Chapter 11- Coastal Hazards

 This week the focus is Coastal Hazards, for Greece the main coastal hazard is erosion and sea levels rising. Erosion is when "geological processes of earth materials is taken or removed from one place to another such as soil or rocks by wind, water, or ice".  One third which is 28.6% of the Hellenic coastline is being affected by erosion and the rate is 0.3-0.5 meters a year, the Aegan coast is  prone to erosion mainly when sea level rises more than 3.5mm per year. This is caused by climate change and deforestation in Greece, and due to having dams or river channelization(helps with river flow to make it easier to navigate and controls flooding) there has not been as much sediment supply which helps shape landscapes, ecosystems, and coastal landforms in Greece. 

Greece has put in place hard engineering structures in order to protect the coast from eroding, those being seawalls, groins, breakwaters (protects against tides), and rock armoring as well. Around 15% of the coastline that is suffering from erosion is being protected. Other protections set in place are taking care of the beaches so there is a loss of beaches in Greece, sediment recycling, and stabilization of the dunes.

    I really enjoyed your post this week about Coastal Hazards. Your post was well written out and I liked how you explained what erosion is, Spain also has erosion problems and rising sea-levels. Another thing I liked is how you included the statics and their outcomes. Great job!

    This Weeks post about coastal hazard was really interesting as I got to learn more about how this disaster affects Greece. Great job

Week 8: Mass Wasting Events

  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 (...

Introduction-Week 1 Material

     The country I decided on was Greece! I have always found it interesting and wish to travel there one day. Greece has many different islands and 80% of Greece is made up of mountains, one could discover so much in different islands or islets (a small island). I can't wait to read more about Greece and it's History. Hazards are when an earthquake, tornado, windstorms, etc. may occur and it can be a threat. A disaster includes a hazard but it is in a specific area and declared a state of emergency and could possibly need international help. With that being said, a catastrophe involves a hazard that really effects everything around it. It does a lot of damage to human life, wild life, and property which takes a big amount of money and time to recover.  Resources:  Introduction-Ch1 https://www.trafalgar.com/real-word/facts-greece/

Week 2- Plate Boundary in Greece

  Greece is located in the middle of the Eurasian Plate and African tectonic plate. Greece is known to be one of the most earthquake active country in Europe. The earthquakes go up to 7.2 inches magnitude. It was interesting find out out that Greece was in between two plate boundaries and not only one.                                          Tectonic setting of the Aegean (Papazachos et al. 1998) References: http://erasmus.ntua.gr/en/natural_phenomena/#:~:text=Greece%20is%20located%20at%20the,Plate%20and%20the%20Eurasian%20Plate. http://erasmus.ntua.gr/en/natural_phenomena/#:~:text=Greece%20is%20located%20at%20the,Plate%20and%20the%20Eurasian%20Plate.
