Seismic micro-zonation framework for earthquake risk in Medan-North Sumatera Indonesia using geotechnical engineering survey

Abstract

The micro zonation is very essential to identify the tectonic and geological formation in the study area, and still fundamental for determining the seismic source and establishing a realistic earthquake hazard model. Indonesia is located in the Pacific Ring of Fires, it is constantly at risk of earthquakes, tsunamis, and the eruption of volcanic. In this case, we focused to review the previous study of micro zonation in Indonesia and making the framework of micro-zonation for earthquake risk in Medan-North Sumatra, Indonesia. The goal of this study to illustrate the diversity of methodologies presently in use for the preparation of seismic hazard maps and to evaluate basic principles of zonation for different purposes and at different scales in new planning in Medan, North Sumatera. We select the micro zonation methods and looking for the opportunity for planning the micro zonation based on the literature review. The result of this review, the plan and framework of micro zonation in Medan, North Sumatera will be important and needed for mapping the seismic hazards. The output of seismic micro-zonation map based on the geotechnical engineering survey with the Multichannel Analysis of Surface Waves (MASW), Spatial Auto Correlation (SPAC) and Horizontal to Vertical Ratio (HVSR) for dominant period.

Earthquake detection in mountainous homes using the internet of things connected to photovoltaic energy supply

“…Several cases that often occur due to fatalities, namely the unconsciousness of the occupants of the house due to an earthquake such as being at work, falling asleep and also not having an alarm at home so that the owner of the house is complacent so he cannot run out of the house [4]- [7]. North Sumatra is an area where earthquakes frequently occur due to Mount Sinabung [8], [9]. The occurrence of eruptions due to volcanic eruptions also affects the health of the local community which will endanger the people who live around Mount Sinabung [10].…”
