Abstract
This study examines the seismograph rooms and stands in 10 out of 28 weather observation facilities dating back to the Japanese colonial period in Korea. The analysis is based on architectural drawings from the National Archives of Korea. During the 1920s, seismograph rooms were selectively integrated into observatories and their extensions. These rooms were typically located in the basement or semi-basement and shared space with the barometer room. Inside these rooms, T or L-shaped seismograph stands made of bricks were installed and positioned at a higher level than the wooden floor. Moving into the 1930s, the seismograph rooms shifted to ground level, featuring standalone concrete seismograph stands with rectangular or square shapes. Simultaneously, concrete was applied to the floor structure. In these cases, the height of the concrete stand matched that of the room floor. The findings of this study are expected to provide valuable insights into the preservation and utilization of the seismograph stand's foundation, which was excavated at the Seoul Meteorological Observatory in 2020.
