Abstract

The global significance of Krakatau Volcanic Complex and Way Kambas National Park is the best potential areas to be developed as part of a world heritage, particularly as UNESCO Global Geopark. Both of these objects are in the Lampung Province, Indonesia. Soon, it is necessary to identify and make an inventory of key sites that could become the theme of the area. The study of geodiversity and scientific valuation was carried out which referred to the Technical Guidelines for the Assessment of Indonesia Geological Heritage Resources, 2019. Based on these studies and assessments, there are 14 key sites to represent for Geopark Krakatau-Way Kambas themes. These sites are closely related to the evolution of tectonic activity in the Southern Sumatera as well as the dynamics of magmatism and paleovolcanism that have occurred since the Mesozoic which has signification in human history as world heritage.

Abstract

The introduction of statistical pattern recognition becomes highly important for assessing disaster threats such as earthquakes. This approach is significantly more comprehensive and suitable for long-term event forecasting. Therefore, in the future, efforts can be promptly made to reduce the risk of disasters resulting from anomalies in lithospheric activity, especially frequent earthquakes in the Sumatra Island region, Indonesia. Statistical pattern analysis of lithospheric activity anomalies can be categorized through classification. Earthquake classification is performed based on magnitude scale and mathematical calculations of earthquake parameter unit conversion. The classification method employed in this research includes machine learning methods like k-nearest neighbor and support vector machine. The evaluation metrics used for machine learning models are model accuracy and confusion matrix tables.
