Palghar: Scientists at National Center for Seismology are puzzled by mysterious seismic ripples that have been recorded by the Permanent Seismological Observatory in Palghar district, Maharashtra since November 11, 2018. More than 10 earthquakes of magnitude more than 3 have occurred in the Talsari Taluka and the largest magnitude earthquake of 4.1 was recorded today preceded by three earthquakes of magnitude 3.0 and above on the same day.
A 2-year-old girl died in an earthquake when three earthquakes measuring 4.1, 3.6 and 3.5 on the Richter scale hit the district today at 2:06 pm, 3:53 pm and 4:57 pm respectively.
According to a statement released by NCS, all these earthquakes were followed by numerous aftershocks of very small magnitude. To monitor this strange earthquake activity NCS installed a temporary field station at Vedanta hospital, Dhundhalwadi village followed by two more temporary field stations were installed at Dongripada and Talasari.
According to NCS, earthquakes of small magnitudes categorised as “Earthquake swarm” have occurred for long period (3-4 months) on several occasions in central western India.
“No proven scientific technique is available in any part of the world, to predict the future earthquakes precisely with regard to space, time and earthquake magnitude. Hence the civil and housing structures are to be properly engineered as per the earthquake-resistant building codes specified by the Bureau of Indian Standards (BIS),” National Center for Seismology report stated.
Officials from NCS and Indian Meteorological Department (IMD) interacted with the locals in the earthquake affected region and advised them on Do’s and Don’ts.
Last year in November, seismic waves triggered sensors from Africa to New Zealand and Hawaii for around 20 minutes; however, according to a report by National Geographic, no one felt the bizarre ripple.
