Week 2: Tectonics

 South Korea is situated in a region that is pretty stable in terms of seismic activity when compared to its neighboring countries, like Japan and China, which are known for their vulnerability to earthquakes. The country's geographic placement on the Eurasian Plate positioned relatively far away from the more active tectonic plate boundaries, contributes to a lower likelihood of experiencing powerful earthquakes. However, this does not mean that South Korea is entirely free from the threat of seismic events. The nation is nonetheless influenced by the tectonic pressures stemming from the movements of the adjacent Pacific and Philippine Plates, which can lead to occasional seismic activity.

Since the onset of full-scale seismic observation in 1978, a total of 770 earthquakes have been recorded in and around the Korean Peninsula, averaging about 26 earthquakes each year. Despite its overall stability, the country must remain vigilant to the potential risks associated with these tectonic interactions, including tsunamis.

    Hi Mallory!
    It was interesting to read how although South Korea doesn't directly land on the Ring of Fire, it still does experience powerful seismic activity due to being a neighboring neighbor to Japan and China, who in fact fall within a portion of the Ring of Fire region. Although your country of choice lands on the other side of the ocean to mine(Guatemala), it was honestly quite surprising to see that they both experience similar hazards: earthquakes, tsunamis, and some volcanic activity; Guatemala however experiencing and being home to greater volcanoes compared to South Korea.

    Enjoyed reading your post!

    Hello Mallory! I also thought your work was very good and interesting. It was cool to read that South Korea averages about 26 earthquakes a year while Nepal has 70 in one year. Big difference between the two, but I bet both places got damage pretty bad.

Week 3: Earthquakes

Image
South Korea is known for its stability, with a geological landscape that is not frequently shaken by seismic activity. In recent years, the country has encountered a few notable earthquakes, one of which occurred in 2016, registering a magnitude of 5.4, and was followed by another in 2017, which reached a magnitude of 5.5. Despite these isolated incidents, South Korea remains largely unaffected by the type of devastating earthquakes that can plague other parts of the world. South Korea’s earthquake catastrophe prevention: In January, the Seoul Metropolitan Government announced a plan to complete the seismic reinforcement of all public facilities by 2030. This initiative, titled the "Comprehensive Plan on Earthquake Disaster Prevention," addresses public concerns regarding the nation's earthquake preparedness, especially following the recent powerful and tragic earthquakes in western Japan, according to the Seoul city government. Key public facilities in Seoul, including r...

Week 5: Volcanoes

Image
  South Korea’s Volcanoes   South Korea has two potentially active volcanoes. The first is Ulleungdo, a 10-km wide island in the Sea of Japan, which is the tip of a submarine volcano that last erupted 5,000 years ago. Despite its beauty, with around 10,000 residents, living on such a volcano poses risks. It has a 3 km wide caldera formed by a significant eruption 10,000 years ago. The second volcano, much larger and more prominent, is Jeju Island, located off the southern coast. Measuring 80 by 40 km, Jeju is a popular holiday destination, especially for honeymooners, and is surrounded by roughly 100 meter deep waters. At its center is Hallasan (or Mount Halla), a mountain that rises to 1,950 meters and features a crater 400 meters wide and 100 meters deep, with a seasonal crater lake called Baengnokdam. This volcano encompasses the entire island, with its mountainous terrain adding to its allure.   Jeju Island has experienced many eruptions, but often not at Hallas...

Introduction to South Korea

Image
The Korean Peninsula, positioned at the heart of Northeast Asia, shares its borders with three major nations: China, Russia, and Japan. Notably, the southern part of the Peninsula, which comprises South Korea and lies below the Military Demarcation Line, occupies around 100,364 square kilometers. This geographical expanse offers a rich tapestry of cultural, historical, and natural significance, making the Korean Peninsula a captivating region in Asia.  About three-quarters of Korea's landscape is dominated by majestic mountains, with elevations highest in the east and gradually descending westward. The northern and eastern regions feature towering peaks over 1,000 meters, shaping the country's character.  As a peninsula, Korea is surrounded by three seas, boasting a coastline of 17,000 kilometers and numerous islands. The East Sea has a smooth coastline and deep waters, while the West and South Seas feature intricate shorelines and abundant islands. Together, these waters crea...
