Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Ground movements, such as settlement, landslides, and liquefaction, are often recorded during seismic events. A reliable approach to risk management involves the development of a preventive plan. This includes a cartographic map providing urban planners and engineers with the available techniques for reinforcing vulnerable soils that support important structures or are reserved for future urbanization. This indispensable document is currently attracting attention from researchers in Algeria, where the northern part is highly prone to seismic activity. Therefore, the aim of this study is to develop a map using Geographic Information System tools for managing risks associated with earthquake-induced ground movements in Chlef City (Algeria), a region renowned for its seismic activity and history of major earthquakes experienced during the last century. The methodology employed in creating the map draws on the findings of laboratory experiments and examines existing seismic micro-zoning study. Four soil reinforcement processes that are regularly used in seismic zones are implemented, namely densification, geotextiles, cement columns injection, and stone columns. Based on the experimental outcomes and the seismic hazard level, multiple reinforcement techniques are allocated to each area within the city perimeter, enabling local risk managers to select the most appropriate processes according to the local availability. In addition, the developed plan provides recommendations for additive measures that should be considered for more effectiveness. Thus, the developed map and the accompanying recommendations together constitute a useful preventive plan against induced ground movements in Chlef City. It also provides a technical guide for urban development planning and seismic risk management measures.
