North Sulawesi is in a complex tectonic interaction which is the relative movement of three Eurasian macro plates, the Pacific plate, the Philippine plate, and the Maluku Sea microplate. The active tectonic movement results in high earthquake activity in the region of North Sulawesi and its surroundings. This results in the importance of accurate earthquake parameter information, one of which is by conducting research on local wave velocity. The purpose of this study is to determine the velocity of 1D P waves and relocate the earthquake hypocenter and determine the correction stations in North Sulawesi and surrounding areas with coordinate boundaries 0.17166°S- 2.742781°N and 119.5212°E- 125.5067°E using the Couple Velocity-Hypocenter method with Velest software. The results of simultaneous inversion processing are carried out until the 50th iteration which obtains the wave velocity fluctuates at several depths but in general, the denser layers of the earth's compilers will increase the wave velocity, the improvement of the RMS from an average of 1.71 to 0.49 and the correction of the stations obtained is at intervals of 0.39 to 20.91.

In analyzing the risk of an earthquake it is necessary to have parameters used, one of which is the maximum ground acceleration or Peak Ground Acceleration (PGA). Some data is not fully available on the accelerometer network. Therefore, the purpose of this study is to select an appropriate GMPE equation to estimate the PGA size in Manado City. The selection of the GMPE equation in this study considers the relative difference value and the correlation coefficient in the GMPE equation. Based on these results, the formulation of Kanno, et al. (2006) was chosen to be the initial GMPE equation in the Manado City area. The equation is modified to get an equation with new coefficients. From the results of this equation, it can be determined that the city of Manado often experiences any type of earthquake and also gets the mitigation that needs to be applied.

Ranolewo, located in the Toraget Village, North Langowan District, North Sulawesi, is recognized for its geothermal manifestation in the form of hot springs, indicating the area's geothermal potential. The aim of this study is to characterize the fluid type of the hot spring manifestation in Ranolewo using geochemical methods. The findings reveal a temperature of 52°C at the manifestation site, with a pH level of 5.6, indicating acidic properties. The fluid type identified in the Ranolewo hot spring area is sulfate water. This is attributed to chemical analysis results showing sulfate as the dominant element, along with the presence of SO4 gas. Sulfate water typically forms at shallow depths due to the condensation of geothermal gases nearing the surface. Geothermal gases, comprising air and carbon, are generally dissolved within fluid content in deeper zones but separated from chloride water. Sulfate water is commonly found at the boundary area, not far from the main upflow zone.

The stability of the atmosphere can affect the weather conditions in an area. This study aims to compare atmospheric stability carried out in Lake Linow which has two surfaces, namely the surface of geothermal manifestation and the surface without geothermal manifestation. In determining the stability of the atmosphere, researchers use the Richardson number method. To determine atmospheric stability using the Richardson number, data on wind speed and temperature at each altitude are needed. The measured height is 2 meters and 4 meters from the surface. The results of this study show that on the surface geothermal manifestations have unstable atmospheric stability with Richardson numbers -1.4729 to -0.1420, while on the surface without geothermal manifestations have 3 states of atmospheric stability, namely: stable, neutral, and unstable, with Richardson numbers -1.1316 to 0.9808. Therefore, it can be concluded that the state of the atmosphere on the surface of geothermal manifestations is more unstable, compared to surfaces without geothermal manifestations.

To meet future energy needs, the Indonesian government has developed alternative energy sources: geothermal energy. Rano Raindang is one of the areas with a geothermal field due to several geothermal manifestations, such as hot springs. This study aims to examine the fluid type, the reservoir temperature estimation, and the functional group of hot springs. The method used is a geoindicator of Na, K, Mg, Cl, SO4, and HCO3, combining spectrophotometry and FTIR spectroscopy. Research results show that the type of hot spring fluid around Rano Raindang with geoindicators Na, K, Mg is immature waters, this is because the type of hot spring fluid around Rano Raindang has undergone a mixing process, while the geoindicators Cl, SO4, HCO3 are bicarbonate (HCO3) types. This corresponds to the results of measurements using FTIR spectroscopy. The estimated reservoir temperature in the area is 193.66 °C and is included in the medium-temperature geothermal system, as the temperature around Rano Raindang is between 125–225 °C. The functional group of hot spring molecules around Rano Raindang has functional groups C=O and O-H.
