The vertical seismic deformation of the Palu earthquake magnitude of 7.4 on the Richter Scale, which occurred on September 28, 2018, has been analyzed using InaCORS (Indonesian Continuously Operating Reference Stations) stations. The stations used are CBAL, PALP, CTOL, CMLI, CPAL, and CBIT. The analysis was conducted using GAMIT, GLBOK, and GMT software. The analysis focused on the period of 100 days, starting from August 6, 2018 (DoY 218) to November 28, 2018 (DoY 318), encompassing the preseismic, coseismic, and post-seismic phases. During the preseismic phase (DoY 218-270), the InaCORS stations experienced a slight deformation ranging from -10.9353 mm to 6.5525 mm. Tectonic manifestations influenced the direction of movement in Sulawesi. The deformation significantly increased in the coseismic phase (DoY 271-272). The InaCORS stations experienced deformations ranging from -169.8 mm to 8.755 mm, which differed in the direction from the preseismic phase. The stations in the northern region predominantly moved towards the north, while those in the southern region moved towards the south. During the post-seismic phase (DoY 273-318), the movement of the InaCORS stations followed the direction of deformation observed in the coseismic phase. However, the displacement was relatively smaller, ranging from 11.5909 mm to 17.23733 mm.

The position of our country is included in the area Ring of Fire, where 90% of earthquakes on earth will occur in this region. Earthquakes in West Sumatra (2009), Mentawai (2010), Lombok and Palu (2018) have claimed more than 10,339 lives and more than 100,000 heavy damage to buildings. Building walls are generally made of brick or adobe, but these two materials have several disadvantages including weight and brittle. As a result of its considerable weight, it will increase the dead load of the structure so that the earthquake load will also increase. Thus, lightweight and clay materials (ductile) will be better if used as earthquake-resistant building walls and the level of risk is lower. Prefabricated sandwich panels produced by PT. BUILDING TECHNOLOGIES INDONESIA within BUKAKA TEKNIK UTAMA Tbk Group. to be a series of cyclic load tested full scale wall constructions. The conventional panel circuit model obtained the behavior of each swaying wall segment as an independent individual panel. Cyclic test results up to drift 12 were obtained with a maximum load of 4.245 kN with a maximum displacement of 106.28 mm compressive direction and a maximum load of 1.425 kN with a maximum displacement of 75.68 mm pulling direction. Deviation behavior is obtained that continues to increase as horizontal loads increase, but not until structural damage occurs in the series of 3 sandwich walls. This condition is a positive thing in the development of buildings with light materials to reduce the magnitude of the earthquake force and minimize damage and casualties.
