This is the shocking moment when a giant landslide descended into the sea in Santorini, covering a village with dust as tourists looked on, merely six months after earthquakes had shaken the holiday island.

A large section of land abruptly collapsed in the clifftop village of Imerovigli on Sunday afternoon after extensive construction activity weakened the ground.

It comes just months after the paradisal island was shook by more than 20,000 earthquakes between January 26 and February 22 earlier this year.

A month-long state of emergency was declared by the country as earthquakes hit the volcanic island every ten minutes, prompting around 11,000 residents—more than half of Santorini’s population—to evacuate.

The recent landslide has been attributed to the combination of seismic activity and excessive construction, which are believed to have turned the fragile soil into unstable ground.

The frightening footage, captured by Santorini residents, depicts a massive cloud of thick dust engulfing the serene town, famous for its whitewashed buildings with blue domes.

‘Santorini is an island with fragile geomorphology, and adding the stress of overdevelopment, the risk of landslides escalates,’ local experts, who quickly arrived at the scene, told Greek news outlet Protothema.

The stretch of land that collapsed was under particular pressure due to the construction of a new building, the report said. 

According to Efthymios Lekkas, Professor of Dynamic Tectonics and Geology at the University of Athens, Santorini is prone to landslides because of its steep slopes, high seismicity, and the island’s geological morphology – consisting of interlayered volcanic, lava, and pyroclastic rocks.

The rocks erode easily, leading to instability in the ground.

He added that ‘uncontrolled’ building in the caldera zone of Santorini continues to expand downward – despite plans by the Greek government to ban new developments.

As a result, hotels are built on steep, dangerous slopes with weak rock composition,  making them vulnerable to landslides – especially amid increased tremors. 

Earlier this year, as the island was gripped with earthquakes, Greek prime minister Kyriakos Mitsotakis announced £2.5million funding for an emergency evacuation route from the south of Santorini to be built.

Hotel owners were even asked to drain their pools due to concerns that overflowing water could destabilise buildings in a quake.

Many who stayed on the island slept on the street with their mattresses, too scared to stay in their homes in case they collapse.

Other residents built makeshift tsunami defences using sandbags along Monolithos beach, where buildings sit dangerously close to the water.

Seismologists said the quakes were the result of tectonic plate movements, not volcanic activity, despite Santorini sitting on the Hellenic Volcanic Arc – a chain of islands formed by ancient eruptions.

The strongest earthquake to shake the island earlier this yea was reported as a 5.3-magnitude on February 10.

Greece sits on multiple fault lines and is one of Europe’s most earthquake-prone countries, but experts said the level of activity was unprecedented.

In July, Italy was inundated by landslides caused by flashfloods that destroyed bridges, washed away cars and triggered an evacuation.

Roads were submerged in water and mud, trapping cars that tried to ford the flow of rain.

Though the damage in the area was extensive, no one was injured or killed by the extreme weather.
