Kobe Quake, Japan 1995

One of the world's most chaotic earthquakes happened in Kobe, Japan on Tuesday January 17, 1995 in the early morning.

It was caused by tectonic plates moving around on the earth's crust. To be exact, the Philippines Sea Plate and the Pacific sea plate were subducting (plate subduction) under each other, causing many miniscule and irrelevant tremors, and in this particular case, an earthquake. These plates are still doing this today, and will continue to do this until the end of time itself. So they will therefore continue to cause small, unnoticable quakes, and sometimes large earthquakes, forevermore.

The 1995 earthquake measured a mind-boggling 8.5 on the Richter scale, which is really VERY big. It is enormous compared to some other quakes and tremors that have previously happened, like the daily earth tremors happening near fault lines and plate boundaries all over the world. It was the worst earthquake to shake up Japan since the 1923 Kanto quake, and the Kanto quake measured around 8.4 on the Richter Scale. What is more, the many large aftershocks (of which around 408 were felt) that shook Kobe for around 9 months afterwards did not help the reconstruction of many buildings in Kobe.

The earthquake itself did not last very long at all. In fact, it only lasted a couple of seconds! To be exact, 20 seconds. But 20 seconds is still enough for an earthquake to cause MAJOR damage. And that is exactly what this earthquake did.

The epicentre of the quake was around 20 miles from Kobe, 15 miles below the island Awajisima, but the earthquake crossed those few miles extremely quickly, and it did not lose that much of it's strength at all. It was slightly weaker after all that travelling, but that simply did not make too much of a difference- it still managed to wipe out thousands of people!

Dennis Kessler, a british journalist who expierienced the eathrquake said:

"The whole room was moving around like jelly!"

From what he says, you discern that the ground had liquified by then, which proves how intense this quake really was.

The damage caused by this earthquake was amazingly vast. It took out 6434 people with it when it died down! Not to mention all the animals and such. It also managed to tear down a countless amount of buildings, so much that is cost Japan around TWO BILLION US dollars to fix it (which caused the Japan stock market to plunge downwards)! Because of that, it holds the world record for 'the most costliest natural disaster' in the Guinness Book of World Records.

It is quite common nowadays to see people praying or having a memorial service for those who lost their lives in this earthquake, and many quakes before and since. Earthquakes are a terrible thing to have to go through.

The 1995 Kobe Quake was indeed a very deadly disaster.

Report is on: The eruption of M. Vesuvius, Pompeii

When: 79AD

The eruption of Mt. Vesuvius in the year 79AD must have been devastating. No one could have escaped the horrible fate that was bestowed on them, for it came through a volcano.

(Mt. Vesuvius)

Volcanoes erupt when all the pressure underground can take no more and slowly starts to push up all the molten rock, more commonly known as magma, to the top of the volcano.

Mt. Vesuvius began forming 25,000 years ago, and has erupted many, many times since that. But above all, the most famous eruption is the one in 79AD. It completely destroyed Pompeii and many of the neighboring cities, of which the most well-known one is Herculaneum, an ancient Greek city. The eruption lasted around 19 hours, possible 18, or 20. The eruption got worse and worse, but it all started with a fume of black smoke in the sky, of which was followed by a shower of pumice falling unto Pompeii.

Pumice is a very light stone, made by volcanoes. It is only light because it has some air trapped in it, so it is able to float. However, in Pompeii. the falling of all this pumice was soon to be a problem, for much heavier rocks occasionally fell with the pumice, that would be deadly if you were hit by them. The pumice also blocked doorways, caused roofs to cave in, occasionally smashed windows and were generally a menace.

No one was safe in Pompeii, or any of the near cities, for the volcano sent many, many hardships their way. These hardships included toxic volcanic fumes, extreme heat waves and falling rocks. Everything was ruined, at the mercy of just one volcanic eruption.

(the remains of people blasted by a heat wave)

The latest eruption of Mt. Vesuvius was in 1944, but has since seemed to be dormant. Many scientests still don't believe it is dormant, yet some do.

Personally, I believe it isn't dormant, and will eventually erupt again, and cause devastation and fear everywhere.

But that is just me.
