There are different types of Mass Movement those being mudslides, rock falls, debris flows, earth flows, and landslides. These movements on land can occur from slump (rotations landslide), soil slip (translational landslide), and rock slide (Lateral spread). They will all look different and happen because of gravity and the way it is pulling on land.
On April 27, 2024 a landslide occurred on Therasia, an island on Greece. Although their was no damage done and no one got hurt, it can feel really scary watching a landslide happen. This island is prone to landslides because of steep slopes, high seismicity, and the island having interlayered volcanic lava along with pyroclastic rocks(formed by explosive volcanic eruptions), that causes the slope to be unstable. Below is a screenshot from a video of the landslide on the island.
Some safety measure Greece takes for landslides are putting signs(in english, Greek, and French) in areas that are at risk, traffic restrictions (vehicle restrictions in Ammoudi to limit crowding when Anthinios Port is being unloaded. Minister vassilies Kikilias has informed the country that there are projects set to reduce landslide risk, that means "support is needed along the caldera area, slope support at high risk points and corresponding structural interventions"

Hi! I really enjoyed reading your post. You did a great job explaining the different types of mass movement and how they can occur due to gravity and slope conditions. The example of the Therasia landslide is especially fascinating, and it’s good to know that Greece is taking proactive safety measures to reduce the risks. It must have been pretty alarming for those who witnessed it, but I’m glad no one was hurt. Keep up the great work!
ReplyDeleteHello there. I love your explanation about the different types of mass movements and how that can be caused by gravity and slope changes. I am glad that Greece is taking the careful measures to reduce the risks and keep people safe.
ReplyDeleteHey Rosalinda,
ReplyDeleteDriven by gravity, mass movements such as mudslides, rock falls, debris flows, earth flows, and landslides can take many different forms, such as slumps (rotational landslides), soil slips (translational landslides), or rock slides (lateral spread). Therasia, a Greek island prone to landslides because of its steep slopes, high seismic activity, and unstable volcanic rock layers, experienced a landslide on April 27, 2024. Even though there were no reported injuries or damages, seeing a landslide might be frightening. According to Minister Vassilies Kikilias, Greece employs safety measures such multilingual warning signs, traffic limits, and slope support projects along the caldera to reduce the risk of landslides. She also stressed the importance of structural interventions at high-risk areas.
Hi Rosalinda! Landslides, like the one on Therasia in 2024, show how important it is to pay attention to warning signs in areas prone to natural disasters. The signs and safety measures Greece has in place are really important for protecting both locals and visitors. These precautions, combined with the projects to stabilize the land, help reduce the chance of bigger disasters in the future!
ReplyDeleteThank you for sharing about mass movements and the recent landslide on Therasia, Greece. It's interesting to learn how factors like steep slopes and volcanic rock contribute to landslide risk. The safety measures, such as multilingual warning signs and traffic restrictions, are vital for protecting people in vulnerable areas. It’s great to hear that the government is taking steps to reduce landslide risks through structural interventions.
