“…In [74], a GIS-based seismic risk assessment of a local district on the basis of data gathered from national census was performed, to assess the vulnerability of local populations, using a holistic model to estimate exposure, resilience, and capacity factors. GIS tools allow one to generate and display maps to highlight the socio-economic and physical characteristics of vulnerability for a district in Pahang, Malaysia.…”

The paper presents a methodology of extraction, integration and elaboration of data from different sources using the geographic information system (GIS), to realize a georeferenced building database (GBD) useful for the seismic vulnerability assessment of existing buildings on a large scale. Three levels of GIS entities have been defined and equipped with the related information: census section (CS), urban block (UB), and individual building (IB), depending on the level of detail of dataset. Additional information about the typological and structural features has been extracted by CARTIS catalogue, to refine the data associated with each building. The data have been validated using detailed information gathered on a proper sample of buildings, which have been filed and analyzed one-by-one. The alphanumeric format of data allows for the automatic implementation of different methods available in the literature, which provide a qualitative seismic vulnerability index at different scales (whole urban district, an urban block, and a single building). Finally, the 3D representation of data and results have been elaborated, providing a tool easily searchable and constantly implementable. An application has been developed for a case study in Puglia, Italy: Bisceglie, for which 3726 IB have been assessed. The work addresses the issue of the lack of information typical of large-scale applications, exploiting all the available data sources to achieve nearly complete knowledge of existing building stock finalized to a rapid but extensive evaluation of the seismic vulnerability on an urban scale with very low computational efforts and the use of limited resources in terms of time and cost.

“…As an example, in [24], authors proposed a methodology to create the seismic map identifying the building assessments and vulnerability. Moreover, a seismic risk evaluation method in a district level is proposed by [25]. The model assesses the seismic vulnerability using GIS for the definition of a vulnerability map.…”

Historical villages represent a highly vulnerable cultural heritage; their preservation can be ensured thanks to technological innovations in the field of geomatics and information systems. Among these, Geographical Information Systems (GISs) allow exploiting heterogeneous data for efficient vulnerability assessment, in terms of both time and usability. Geometric attributes, which currently are mainly inferred by visual inspections, can be extrapolated from data obtained by geomatic technologies. Furthermore, the integration with non-metric data ensures a more complete description of the post-seismic risk thematic mapping. In this paper, a high-performance information system for small urban realities, such as historical villages, is described, starting from the 3D survey obtained through the integrated management of recent innovative geomatic sensors, such as Unmanned Aerial Vehicles (UAVs), Terrestrial Laser Scanners (TLSs), and 360º images. The results show that the proposed strategy of the automatic extraction of the parameters from the GIS can be generalized to other case studies, thus representing a straightforward method to enhance the decision-making of public administrations. Moreover, this work confirms the importance of managing heterogeneous geospatial data to speed up the vulnerability assessment process. The final result, in fact, is an information system that can be used for every village where data have been acquired in a similar way. This information could be used in the field by means of a GIS app that allows updating the geospatial database, improving the work of technicians. This approach was validated in Gabbiano(Pieve Torina), a village in Central Italy affected by earthquakes in 2016 and 2017.

“…This event caused casualties of 18 people and damaged several government buildings such as Teachers Quarters, Hospital Quarters and school buildings. Lacking proper planning in earthquake disaster management will increase the risk of future fatalities, injuries and damages among Malaysian communities [3]. The 2015 Ranau Earthquake impact revealed this situation in Sabah.…”

A seismic event is unpredictable and may occur worldwide depending on the movement of the fault line. The impact of this phenomenon on society, structures, sources and surroundings is significant to be investigated. Thus, this study aims to investigate the seismic awareness level and input information among Malaysians. Several far-field seismic activities in Malaysia have triggered some high-rise buildings, including residential and commercial ones. Due to this situation, the occupants started to worry about their safety living in high-rise buildings designed without seismic considerations. The most important initial step is to investigate the awareness level among the occupants. A survey has been conducted in Georgetown, Pulau Pinang area involving 208 respondents. Findings indicate the respondents have limited experience with seismic events in Malaysia and were never exposed to seismic information. Less than 50% declared to have adequate knowledge about seismic. Only 31.25% of the respondents were exposed to the seismic information. Respondents agree that Malaysia should apply a seismic code of practice for all construction buildings. Most respondents believe that preparation for upcoming seismic activities is still insufficient, and all new buildings should have seismic safety certificates in the future for seismic resistance.
