Powerful Earthquake Rattles Italian City Of Naples With Rubble Crashing Down On Cars Amid Growing Fears Of Huge Volcanic Eruption

A 4.0-magnitude earthquake shook Italy‘s volcanic region of Campi Flegrei west of Naples last night as shocked residents posted videos of cars being pelted by rubble amid the worst of the tremors.

The quake – the latest in a series of tremors this past week – caused panic among residents who spilled out into the streets amid fears it could be the prelude to a volcanic eruption.

The area around the Campi Flegrei (Phlegraean Fields) volcano, which last erupted in 1538, has been the scene of increased seismic activity in recent days with a series of tremors.

Campi Flegrei is the largest active supervolcano in Europe – some half a million people live in the regions around it and would be in grave danger in the event of an eruption.

It comes as a joint study by Italy’s National Institute of Geophysics and Volcanology (INGV) and University College London (UCL) found in June that the volcano was edging towards ‘breaking point’ and in an ‘extremely dangerous state’.

On Wednesday, a 4.2-magnitude quake was recorded, the strongest the area has seen in 40 years, which was felt as far away as Rome.

About 7 to 9 miles (12  to 15 km) across, Campi Flegrei is the largest active caldera in Europe and extends west from the outskirts of Naples to the Tyrrhenian Sea. About a third is partially submerged beneath the Bay of Pozzuoli; the remaining two-thirds are home to more than 360,000 people. The caldera is marked by the yellow dashed line; ground movement has occurred across the central region marked in blue

INGV director Mario Di Vito warned that ‘it is possible that there will be tremors of greater intensity’ in the near future.

‘The seismic activity continues and will continue. There is no doubt about this,’ he said.

Another INGV official Giuseppe De Natale said he had instructed Naples city council to conduct safety checks on the city’s hospitals, schools and public buildings.

Meanwhile, civil protection minister Nello Musumeci cautioned against alarmism, but admitted he had planned meeting with officials in Naples to expedite the drafting ‘of exodus plans in the event of an emergency’.

Campi Flegrei is a collapsed supervolcanic caldera consisting of several craters and volcanic edifices.

A series of small scale earthquakes and tremors have steadily weakened the caldera in recent decades, causing pressure to build up beneath the surface.

The INGV say continued tremors will only cause pressure to increase, cultivating the required conditions for an eventual eruption.

Professor Christopher Kilburn at UCL’s Earth Sciences department said that Campi Flegrei is more prone to a ‘rupture’ – a break or fracture through the rock that makes up the body of the volcano.

‘It’s a natural result when the volcano is stretched as pressure builds up underground,’ Professor Kilburn told MailOnline.

‘Once a rupture has occurred, it will be easier for volcanic fluids to escape.’

A rupture could open a crack through the Earth’s crust, although the magma still needs to be pushing up at the right location for an eruption to occur.

Campi Flegrei is defined as a supervolcano because it has the potential to produce a magnitude eight eruption, capable of discharging more than 200 cubic miles of material.

It last erupted when Henry VIII was last on the English throne, and this event came following an interval of about 3,000 years.

But the researchers warn that large calderas of this sort frequently pass through several decades of unrest before they erupt.

Campi Flegrei has been restless since the middle of the 20th century, which is of a particular worry to scientists.

It has exhibited several two-year periods of unrest in the 1950s, 1970s and 1980s causing small, local earthquakes and ground uplift due to movement of magma beneath the surface.
