According to the National Center for Seismology (NCS), an earthquake of 6.0 magnitude was recorded in the Coral Sea early on Sunday. This earthquake was felt at 4:58 am (IST) on 26 October 2025. The epicenter of the earthquake was located about 632 kilometers north-northwest (NNW) of Port Vila, the capital of Vanuatu.
The depth of the earthquake was only 10 kilometers, so the tremors were quite strong. However, no information about any loss of life or damage has been received so far. The local administration is taking precautionary measures and the area is being monitored.
Why are upper earthquakes considered more dangerous?
According to geology experts, when earthquake waves originate very close to the surface, they cause more vibrations in a shorter distance. Due to this, the intensity of tremors on the ground increases, buildings and structures shake rapidly and the possibility of loss of life and property increases. This time the matter of relief was that the earthquake occurred under the sea, due to which its impact on the populated areas was limited.
Pacific Ocean Seismic Hotspot
The region of the Coral Sea, Vanuatu, and the Solomon Islands is among the Earth’s most active seismic belts. This area is located between the Pacific Plate and the Indo-Australian Plate. According to scientists, there exists a subduction zone here, where the Indo-Australian plate is sliding beneath the Pacific plate. This process creates continuous seismic stress, which periodically comes out in the form of major earthquakes. According to experts, the Australian continent is moving towards the north-east at the rate of about 6 centimeters per year, while in some places this speed reaches 13 centimeters per year. This is why Vanuatu, Fiji, Solomon Islands and Papua New Guinea are considered the most active parts of the global seismic belt.
The tragedy of 2024 is still remembered
The 7.3 magnitude earthquake that struck Vanuatu in December 2024 caused massive devastation in the region. According to the World Health Organization (WHO) report, 14 people died in that accident. More than 2,000 people were left homeless and many hospitals and schools were destroyed. Since then, Vanuatu and Solomon Islands have further strengthened their Disaster Preparedness System, so that they can better face future disasters.
There is no danger of tsunami but vigilance continues
According to the International Seismological Center (ISC), this shock did occur in the sea, but its intensity and depth were not enough to cause a tsunami. Nevertheless, Vanuatu and Solomon Islands disaster management agencies (NDMOs) are monitoring possible aftershocks.
