The volcanic explosion in 1883 caused most of Krakatoa to collapse into the sea and these islands were the land masses that remained above sea level.
A fourth island, named Anak Krakatau (meaning 'child of Krakatoa") was formed after a volcanic eruption in 1927. It sits over one of the three active volcanic vents that were once part of Ancient Krakatoa and continues to have minor eruptions to this day.
Events Leading up to the Explosion of KrakatoaThe earliest signs of activity were detected by commercial trading ships who reported an eight-mile plume of smoke in late May, 1883. This was a result of minor eruptions from the Perboewetan volcano on the island of Krakatoa.
As the months went by, there was an increase in ash fallout and chunks of pumice were found on the islands in the area. As these eruptions were occurring, the caldera on Perboewetan was widening and more pressure was building underwater.
The first sizable blast of Krakatoa occurred in the early afternoon on August 26th, 1883. The volcano spewed a 15-mile high column of dark volcanic gas and it generated a shockwave which was felt in the neighbouring islands of Sumatra and Java. More explosions occurred which increased in intensity and sent the gas plume higher into the atmosphere.
Volcanic material started to spill down the flanks of the volcano. The effects of the blasts generated a series of tsunamis which destroyed coastal villages on several islands in Indonesia.
The Explosion of Krakatoa August 27th, 1883The first of four catastrophic explosions occurred at 5:30am on August 27th, 1883. An increasingly thick blanket of pumice and ash enveloped the neighbouring islands. Tsunamis of 100 feet high caused more damage along shorelines.
The second blast occurred at 6:44am and it repeated the effects of the first blast. The third blast at 10:20am was the most intense of the four. Two-thirds of Krakatoa sunk into the caldera which was sitting at 750 feet below sea level. The last blast at 10:52am was not as intense but it perpetuated the damage.
The Effects of the Explosion of KrakatoaA research paper published by The Department of Physical Geology at Earlham College, reported; "In total, 23 square kilometers of the island fell into the 6km wide caldera. The ground shook in the wake of the blast which was heard over 4500km and was estimated to be equal to the detonation of over 21,000 atomic bombs."
Pyroclastic flows spread over the Sunda Strait and affected the coastal areas of Sumatra where thousands of residents were killed immediately by the blast of hot gases.
Powerful tsunamis hit the shores of the Indian ocean, similar to the killer tsunami that occurred on December 26th, 2004 when a very strong earthquake ruptured the ocean floor near the west coast of Sumatra, Indonesia.
According to the Department of Geological Sciences, San Diego State University, "These tsunamis stripped away all vegetation, washed ~30,000 people out to sea, and destroyed all signs of human occupation."
The final death toll was estimated at 36,417. source:

How Do Krakatoa Look Like?
The nearby islands of Java and Sumatra are heavily forested with occasional towns. The small islands that remain of the original Krakatoa are also forested. Some trees grow around the new volcanic island of Anak Krakatau has some trees around the edges but is mostly covered in ash and volcanic rock.
How a child can stay safe during volcano eruption?
die or look on google
What do dormant sleeping volcanoes look like?
It may be bigger, smaller, or even practically nonexistent afterwards, depending on the volcano and type of eruption it had.Some volcanos build themselves up with additional layers of lava and/or ash.Some volcanoes blow away large parts of themselves, shrinking in size.A few volcanoes can explode so violently that nothing is left after an eruption.
What did mount saint helens look like after the eruption?
A large portion of one side of the mountain was blown away. Trees were blown down for miles, and much of the land was buried under volcanic ash.
What word means a mountain with a crater?
Found on mountains, calderas look like volcanic craters that were left from an eruption, however they are not actually volcanic craters. The word comes from the Latin caldaria, meaning cooking pot.
what did the 1883 eruption of Krakatoa look like?
It had island features.
What did the eruption look like?
That depends on which eruption you're talking about.

What does the mint mark on the 1883 silver dollar look like?
For this year the mintmarks can only be "S" "O" and "CC" or no mintmarks. No Morgan dollar will have a "P" mintmark like modern coins.

What caused yellowstones eruption?
Yellowstone's last eruption was approximately 620,000 years ago, and therefore the precursory events are not well understood. As to what causes any volcanic eruption the answer can be simple or complex depending on which way you look at it. If you look at it from the simple way it is as follows: pressure within the magma chamber exceeds the pressure of the earth holding it in causing an eruption. As per the complex way of what events actually triggered an eruption of this size is poorly understood. It is however more than likely that it was not one single trigger for the eruption but a combination of different things as the magma chamber approached critical that allowed it to break through causing the super eruption.

What do avalanches look like?
An avalanche is like a giant snow eruption, like a huge hurricane or tornado of snow. It's very dangerous, and isn't a great thing to be standing near to. To see what an avalanche can look like in full blow, go on a video website, and type in 'Avalanches'. Pick any one which looks like a giant hurricane of snow.
