Natural catastrophes- dark forces of nature

Natural disasters come uninvited and wash out everything that comes in the way [or you can say "and wash away everything in their way]. The world has been prone to natural catastrophes that have taken the lives of hundreds of thousands of people. Recently, an earthquake hit Nepal a week ago, the worst in the past eight decades that has claimed the lives of more than 6,200 people, leaving 20,000 displaced while the death toll still continues to rise, and rescue teams are busy in digging amongst the rubble to save people trapped inside/under the rubble. The magnitude of the earthquake recorded/scaled on the Richter scale was found to be 7.8. Nepal is suffering from the worst a terrible humanitarian crisis: the shortage of food and scarcity of clean water exposes the quake-affected people [or you can say "quake victims"] to diarrhea and gastric diseases. Time is running short, Nepal is in dire need of humanitarian assistance that includes rescue workers, tents, food, water and doctors. Neighboring countries, India, and China, including and Pakistan have stepped up in this very hour of need and sent out the teams of rescue workers, medical staff and planes [to deliver supplies]. The Nepalese President has urged the UN and the whole world to help out Nepal in curbing recovering from the effects of the worst natural catastrophic crisis [or "natural disaster"] of the 21st century. Heavy rains and series of aftershocks following the earthquake have traumatized the people, and people they are afraid to go back home. Heavy rains have caused landslides that slowed down the process of rehabilitation. Avalanches on the world’s highest peak have killed almost 20 ill-fated tourists, who came had come for on an expedition to reach the summit.

This was a great read!  A few notes:
– I've suggested other ways to say some things, highlighted in pink. Your way of saying it is not wrong, but my suggestions may make the write-up flow more smoothly :)
– Remember what I told you about using extreme words? Saying the quake was "the worst humanitarian crisis" is not safe. You may however, say "the worst humanitarian crisis of the decade so far" (if you really feel very strongly that it is the worst so far in this decade!)
– The word highlighted in blue means something slightly different from your intended meaning (I think).
"Curbing" means "restraining", so whatever you are restraining has to be still happening. The earthquake is over, so you cannot say "curbing the earthquake" and there is no such phrase as "curbing from". A better way to say what (I think) you mean is "recovering/recuperating from the effects of the earthquake/etc."

Hope this helps! Great job as always. Keep it up! :) 

Natural catastrophes- dark forces of nature

Natural disasters come uninvited and wash out everything that comes in the way. The world has been prone to natural catastrophes that have taken lives of hundreds of thousands people. Recently, an earthquake hit Nepal a week ago, the worst one to have hit  in past eight decades which has claimed the lives of more than 6,200 people leaving 20,000 displaced while the death toll still continues to rise, and rescue teams are busy digging rubble to save people trapped under the ruble. The magnitude of THE earthquake recorded on the Richter scale was found to be 7.8. Nepal is suffering from the worst humanitarian crisis, a shortage of food and scarcity of clean water which exposes disease and leaves the vulnerbale to diarrhea. Time is running out, Nepal is in dire need of humanitarian assistance that includes rescue workers, tents, food, water and doctors.

Neighboring countries, India and China, including Pakistan have to step up in this very hour of need and sent out the teams of rescue workers, medical staff and planes.
