FLOOD IN BANGLADESH.

Flood is a natural calamity.Bangladesh fall victim to this flood every year.During flood men and other animals suffer untold miseries. After flood various diseases like diarrhoea and cholera break out in an epidemic from.So flood is a serious problem for our country.

The south asia country of banglagesh is prone to the natural disaster of flooding due to being situated on the ganges delta and themanytributaries flowing into the bay of bengal. The coastal flooding twinned with the bursting of Bangladesh's river banks is common and severely affects the landscape and Bangladeshi society. 75% of Bangladesh is less than 10m above sea level and 80% is flood plain, therefore rendering Bangladesh a nation very much at risk of further widespread damage despite its development, especially as its present flood defenses are unsustainable and somewhat amateur. Flooding normally occurs during the monsoon season from June to September during the monsoon. The convectional rainfall of the monsoon is added to by relief rainfall caused by the Himalayas. Meltwater from the Himalayas is also a significant input and flood every year.

THOUSAND MAROONED ACROSS COUNTRY IN BANGLADESH.

Incessant rain couplet with tidal surges since wednesday disrupted normal life and business throughout the country and left several thowsand people marooned.

The  rain and tidal surges washed away many thstched houses and caused river erosion in many areas,especially in the coastal districts of cox's bazar, bagerhat, satkhira and patuakhali.

Sufferings of the poor in these districts have intensified as the rainwater and swelling rivers flooded crop fields and washed away shrimp enclosures with tidal surges danaging many embankents.

Heavy rainfall also led to water logging at different parts in capital city.

DEADLIEST EARTHQUAKES IN THE HISTORY.

An 8.9-magnitude earthquake has hit northeastern japan, producing a destructive tsunami that swept through 

 several coastal areas.Here we have tried to look at some of history's most unforgiving earthquakes.

A quake struck central China in January 1556, estimated at around magnitude 7.9, killing approximately 820,000 people. Hundreds of thousands of people living in artificial caves built into cliffsides were crushed when landslides destroyed their homes. Despite the high toll, it is only the third-worst natural disaster in history – the other two being floods, both also in China.

 Tangshan, China

The deadliest quake of the 20th Century occurred in eastern China, July 1976. It killed 250,000, though initial estimates were almost three times that number. The area worst-affected was thought to be low risk for quakes, and buildings were not built to withstand strong tremors. Strange animal behaviour was noted before the shaking – the city's dragonflies reportedly left in the days leading up to the quake, and fish were seen trying to leap out of their aquarium

The Chinese State Seismological Bureau even issued a warning to the region a few weeks beforehand that a quake was likely. One county took note, and the UN later concluded the death toll could have been a lot higher if preparations had not been made. Kanto, Japan

A 7.9 quake shook the Kanto region of Japan in 1923, an area encompassing Tokyo and Yokohama, both of which were devastated. The quake hit in the middle of the day when many people were cooking with fire. Winds spread the flames quickly, and a broken water mains system formed a deadly combination with an offshore typhoon, resulting in firestorms which burned tens of thousands alive. Others got stuck in melting tarmac or were swept away by landslides and tsunamis. Around 100,000 were confirmed killed and 40,000 missing, for a likely total around 140,000.

In addition to the toll exacted by the quake, typhoon, firestorms and tsunamis, over 6,000 Koreans were murdered after rumours spread they were looting and deliberately setting fires.
