Summary
A moderate earthquake with a magnitude of 4.5 struck the Bay of Bengal early Sunday morning, off the coast of Andhra Pradesh. The National Center for Seismology (NCS) reported the quake occurred at 5:05 AM IST at a shallow depth of 10 kilometers. The epicenter was located about 200 kilometers east of Kakinada, a major port city in the state. No immediate reports of damage or casualties have been received, and authorities are monitoring the situation.
Main Impact
The earthquake, while moderate in strength, was felt in several coastal areas of Andhra Pradesh, including Kakinada, Visakhapatnam, and Rajahmundry. Residents reported mild shaking and rattling of windows, but no structural damage or injuries have been confirmed. The shallow depth of the quake, at just 10 kilometers, meant the shaking was more noticeable near the epicenter, though the offshore location reduced the risk of serious impact on land. The NCS has classified the event as "Reviewed," meaning the data has been verified and finalized.
Key Details
What Happened
The earthquake struck at 05:05:46 IST on Sunday, July 12, 2026. The epicenter was located at 16.805° N latitude and 84.381° E longitude, which is in the Bay of Bengal, roughly 200 kilometers east of Kakinada. The quake had a magnitude of 4.5 on the Richter scale, which is considered moderate and typically causes only minor shaking. The depth of 10 kilometers is relatively shallow, meaning the energy released was closer to the surface, making it more perceptible to people on land.
Important Numbers and Facts
Key data from the NCS includes: magnitude 4.5, depth 10 kilometers, and epicenter coordinates 16.805° N, 84.381° E. The quake occurred at 05:05:46 IST. The event has been marked as "Reviewed," indicating the NCS has confirmed the readings. The Bay of Bengal is a seismically active region, but quakes of this size are not uncommon and rarely cause significant damage. The nearest major city is Kakinada, about 200 kilometers west of the epicenter.
Background and Context
The Bay of Bengal sits on the boundary of the Indian tectonic plate and the Burma microplate. This area experiences frequent small to moderate earthquakes due to the movement of these plates. While most are too small to feel, quakes of magnitude 4.0 to 5.0 occur several times a year. The shallow depth of this quake made it more noticeable, but the offshore location meant the shaking was weaker by the time it reached land. The NCS monitors seismic activity across India and provides real-time data to help assess risks.
Public or Industry Reaction
Residents in coastal Andhra Pradesh reported feeling the quake, with many taking to social media to describe the experience. "I felt a sudden jolt while sleeping," said a resident of Kakinada. "It lasted only a few seconds, but it was enough to wake me up." Local authorities have not issued any warnings or evacuation orders, as the quake was too small to pose a tsunami risk. The Indian Meteorological Department (IMD) confirmed there is no tsunami threat to the Indian coast. Shipping and fishing activities in the Bay of Bengal were not disrupted, according to port officials.
What This Means Going Forward
This earthquake serves as a reminder of the seismic activity in the Bay of Bengal region. While a magnitude 4.5 quake is not dangerous, it highlights the need for continued monitoring and public awareness. The NCS will likely review the data to improve future predictions and early warning systems. For residents, the event is a prompt to review earthquake safety measures, such as securing heavy furniture and knowing safe spots during shaking. No aftershocks have been reported so far, but the NCS will continue to track any subsequent activity.
Final Take
The moderate quake off the Andhra Pradesh coast caused no harm but was a clear signal of the region's ongoing tectonic activity. With no damage or injuries, the event is a routine occurrence in a seismically active area. It underscores the importance of preparedness and reliable monitoring by agencies like the NCS to keep communities safe.
Frequently Asked Questions
Was this earthquake dangerous?
No. A magnitude 4.5 earthquake is considered moderate and typically causes only minor shaking. Because it occurred offshore, the risk of damage was very low. No injuries or structural damage have been reported.
Could this quake cause a tsunami?
No. Earthquakes of magnitude 4.5 are too small to generate a tsunami. The Indian Meteorological Department confirmed there is no tsunami threat to the Indian coast.
How common are earthquakes in the Bay of Bengal?
Small to moderate earthquakes are common in the Bay of Bengal due to tectonic plate movements. Quakes of magnitude 4.0 to 5.0 occur several times a year, but most are not felt on land. This event was notable because of its shallow depth and proximity to the coast.
