Large tremors lasting for a number of seconds had been felt in Delhi and different components of North India as a powerful 6.6-magnitude earthquake struck Afghanistan on Tuesday evening, the US Geological Survey (USGS) mentioned.
In keeping with the US Geological Survey (USGS), the earthquake was deep, with its origin 187.6 km beneath the earth’s floor. Notably, deep earthquakes are typically felt over giant distances, which is why tremors had been skilled in a number of areas of North India together with Punjab, Haryana, Ghaziabad, Delhi-NCR, Rajasthan’s Jaipur, and Jammu and Kashmir.
Reviews by the US Geological Survey (USGS) mentioned, “The earthquake’s epicentre was near Jurm in northeastern Afghanistan, about 300 km north of Kabul and never removed from Afghanistan’s borders with Tajikistan.”
Since they’ve extra power once they emerge on the floor, shallow earthquakes are usually extra devastating. Deeper earthquakes have misplaced quite a lot of their power by the point they attain the floor. Though they lose power whereas travelling additional distances, deeper earthquakes produce much less injury as a result of the seismic waves journey farther and move radially upward to the floor.
The Indian plate’s tectonics
The Indian Plate, additionally known as the India Plate, is a small tectonic plate that crosses the equator within the Jap Hemisphere. India, which initially belonged to the traditional continent Gondwana, break up other than the remainder of it (Gondwana) 100 million years in the past and began to float to the North. The vast majority of South Asia, or the Indian subcontinent, is roofed by the Indian Plate, as is a section of the basin of the Indian Ocean, which incorporates components of South China and western Indonesia, in addition to Ladakh, Kohistan, and Balochistan.
Motion of Indian Tectonic plate
The Indian tectonic plate consists of Peninsular India and the Australian continental parts. The Himalayan subduction zone creates the northern plate boundary within the type of continent-continent convergence. The Indian plate extends by means of the Arakan mountains, additionally known as Rakhine Yoma, within the east in Myanmar. The Western margin follows the Kirthar Mountain of Pakistan which extends alongside the Makrana coast (Pakistan and Iranian coasts) and joins the spreading web site from the Pink Sea rift (Pink Sea rift is fashioned because of the divergence of Somali plate and Arabian plate) south-eastward alongside the Chagos Archipelago (Fashioned as a result of hotspot volcanism).
The boundary between India and the Antarctic plate can also be marked by an oceanic ridge (divergent boundary) working in roughly W-E route and merging into the spreading web site, somewhat south of New Zealand.
About 40-50 million years in the past, India collided with Asia inflicting uplift of the Himalayas because the Indian plate and the Eurasian plate had been near the equator again then. Notably, the northward motion of the Indian tectonic plate pushing slowly towards the Asiatic plate is visibly evident by the frequent earthquakes within the area.
What results in an earthquake?
Because the earth’s crust is made up of huge tectonic plates which float on high of the Earth’s molten mantle, these plates steadily transfer slowly and continuously, both away from one another or in the direction of one another or previous one another, in a course of known as plate tectonics.
When two tectonic plates transfer towards one another, they’re caught, thus build up stress as they proceed to push towards one another. Ultimately, this stress causes the rocks to deform and finally break which in consequence releases power within the type of seismic waves. These waves journey by means of the Earth’s crust and trigger the bottom to shake, leading to an earthquake.
