Natural Disaster fourth most powerful earthquake in the world

BY HAFIS APIS

First, how many of you know about natural disasters? What I know is a natural disaster is a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life. In Malaysia we face the flood, heavy rain and equinox but other countries face the other things. Actually, I want to explain about Volcano, Tsunami, and Flood.

Volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.

In Hawaii, Mauna Loa is an active volcano and is due for an eruption. Mauna Loa has erupted 15 times since 1900. These eruptions have lasted from a few hours to 145 days. Since 1950, Mauna Loa has erupted only twice, in 1975 and 1984.

According to Ken Hon, a volcanologist at the University of Hawaii at Hilo. He has found many, many more explosions than we thought existed.

In Malaysia, we never face the volcano eruption.

Tsunami is also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.

A Tsunami usually happens after an Earthquake underwarter. Because of vibration at the land that’s why it affects the sea.

In 2011 in Tohoku, Japan their face the worst natural disaster. It was earthquake and tsunami. According to Wikipedia on Friday 11 March 2011, with the epicenter approximately 70 kilometres east of the Oshika peninsuola, Tahoka and the hypocentre at an underwater depth of approximately 30 km. The earthquake is also often referred to in Japan as the Great East Japan earthquake and also known as the 2011 Tahoka earthquake, and the 3.11 earthquake. It was the most powerful earthquake ever recorded to have hit Japan, and the fourth most powerful earthquake in the world since modern record keeping began in 1900. The earthquake triggered powerful tsunami waves that reached heights of up to 40.5 metres in Miyako in Tahoka’s Iwate Prefecture, and which, in the Sendai area, travelled up to 10 km inland. The earthquake moved Honshu (the main island of Japan) 2.4 m east, shifted the Earth on its axis by estimates of between 10 cm and 25 cm , and generated infrasound waves detected in perturbations of the low-orbiting GOCE satellite.

Tsunami in Malaysia happened 12 years ago in Pulau Pinang. According to Awani Astro Channel it was the first time tsunami happen in Pulau Pinang. Apparently, it was a side-effect from Indonesia’s Tsunami.

A flood is an overflow of water on land which is usually dry. Sometimes a river receives too much extra water, either from heavy rain or other natural disasters. When this happens, the water overflows from its normal path in the river bed and onto dry land. This is called a flood. Flash floods happen quickly.

The World's Worst Flood – 1931. Flooding in China in 1931 killed as many as four million people, and left 80 million homeless. It was preceded by a three year drought and heavy snow/rain. Atmospheric CO2 levels were 310 ppm, well below Dr. Hansen's “safe” level of 350 ppm.

Malaysia also facing the flood disaster.                                        

Based on my experience the natural disaster that I faced is flood at Kelantan. In December 2014 the worst flood happen in Kelantan. According to the council’s report, the water level of Sungai Kelantan at Tambatan DiRaja, which has a danger level of 25 metres, reached 34.17 metres last month compared to 29.70 metres in 2004 and 33.61 metres in 1967.

In 29 December 2014 many citizens in Kelantan loss their home and stuff. Some of them cannot control their emotional. Some of them just “Redha”  what happen to them.

Natural disaster can happen anywhere, it depends on our God where he wants to put he is power.
