The quiet of the night was broken in Telangana's Bhadradri Kothagudem district when the ground suddenly began to shake. Tremors were felt across the area at around 2:26 am on the intervening night of Saturday and Sunday. The quake measured 3.8 magnitude on the Richter scale. Because it struck in the dead of night, most residents were fast asleep, and many did not even realise the earth had moved.
Where And When It Happened
According to the National Center for Seismology, the tremors were recorded in Bhadradri Kothagudem district, with the epicentre lying just 10 kilometres beneath the surface. Locals felt only mild shaking after midnight, but the vibrations were too weak to cause any widespread effect. Reassuringly, there have been no reports so far of any damage to life or property.
How Dangerous Is A Quake Of This Size
A 3.8-magnitude earthquake is generally counted within the safe range. Such tremors are usually noticeable to people nearby, but the chances of buildings collapsing or major destruction are next to none. This event too caused no significant harm. Experts note, however, that had the magnitude crossed 6, the situation could have turned far more serious.
Understanding The Richter Scale
The strength of an earthquake is measured on the Richter scale or the more modern moment magnitude scale. What is striking is that this is a logarithmic scale — with every single point increase, the strength of the shaking jumps tenfold, while the energy released rises by roughly 31 to 32 times. That is why even a small bump in the number translates into a world of difference in impact.
Here is how tremors of different magnitudes typically behave:
- Below 3.0: Very faint, mostly not felt at all.
- 3.0–3.9: Minor — often felt, but damage is very little or negligible.
- 4.0–4.9: Light to moderate — cracks may appear in some weaker structures.
- 5.0–5.9: Moderate — minor damage to sturdy buildings and considerable damage to weak ones.
- 6.0–6.9: Strong — destruction over a large area, with effects reaching hundreds of kilometres.
- 7.0–7.9: Major quake — severe damage, potentially thousands of deaths.
- 8.0 or above: Great quake — devastation, millions affected and the threat of a tsunami.
Why Do Earthquakes Happen?
The Earth's outer crust is not a single solid sheet but is divided into several tectonic plates. These plates keep drifting at a pace of a few centimetres every year. When they collide, grind against one another or pull apart, stress steadily builds up between them. A point eventually comes when this pressure becomes too much to hold, and the plates slip suddenly. The energy released by that slip spreads out as seismic waves, which is exactly what we feel as an earthquake.
India sits largely on the Indian Plate, which is continuously pushing against the Eurasian Plate. It is this very collision that is lifting up the Himalayas. Regions like Telangana usually see few earthquakes, but small tremors like this one are recorded from time to time.
