From last some days, Delhi is suffering from earthquakes. As experts of IIT (ISM) Dhanbad’s department of applied of geophysics and seismology department said that Delhi and the National Capital Regio(NCR) may see a major earthquake in the coming days.
P K Khan, professor of the institute’s applied geophysics department said ” Recurrent tremors of small magnitudes indicate a bigger earthquake”. He also said that the time has come for the union and Delhi government to take preventive measures and create awareness.
Earthquake is a most hazardous disaster which completely destroys the region in which it occurs in a high magnitude. So the government should be aware for the next coming days to prevent the area.
Khan said ” The entire region of Delhi NCR experienced 64 tremors with magnitude ranging between 4.0 and 4.5 and eight with 5.0 and above over the last two years, which shows an increase in the accumulation of strain energy in the region, particularly near Delhi and Kangra”. 11 tremors from the total were felt in the region in the last two months with the latest near Noida on June 3.
Khan alson said ” NCR is just 370 Km from Kangra and 260 Km from Uttarkashi, which is known for severe earthquakes and a bigger earthquake in this fault line is bound to affect NCR”. The witness of earthquakes are Chamba and Dharmashala near Kangra, which has experienced earthquakes of magnitude 6.3 and 7.5 in 1945 and 1905.
Although the clustering of the recent seismicity is relatively small and apparently an area of quiescence is noted in Garhwal near Uttarkashi, it has witnessed earthquakes of 7.7 magnitude in 1803 and 6.8 magnitude in 1991. In the present times of increasing urban densification and failure of governments in making builders adhere to earthquake prevention rules, a tremor of a higher magnitude can prove to be catastrophic for the NCR, Khan opined.
He said seismicity is also being clustered along the strike of the Delhi-Haridwar Ridge (DHR) and the relative plate movement has been recorded at 44mm per year which should be a matter of concern for all.Still there is no prediction modal for earthquakes available, the Earthquake Early Warning System (EEWS) designed on previous azimuth and slowness based algorithm is a must for Delhi and NCR. Delhi government should always be alert of earthquakes. No prediction device is still found, so prevention is better idea for it.
