Scientists Say Recent Powerful Earthquakes Around the World Are Coincidental, Not Connected
A series of powerful earthquakes reported in different parts of the world over the past few days has raised concerns about whether the seismic events are connected. However, geologists and seismologists say there is no scientific evidence linking them.
The recent earthquakes include a powerful offshore earthquake near Venezuela, a magnitude 6.9 quake off the coast of Japan, a magnitude 5.6 earthquake in California, and tremors felt in Pakistan’s Balochistan province originating from Afghanistan.
According to experts, these earthquakes occurred on different tectonic fault systems and were triggered by separate geological processes. Professor Peter Stafford of Imperial College London explained that such events are common in various regions of the world and do not indicate a global chain reaction.
He noted that California typically experiences two to three earthquakes of similar magnitude each year, while Japan also regularly records strong earthquakes due to its location along active tectonic plate boundaries. Large earthquakes in Venezuela are less frequent but are a known part of the region’s seismic history.
Professor Stafford added that if the earthquakes were truly connected, seismic activity would likely have been observed along the fault systems between these regions, which was not the case.
Scientists also rejected claims that the number of major earthquakes is increasing globally. According to U.S. geological experts, annual fluctuations in earthquake activity are normal, and the apparent rise in recorded earthquakes is mainly due to improvements in modern monitoring technology, which can detect even very small tremors.
The U.S. Geological Survey (USGS) estimates that approximately 20,000 earthquakes of varying magnitudes are recorded worldwide each year—an average of about 55 per day. Most are too small to be felt by people.
Historical records show that the world experiences an average of around 16 major earthquakes with a magnitude of 7.0 or higher each year. Some years see more, such as 2010, while others record fewer.
The strongest earthquake ever recorded occurred in Chile in 1960, measuring magnitude 9.5. Another devastating event struck off the coast of Indonesia in 2004, when a magnitude 9.1 earthquake triggered a catastrophic tsunami that claimed more than 280,000 lives.
Experts emphasize that earthquakes are a natural part of Earth’s geological processes and advise the public to rely on scientific information rather than rumors or speculation when multiple seismic events occur close together in time.
