Santorini Volcano Returns to Dormant State

After three years of increased activity the volcano on the Greek island of Santorini has returned to its dormant state, according to the newspaper Kathimerini. Experts from the Institute of Geology and Mineral Exploration (IGME) spoke with the Greek newspaper after their annual inspection of the Santorini volcano, noting that the seismic activity and physicochemical parameters have returned to normal levels, while the changes to the volcano’s rim have stopped. Furthermore, they added that the repercussion of a possible eruption would not be as horrible as everyone believes. “We know that even if there was an eruption in 2011, it would be a perfectly manageable situation, similar to that of 1925-1926,” said Giorgos Vougiouklakis, a scientist at IGME. “Volcanoes always give you a warning. If the volcano is systematically monitored and the state is well-prepared, an eruption could even work as a magnet for tourists. This is the sort of situation we are talking about, so let’s not engage in scaremongering.” Santorini is the most active volcanic centre in the South Aegean Volcanic Arc, though what remains today is chiefly a water-filled caldera. The volcanic arc is approximately 500 km long and 20 to 40 km wide. The region first became volcanically active around 3–4 million years ago. The island is the site of one of the largest volcanic eruptions in recorded history: the Minoan eruption, which occurred some 3600 years ago at the height of the Minoan civilization. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of meters deep and may have led indirectly to the collapse of the Minoan civilization on the island of Crete, through a gigantic tsunami. Another popular theory holds that the Minoan eruption is the source of the legend of Atlantis.

Crazy Image Shows What The Largest Volcano In The Solar System Would Look Like On Earth

Mt. Everest might be the tallest mountain on Earth, but it's nothing compared to the tallest volcanic mountain in the solar system, Olympus Mons on our red cousin Mars. John Brady at Astronomy Central shows, in the image below, what this gargantuan feature would look like if it were on the continent of North America — it would completely cover the state of Arizona! Named for Mt. Olympus — the highest mountain in Greece — Olympus Mons towers 16 miles above the Martian surface — three times taller than Mt. Everest. This mountain is also the largest volcano in the solar system with a caldera at its summit that is 53 miles across. Here's what that looks like compared to Everest: The caldera is easily visible as the small, central circle in the NASA picture below of Olympus Mons, the zit-looking mound in the upper center, which Brady used for his comparison image. With a diameter of 375 miles, Olympus Mons is part of the largest volcanic region on Mars called the Tharsis Montes. The region spans 2,500 miles across the surface of Mars and contains 12 large volcanoes that are up to 100 times larger than any volcanoes on Earth. Like the volcanoes that formed the Hawaiian islands, Olympus Mons is a shield volcano, which is named after its shape, which resembles a warrior's shield. Shield volcanoes erupt lava that flows more easily than lava from some other eruptions, which means the lava travels a further distance before cooling and hardening giving shield volcanoes their distinctive shape, which you can clearly see in the NASA image below: Eruptions, which could last for hundreds of years at a time, and subsequent lava flows built a ridge up around the central peak of Olympus Mons, shown in the computer-generated view below. This ridge is estimated to be 6 miles high — higher than the tallest point on Mt. Everest, which is 5.5 miles above sea level. Scientists estimate that the last time Olympus Mons erupted lava onto the Martian surface was between 20 and 200 million years ago — around the same time that dinosaurs roamed the Earth While some scientists think that this last eruption on Olympus Mons marks the last breath of volcanic activity on Mars, others suggest this monstrous volcano is still active despite being dormant for millions of years. A scary thought when you consider the volcano's colossal size. Olympus Mons is the largest planetary mountain in the solar system, but there's a mountain on the asteroid, Vesta, that is the largest mountain around. Called Rheasilvia, the mountain is a mere 315 feet higher than Olympus Mons.CHECK OUT: Insane GoPro Video Shows Man Rappelling Into Volcano SEE ALSO: Crazy Image Shows What One Of Jupiter's Moons Looks Like Compared To Earth Join the conversation about this story »
