remain suspended in the air longer, but humidity can be very high in wintertime in many places. Maybe these bacteria and virii are in our bodies all the time and only activate during certain atmospheric conditions. Maybe some bugs need a 'key' to turn them on? Like some other virus or something in the atmosphere?

On Jan. 18th, the Japanese space agency JAXA launched a small rocket from the Uchinoura Space Center. It made a big display. Japanese artist and photographer Kagaya captured dramatic images of the rocket's exhaust glowing in the starry pre-dawn sky over the Pacific:

"I watched the launch from Okinawa Island and photographed it using my Sony α7RIII camera," says Kagaya, who has posted a must-see video of the event on Youtube.

Hundreds evacuated as ice jams cause flooding in USA and Canada (PHOTOS)

Ice jams have caused severe problems along some rivers in north eastern USA and eastern Canada since 12 January, 2018. States of emergency have been declared and around 200 people have evacuated their homes and north eastern USA and a further 100 in New Brunswick, Canada.

Heavy rain over the last few days has also caused rivers to overflow and some surface flooding. Two people died in West Virginia when their vehicle was trapped in flood water. Flood rescues were required in Pittsburgh after a major road was flooded.

Ice jams in northeastern USA

Media have reported dozens of ice jams along rivers in north eastern USA. Below is a short summary of some of the floods.

Parts of the Connecticut River near Haddam are so blocked, ice breakers from the US Coast Guard have been called in to break the jam.

Loud explosion in southern Wisconsin rattles homes, 'knocks things off walls'

Law enforcement officials Thursday afternoon were investigating an explosion in a field north of Janesville that was linked to a noise dozens of residents reported hearing Thursday morning.

Leon Brown, who lives next to the property where the explosion occurred, said a vehicle exploded around 9:30 a.m. Photos taken at the scene show the remains of what appears to be an obliterated vehicle.

Rock County 911 Communications Center Director Kathy Sukus said officials were investigating the incident in connection with the explosion noise and shaking houses in Janesville, Milton and Edgerton reported earlier.

Reporters at the scene Thursday afternoon saw several law enforcement officials and vehicles in a field north of the intersection of North Kennedy and East Manogue roads. A lone law enforcement vehicle with a trailer was spotted several dozen yards southwest of the officials.
