The longest in history

Hello community of time this time I am writing to talk about a natural phenomenon, I have spent in the world. Never before seen in the world.
I'll tell you a little about natural phenomena first. A natural phenomenon is a change of nature that happens on its own. They are those permanent processes of the movements and transformations that nature suffers and that can influence human life; These are classified as:

• Hydrological: storms, waves, tsunamis.
• Meteorological: Floods, hurricanes, cyclones, typhoons, tornadoes, droughts, frosts, hailstorms, cold or heat waves, snow or temporary winter.
• Geophysicists: seismic and volcanic movements, avalanches, landslides, alluvium, avalanches.
Throughout history there have been a series of natural phenomena that have caused a great impact worldwide due to their magnitude of force and disaster. These are not predictable with accuracy, no country and the nation are free of any natural phenomenon for more than preventing it.
I will only take 3 phenomena that have happened previously in the world and that have been of great impact to remember a little.

1. Floods in China (1931)

3.5 million dead

They happened between July and August, and they were originated by a storm of rains and by the overflow of the Yangtze River, the largest in China. Many drowned; others, hunger or illness after the catastrophe

1. Cyclone Bhola, in Pakistan (1970)
   500,000 dead
   The strongest tropical cyclone ever presented ravaged the former East Pakistan, now Bangladesh. Winds of up to 185 km / h were recorded and only the city of Barisal lost 45% of its population.

1. Tsunami in the Indian Ocean (2004)
   280,000 dead
   It destroyed the coasts of Indonesia, Sri Lanka, India, Thailand and other Asian countries, with waves that reached 30 meters high and 12,000 kilometers away. It was so big that it caused the Earth to move 1 centimeter.
   

Today July 27, 2018, there has been a natural phenomenon called lunar eclipse, one of the longest in history and was observed in many countries is impressive to observe this type of phenomenon caused by nature
