Why Earthquakes Are Striking Worldwide Simultaneously
News Desk
Islamabad: A series of powerful earthquakes in different parts of the world over the past few days has raised concerns among people, prompting many to ask whether these seismic events are somehow connected.
The first major earthquakes, measuring 7.2 and 7.5 in magnitude, struck off the coast of Venezuela, causing widespread devastation. According to initial reports, more than 1,400 people have died, while over 50,000 remain missing.
Shortly afterward, a powerful 6.9-magnitude earthquake struck the Sea of Japan. Around the same time, a 5.6-magnitude earthquake was recorded in the US state of California, described as the strongest quake to hit the region since 1940.
Meanwhile, earthquake tremors were also felt in Pakistan’s Balochistan province, with the epicenter located in neighboring Afghanistan.
The occurrence of several significant earthquakes within a short period has sparked fears that they may be linked. However, geologists and seismologists say there is no scientific evidence to support such a connection.
Professor Peter Stafford of Imperial College London explained that earthquakes occur independently due to local geological conditions and tectonic activity.
According to Professor Stafford, California experiences two to three earthquakes of similar magnitude every year, while Japan also records major earthquakes on a fairly regular basis. Venezuela, however, experiences earthquakes of such intensity much less frequently, often once every 50 to 100 years.
He noted that if these earthquakes were connected, similar seismic activity would likely have occurred along the tectonic boundaries and fault lines between the affected regions. Since that has not happened, he described the timing of these earthquakes as a statistical coincidence rather than a linked global event.
Scientists have also rejected claims that the world is experiencing an increase in major earthquakes.
According to American seismologists, earthquake activity naturally fluctuates from year to year. Some years witness more powerful earthquakes, while others experience fewer.
Experts also point out that modern technology has significantly improved earthquake detection. The growing number of advanced seismic monitoring stations around the world now records many small earthquakes that would have gone undetected in the past.
According to the US Geological Survey (USGS), approximately 20,000 earthquakes of varying magnitudes are recorded worldwide each year, an average of about 55 earthquakes every day. Most are so minor that they pass unnoticed by the public.
Historical data from the past century shows that the world experiences an average of 16 major earthquakes with magnitudes of 7.0 or higher each year. In some years, the number is significantly higher, such as 2010, when 23 major earthquakes were recorded. In contrast, only six earthquakes of magnitude 7.0 or above occurred in 1989.
The strongest earthquake ever recorded struck Chile in 1960, registering a magnitude of 9.5 and claiming more than 1,600 lives.
In 2004, a magnitude 9.1 earthquake off the coast of Indonesia triggered a devastating tsunami that killed more than 280,000 people across the Indian Ocean region.
More recently, in 2025, a powerful magnitude 8.8 earthquake struck Russia’s Kamchatka Peninsula.
Experts stress that earthquakes are a natural consequence of the Earth’s tectonic processes and urge the public to rely on scientific evidence rather than speculation or rumors when interpreting seismic events.
