The Pacific Ocean is running a fever, and the whole planet is feeling it. Sea surface temperatures in the central-eastern Pacific have climbed more than 2 degrees Celsius above average, and forecasters at NOAA and the European Center for Medium-Range Weather Forecasts now say the world is watching a Super El Nino take shape in real time, potentially one of the strongest ever recorded.
At the same time, a wave of destructive earthquakes and record heat has fueled online speculation that El Nino is not just warming the planet; it is shaking it too. So what is actually true here? Let us separate the confirmed science from the speculation.
What Is a Super El Nino, and Is One Really Forming?
El Nino is the warm phase of a natural Pacific Ocean cycle called ENSO (El Niño-Southern Oscillation). It happens when trade winds weaken, and warm water that is normally pushed toward Asia sloshes back east toward South America. A “Super” or “very strong” El Nino requires sea surface temperature anomalies of 2.0C or higher in the Nino 3.4 monitoring region, a threshold only reached five times since modern record-keeping began.
As of mid-2026, that threshold has already been crossed. NOAA’s Climate Prediction Center has confirmed that El Nino conditions are established and intensifying, with weekly readings in the Nino 3.4 region climbing past +2.1 °C in July. Some forecast models put the odds of a full “Super” event by year-end as high as 80% for a strong event, with a meaningful chance it becomes one of the most intense on record.
Why Temperatures Are Already Climbing
This part of the story has strong scientific backing. A large El Nino releases enormous amounts of heat that had been stored in the deep ocean, dumping it into the atmosphere. Climate scientists describe this as a temporary boost on top of the planet’s existing warming trend, often adding another 0.2C to 0.3C to global average temperatures.
That matters because this El Nino is not developing in isolation. It is arriving on top of roughly 1.3C of human-caused warming since the pre-industrial era. Researchers have warned that the combination could push global temperatures to new record highs in 2026 and 2027, with some estimates suggesting temporary spikes approaching 1.7C above pre-industrial levels during peak El Nino months.
The effects are already visible: record-breaking heatwaves across North America and Europe this year, intensified wildfire seasons in the Mediterranean, and shifting rainfall patterns from South America to Southeast Asia.
Where the Extreme Weather Risk Is Concentrated
El Nino impacts various regions differently. Risk experts note that Australia, Central America, southwestern Africa, and sections of Southeast Asia are more prone to droughts and wildfires. In contrast, western South America, parts of Brazil, and the southwestern US are more susceptible to heavy rains and flash floods.
Typically, Atlantic hurricane activity declines while Pacific typhoon activity increases, a trend that NOAA has already incorporated into its 2026 hurricane forecast.
The Earthquake Question: What Does the Science Actually Say?
Here is where the story gets murkier, and where many viral claims are running well ahead of the evidence.
Mainstream seismology confirms that earthquakes are caused by tectonic plate movement, not ocean temperatures. The U.S. Geological Survey, the primary authority on seismic hazards, does not identify El Nino as a trigger for earthquakes. Instead, tectonic stress builds up over decades along fault lines, independent of surface ocean conditions in the Pacific.
However, this remains an open question in scientific research. Some studies have investigated whether the redistribution of large volumes of ocean water during El Nino could subtly influence crustal loading, potentially pushing already-stressed faults toward failure.
Additionally, some researchers have explored how changes in rainfall during El Nino might affect pore-water pressure in underground aquifers, possibly having a minor impact on seismic activity in certain regions.
But researchers who have studied this are clear about the limits of what they have found. Reviews of the evidence describe any statistical correlation between ENSO cycles and earthquake activity as weak, inconsistent across studies, and easily explained by chance or by how researchers define an “El Nino episode” in the first place.
The consensus among seismologists remains that tectonic forces overwhelmingly dominate, and that climate variables, if they play any role at all, would add only a marginal, unmeasurable nudge to systems already under far greater geological stress.
Where the Earthquake Theory Comes From
Much of the recent online alarm traces back to a handful of niche climate-and-earthquake monitoring sites and older fringe theories from geology blogs that argue El Nino itself is caused by deep ocean volcanic and seismic activity, rather than the other way around, a claim that runs contrary to the mainstream understanding of ENSO atmospheric-oceanic mechanics.
It is also worth noting that big earthquakes happen somewhere in the world every year, El Nino or not. When a major quake coincides with a high-profile climate event, it is easy for the timing to look meaningful even when the underlying physics do not support a causal link.
Is the Worst Yet to Come?
For temperature and weather extremes, yes. Forecasters expect this El Nino to keep strengthening through the final months of 2026 before likely peaking around the turn of the year. NOAA’s July outlook gave a 97% chance of El Nino conditions persisting into next spring, and scientists widely expect 2026, 2027, or both to set new global temperature records once the full effect of this event plays out.
Regarding earthquakes, there is no credible scientific evidence to suggest that a Super El Nino could cause a spike in global seismic activity. Experts continue to advise that earthquake preparedness should focus on known fault lines and local building codes in seismic zones, rather than on ocean temperature changes.
The Bottom Line
The temperature aspect of this story is thoroughly documented and should be taken seriously; a record or near-record El Nino occurring on an already warming planet raises concerns for 2027.
In contrast, the link between earthquakes and ocean warmth remains speculative at best, with mainstream seismologists attributing ground shaking primarily to tectonic activity rather than ocean temperatures.
