Nepal earthquake 2015

With the whole country in unrest and pandemonium due to continued earthquake attacks in Nepal since April 25th, there have been many hushed conversations. Why is such devastating natural disaster striking Nepal repeatedly? What is its cause? Had it been predicted before? Is Nepal the only epicenter of this 7.9 Richter scale rated earthquake?

While some out there claim that this disaster has its wings well spread from Los Angeles to Japan, the most reliable reason till now has been the movement of tectonic plates. Tectonic plates are pieces of the Earth’s crust and uppermost mantle. It consists of sima (silicon and magnesium) and sial (silicon and aluminium). The Indian tectonic plate is moving north at about 45mm a year and is pushing the Eurasian plate beneath the Himalyas.

The most amusing, or intriguing thing (depends on how you perceive it) is that earlier, weather patterns were earlier thought to be linked to earthquake patterns. Hot and humid, oppresive climate, with lots of clouds overhead and sun shining bright from behind. It was usually termed as a typical earthquake weather.

To set an example, here are some snaps I took on 25th April, the day of the major earthquake.

Now, anyone would put two and two together to come to the conclusion as mentioned above. Though the coincidences are too many to rule them out, scientifically there is no base of this assumption. A general study of the pattern and occurrences of earthquakes show they occur in all seasons and temperatures.

Quoting an article that I found online, “While weather patterns may not cause earthquakes, they may influence the amount of damage caused by one. Prior to the 1906 San Francisco earthquake, several months of heavy rain had caused the ground beneath structures to become soft, translating to greater shaking of buildings and more overall damage. The rains didn’t cause the earthquake, but they made its result more severe.”

Bursting the myth that weather changes can predict earthquakes, I would like to conclude although weather patterns may not be the reason, thermal temperature seem to emerging as a better predictor of earthquakes. But still they are not certified as hundred percent reliable scientifically.
