Carla Zeus.
I was just at a Friday last week and I'm happy to report its awesome Thank you so much for making CNN 10 part of your Friday.
Our international coverage starts in Australia, where there's been some good news and some bad news.
Then more good news.
Let me explain.
New South Wales is a state in south eastern Australia.
It was the hardest hit state by the Bush fires we reported on earlier this year.
Though every Australian states been affected by them, it's summer there now when the country typically sees a fire season.
But this one was made worse by an ongoing drought.
Tens of millions of acres burned.
At least 28 people have been killed, about 3000 homes have been destroyed and millions, possibly hundreds of millions of animals have been affected.
So what's good in all that?
Well in New South Wales, it could be coming to an end.
Fire officials say all of the wildfires there have been contained, meaning some are still burning, but they've all been surrounded and stopped from spreading.
Firefighters say it's been a traumatic, exhausting and anxious Bush fire season so far, but that the containment of the blazes will allow emergency workers to now focus on helping people rebuild.
Okay.
More bad news.
A tropical cyclone recently rolled along the coast of New South Wales.
It brought damaging winds, dangerous waves and it caused major flooding.
The storm's heavy rains led to the evacuation of several towns.
Many schools in the region closed, and there are severe thunderstorms in the forecast for the days ahead.
But the good thing about the cyclone, which is what Hurricanes air called in the South Pacific, is that it's helped put out more than 30 fires since last Friday.
The New South Wales Rural Fire Service called that the most positive news they've had in some time.
Second trivia.
What is the largest gulf in the world?
The person golf Gulf of Aden, Gulf of Mexico or Gulf of Alaska.
Covering around 600,000 square miles, the Gulf of Mexico is the world's largest massive oil slick, now covering some 600 square miles of the Gulf of Mexico, and it could start reaching the United States coast within hours.
Wait, wait.
Still unknown, but possibly worse than what was originally thought.
It's been almost 10 years since the deepwater horizon oil spill occurred, and a new study suggests that invisible and toxic oil might have made the spill 30% bigger than it was originally estimated to be.
The reason, according to this study, is that satellites observing the Gulf of Mexico might not have been able to detect all of the oil that actually spilled.
Researchers say that the three dimensional computer simulations that they used indicated that Maura oil and smaller concentrations actually resulted from the spill.
They say that satellite data is still the fastest and most accurate way to find oil slicks, but that in the future, new technology can help better assess how widespread they are.
BP did not comment on the study.
One of the most active volcanoes in Indonesia is erupting once again.
Mount Merapi fired ash thousands of feet into the air yesterday as lava bled down from its crater.
No one was hurt, but tourists and residents were told to state two miles away from the volcano's peak, Mount Merapi is closely watched to the region because 10 years ago it had a major eruption that killed more than 300 people and forced hundreds of thousands to evacuate the area.
Officials say that from December to January of this year, volcanic activity from Mount Merapi had increased above and below the surface.
Volcanic eruptions have devastated communities for centuries, killing tens of thousands of people around the world.
The haunted Mountain of Papua and You're Gonna Burst, interruption, majestic and menacing, begins its slow rumbling and relentless journey down to the towns and villages that awaited inevitable Coming with.
With about 1500 volcanoes on Earth, it's no wonder we worry about thes mountains of molten rock.
But why did they erupt?
More than 80% of the Earth's surface above and below sea level is volcanic and deep below.
The Earth's tectonic plates are always moving.
Most volcanic activity occurs where these plates collide deep within the Earth.
It is so hot that rock slowly melt and become magma.
Because this flowing substance is lighter than the rocks around it, it rises when some of these tectonic plates shift, the magma rises, even hire.
Some of the magma pushes through the cracks in the earth's crust advance and at Fisher's, reaches the surface where it is that called lava.
What kind of eruption the volcano will have depends on the properties of the magma.
Thin and running Margaux means gas trying to escape conduce so easily.
When this happens, the lava will flow out of the volcano.
We've seen this with Hawaii's volcanoes because the lava flows slowly, people can get away quickly, and it rarely results in victims.
But thick and sticky magma is a different story.
There's less room for gases to escape, and the pressure mounts.
Gas gets trapped in the magma, which then explodes at the surface.
This is called an explosive eruption, and we've seen it with Mount Etna in Sicily and Mount ST Helens in the U.
S.
Explosive volcanic eruptions can be dangerous and deadly lava, ash and debris can destroy everything in their path.
In some cases, these eruptions have buried entire communities like Mount Vesuvius and Pompeii and Mount Pelee, Martinique.
About 500 volcanoes have erupted since we started keeping records.
Many around the Ring of Fire, an area from New Zealand's to the coast of South America, where there are the most subduction zones.
Plate movements, all volcanic activity is closely monitored by scientists around the world.
By tracking active volcanoes, experts can see the warning signs and alert the public before an eruption for 10 out of 10.
How to train a sheep dog to become a bird dog.
There are a lot of geese in the area around Denver, Colorado, and after seeing his dog chase geese away from a campsite, the owner decided to use the animal in goose control.
And that's become a full time job, he says.
The dogs don't actually eat or even contact the geese, but they make them think that there's a predator in the area so the birds won't come back.
Or should I say they won't come?
Beak.
They will come park now you might be thinking waterfowl idea.
When a dog has a good gander at a goose and goes on a wild goose chase, the Geest it's got to do is geese out of there in a dog on hurry before it gets hearted, though not hurt it by a border collie turned border collie tie OGA.
