An earthquake measuring 6.0 in magnitude struck the South Pacific Ocean on Wednesday, according to the National Center for Seismology (NCS). The tremor was recorded on 11 February 2026 at 02:14:53 IST. The earthquake occurred at a deep depth of 515 kilometers below the Earth’s surface. Its location was marked at latitude 21.15 South and longitude 178.28 West in the South Pacific Ocean region.
The NCS shared the details in a post on X. The agency confirmed the magnitude, time, depth, and exact coordinates of the earthquake. Because the earthquake occurred deep under the ocean, there were no immediate reports of major damage. Deep earthquakes often cause less surface impact compared to shallow ones, but they are still closely monitored by scientists.
The South Pacific Ocean lies along one of the most active earthquake zones in the world. This region is part of the circum-Pacific seismic belt, also known as the Pacific Ring of Fire. According to the United States Geological Survey (USGS), around 81 percent of the world’s largest earthquakes happen in this belt. Because of frequent volcanic eruptions and earthquakes, the region is called the “Ring of Fire.”
The Ring of Fire stretches about 40,000 kilometers (25,000 miles) around the Pacific Ocean. It can be up to 500 kilometers (310 miles) wide in some areas. This belt covers the coasts of several countries, including parts of South America, North America, and Asia. It is one of the most seismically active regions on Earth.
Earthquakes in this zone happen because of tectonic plate movements. The Earth’s surface is divided into large plates that constantly move. In the Ring of Fire region, many of these plates are oceanic plates that sink under other plates. This process is called subduction. When these plates move, slip, or break, energy is released in the form of earthquakes.
Some of the strongest earthquakes in history have occurred in the Pacific Ring of Fire. These include the 1960 Chile earthquake, also known as the Valdivia earthquake, which measured 9.5 in magnitude and is the largest ever recorded. Another major quake was the 1964 Alaska earthquake, which had a magnitude of 9.2. Both caused massive destruction and loss of life.
Experts estimate that around 500,000 earthquakes are detected worldwide each year. Out of these, about 100,000 can be felt by people. Around 100 earthquakes each year cause serious damage. However, most earthquakes happen under the ocean or in remote areas and do not cause harm.
The current shape of the Pacific Ring of Fire developed over millions of years. Scientists say that subduction zones first formed in South America, North America, and Asia around 115 million years ago. Later, around 70 million years ago, new subduction zones developed near Indonesia and New Guinea. The New Zealand subduction zone formed about 35 million years ago. Over time, the movement of tectonic plates shaped the region into what we see today.
Authorities continue to monitor seismic activity in the South Pacific region. While this 6.0 magnitude earthquake occurred deep below the ocean floor, experts keep tracking such events to understand patterns and reduce future risks. Monitoring helps governments and disaster management agencies stay prepared for any possible impact.
The latest earthquake once again highlights the active nature of the Pacific Ring of Fire. Even though no immediate damage has been reported, scientists remain alert as the region continues to experience frequent seismic activity.
