Mainstreaming the Northeast in India’s Look and Act East Policy by Atul Sarma download in iPad, ePub, pdf
Growing industrialisation and unjustified exploitation of natural resources have brought our echo system to a verge of non-reversibility and imbalance. The ground floor is generally used for parking and walls start from the first floor.
But with suitable calibration with actual gauge measurements correction factors could be applied. Another approach is to estimate the probabilistic occurrence of an earthquake statistically by relating the past occurrences to weather conditions, volcanic activity and tidal forces. Aftershocks are earthquakes that often occur during the days and months that follow some larger quake. The location of the epicentre of a quake is determined from the time of arrival of the P and S waves at the seismographic station. As such, it is extremely subjective.
One method developed by the Americans involves the use of laser beams. On hitting the satellite, the waves are reflected back to the observatory. The phenomenon that really ought to engage the minds of planners is how and why the flood-prone area in the country is increasing each year.
Coastal inundation due to a combination of high tide and storm surge can cause the worst disaster. India has an efficient cyclone warning system. The data is transmitted acoustically to a surface buoy which then relays it over satellite to the warning centre.
Cattle and goats also destroy the plant cover that springs up after the rain which is crucial for holding down the soil. But for the people there it is a traumatic experience. More new posts will be added below this one. The waves of very, very long wavelengths and period rush across the ocean and increase their momentum over a stretch of thousands of kilometers.
As an average ocean depth of m is assumed, one talks of tsunamis as having an average speed of about km per hour. Again, a marine volcanic eruption can generate an impulsive force that displaces the water column and gives birth to a tsunami. The greatest damage in an earthquake is caused by the destruction of buildings and resultant loss of life and property and destruction of infrastructure.
The entire north-eastern region falls in zone V. But the Holocausts do not prove that Whites are worse than other people, just that they are no better. As a result the increasing siltation of rivers is accelerating their rate of flow in flood, eventually forcing even well built embankments to give way. Afforestation in the catchment areas, along the river banks, helps in maintaining the effective river volume. This has not helped much as population has moved into areas where flooding used to occur and has been controlled due to structure.
