Mild Earthquake Shakes Rajasthan: What You Need to Know

On Saturday morning, a mild earthquake measuring 3.5 on the Richter scale struck near Sikar district in Rajasthan, causing brief tremors felt by residents. The quake, occurring at a shallow depth of 5 km, did not result in any reported damage or casualties. Experts note that while Sikar is not in the highest risk zone, its proximity to Jaipur makes it susceptible to occasional tremors. Increased human activity in the Aravalli Range may also contribute to seismic activity. Read on for more insights into the earthquake and its implications.
 

Earthquake Tremors Felt in Rajasthan

Early Saturday morning, residents in parts of Rajasthan experienced mild tremors following a low-intensity earthquake that registered 3.5 on the Richter scale near Sikar district, as reported by officials.


The National Center for Seismology indicated that the quake struck around 6:30 a.m., with its epicenter located roughly 69 kilometers northwest of Jaipur at a shallow depth of about 5 kilometers beneath the Earth's surface.


Tremors were felt across various areas in Sikar district, particularly in Khatushyamji, Palsana, Dhingpur, and surrounding regions. Witnesses noted that the shaking lasted for approximately one to two seconds.


In Palsana, residents reported that doors and windows rattled momentarily, and some claimed to have heard strange noises during the tremor. Fortunately, authorities confirmed that the earthquake was minor, with no casualties or property damage reported.


Seismologists explain that shallow earthquakes, even those of lower magnitudes, can be felt more intensely due to the shorter distance seismic waves travel to reach the surface.


About three months prior, the Bureau of Indian Standards published an updated seismic risk map for India.


This revised map classifies cities like Jaipur, Alwar, and Bhiwadi as being in higher earthquake risk zones, indicating a potential for quakes in the 5 to 6 magnitude range, which could lead to structural damage, especially in older or poorly built structures.


While Sikar is not classified in the highest risk zone, experts suggest that its closeness to Jaipur means it can occasionally experience mild tremors.


Geologists also highlight that increased human activities in the Aravalli Range, such as extensive construction, mining, and tunneling, may weaken underground rock formations and disturb existing fault lines, potentially raising the chances of minor seismic events in the region.
