Kuala Lumpur – A significant 7.1-magnitude earthquake struck off the coast of Malaysia’s Sabah state on Borneo island early Monday, February 23, 2026, according to reports from US seismologists. The quake, which occurred at 12:57 a.m. Local time, was centered approximately 100km northeast of Kota Kinabalu, the state capital, at a depth of 619.8km, as reported by the United States Geological Survey (USGS). Whereas the magnitude is substantial, the considerable depth of the quake has lessened concerns about widespread damage.
The USGS initially assessed the likelihood of casualties and significant damage as low, a determination supported by the fact that the earthquake originated at a great depth. The US Tsunami Warning Centre confirmed that no tsunami warning was issued, citing the depth as a key factor in preventing the generation of large waves. This earthquake follows a series of seismic events in the region, including a 4.1-magnitude quake in Segamat, Johor, Malaysia, on August 24, 2025, which was felt across several states, according to reporting at the time.
The Malaysian Meteorological Department stated it is continuing to monitor the situation closely, reporting a magnitude of 6.8 and confirming that tremors were felt along Sabah’s west coast, as well as in areas of Sarawak state and Peninsular Malaysia. The Sabah Fire and Rescue Department reported that as of early Monday, no incidents had been reported in connection with the earthquake. “All stations are patrolling and monitoring their areas to ensure public safety and keep the situation under control,” the department said in a statement relayed by the Malaysian news agency Bernama.
Tremors Reported in Singapore
While the earthquake’s epicenter was offshore, tremors were reportedly felt in several locations in Singapore, including Toa Payoh, Balestier, and Punggol. Residents took to social media to share their experiences. One Reddit user, dcburn, who lives in Singapore’s East Coast area, described it as “one of the strongest tremors” they had ever felt. Facebook user Soniakaur Soniasingh reported feeling a “bit (of a) shake” while watching a movie in Ang Mo Kio, initially attributing the sensation to a health issue. “I thought (in) my head my high blood pressure was up. Suddenly spinning, giddiness… Even my daughter (who) was on the way home from Bishan to Ang Mo Kio felt the shaking,” she posted on Facebook.
Singapore’s Meteorological Service confirmed the quake’s location approximately 1,500km from Singapore in an update at 1:13 a.m. On February 23, but reported no tremors were reported within Singapore and no tsunami advisory was issued. According to the National Library Board’s Singapore Infopedia, Singapore does not typically experience earthquakes due to its location outside of major earthquake zones, but low-level tremors are occasionally felt as a result of seismic activity in nearby Sumatra, Indonesia.
Geological Context and Risk Assessment
While Malaysia is not situated within the Pacific Ring of Fire, it does experience occasional tremors due to the presence of minor fault lines and geological features within its borders. Natural Resources and Environmental Sustainability Minister Arthur Joseph Kurup stated earlier in February that the country’s risk of experiencing earthquakes over the next 10 years is assessed to remain at a low to moderate level. He explained that Malaysia’s location on the Sunda Shelf contributes to a relatively stable geological setting. However, the Ministry of Natural Resources and Environmental Sustainability as well cautioned that this stability is not absolute, as the country remains affected by tectonic stress from the interaction of major plates in the region.
The depth of this particular earthquake – 619.8km as measured by the USGS – is a significant factor in mitigating potential damage. Deep-focus earthquakes, like this one, tend to dissipate energy before reaching the surface, reducing the intensity of shaking in populated areas. The USGS impact models indicated a “green” alert, signifying a low likelihood of severe damage or casualties.
As of this reporting, authorities in Malaysia and Singapore continue to monitor the situation. Further assessments will be crucial in determining if any unforeseen impacts have occurred. The focus remains on ensuring public safety and providing updates as more information becomes available.
