Earth Changes
Actually, this volcano is the remnant of the biggest blast ever recorded on Earth. That was the 1883 eruption of Mount Krakatoa. From the ruins of that gigantic crater left in the land has come forth what is now known as the Anak Krakatau volcano - literally "Krakatoa's Child."
In the time since the original eruption, scientists have gotten much better at predicting when a volcano will have a catastrophic eruption, distinguishing it from the many smaller eruptions which do not harm the local population or environment.
One of the telltale signs is sudden and increased activity like what scientists are seeing in this past week at the Anak Krakatau volcano.

A worker uses a high-pressure washer on the roof of a home while carrying out decontamination work in Fukushima in October.
The city began decontamination work in the Onami district on Oct. 18. Located in the mountains in the eastern part of the city, it has been heavily affected by the Fukushima nuclear disaster, with radiation in rice over the nation's provisional limit of 500 becquerels per kilogram detected, leading to a ban on rice shipments.
Although monitoring of six homes where decontamination was carried out found an average drop of 70 percent in radiation in front of entrances and on gravel parking spots, there was only a 30 percent drop for roofs and a 25 percent drop for asphalt in the yard. Furthermore, there was only a 22 percent drop for second floor interiors.
The city has suggested that the low effect on the roofs may be due to radiation from the surrounding forests, where decontamination has not been carried out. As for the asphalt, radioactive material tends to stick to it and remain even after being washed, so the city has decided to try removing the top layer of the asphalt.
A magnitude-6.1 quake struck Thursday evening south of the northern island of Hokkaido, Japan's Meteorological Agency said.
It hit about 465 miles (750 kilometers) northeast of Tokyo and 19 miles (30 kilometers) below the sea surface. The agency did not issue a tsunami warning.
About 3,900 households in the towns of Erimo and Samani lost electricity shortly after the quake, but power was restored about an hour later, according to the Hokkaido Electric Power Co.
The shaking was not felt in Tokyo, though a morning quake was.
That magnitude-6.0 temblor struck just off the coast near the nuclear power plant damaged by the March 11 earthquake and tsunami.
The two shakings are believed unrelated and did not affect the crippled Fukushima Dai-ichi plant or other nuclear plants in the region.

The sinking brine is so cold that it causes the seawater to freeze around it.
BBC film crews recorded the brinicle for the first time ever as it sunk to the bottom of the sea in Antarctica.

The icicle of death: The brinicle can be seen extending towards the seabed. Slowly it grows bigger over time as more water freezes around it
The remarkable underwater footage was filmed for Frozen Planet on BBC One using timelapse technology.

Giovanni Long, 16, told khou.com that he fell several feet and was under water for about 15 seconds as he tried to claw his way out of a hole 6 feet deep and 10 feet wide as he was walking in Kleinwood, a suburb northwest of downtown Houston.
"Everything beneath me crumbled," he told the website after the Monday afternoon incident. "I didn't know what to do."
"I was trying to dig my way out of the hole, but the ground kept breaking back into me," added Long, who finally got out with a few scratches on his back and a sprained ankle. "It's funny now that I think about it ... but when it happened, it was actually scary."
Why the 12-inch water line broke wasn't determined, but it's possible that recent rain after months of drought caused the ground to shift.
The drought itself caused daily water main breaks across Houston.

A climate study has found increasing fluctuations between cloudy days and sunny ones, and between dry days and downpours. Above, an example of one extreme.
The world isn't just warming, in parts of the planet the weather is becoming more erratic, new research indicates.
By looking at measurements of sunlight striking the planet's surface as well as precipitation records, a study has found that in certain places, daily weather is increasingly flip-flopping between sunny and cloudy, and downpours and dry days. It's not yet clear why this is happening.
This is the first global climate study to examine variation in day-to-day weather. So far, climate science has focused on extremes - record temperatures or intense storms, for example - or on averages, such as estimates that global temperatures have risen 0.7 degrees Celsius (1.3 degrees Fahrenheit) since the Industrial Revolution.
"I think it turns out day-to-day variability is actually important and perhaps more attention should be paid to it," said David Medvigy, the lead researcher and an assistant professor in the department of geosciences at Princeton University.
This is because increases in weather fluctuations have important implications, particularly for plants - which currently pull about 25 percent of the greenhouse gas carbon dioxide emitted by humans out of the air.
