In the reinsurance industry different probabilistic models are currently used for seismic risk analysis. A credible loss estimation of the insured values depends on seismic hazard analysis and on the vulnerability functions of the given structures. Besides attenuation and local soil amplification, the earthquake occurrence model (often represented by the Gutenberg and Richter relation) is a key element in the analysis. However, earthquake catalogues are usually incomplete, the time of observation is too short and the data themselves contain errors. Therefore, a and b values can only be estimated with uncertainties. The knowledge of their variation provides a valuable input for earthquake risk analysis, because they allow the probability distribution of expected losses (expressed by Average Annual Loss (AAL)) to be modelled. The variations of a and b have a direct effect on the estimated exceeding probability and consequently on the calculated loss level. This effect is best illustrated by exceeding probability versus loss level and AAL versus magnitude graphs. The sensitivity of average annual losses due to different a to b ratios and magnitudes is obvious. The estimation of the variation of a and b and the quantification of the sensitivity of calculated losses are fundamental for optimal earthquake risk management. Ignoring these uncertainties means that risk management decisions neglect possible variations of the earthquake loss estimations.

Research area is around Tanjung Balik, Koto Baru Sub Base, Lima Puluh Kota District, West Sumatra Province. Located along the highway Km 10-15 Riau – West Sumatra and the coordinate around 00˚08'40 '' LU - 0˚11'20 '' N and 100˚45'20 '' BT - 100˚47'00 '' BT. The purpose of research to identify petrography, microstructure, types of landslides and the geological condition. The methods using polarization microscope, stereography, landslide identification survey and geological mapping. The result of study shows the petrography analysis of lithology of study area are classified into three types of rocks are Feldspathic Greywacke, Lithic Arenite, and Slate. Microstructures trending system show the foliation structure that is relatively Southeast-Northwest. Types of landslide which dominates in the research area are debris avalanche and translational landslide. Geological analysis show some of rock units are classified into two units: Sandstone Unit and Slate Unit. Sandstone Unit spread in the northern part of the study area, while Slate Unit spread in the southern part of the study area. The characteristics of these rocks showed Pematang Formation.

In the 2019 legislative elections in West Sumatra, social capital and political capital are one of the ways in which actors can compete with their political opponents, in order to attract the attention of the public to support it. Birner and Witmer state that the concept of political capital makes it possible to study local communities using social capital to achieve political goals, and Bourdieu also said that social capital is in the form of actual and potential resources owned by someone from an institutionalized and ongoing social network that provide collective support for its members. The focus of this study is to explain how Athari Gauthi Ardi used Political Capital and Social Capital as a tool to win himself in political contestation in the 2019 legislative elections. Parental power used by Athari Gauthi Ardi to win the 2019 legislative elections in West Sumatra. Researchers' assumptions emerge that one of Athari Gauthi Ardi's capitals is political capital owned by his parents. The purpose of this study is to determine the political capital and social capital utilized by Athari Gauthi Ardi in the 2019 legislative elections and the relationship between political capital and social capital to Athari Gauthi Ardi's victory in the 2019 legislative general election. This study used study case qualitative methods. The results of this study indicate that Athari Gauthi Ardi has sufficient capital, such as : (1) Parent's network and Ali Mukhni's network are used by Athari Gauthi Ardi. (2) Political support obtained by Athari Gauthi Ardi from the community, religious and traditional leaders, the PAN Party, and regional cadres from the West Sumatra of PAN party. (3) Athari Gauthi Ardi was  intelligent woman with a tough personality, diligent and also can mingle with the community. (4) As well as sufficient economic capital owned by Athari Gauthi Ardi and his parents, who is a successful businessman.

This study aims to map the earthquake prone areas, and identify the nearest alternative route for evacuation of earthquake victims in Singkarak District, Solok Regency, West Sumatra. This research method was conducted with descriptive methods that analyzed by GIS (Geographic Information System) based on intensity scale (MMI). The results of this study stated that 90% of villages in Singkarak District had a high earthquake intensity, with an acceleration of the land surface of more than 0.34 g. For evacuation areas can be directed away from areas with steep cliffs and areas close to high buildings and should be directed in the direction close to Lake Singkarak, because the area around this has a low earthquake risk with earthquake acceleration of only 0.1 g.
