As 3 major earthquakes shake the world during a span of 72 hours, many apprehend some big temblor is due anytime soon.
On Friday (February 13), Delhi and its adjoining areas were hit by a huge jolt measuring 6.3 on Richter scale , with its epicenter in Tajikistan.
Accessing things , senior geologists stress upon having a correct disaster management decide to affect any emergency, because it isn’t possible to predict quakes.
Starting with a huge undersea quake hitting north of latest Zealand on February 11, 2021, which was measured to be of seven .7 magnitude on a Richter scale , prompted a tsunami alert within the region.
The Geological Agency informed that the quake was centered at a depth of 10 kilometers southeast of the Loyalty Islands. Following the quake, the US Tsunami Warning Centre confirmed that a tsunami is probably going to strike the coastal areas of latest Zealand and Australia.
The next day, a 6.3 magnitude earthquake epicentered in Tajikistan was felt at various locations in North India. The tremors from the quake were felt for quite 30 seconds within the capital .
While the planet was only gathering information on these two previous quakes, Japan was hit by a 7.1-magnitude quake, which was epicentered near Fukushima. The tremors were felt for over 90 seconds and brought back memories of the 2011 tsunami. albeit no deaths were reported within the earthquake, over 100 were injured.
As per the Japan Meteorological Agency said the earthquake was centered about 60 kilometres (37 miles) beneath the ocean bed.
The tremors were also felt within the capital Tokyo where an intensity scale of 4 was logged, with many reporting that their houses and furniture underwent strong shaking and a few saying they felt dizzy due to the quake.
Now because the world stands still the fear of something big approaching grips everyone. is that this the silence before the storm?
Dr. Soumitra Mukherjee, Professor of Geology at Nehru University asserted that there are changes within the earth before an earthquake, hence the changes are often assessed.
“Before the earthquake within the earth, the natural vegetation either dries up or becomes very green. It are often detected with high resolution through satellites. A normalized differential weighting index are often used. Interferometry may be a subject during which it are often detected by remote sensing whether there has been a change of 1 or two millimeters tall at anywhere on earth … If it’s come then it are often evaluated with the state of the art remote sensing method. But the matter is that this method isn’t being given the maximum amount importance”, Mukherjee said in dialogue with India.com.
Contrary to Mukherjee, AK Shukla, who was the top of the Centre for Semiology and Earthquake Risk Evaluation Centre of the India Meteorology Department had stated that there’s no technology to predict earthquakes. “The recent quakes are a warning. we’d like to possess a mitigation plan like having structures which will withstand tremors. Delhi also feels tremors whenever quakes occur within the Himalayas”, he added.
Last year, when the capital was hit by multiple earthquakes, IIT Guwahati Director TG Sitharam had said the closest point from the most Boundary Thrust (MBT) to Delhi is at around 200 kilometres. But there’s an opportunity of a much bigger earthquake of magnitude seven. Nothing are often ruled out. nobody can say when which will happen, said Sitharam, who was a part of the team that reviewed the NCS’ efforts to conduct seismic microzonation of Delhi.
