Week 13: Coastal Erosion

 


For this week I will be discussing coastal erosion. For starters what exactly is this and what effect does it have on Greece? Well, coastal erosion is the process in which local sea level rises causing strong wave action and typically leads coastal flooding that causes rocks and soil to wear down. So what causes this? This is typically caused by various reasons some including the following; hydraulic action,  corrosion by wind & water, and even abrasion. 

I think every country has a possibility of being affected by coastal erosion but depending on the country others are far more impacted depending on the location and circumstances. My country is Greece which is what I will be further explaining for this week and the effects/impact it has on Greece. Due to coastal erosion Greece has been severely impacted causing a massive amount of wreckage in nearly a third of Greek beaches. Greeces’ coastline tends to be 15,000 km long being 60% mainland and the rest of it being 40% just islands. Due to sea level increasing due to the circumstances the beaches sustainability will be questioned due to beach erosion increase.

A project called “The Space For Shore” project provides various materials for specifically coastal erosion monitoring this is used by Earths observations. According to the article, “Monitoring coastal changes in Greece,” it states “ The results highlight the fragility of Greece's coastline and indicate the likelihood of coastal erosion increasing in the coming years. Over the 1995—2020 period, around 40% of the coastlines analyzed have shown 'progradation' which is the seaward growth of beaches caused by the progressive build-up of sediment. The team found that nearly 10% of the studied coastal areas are subject to erosion greater than 3 m per year.” (Pg. 3). Meaning that due to the studies being made it has shown researchers that 10% of the overall studied costal areas have been subjected to erosion and is greater than 3m per year which means Greeces’ beaches are subjected to being impacted.

    Great coastal reflection!- Looking forward to the connection with climate.

    Hi Maritza, I like how much in detail you went to explain the different types of coastal erosions in Greece. It's great that there's a project that is monitoring these erosions so that they can find a way to limit or predict Greece's coastal beaches from being impacted. Do you think because of the rate of 3m per year that Greece's beaches can be gone by 2100? Thank you so much and great post!

Greece Tectonic Plates: Week 2

Image
For this week in my blog post I’ll be exploring Plate Tectonics and the importance of knowing plate boundaries at that location. As you guys are aware my country is Greece and with a little research I was able to find out that the tectonic plate for Greece is called “The Aegean Sea Plate” which can also be referred as either Hellenic plate or Aegean plate. The Tectonic plate in Greece is located in the eastern Mediterranean Sea which tends to locate under Southern Greece as well as Western Turkey! If you weren’t already aware, Greece is tectonically active but why? Well, for instance earthquakes are related to the convergent plate boundary which then tends to span the boundary of Southern Greece. I also learned that although earthquakes are common in Greece the most common earthquakes tend to occur in the Gulf of Corinth where it’s the most seismically active! The three main plates are; Eurasia, Aegean Sea, and the African Plate. I found it interesting to learn that the Aegean plate go

Greece Earthquakes and Seismicity: Week 3

Image
Due to the tectonic plate that Greece has its super common to earthquakes, Greece is super common with earthquakes because it tends to be one of the most active countries. Earthquakes although they are quite mild are so common that an earthquake took place today and it was 2.3 earthquake near the Aegean Sea. There was also another one that located only 2 miles from Aliartos, Greece that was a 4.1 earthquake. I did some research and also found out that on October 30th, 2020 (not too long ago) had a super strong earthquake that was 7.0 killing at least 80 individuals. Due to the placement of Greece people refer to it as a "box" due to the volcanos that are scattered which would make it difficult to find shelter, earthquakes have a strong potential due to the volcanoes that are still active and even if tend to be monitored by scientists the Nysrios Volcano is still likely to erupt because of how common volcanoes are. Most earthquakes that tend to strike Greece have epicenters wh

Week 8: Mass Wasting Hazards in the US

Image
  For this week I will be discussing the "mass wasting" events about Greece. In this country various individuals are forced to deal with what is called mass wasting, due to the location of Greece landslides, rock falls, mudslides, and etc are super common which this leads to damaging homes and even roads. This typically occurs when gravitational pull is pushing down the rocks down cliffs. Sometimes what can also be the cause is the way mountains are formed/shaped in Greece, in Greece the mountains tend to have not just hard but also soft rocks which can make cliffs be not as stabled and prone to hazards. Just how every other country is trying to find ways to prevent these hazards, Greek authorities have tried finding solutions such as; adding reinforced steel fencing and adding nests around the cliffs. Often times when you visit hiking trails it's for the exact same reason to prevent those who are visiting tourist spots especially Greece that is super known for having a h
