A series of major earthquakes along the Pacific Ocean's 'Ring of Fire' has raised concerns among geophysicists about the potential for a significant seismic event on the US West Coast. Geophysicist Stefan Burns stated in comments to the Daily Mail that recent tectonic activity, particularly along the Pacific Plate, indicates a shifting pattern that could precede a historic disaster.
Burns suggested that the same megaquakes that have impacted Asia in recent years may be moving towards the eastern side of the Pacific Plate. He warned that California, Oregon, Washington, and Alaska could face an increased risk of a massive earthquake, with a devastating rupture potentially occurring within the next four years. "We are in this time period where we can expect more earthquake activity in California because there's like a 35-year rhythm there," Burns explained, referencing cycles observed in the 1980s and 1990s. He pointed to recent earthquakes in California, including Napa in 2014 (magnitude 6.0) and Ridgecrest in 2019 (magnitude 7.1), and a reported Ukiah-Willits event in 2026 (magnitude 5.6), suggesting that the period up to 2030 could see a significant earthquake.
Recent seismic activity includes a magnitude 5.2 earthquake near the US-Canada border in Alaska on July 16 and a magnitude 7.3 quake off the coast of Chiapas, Mexico, on July 17. These events follow more than a dozen earthquakes stronger than magnitude 7 recorded on the western side of the Ring of Fire in Russia, Japan, the Philippines, and Indonesia over the past year. Burns noted the precedent for such activity to shift and potentially activate regions along the eastern side of the plate.
The Ring of Fire, a 25,000-mile arc encircling the Pacific Ocean, is known for its high concentration of active volcanoes and frequent earthquakes. Burns cited an August 2025 magnitude 8.8 megaquake in Kamchatka, Russia, as a trigger for a seismic chain reaction across the Ring of Fire. This event, he posited, released significant built-up stress, leading to numerous magnitude 7 earthquakes and many smaller ones on the western side of the Pacific Plate. According to Burns, the Pacific Plate functions as a large, relatively stable segment of the Earth's crust that requires balance. He believes that the extensive movement on the western side necessitates further activity on the eastern side, including the US West Coast and South America, to release stress and maintain equilibrium.
Burns highlighted specific warning signs in California, such as a recent earthquake near the junction of the Garlock and San Andreas Faults. He described this as concerning because the Garlock Fault serves as a crucial stress transfer point in Southern California, potentially indicating that the region is accumulating stress for a major rupture along the 800-mile San Andreas fault system.
Several factors may be contributing to the increased seismic activity. Burns mentioned the Chandler wobble, Earth's natural 433-day rotational wobble, which diminished in the 2010s and is now returning with a phase shift. A 2025 study in the Journal of Geodesy confirmed this shift. Burns indicated that historical earthquake data suggests a correlation between the Chandler wobble cycle and increased earthquake likelihood, with the wobble potentially adding incremental stress to faults.
Additionally, changes in Earth's magnetic pole movement and solar activity are theorized by Burns to influence tectonic plate behavior. He suggested that periods of lower solar activity can lead to earthquake clustering due to effects on internal electric currents within the planet. "In general, the sun is the main energetic agent loading our Earth with energy," Burns stated, adding that high-magnitude earthquakes often coincide with specific space weather influences.
New research suggests that the San Andreas Fault and the Cascadia Subduction Zone off the coast of Oregon could potentially rupture simultaneously, creating an even larger disaster. While the exact timing remains uncertain, Burns indicated that patterns observed along the San Andreas Fault are developing more slowly than those preceding major earthquakes in Asia, suggesting the US may have some additional time before a significant event occurs.
