“…The Community-Based Bathymetric Survey (CBBS) data used in this study comprise fishing boat track records from GPS sounders with data logging devices. The data include the date, time, depth, sea surface temperature (SST), boat speed, heading, and geographical position (Haridhi et al, 2016;Rizal et al, 2013). Data were collected from 45 local fishing boats in the northern Sumatra area, which had installed sounder equipment due to participation in a project supported by the Asian Development Bank (ADB) as an effort to rehabilitate the traditional fishing community after the mega earthquake and tsunami disaster on December 26, 2004 (Wilson and Linkie, 2012).…”

Abstract. Near the northern border of Sumatra, the right-lateral strike-slip Sumatran Fault Zone splits into two branches and extends into the offshore, as revealed by seismic sounding surveys. However, due to its strike-slip faulting characteristics, the Sumatran Fault Zone’s activity is rarely believed to cause tsunami hazards in this region. According to two reprocessed reflection seismic profiles, the extended Sumatran Fault Zone is strongly associated with chaotic facies, indicating that large submarine landslides have been triggered. Coastal steep slopes and new subsurface characteristics of submarine landslide deposits were mapped using recently acquired high-resolution shallow bathymetry data. Slope stability analysis revealed some targets with steep morphology to be close to failure. In an extreme case, an earthquake of Mw 7 or more occurred, and the strong ground shaking triggered a submarine landslide off the northern shore of Sumatra. Based on a simulation of tsunami wave propagation in shallow water, the results of this study indicate a potential tsunami hazard from a submarine landslide triggered by the strike-slip fault system. The landslide tsunami hazard assessment and early warning systems in this study area can be improved on the basis of this proposed scenario.

“…The southwest monsoon (SWM) occurs between June and September, while the northeast monsoon (NEM) takes place between December and February [3]. It is known that monsoon winds influence ocean circulation [4,5]. Several studies have been conducted in the MS, such as simulations of currents and tides [1,6,7].…”

This study analyzes the sea currents, temperature, and salinity in the Malacca Strait during the northeast (NE) and southwest (SW) monsoons of 2022, represented by monthly average data from the Copernicus Marine Service (CMEMS) data portal for January and July, respectively. Vertical sections are created to visualize the layer structure and variations of sea parameters within the water column. The findings reveal differences in sea currents, temperature, and salinity between the NE and SW monsoons. July (SW monsoon) records consistently warmer temperatures than January (NE monsoon), both at the sea surface and seabed. Surface salinity is higher in July than in January, while seabed salinity is greater in January than in July. In January, the salinity-influenced mixed layer depth (MLD) appears to be thicker than the temperature-influenced MLD. There are no significant differences in the thickness of the temperature- and salinity-influenced MLDs during July. These variations in sea currents, temperature, and salinity at different depths provide a comprehensive understanding of the marine environmental structure and dynamics of the Malacca Strait.
