Seismic vulnerability assessment of buildings in high-risk areas: A modified rapid visual screening approach in Pakistan

14/08/2025 TranSpread

In Dir City, Pakistan, the majority of structures are non-engineered and old, and were built by local masons. Based on the Building Code of Pakistan, the city falls within Seismic Zone III, and these could be vulnerable during a seismic event.

In a study (DOI:10.1016/j.jdd.2025.100018 ) published in Journal of Dynamic Disasters, a hundred randomly selected buildings, including residential, commercial, government, and religious buildings, were assessed in a (rapid visual screening) RVS survey via a modified Federal Emergency Management Agency (FEMA) data collection form.

“The structural configuration of the surveyed buildings was diverse—unreinforced masonry, confined masonry, stone masonry, and reinforced concrete (RC) frames with unreinforced masonry (URM) infill,” shares first author Khan Shahzada.

The authors used positive and negative score modifiers to assign and modify basic scores based on characteristics that increase or decrease seismic resistance in a building; low final scores indicate the need for further expert examination. The final scores were then mapped to damage grades representing potential vulnerability. Drawing on the findings, suggestions for improving the earthquake resilience of Dir City are offered.

Based on the Building Code of Pakistan, falls within Seismic Zone III.

“We recommend several actions to mitigate seismic risk and improve the seismic resilience of the buildings in Dir City,” says Khan. “These recommendations focus on enforcing stricter regulations, retrofitting vulnerable structures, and fostering community engagement to build a culture of preparedness.”

According to the authors, the following steps should be prioritized:

•Ensure that all new buildings, especially those located on slopes, adhere to engineering design standards to reduce seismic vulnerability.

•Prioritize retrofitting of older, non-engineered buildings, especially residential structures with a relatively high risk of severe seismic damage.

•Implement regular inspections to verify compliance with seismic safety standards and to identify necessary repairs.

•Educate residents on the importance of seismic resilience and encourage them to take steps to improve the seismic safety of their homes.

•Offer grants or low-interest loans to building owners to encourage investment in retrofitting and structural improvements.

•Create comprehensive plans that include early warning systems, earthquake drills, and the strengthening of critical infrastructure such as hospitals and schools.

•Residents should actively seek professional seismic evaluations of their buildings, invest in retrofitting, and ensure that new buildings comply with seismic resistance standards.

•Residents should acquire emergency kits, create family emergency plans, and facilitate and organize community discussions about seismic risks to build a culture of preparedness.

•Researchers should expand on Level 1 screenings by conducting highly in-depth studies on retrofitting methods, material performance, and slope stability.

•Perform studies assessing the impact of retrofitting measures and explore modern technologies such as seismic isolation systems to enhance the seismic resilience of buildings.

•Involve local stakeholders in applying research findings and improving the seismic safety of Dir City’s infrastructure.

About Journal of Dynamic Disasters

The Journal of Dynamic Disasters is one journal dedicated to publishing authoritative articles on dynamic disasters. Topics of interest include earthquake, wind, wave, explosion, shock, vehicle and environmental vibrations. The journal features original research and case studies focusing on the dynamical analysis, disaster mechanisms, disaster prevention, disaster monitoring, disaster assessment and post-disaster restoration for engineering structures (such as civil engineering structures, mechanical engineering structures, aerospace structures, marine structures). The journal welcomes interdisciplinary studies, covering topics such as sensing, signal processing, intelligent management and control of dynamic disasters.

Testimonials

For well over a decade, in my capacity as a researcher, broadcaster, and producer, I have relied heavily on Alphagalileo.
All of my work trips have been planned around stories that I've found on this site.
The under embargo section allows us to plan ahead and the news releases enable us to find key experts.
Going through the tailored daily updates is the best way to start the day. It's such a critical service for me and many of my colleagues.
Koula Bouloukos, Senior manager, Editorial & Production Underknown
We have used AlphaGalileo since its foundation but frankly we need it more than ever now to ensure our research news is heard across Europe, Asia and North America. As one of the UK’s leading research universities we want to continue to work with other outstanding researchers in Europe. AlphaGalileo helps us to continue to bring our research story to them and the rest of the world.
Peter Dunn, Director of Press and Media Relations at the University of Warwick
AlphaGalileo has helped us more than double our reach at SciDev.Net. The service has enabled our journalists around the world to reach the mainstream media with articles about the impact of science on people in low- and middle-income countries, leading to big increases in the number of SciDev.Net articles that have been republished.
