Abstract

Indonesia is an area that is prone to natural disasters, one of which is earthquakes. Several strong earthquakes have occurred in North Sulawesi, causing extensive structural damage. This study aims to determine the seismicity parameter values a-value and b-value or to determine the level of fragility and seismicity in North Sulawesi. The earthquake data used is secondary data for the period 2019-2023 obtained from the Manado Geophysical Station, BMKG, North Sulawesi. The data obtained includes the date, time of occurrence, latitude, longitude, magnitude and depth of the earthquake. This study uses the Guttenberg-Richter method which is processed using Zmap software. From the distribution of earthquake data, it is known that a major earthquake occurred in 2019 with a magnitude of 7.1. The results of this study show that in 2019 it had a high a-value, namely 8.13. This shows that in 2019 in the North Sulawesi area there were relatively more earthquakes. The b-value results in this study show that in 2022 it has a high b-value, which is 1.32. This is influenced by elastic rocks that experience stress so that there is a change in shape or deformation called rock fragility. Seismicity vulnerability in the North Sulawesi region for the period 2019-2023 ranges from 6.16 to 8.13 with a rock fragility level range from 0.91 to 1.32

Abstract

Geothermal is a natural heat resource derived from the interaction between heat that has been emitted by hot rocks and water. Geothermal energy is pollution-free, sustainable, or renewable. Geothermal energy appears on the surface in the form of geothermal manifestations such as warm ground, steamy ground, hot springs. North Sulawesi has the potential to be the location of direct and indirect geothermal development. This study aims to determine the fluid type and molecular functional groups of hot springs in Sawangan Village, North Minahasa Regency, because this location has geothermal potential. By using the geochemical method of making diagrams , it is known that the fluid type of hot springs in Talawaan Bantik Village, Wori District is of the Birkabonat type and the molecular functional groups are C = O and O-H, where the parent chain, C, O and H bind (Bicarbonate) which corresponds to the fluid type results.

Abstract

The need for energy in everyday life is very important, geothermal energy has the potential to become an energy source for power plants. Indonesia has one of the largest geothermal potentials, because Indonesia is located in the Ring of Fire. One of the provinces known for its abundance of geothermal energy is North Sulawesi. The purpose of this study is to determine the characteristics of this geothermal manifestation. The method used is the Cl-Li-B Geoindicator to determine the outflow zone or upflow zone of a geothermal system. The results of the study show that the manifestation has a temperature of 39⁰C with a pH of 6.39 containing a higher chloride (Cl) content than Lithium (Li) and Boron (B), the chloride (Cl) content has a percentage of 82.3529% while for Lithium (Li) has a percentage of 11.7647% and Boron (B) has a percentage of 5.8823%. The data shows that of the three parameters studied, the relatively low B/Cl ratio indicates that the hot spring comes from an old geothermal reservoir and chloride (Cl) has the highest percentage of content, it can be concluded that this manifestation is in the outflow zone
