Delhi Earthquake: What are aftershocks and how dangerous are they? PM Modi advised to stay alert of these
4.0 magnitude earthquake shakes Delhi-NCR, people rush outdoors – understanding the impact of aftershocks
The earthquake tremors felt around Delhi and the National Capital Region (NCR) on Monday morning have created panic among the people. The intensity of the earthquake that occurred at around 5.36 am was measured at 4.0 on the Richter scale. However, the impact of the tremors recorded was quite strong. This earthquake created a stir in Delhi NCR. People were seen coming out of their homes in parks.
The National Center for Seismology said that the intensity of the earthquake was measured 4.0 on the Richter scale and its depth was 5 kilometers and the epicenter of this earthquake was Delhi, so these tremors felt more powerful. After this, PM Modi himself came on social media and warned people about 'Aftershocks' after the earthquake. In such a situation, let us know what is the 'aftershocks'.
Prime Minister Narendra Modi appealed to the residents of Delhi NCR to remain calm after the earthquake and urged them to follow the safety protocol for protection. PM Modi wrote on his official X handle, "Tremors were felt in Delhi and nearby areas. Urging everyone to stay calm and follow safety precautions, staying alert for possible aftershocks. Authorities are keeping a close watch on the situation."
What are 'aftershocks'?
According to scientists, aftershocks are smaller earthquakes that occur after a major earthquake. Aftershocks occur as a result of sudden changes in the tension within and between rocks caused by major earthquakes. Aftershocks typically occur near the epicenter of the original quake or along the fault line that hosted the main shock.
How harmful is it?
Although the intensity of aftershocks is usually less than the main earthquake, at times they can be so powerful that they can cause massive destruction by demolishing damaged buildings and houses. Aftershocks can be another big challenge for residents of earthquake-prone areas.
For example, the magnitude 7.1 earthquake in Luanxian, China, on July 28, 1976, was followed by a magnitude 7.5 aftershock in the nearby city of Tangshan within a few hours. This aftershock killed thousands of people and destroyed many buildings.
