Tornado touches down at Denver International Airport

This Tuesday, June 18, 2013 image provided by Scott Morlan shows a tornado that touched down near Denver International Airport.
Radar indicated a tornado briefly touched down Tuesday over the east runways of Denver International Airport, where thousands of people took shelter in bathrooms, stairwells and other safe spots until the dangerous weather passed, officials said.

Airport spokeswoman Laura Coale reported no damage. Nine flights were diverted elsewhere during a tornado warning that lasted about 40 minutes, she said.

A 97 mph wind gust was measured at the airport before communication with instruments there was briefly knocked out, said National Weather Service meteorologist Kyle Fredin.

Chris Polk, a construction foreman, was working on a renovation project just outside the airport's main concourse when he got the tornado warning at 2:15 p.m., looked up and saw a funnel cloud. He and his crew ran inside and took shelter with some 100 people, including luggage-toting passengers, inside a basement break room as tornado sirens sounded.

"It got pretty crazy around here," Polk said.

Asked whether he was nervous when he spotted the funnel cloud, he shrugged. "No, I'm from Missouri," he said.

Everyone inside the break room was calm, Polk added.

Huge 'dead zone' predicted in Gulf of Mexico

Dead Zone

Areas with low levels of oxygen are referred to as dead zones. Red areas correspond to less oxygen.
A very large dead zone, an area of water with no or very little oxygen, is expected to form in the Gulf of Mexico this year - a trend in recent years, according to the National Oceanic and Atmospheric Administration (NOAA).

Computer models put together by scientists predict that the zone will cover an area between 7,286 and 8,561 square miles (18,871 to 22,173 square kilometers) this summer, the typical time for such zones to form. The large end of the estimate is roughly the size of the state of New Jersey, and would be the largest dead zone ever recorded. The biggest one recorded to date, in 2002, reached 8,481 square miles (21,966 square km).

Meanwhile, models predict the dead zone in the Chesapeake Bay will be smaller than usual.

Manam volcano erupts in Papua New Guinea

An eruption with a small ash plume was reported this morning and VAAC Darwin issued an advisory. A low level ash plume was also visible on Nasa's Aqua Modis image at 15:45 UTC. This is the volcano's second eruption this year. The volcano unleashed an ash cloud in early January. - Volcano Discovery

Yet another mysterious mass fish die-off in North America - Temple, Texas

Temple Community Puzzled Over Dead Fish Pond


It's a mystery that has people in Central Texas scratching their heads.

Hundreds of fish turning up dead in a Temple pond this weekend.

When lifelong Temple angler Eloy Machuca came to Miller Park today he saw something he didn't expect.

"I come down here to release some fish, usually little ones so kids can catch them, but I've never seen this many," Machua said.

What he saw were dead catfish hundreds of them.

"I would say 90 percent of them are dead."

Florida: Indian River Lagoon mystery ailment killing dolphins, manatees, pelicans


The Indian River Lagoon on Florida's east coast has long been known as the most diverse ecosystem in North America.

Its 156 miles of water boast more than 600 species of fish and more than 300 kinds of birds.

The lagoon is not just an ecological treasure. To the towns along its edge - Titusville, Cocoa, Melbourne, Vero Beach and Stuart, among others - it accounts for hundreds of millions in revenue from angling, boating, bird-watching, tourism and other waterfront activities.

But these days the Indian River Lagoon has become known as a killing zone.

Algae blooms wiped out more than 47,000 acres of its sea grass beds, which one scientist compared to losing an entire rainforest in one fell swoop.

Then, beginning last summer, manatees began dying. As of last week, 111 manatees from Indian River Lagoon had died under mysterious circumstances. Soon pelicans and dolphins began showing up dead too - more than 300 pelicans and 46 dolphins so far.

Dead fish reported at Milford Reservoir, Salina, Kansas

Don Phillips and Larry Riat were both amazed and perplexed about a week ago when they fished at Milford Reservoir.

The amazing part included a massive run on channel catfish as they fished from a boat, using jig lures.

What alarmed and perplexed the 76-year-old retirees was the thousands of dead carp and other less desirable species in the water and on the shore.

"There were two dead carp about every foot. They were floating in the water about everywhere," said Riat, of Abilene.

The channel catfish were spawning, said Phillips, of Salina.

"We caught many, many of them and turned them back," he said. "They were good eatin' size."

The pair were after walleye and crappie. They caught a few crappie, but turned them back.

But what they wondered about most was the dead carp.

Why the dead carp?

Fisheries officials at the lake have been fielding reports about dead fish -- 99 percent of them carp -- for a couple of weeks, starting from the north end, said R.J. Harms, Milford operations manager for the U.S. Army Corps of Engineers.

Violent explosion shakes Mexico's Popcatepetl volcano

Mexico's active Popocatepetl volcano has registered a massive explosion spewing ash and incandescent rock almost 4 kilometers high. Authorities have warned that winds could blow the ash cloud as far away as Mexico City. Inhabitants of villages up to 25 kilometers from Popocatepetl (colloquially known as 'Don Popo') rushed out of their houses when the massive explosion reverberated through their homes. Esther Matinez, resident of Amecameca municipality, told Mexican publication La Jornada that the blast was like a rocket explosion. Around 4.5 million people live within a 50-kilometer radius of the active volcano, 650,000 of whom are considered to be at high risk.

Massive section of ocean floor off the coast of Portugal beginning to fracture

A new subduction zone forming off the coast of Portugal heralds the beginning of a cycle that will see the Atlantic Ocean close, as continental Europe moves closer to America. Published in Geology, new research led by Monash University geologists has detected the first evidence that a passive margin in the Atlantic Ocean is becoming active. Subduction zones, such as the one beginning near Iberia, are areas where one of the tectonic plates that cover Earth's surface dives beneath another plate into the mantle - the layer just below the crust. Lead author Dr João Duarte, from the School of Geosciences said the team mapped the ocean floor and found it was beginning to fracture, indicating tectonic activity around the apparently passive South West Iberia plate margin. "What we have detected is the very beginnings of an active margin - it's like an embryonic subduction zone," Dr Duarte said.

Strong 5.8 earthquake sways buildings in Mexico City

Image
A powerful two-punch earthquake shook western Mexico early Sunday, knocking out electricity and cellular phone service in parts of this sprawling capital. There were no immediate reports of serious damage or fatalities. Initial readings put the quake at a magnitude of 5.8 at around 12:30 a.m., with the epicenter about 90 miles south of Mexico City in the northern part of Guerrero state, where Acapulco is located. It was felt with marked strength in Mexico City, swaying major apartment buildings, hotels and skyscrapers. Residents scooted from their homes, some in pajamas, or filed out of late-night bars and restaurants. Many remained in the streets long after the quake ended, bracing for aftershocks. The shaking began gently, paused, then gave a good rattling to buildings in much of the capital.

Mexico City Mayor Miguel Angel Mancera, whose inspectors immediately took to flight in helicopters and fanned out through city streets, said there were no reports of serious damage but that several neighborhoods were without electricity. Interior Minister Miguel Angel Osorio Chong also said there were no reports of damage at the national level. Mexico is accustomed to such quakes, and a fairly strict system of checks and controls whips into place at the first sign of serious shaking. In 1985, parts of the Mexican capital were destroyed and at least 10,000 people were killed in a devastating quake. - LA Times
