Ring seen around the sun in eastern Virginia

While it doesn't happen every day, we are occasionally treated to a funky sky phenomenon of a halo around the sun or moon.

This ring is caused by cirrostratus clouds, which are made of ice crystals. They are found above 20,000 feet. They can get quite thick, but sun or moon light can be seen through them.

This light is refracted through the ice crystals, and this causes the halo. At times, the clouds can be very thin and hardly visible until the halo is shown.

We often see cirrostratus clouds increasing ahead of a front or storm system. Thursday afternoon's halo was caused by moisture being thrown into our area by the remnants of Tropical Depression Cindy.

Rincón de la Vieja volcano eruption blasts over 2000 meters in Costa Rica


Blasts at Costa Rica's Rincón de la Vieja Volcan
The National University's Volcanology and Seismology Research Institute (OVSICORI), reported an eruption at the Rincón de la Vieja Volcano in Guanacaste at 2:56 p.m. this Friday, June 23, where the column reached 2000 meters above the crater and 3,916 meters above sea level, (12844.48 ft).

According to the report by OVSICORI, the eruption registered is phreatomagmatic, which means it results from the interaction between magma and water. This type of eruptions usually contains juvenile magmatic clasts.

The activity was short, only lasting one minute, There are no reports of ash-fall for the time being, but the explosive and violent eruption caused once again a small pyroclastic flow, meaning a current of hot gas and volcanic matter such as rocks that heads down the north slope of the volcano forming a lahar. The lahars that form as a product of eruptions in this volcano usually affect the rivers Pénjamo, Azul and Quebrada Sufrosa.

Volcanologists recommend staying away from these rivers since the water level can increase suddenly.

Shallow earthquake measuring 5.8 magnitude strikes Beira, Mozambique

An earthquake measuring 5 point 8 magnitude struck 60 kilometers (37 point 28 miles) northwest the Mozambique city of BEIRA, the United States Geological Survey said today.

The USGS put the depth of the tremor at 10 km (6. 21 miles).

The USGS says Mozambique lies on a huge East African continental rift that is associated with shallow earthquakes. The most recent major quake to strike the region took place in Mozambique in 2006. It measured magnitude 7.0 and killed two people.

A strong earthquake with a preliminary magnitude of 6.5 has struck Botswana, with shaking felt across southern Africa, including South Africa, Mozambique, and Zimbabwe on April 32017

At least three tornadoes and a microburst hit Quebec in one day; 'It's quite unusual' says Environment Canada

The tornado that hit the Saguenay region Sunday on Lac Kénogami travelled as fast 180 kilometres an hour and hit a class 2 on the Fujita scale, according to Environment Canada meteorologist Marie-Ève Giguère.

Cyclones carved kilometres-long paths near Lac St-Jean and Mont-Laurier


Three tornadoes touched down in Quebec last weekend — all in one day.

Environment Canada confirmed in a statement that "at least three tornadoes and a microburst affected the province" Sunday.

"It's quite unusual," meteorologist Marie-Ève Giguère told CBC News Wednesday.

"On average in Quebec, we confirm about six tornadoes every summer, so three on the same day is definitely a rare occurrence."

The tornadoes carved paths several kilometres long in the Lac St-Jean and the Mont-Laurier regions, as well as the Laurentides Wildlife Reserve between Quebec City and the Saguenay.

Two of the tornadoes - the ones in Lac St-Jean and near Mont-Laurier - hit Class 2 on the Fujita scale, meaning their winds reached 180 kilometres per hour.

Landslide buries more than 100 people in China after torrential rain

Massive search efforts are underway in China's Sichuan Province after a landslide destroyed dozens of houses, reportedly burying at least 100 people underneath the rubble.

Torrential rain in Maoxian County triggered the large landslide which destroyed around 40 households in Xinmo Village, Xinhua reports. Around 100 people are feared trapped underneath the dirt and debris.

The disaster happened in the Tibetan and Qiang Autonomous Prefecture and struck at around 6:00am local time.

Some 500 people are now part of the search and rescue efforts after authorities mobilized manpower and deployed resources, including excavation equipment, to save the trapped villagers.

The landslide has also blocked about a two-kilometer section of a local river course.

"Something must be attracting them": Thousands of harp seals surround Russian drilling rig in Arctic Circle

An enormous herd of harp seals has occupied every free ice floe as far as the eye can see around Russia's Prirazlomnaya offshore oil drilling rig located in the Pechora Sea, inside the Arctic Circle.

"I've never seen anything like this. There are thousands of them!" says an astonished oil rig worker, who did not wish to identify himself, during a minute-long video that was sent to the Russian explorer and travel writer Sergey Dolya, who posted it on his blog.

Harp seals migrate annually between their birthing and feeding grounds and the Arctic, where they spend the summer, often traveling in excess of 4,000 km in large colonies.

Dangerous dog attacks rocket across Lancashire, UK; 70% increase in 2 years

2BR has got hold of figures showing dangerous dog attacks have increased by 70% in two years.

We asked Lancashire Police to tell us how many of these incidents they investigated.

In 2014, they recorded 162 dangerous dog attacks.

But the year after, that had shot up to 499.

Last year, they had to investigate 545 incidents involving dangerously out of control dogs

Seismologists study massive Yellowstone earthquake swarm

Seismologists are studying a swarm of 500-plus earthquakes that have rattled the Yellowstone Park area since June 12.

Most are centered 8 miles north-northeast of West Yellowstone. That is just a few miles east of the Hebgen Lake Basin, the site of the historic 1959 quake. That one measured 7.3 on the Richter scale, killed 28 people and created Quake Lake, near the Gallatin National Forest.

Mike Stickney, of the Earthquake Studies office at Montana Tech, said earthquake swarms are normal this time of year. He says many are smaller. When we checked we found dozens that measured under 2.0 on the Richter scale.

Mysterious orange water seen at Dubai Marina

The waters of Dubai Marina turned orange on Thursday.
The waters of Dubai Marina mysteriously turned orange on Thursday.

Residents were quick to share their concerns on social media suggesting that an oil spill could be responsible for the change in colour.

A spokesperson from Dubai's Municipality said they had not yet identified the cause and a team of officials had been sent to inspect the site on Friday morning.

"There are some speculations that the spillage can be from a near by construction or from groundwater", the spokesperson said.

Residents said the water was still strangely coloured on Friday morning.

Three cliff falls in just two days near iconic Seven Sisters, UK; woman killed


A sightseer was just feet away from death as 50,000 tons of chalk gave way and a cliff collapsed into the sea in East Sussex
A sightseer was just feet away from death as 50,000 tons of chalk gave way and a cliff collapsed into the sea, claiming the life of a woman in her 20s.

The cliffs at Seaford Head in East Sussex have been hit by three unexpected collapses in just two days.

The first happened on Wednesday afternoon, taking a huge section of the coastline with it. Yesterday afternoon there was another collapse, before a giant crack tore into an 80ft chalk-face leading to the third cliff fall last night.

Now photographs have emerged of people peering over the edge of Birling Gap, which is roughly six miles from where the cliffs collapsed at Seaford yesterday.

Rescuers yesterday found the body of a woman in her 20s who is believed to have fallen from a clifftop around the time of the dramatic rockfall.

And as the Coastguard has issued a warning urging people to avoid the area, photographs have come to light which show a person teetering near the edge despite the imminent danger.
