Earthquake, Uttarakhand - Current Affairs Questions and Answers

1)   Scientists have found which phenomenon changes elastic properties of earth’s crust close to 6,000 kilometres away?

a. Earthquakes
b. Hurricanes
c. Typhoons
d. Cyclones
Answer  Explanation 

ANSWER: Earthquakes

Explanation:
Earthquakes can be the cause of changes in earth’s crust close to 6,000 km away, changing the ability to tolerate stresses for a new weeks, according to researchers. Scientists have found that the earth is interconnected and dynamic whereby one large, massive earthquake can create cascading sequence of events 1000s of km away. While the surface wave from the earthquake passing through another fault region causes frictional properties that ensure surfaces are locked together, elasticity allows crust to withstand strain and stress state can lead to failure. While surface waves pass through, the properties rearrange and change. This discovery was made by examining the 2012 earthquake off the coast of North Sumatra in the Indian Ocean.
The earthquake, which had a magnitude of 8.6, is known to have been followed by two earthquakes in Japan with a magnitude greater than 5.5.

3)   With how many countries is India working on an ambitious project with scientists, geophysicists, and seismologists to develop an early-warning system for prediction of earthquake?

a. 5
b. 15
c. 27
d. 32
Answer  Explanation 

ANSWER: 27

Explanation:
The warning could be issued some seconds before the earthquake strikes. An official release issued by Ministry of Earth Science said, India is also planning to launch a satellite to track the changes that take place on earth's surface before the tremors.
