Why the nation is becoming so frequent to Earthquakes
A tremendous earthquake recently hit the Coast of New Britain Island in Papua
New Guinea with the magnitude measuring 6.9. The earthquake was strong but it
did not caused any casualties as the epicenter was quiet far from the port which
was 35 km (21 miles) deep in the sea between New Britain Island and Papua New
Guineas north coast.
The data collected by US government’s National Oceanic and Atmospheric
Administration suggest that the frequency of earthquakes occurring year by year is
increasing extensively but its intensity is decreasing as we don’t see earthquake of
high level occurring that often.
The last disaster that striked the South Asia Regions was in 2015 when most of the
parts of Nepal were devastated completely due to an earthquake ranging 7.7 hitting
the city taking lives of more than nine thousand people and about 22 thousand
were injured in the same.
It seems Earth is no more a safe place to live. The recent study done by Japanese
Professor of Seismology showed that, “The Indian subcontinent is operating with a
speed of five-cm-a-year towards the sea and it is just a common natural
phenomenon. So in every five to six years, the plates in Earths crust have to adjust
with changes in this disenchanted geographical region. Nepal Earthquake is a
consequence of one such phenomenon."
According to USGS (US Geological Society),225 million years back from now
India was situated so close to Australia but due to the movement in the plates
inside the crust made India travelled more than 6400 km to crash into Eurasia
about a 55 million years ago which resulted in the formation of Himalayas.
UGC feels, the reason of Nepal earthquake was due to this only as Nepal border
shares a boundary with Eurasia and Indo-Australian plate tectonics. Once these
dishes meet and create pressure, the stress is released in the form of earthquake.-WTN
