Week 5: Volcanoes in the US

 


Greece is quite known for being super active when it comes to volcanoes. Most volcanoes in Greece are somewhat still active and the most important ones are located on the Santorini Island. When sea levels drop the island rumbles as the volcanoes get ready to erupt. Greece has a total of 12 volcanoes that are ready to erupt. 

Something that I found interesting was learning that Santorini tends to consist of islands surrounding the central tip of a volcano poking out of the Aegean Sea. The interesting part, is that the volcano at one point was above water but later due to an eruption during 1600 B.C. then caused the volcano to form a lagoon. 

Researchers researched that when sea level tends to drop at least 40 meters below surface of the volcano the crust above the magma chamber tends to be splintered. The magma stored underneath the volcano then moves upward through the current fractures and can easily makes its appearance on the surface. I also learned that researchers made a stimulation which shows how it takes 13,000 years for cracks to reach the surface and cause the volcano to be awakened, and later after the water rises it takes 11,000 years for the cracks to then be closed and the eruptions to be stopped. 

Some of the volcanoes in Greece are called: Aegina, Gyali, Kos, Methana, Milos, Nisyros, Poros, Santorini (Kolumbo), Santorini (Nea Kolumbo), and Sousaki. A lot of these volcanoes haven’t erupted since back in 140 AD-1950.

    Very interesting research!- Do you know which type of mitigation measures they have to address this hazard?

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
