How the disaster that has claimed the lives of more than 200 people in Indonesia has happened

The disaster in Indonesia, the slope of the volcano collapsed, and the tsunami wave was created. how the disaster that has claimed the lives of more than 200 people in Indonesia has happened.

More than 200 people have been killed in a tsunami that struck beaches in Indonesia's sunda region. Researchers believe that the tsunami is linked to sub-marine landslides caused by the eruption at Anak Krakatoa.
How such a phenomenon can occur? The volcanic eruption does not in itself create a tsunami. What happens is that a slope is formed on the fringes of the volcano. 

When a slope reaches a certain height, it becomes unstable. If it happens underwater, then there is an underwater surfing of the material, the margin of the mountain falling down, and this causes a particular wave that causes a tsunami.
Almost all the islands of Indonesia began as volcanoes.
Can such a disaster repeat itself?  This is not unique to Indonesia: "There are more such islands across the oceans - like in the Canary…

Measurements of material transition from Saturn's rings suggest the rings will disappear in 100m years

The Rings of Saturn 
New measurements of material transition from Saturn's rings to the planet itself suggest that the rings are likely to disappear completely in less than 100 million years
The rings around the planet Saturn are one of the most prominent symbols of the solar system, but a new study led by scientists from the US space agency (NASA) reveals that the rings are disappearing at an accelerated rate and may disappear completely within 100 million years - a short time in cosmic terms.

Saturn is surrounded by eight main rings, from about 70,000 miles to 170,000 kilometers. The width of the rings can reach thousands of kilometers, but are only 20 meters or less, and are mostly made up of ice crystals of various sizes - some microscopic and others can reach several meters.

Some of the crystals contain dust or simple organic molecules, which give the rings their characteristic shade. The planet itself, like most of the solar system, was formed about 4.5 billion years ago.

NASA`S Voyager program Spacecraft Voyager 2 Begins Interstellar travel

While the probes have actually left the heliosphere, Voyager 1 as well as Voyager 2 have not yet left the planetary system, as well as will not be leaving anytime quickly.

The limit of the planetary system is thought about to be past the external side of the Oort Cloud, a collection of little things that are still drunk of the Sun's gravity.

The size of the Oort Cloud is not understood specifically, yet it is approximated to start at around 1,000 huge systems (AU) from the Sun and also to reach regarding 100,000 AU. One AU is the range from the Sun to Earth.

It will certainly take around 300 years for Voyager 2 to get to the internal side of the Oort Cloud and also perhaps 30,000 years to fly past it.

Along with the plasma information, Voyager's scientific research staff member have actually seen proof from 3 various other onboard tools-- the planetary ray subsystem, the reduced power billed bit tool as well as the magnetometer-- that follows the verdict that Voyager 2 has actu…
