Following a magnitude 7.4 earthquake in western Colombia that has killed at least 281 people, injured more than 3,900, and left 379 missing, the disaster has revived urgent questions about whether scientists can predict seismic events. According to seismologists and official agencies, the short answer is no: neither the U.S. Geological Survey nor any other scientific body has ever accurately predicted the exact date, time, location, and magnitude of a major earthquake.
Why Short-Term Earthquake Prediction Remains Elusive
Earthquakes strike without warning because the Earth’s crust is divided into massive tectonic plates that constantly shift over hot, moving rock. According to experts, these plates usually remain locked, accumulating immense stress until something deep underground snaps. The sudden release of pressure sends energy surging through surrounding rock along fractured lines called faults. While seismologists understand this underlying physical mechanism well, predicting the exact timing and location of a fault failure remains impossible with current technology, according to the U.S. Geological Survey.
Suzan van der Lee, a professor of earth and planetary sciences at Northwestern University, notes that while researchers keep searching for useful warning indicators, none have yet proven dependable enough for practical forecasting. “We will never give up trying,” Van der Lee told reporters, “but so far, there is nothing promising that is reliable.” Similarly, Tim Wright of the UK-based Centre for Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET) noted that, “We aren’t anywhere near a short-term forecast.”
Global Seismic Activity and the Colombia Oddball Quake
Colombia sits in a complex seismic region where several tectonic plates interact. Van der Lee noted that the recent magnitude 7.4 event appears to be an “oddball” compared with classic shallow subduction-zone earthquakes associated with the world’s largest disasters. Because the Colombian tremor originated approximately 110 kilometers deep, the shifting fault line failed to break the surface or shift the ocean floor sufficiently to provoke a tsunami. Nevertheless, the tremor possessed enough energy to broadcast intense seismic waves across a wide region, generating extensive shaking and destruction above and surrounding the subterranean hypocenter.
This event follows other recent major tremors globally, including a magnitude 5.7 earthquake that struck Bangladesh on Friday (21 November), killing at least 10 people and injuring more than 600, according to the Bangladesh Meteorological Department. Other notable disasters this year include more than 1,400 people killed in Afghanistan in August, following the devastating earthquakes in Turkey and Syria in 2023, as reported by international news outlets.
Debunking Viral Fault-Loading Myths
Experts remain deeply skeptical of viral claims that one major earthquake instantly loads a distant fault enough to make another massive quake imminent elsewhere. Pointing to fault systems like the San Andreas, Van der Lee explains that California continues to face a significant threat of major earthquakes driven by the steady, ongoing friction between the Pacific and North American plates. However, she emphasized that the recent Colombia earthquake did not suddenly load the San Andreas Fault thousands of miles away.
In the San Francisco Bay Area, a magnitude 3.8 earthquake struck near San Leandro on Thursday, followed by smaller aftershocks with no immediate damage reported by the U.S. Geological Survey. Experts confirmed that this shaking was entirely normal for the region and did not indicate that a larger, catastrophic earthquake was imminent.
Did you know? The USGS estimates that roughly 20,000 earthquakes are detected around the world each year—averaging about 55 per day. Long-term records show about 16 major earthquakes annually, consisting of roughly 15 in the magnitude 7 range and one magnitude 8 or greater.
How Scientists Estimate Hazard and Prepare Communities
While precise prediction is out of reach, scientists use historical records, instrumental data gathered over the past century, and geological studies of prehistoric faults to calculate long-term probabilities. According to Geoscience Australia, researchers often dig trenches across known faults to examine soil profiles, determining the age and extent of past movements to build a history spanning thousands of years. This long-term view helps governments and civil engineers assess regional hazards and establish building codes.
Practical preparation remains the primary defense against seismic disasters. Experts advocate for stronger buildings, comprehensive emergency plans, dense seismic monitoring networks, and rapid public alerts utilizing earthquake early-warning systems. “It is very important that we keep monitoring earthquakes with seismic stations, that we keep recording them and sharing the data internationally,” Van der Lee said, “so that we can learn a lot more from possible bigger quakes that could occur by studying the smaller ones that occur in the same regions.”
Frequently Asked Questions
Can scientists predict when and where an earthquake will happen?
No. According to the U.S. Geological Survey and academic seismologists, no scientist has ever successfully predicted the exact date, time, location, and magnitude of a major earthquake.
Why do earthquakes seem to happen more frequently lately?
Global earthquake activity naturally fluctuates within normal statistical variations, according to the USGS. Improved modern monitoring instruments and instant global communications simply make us more aware of seismic events worldwide.
Did the Colombia earthquake trigger seismic activity in California?
No. Experts clarify that a major earthquake in South America does not instantly load distant faults thousands of miles away, such as the San Andreas Fault.
What is the best way to stay safe from earthquakes?
Experts emphasize preparation over prediction, which includes constructing earthquake-resilient buildings, developing family emergency plans, and utilizing regional early-warning alert systems.
