Telangana: Residents of the Mulugu area in Telangana experienced an unexpected awakening on the morning of December 4, 2024, as a 5.3 magnitude earthquake jolted the region at approximately 7:27 a.m. The quake struck at a depth of 40 kilometers, according to the National Center for Seismology (NCS). This seismic event is notable as it represents the second-largest earthquake in Telangana in the past 55 years, with the epicenter located near the Godavari riverbed, about 200 kilometers from Hyderabad, the state capital.
The tremors were felt widely across several districts in Telangana and Andhra Pradesh, extending even to neighboring states such as Chhattisgarh and Maharashtra. Reports indicated that residents in areas like Warangal experienced brief but noticeable shaking, with ceiling fans swinging and items falling from shelves. 

Understanding the Uncommon Nature of Earthquakes in Telangana

Retired scientist Purnachandra Rao from the National Geophysical Research Institute (NGRI) highlighted that significant earthquakes, particularly those exceeding a magnitude of five, are rare occurrences in both Telangana and Andhra Pradesh. He recounted a previous incident in 1969, when a 5.7 magnitude earthquake was recorded in Bhadrachalam. "We have got to know that people felt the tremors lightly," Dr. Prakash Kumar, Director of CSIR-NGRI, explained. He emphasized that "Hyderabad is not an earthquake-prone area... it is not severe."

A significant portion of India's landmass—approximately 59%—is susceptible to earthquakes of varying intensities. The country is classified into four seismic zones: Zone II (least active) to Zone V (most active). Notably, Telangana falls under Zone II, indicating a lower risk for severe seismic activity. The Geological

Significance of the Godavari Fault Zone

Following the earthquake attributed to the Godavari fault zone, experts predict possible aftershocks over the coming days but reassure that there is no immediate cause for alarm. The fault zone represents a critical geological boundary where tectonic plates shift, leading to seismic events. Purnachandra Rao noted that while aftershocks are possible, residents should remain calm. 

Residents Share Their Experiences: A Morning of Uncertainty

Several residents reported their experiences during the quake. Many described feeling a brief but unsettling tremor around 7:30 a.m., with some noting that ceiling fans began to sway and objects fell from shelves. The unexpected nature of this event left many feeling anxious and uncertain about safety measures in place. 

 

 

Urgent Call for Enhanced Building Safety Standards

D. Srinagesh, another retired chief scientist at NGRI, remarked that this earthquake serves as a crucial reminder for both Telangana and Andhra Pradesh regarding building safety standards. He urged local municipalities to ensure that structures are designed to withstand potential earthquakes specific to their seismic zones. "Disaster management authorities must take necessary steps to ensure that structures meet design standards," he stated.

Srinagesh further stressed the importance of earthquake preparedness to mitigate loss of life and property damage. Since 1982, geophysical hazards such as earthquakes and landslides have caused between 30,000 and 40,000 fatalities in India alone. He cited the devastating impact of the 1993 Killari earthquake, which resulted in significant casualties due to inadequate building designs compared to a similar-magnitude quake in San Francisco that claimed only 24 lives thanks to robust earthquake-resistant infrastructures. 

Looking Ahead: Preparedness and Awareness Initiatives

As residents recover from this startling event, experts continue to monitor seismic activity in the region while advocating for enhanced safety measures and public awareness regarding earthquake preparedness. Local authorities are encouraged to conduct drills and educational campaigns aimed at informing citizens about how to respond during seismic events. In conclusion, while this recent earthquake has raised concerns among residents and experts alike, it also serves as an important opportunity for communities in Telangana and Andhra Pradesh to reassess their preparedness strategies and ensure that infrastructure is resilient against future seismic threats.
