“…The resulting tsunami heights along the south coast of western Java from Scenario 1 and 2 show that a maximum tsunami height of up to ~ 8 m is likely to occur in the region with an average of 1.8 m for Scenario 1 and 3.3 m for Scenario 2. In comparison, a tsunami height of up to ~ 20 m with an average of 4.5 m was estimated using slip de cit determined from GPS data (Widiyantoro et al 2020). Thus, our estimated tsunami height is less than half that of the previous study that assumes the same earthquake magnitude.…”

“…Great earthquakes close to the Java trench are typically interplate faulting events along the slab interface between the Australia and Sunda plates; these earthquakes generally have high tsunamigenic potential due to their shallow depths (Jones et al 2014). The absence of recent great earthquakes may indicate that even more powerful tsunamigenic events along the south coast of western Java are a potential threat (Widiyantoro et al 2020). The regions along the southern coast of western Java, e.g., Pelabuhan Ratu, Pangandaran, and south of Banten (Fig.…”

“…In this study, we investigate the potential for megathrust earthquakes and consequent tsunamis south of western Java through relocation of earthquake data from April 2009 to July 2020. We also conduct tsunami simulations using megathrust sources provided by the Indonesian National Center for Earthquake Studies (PuSGeN; Irsyam et al 2020) and compare our results with the interplate coupling sources from GPS data inversions undertaken in previous studies (Hanifa et al 2014, Widiyantoro et al 2020. Two different rupture scenarios are tested, with a focus on maximum wave height along the south coast of West Java.…”

High seismicity rates in and around West Java occur as a result of the Indo-Australian plate converging with and subducting beneath the Sunda plate. Large megathrust events associated with this process likely pose a major earthquake and tsunami hazard to the surrounding community, but further effort is required to help understand both the likelihood and frequency of such events. With this in mind, we exploit catalog and phase data sourced from the Agency for Meteorology, Climatology, and Geophysics (BMKG) of Indonesia and the International Seismological Centre (ISC) for the period of April 2009 through July 2020, in order to conduct earthquake hypocenter relocation using a teleseismic double-difference method. Our results reveal a seismic gap to the south of West Java, which is in agreement with a previous GPS study that finds the same region to be a potential future source of megathrust earthquakes. Tsunami modeling was conducted in the region based on two scenarios using sources from the Indonesian National Center for Earthquake Studies, and show that the maximum tsunami height may be up to ~ 8 m. This estimate is approximately half the maximum tsunami height predicted by a previous study in which earthquake sources were derived from GPS data inversion.

Significant earthquakes frequently occur in Indonesia. Indonesia is situated over three active tectonic plates, resulting in the formation of faults and trenches on the land and ocean floor. For the last 120 years since 1900, there have been more than 1,250 significant earthquake events in Indonesia. In this study, we analyse Indonesia's significant earthquake events using geostatistical and geovisualisation methods to produce an appropriate geospatial analysis platform using the RShiny package to build the WebGIS application. The results show that the earthquake events were spatially distributed from the Sumatera fault in the western part of Indonesia to the southern part of Indonesia, where the Java trench was located and the eastern part of Indonesia. The WebGIS application received a positive evaluation by respondents, with a mean value of 1.617 for pragmatic quality, 1.808 for hedonic quality, and 1.713 for overall quality. This means that the WebGIS application is of good quality based on respondents' impressions. The users also more easily gained insight into information as a result of geostatistical methods. The information gained by the users during the user interaction with the WebGIS platform overlapped with the information that the researcher started with, that is, the spatial cluster of significant earthquakes in Indonesia.

Background Precision medicine, space exploration, drug discovery to characterization of dark chemical space of habitats and organisms, metabolomics takes a centre stage in providing answers to diverse biological, biomedical, and environmental questions. With technological advances in mass-spectrometry and spectroscopy platforms that aid in generation of information rich datasets that are complex big-data, data analytics tend to co-evolve to match the pace of analytical instrumentation. Software tools, resources, databases, and solutions help in harnessing the concealed information in the generated data for eventual translational success. Aim of the review In this review, ~ 85 metabolomics software resources, packages, tools, databases, and other utilities that appeared in 2020 are introduced to the research community. Key scientific concepts of review In Table 1 the computational dependencies and downloadable links of the tools are provided, and the resources are categorized based on their utility. The review aims to keep the community of metabolomics researchers updated with all the resources developed in 2020 at a collated avenue, in line with efforts form 2015 onwards to help them find these at one place for further referencing and use.
