On the morning of Saturday, April 12, 2025, the United States Geological Survey (USGS) reported a 6.2-magnitude earthquake that struck off the southeastern coast of Papua New Guinea’s New Island region. The quake’s epicentre was recorded approximately 115 kilometres southeast of the coastal town of Kokopo, located on the island of New Britain. Occurring at a depth of 72 kilometres (about 44 miles), this moderate-to-strong earthquake is the latest reminder of the constant tectonic activity occurring beneath the Earth’s surface in one of the world’s most seismically active regions. Although the earthquake’s magnitude was significant, early reports indicate minimal local impact. According to Emonck Abelis, a receptionist at the Kokopo Beach Bungalow Resort, the tremor lasted roughly one minute but caused no visible damage in the vicinity. “There was some shaking, but everything seems okay,” she said, expressing relief that the quake had not resulted in any harm.
Papua New Guinea lies at the intersection of several major tectonic plates, including the Pacific Plate, the Australian Plate, and numerous smaller microplates. This intricate and dynamic geological setting places the country directly along the Pacific Ring of Fire—an extensive horseshoe-shaped belt of seismic activity that stretches through Southeast Asia, the Pacific Islands, the western coasts of North and South America, and beyond. This region is notorious for its frequent earthquakes and volcanic eruptions, with about 90% of the world’s earthquakes occurring within the Ring of Fire. The plates in this region are in constant motion, grinding against one another, pulling apart, or colliding at various fault lines. When stress builds up from these movements and is suddenly released, it results in an earthquake. Due to its position within this tectonic hotspot, Papua New Guinea is no stranger to seismic activity. The frequency and potential destructiveness of such events require continuous monitoring, robust preparedness strategies, and infrastructure capable of withstanding tremors.
