Near Naples, Italy, the enormous Campi Flegrei caldera has raised concerns among scientists. Recently, there have been earthquakes, gas emissions, and ground shifts that suggest this dormant giant may be awakening. Given its extensive history of devastating eruptions, it is understandable that the world is observing closely. Researchers are currently investigating the activities occurring beneath the surface of this volcanic region and the potential implications for nearby residents. Should an eruption occur, this Italian supervolcano could have repercussions for the entire planet.
What We Know About the Supervolcano
Campi Flegrei, also referred to as the Phlegraean Fields, is a large volcanic area situated near Naples. Importantly, it is not just any volcano; it is a supervolcano capable of affecting the entire globe. Over the years, this ancient crater has become home to millions. The supervolcano’s historical eruptions have significantly influenced both history and the surrounding landscape. Currently, it is exhibiting signs of unrest that have scientists and local authorities feeling anxious. Due to its size and geographical position, this Italian volcanic region is considered one of the most hazardous on the planet.
Recent Earthquakes Raise Alarm
In May, a significant earthquake measuring 4.4 on the Richter scale struck the Phlegraean volcanic fields. This was the most powerful quake recorded in 40 years. In the last six months, over 3,000 smaller tremors have disturbed the area. Clearly, this is not a coincidence. Scientists suspect that these seismic activities are indicative of magma movement beneath the caldera. While not every tremor results in an eruption, the intensity of this swarm is too significant to overlook. As a result, experts are closely monitoring each new seismic event.
Gas Emissions Surge to Record Levels
In addition to the trembling ground, there is another alarming indication in the volcanic region: unprecedented gas emissions. Daily measurements by scientists indicate the release of 4,000 to 5,000 metric tons of carbon dioxide. This quantity is significant for a volcano that has remained largely dormant for centuries. As magma in the Flegrean volcanic area ascends towards the surface, an increased amount of gas is released. Consequently, this rise in gas emissions serves as a clear alert that the Campi Flegrei supervolcano may be on the verge of an eruption.
Crust Cracking Under Pressure
Scientists are also observing indications that the crust beneath the caldera is transitioning from bending to cracking. This represents a significant change. The formation of cracks in the rocks provides easier pathways for magma to ascend. Therefore, researchers believe that the Italian supervolcano may be edging closer to an eruption. This serves as one of the most evident warnings for those monitoring the volcanic area near Naples. After all, each crack facilitates the ascent of magma.
A City in the Crosshairs
Naples and surrounding towns such as Pozzuoli are situated directly adjacent to the Campi Flegrei volcanic region. Millions of individuals reside in this area. Unlike volcanoes located in isolated regions, this one poses a threat to populated cities filled with residences, educational institutions, and medical facilities. Should the supervolcano erupt, lava, ash, and hazardous gas clouds could swiftly wreak havoc on these communities. Therefore, local officials recognize the necessity of having emergency preparedness plans in place for the Naples volcanic region.
Campi Flegrei’s Historic Eruptions Leave Clues
Examining the historical eruptions of Campi Flegrei reveals its immense power. Approximately 40,000 years ago, it produced one of the largest known eruptions on Earth. This event may have contributed to the extinction of Neanderthals in Europe. Additionally, the last eruption of the caldera in 1538 resulted in the formation of Monte Nuovo within a matter of days. These historical eruptions illustrate the potential of the Italian volcanic zone when it eventually awakens. Thus, history serves as an essential reference for forecasting future hazards.
The Ground is RisingSince 2005, researchers have observed the ground in Pozzuoli elevating by almost five feet. This gradual and consistent rise is referred to as bradyseism. It happens when magma and gas push upwards, resulting in the swelling of the Earth’s surface. In the Campi Flegrei volcanic region, this elevation is not without consequences. On the contrary, it serves as an indication that magma is moving closer to the surface. Each inch of uplift provides scientists with evidence that the supervolcano is becoming active beneath.

The Global Impact of the Italian Supervolcano
An eruption from the Campi Flegrei caldera would extend beyond the borders of Italy. Ash from a significant explosion could spread across Europe, disrupting flights and harming agriculture. Similar to the eruption of Mount Tambora in 1815, which led to a drop in global temperatures, a future eruption could also result in a worldwide temperature decrease. This would consequently impact food supplies and pose economic difficulties far beyond the slopes of the Italian supervolcano. Thus, the influence of supervolcanoes spans continents, illustrating the immense power of these natural phenomena.
Watching and Waiting
The exact timing of the Campi Flegrei eruption remains uncertain. Volcanoes can be erratic, often remaining dormant for centuries. Nevertheless, scientists are monitoring every tremor and gas emission using satellites and sensors. Their ongoing data collection ensures that residents in the Naples volcanic region are kept informed and prepared. While nature ultimately determines when the next eruption will occur, being vigilant and ready can significantly impact outcomes. Therefore, for the time being, watching and waiting are the only viable options.
A Sleeping Giant’s Uncertain Future
Currently, the Campi Flegrei caldera lies in a state of rest, though not completely inactive. Recent seismic activity, increasing gas emissions, and rising ground levels all indicate a restless supervolcano. Scientists concur that this supervolcano possesses the capability to alter everything in an instant. As they maintain vigilant observation, the world also waits. This situation serves as a reminder that the unpredictable forces of nature can shape our environment in ways that are beyond our complete control.
