“…In another study but with no direct relation to educational aspects, we examined vulnerability to earthquake hazards in the Java northern regions [60] that poses increasing danger to local community in the northern coasts of Java. In addition to persistent threats from the active subduction zone located off the Java south coasts [1][2][3]11,12] potential earthquake sources from shallow crustal seismicity in the northern regions of Java induced by inland fault activity have been in search [61][62][63][64][65][66][67]. The primary goal of this study was to assess vulnerability in the presence of seemingly connecting crustal faults along the northern regions.…”

“…Thus, the Indonesian highly complex, volcano-tectonic setting comprises convergent plate boundaries, extending from off the west coasts of the north Sumatera to the Banda Arc in the eastern provinces, making both ground-based and coastal regions in Indonesia vulnerable to geological disasters that include tectonic earthquakes, tsunamis and volcanic eruptions. While the primary cause for tsunami generation and its corresponding propagation is attributable to earthquake of tectonic origin for global observations [5], in the Indonesian context, however, previous studies on possible tsunami sources also pointed out volcanic processes [6,7] and landslides [8][9][10] as potential sources of such a disaster, in addition to seismic sources [11,12].…”

Earth Physics Research Group (EPRG) is one of three groups of research running at Physics Study Program, the State University of Surabaya, Indonesia, where a number of research projects with corresponding topics have been conducted (and some are in progress) by the group members and associated students having final projects in the field of earth physics since 2018. Whereas the research roadmap of the group has been presented in association with definitive research projects for 25 years long starting from 2011, the specific goal of this paper is to shortly summarise all academic achievement in terms of research performance made by the group members during the last five years. The majority of the recent works was mainly based on computational work, where some were completed in collaboration with researchers from other universities and a national agency and others were performed by the group members and selected students. The topics were spread across disciplines in earth physics that included tectonic earthquakes, tsunami generation and propagation of seismic and non-seismic origin, volcanic eruptions and an integrated disaster mitigation study. A small portion of the projects were performed using a chosen method of applied geophysics. These studies have ended up with publications in recent years, where the saline points of the key findings are here presented. Future studies focusing on vulnerability to earthquake hazards in the northern areas of Java and on volcanic and meteo-tsunamis are also discussed in the context of possible tsunamis induced by seismic sources or volcanic processes.

“…Research conducted by Supendi et al (2023) shows a seismic gap to the south of the island of Java that has a potential source of future megathrust earthquakes. This potential earthquake could generate tsunami heights of up to 20 meters on the south coast of West Java, with an average maximum height of 4.5 meters along the south coast of Java.…”

“…Other research shows that there is still a high tsunami potential due to the megathrust fault in southern Java, which has an earthquake return period of 500 years (Harris et al, 2019). This condition is reinforced by the fact that no major earthquakes have occurred in the past few years; only medium-sized earthquakes (Mw<8) have occurred in the past 100 years (Supendi et al, 2023). This means that megathrust earthquakes still have the potential to occur.…”

Abstract. Indonesia's location in the middle of tectonic plates makes it vulnerable to earthquakes and tsunamis, especially in the megathrust zone around Sumatra Island and the southern part of Java Island. Research shows a seismic gap in southern Java, which poses a potential threat of megathrust earthquakes and tsunamis, impacting coastal areas such as Batukaras Village in West Java, a popular tourist destination. To prepare for disasters, Probabilistic Tsunami Hazard Analysis (PTHA), which focuses on seismic factors, was carried out by modeling tsunamis on 3,348 sub-segments of 4 large megathrust segments in the south of Java Island. Stochastic earthquake modeling to simulate the occurrence of a tsunami from an earthquake with 6.5 Mw to the highest potential magnitude on each segment. This research shows that PTHA in Batukaras Village reveals varying heights of 0.84 m, 1.63 m, 2.97 m, and 5.7 m for each earthquake return period of 250 years, 500 years, 1000 years, and 2500 years. The dominant threat arises from the West Java-Central Java megathrust segment, emphasizing the importance of preparedness, although the annual probability of tsunamis is generally low. Our study will deepen knowledge of tsunami hazards associated with megathrust activities near Batukaras Village for mitigation planning and decision-making, and it can become a reference for similar coastal tourist areas.
