Two of Greece’s most dangerous volcanoes share an underground link

A January earthquake swarm exposed shared plumbing between Santorini and Kolumbo.

 

An intense swarm of earthquakes around Greece’s Santorini Island in January has revealed a fiery underground link between two neighboring and historically explosive volcanoes.

Analyses of seismic activity from June 2024 through February 2025, along with changes in the island’s surface elevation, suggest that the same well of magma feeding the Santorini volcano may also supply the submerged Kolumbo volcano, just seven kilometers away, researchers report September 24 in Nature.

Complex, shared magma plumbing systems can complicate the interpretation of earthquakes and signs of imminent eruptions, say Marius Isken, a geophysicist at the GFZ Helmholtz Centre for Geosciences in Potsdam, Germany, and colleagues. This study, they say, highlights the need for real-time, high-resolution monitoring to improve volcano warnings.

Santorini is known for a catastrophic volcanic eruption around 1560 B.C. that contributed to the end of the Minoan civilization and caused widespread devastation, including earthquakes, tsunamis and possibly a volcanic winter. Kolumbo is no slouch either, erupting most recently in A.D. 1650.

When a swarm of over 1,200 earthquakes rattled the region early this year, Greece declared a state of emergency, fearing an imminent eruption. Although no eruption ensued, the abundant quakes allowed Isken and colleagues to examine the subsurface and better understand how and where magma moved.

While NASA Alters/Warms Greece Temperature Data, Cold And Unusual Snow Keep Coming Anyway!

by Kirye and P. Gosselin, April 10, 2020 in NoTricksZone

So what’s going on?

NASA and other government agencies keep telling us that the globe is warming and ice becoming more rare, yet when look out the window, things often appear to be going the opposite direction.

Rare cold, snow grip Greece

For example, the Greek Reporter here informed how a “rare spring snow” blanketed large parts of northern Greece. It reported: “Of course, Northern Greece is used to low temperatures and snow, but even for their standards, such an intense snowfall in April is rare.”

Moreover, the widely read Electroverse weather site here reported how southeast Europe had seen its “coldest April morning in a decade”, potentially causing widespread crop damage.

So why are such events happening when they aren’t supposed to be?

Altering: from cooling to warming

Today we look at the NASA data from two stations in Greece: Makedonia and Larissa, shown below:

Israel, Cyprus, Greece and Italy agree on $7b. East Med gas pipeline to Europe

by Toi Staff, November 24, 2018 in TheTimes.of.Israel

HE LONGEST, DEEPEST UNDERWATER GAS NETWORK IN THE WORLD

Greece, Italy, and Cyprus have reached an agreement with Israel to lay a pipeline connecting the Jewish state’s gas reserves to the three countries, in a major project estimated at costing over $7 billion that will supply gas from the eastern Mediterranean to Europe, as the continent seeks to diversify its energy supply.

According to Hadashot TV, the European Union agreed to invest $100 million in a feasibility study for the project before the agreement was reached over the laying of the longest and deepest underwater gas pipeline in the world.

Using reflective pavements to mitigate urban heat island in warm climates – Results from a large scale urban mitigation project

by G.E. Kyriakodis and M. Santamouris, June 2018, in UrbanClimate

Highlights

Large scale implementation of cool asphaltic and concrete photocatalytic pavements

Extensive monitoring strategy of in situ measurements in the area

Surface temperatures reduction up to 7.5 °C and 6.1 °C respectively in the summer period, while the peak drop was up to 11.5 °C

The maximum air temperature reduction could reach 1.5 °C.

Ageing phenomena may reduce substantially and up to 50% the mitigation potential of cool asphaltic materials.
