Taiwan, the east coast of China, or the Philippines. From one to three typhoons can be expected per year. Typhoons usually pass over South Korea in late summer, especially in August, and bring torrential rains. Flooding occasionally causes considerable damage, as do landslides, given the country's generally mountainous terrain. Typhoons often occur from midsummer to early autumn, July, August, and September. Most of the typhoons invading the Korean Peninsula are concentrated during this period, and sometimes indirect effects occur in June and October. Even October has a direct impact and lands.In the summer, the water on the surface of the ocean, which received hot heat, evaporates and rises by convection and condenses, and the latent heat released heats up the surrounding water vapor again to the troposphere interface. In the case of typhoons heading to Korea, most of them fall into Japan, or Jeju Island, Gyeongsangnam-do, and Jeollanam-do are often directly damaged. However, In September 1984, record floods caused the deaths of 190 people and left 200,000 homeless. This disaster prompted the North Korean government to make an unprecedented offer of humanitarian aid in the form of rice, medicine, clothes, and building materials. South Korea accepted these items and distributed them to flood victims. As global warming progresses, the power of typhoons is likely to become stronger. In fact, hurricanes that occur in the Atlantic Ocean, where the average water temperature is 1 to 2 degrees higher than in the Pacific Ocean, are causing much more intensive damage than typhoons in the Pacific Ocean. Since 2013, the typhoon season has been delayed due to climate change, reducing summer typhoons and increasing autumn typhoons. The season came in October 2013, 2020, and November 2019. As a result, the number of super typhoons is increasing.https://www.weather.go.kr/plus/typ/typ_history.jsp Resources and land use Natural resources South Korea produces coal, tungsten, graphite, molybdenum, lead, and has potential for hydropower.

There is also low-level seismic activity, which is common in the southwest. Volcanism Hallasan (elev. ) is considered historically active although it has not erupted in many centuries. Earthquake activity is minimal; however, since 2016, there have
