Peta Sumber dan Bahaya Gempa Indonesia Tahun 2024

by tektonesiana

Disusun Oleh:Pusat Studi Gempa Nasional (PuSGeN) EXECUTIVE SUMMARY Peta Sumber dan Bahaya Gempa Indonesia (Peta Gempa Indonesia) merupakan acuan nasional yang sangat penting dalam penetapan beban gempa untuk kebutuhan perencanaan pembangunan yang aman terhadap gempa. Sejak peluncuran Peta Gempa Indonesia 2017, telah terjadi sejumlah gempa besar seperti Gempa Lombok (2018), Palu (2018), Halmahera (2019), Ambon … Continue reading Peta Sumber dan Bahaya Gempa Indonesia Tahun 2024

Hybrid turbidite–contourite systems in the modern Tarakan Basin: seismic sedimentology and analogue for subsurface storage (Nugraha & Maulin, 2025)

by tektonesiana

Hybrid turbidite–contourite systems are present where gravity-driven and bottom-current processes interact. Although recent studies have advanced our understanding, deciphering the relative roles of downslope and alongslope processes in shaping the deep seafloor remains an important subject of investigation. The Tarakan Basin, offshore northeastern Borneo, is a prolific hydrocarbon province, yet its modern sedimentary systems are … Continue reading Hybrid turbidite–contourite systems in the modern Tarakan Basin: seismic sedimentology and analogue for subsurface storage (Nugraha & Maulin, 2025)

Seismic velocity structure beneath the western Java region, Indonesia, from local earthquake tomography

by tektonesiana

Journal of Volcanology and Geothermal Research https://doi.org/10.1016/j.jvolgeores.2025.108472 The western Java region is situated along the Sunda Arc, which is formed by subduction of the Indo-Australian Plate beneath the Eurasian Plate. The subduction process causes seismic activity in the Wadati-Benioff zone of the descending slab, produces a chain of active volcanoes, and forms numerous faults in … Continue reading Seismic velocity structure beneath the western Java region, Indonesia, from local earthquake tomography
