What it means for you

Which fits you?

Pick the situation closest to yours. Each answer says what it rests on.

If you are deciding where to spend a limited school-safety budget

prioritised retrofitting of masonry school buildings is the measure with the clearest modelled cost–benefit case, based on Romania's analysis of about 15,000 buildings.2

Evidence-backed

If your schools are in a seismic zone and were built before modern codes

Cyprus's approach — assessing all school buildings, retrofitting them, and adding monitoring — is a worked national example, though its outcome data are not reported here.6

Evidence-backed

If you want a building to remain usable after an earthquake, not just survive it

treat seismic resilience as an explicit decision criterion; it can change which retrofit option is preferred, especially when valued as an annualised expected value.7

Evidence-backed

If you are designing or reviewing a masonry school in a seismic area

regular architectural and structural design and a multi-fortification system are recommended, and raising the seismic fortification level is suggested.5

Evidence-backed

If you are auditing why a school collapsed or is at risk

check the as-built structure and materials against code demands, as the Van investigation did, and check for substandard materials and code violations, as the Indian forensic case found.34

Evidence-backed

If you are assessing safety and only looking at the main structure

include roofs and other non-structural elements; a roof collapse in Pakistan killed at least 33 pupils and a teacher.1

The full explanation

Interpretation AI-prepared starting map

School buildings collapse mainly when earthquakes or other loads exceed what their structure can carry, and the damage is concentrated in unreinforced masonry and poorly detailed load-bearing systems. Investigations of collapses in Turkey, China, India and Pakistan point to the same cluster of causes: buildings designed or built without adequate seismic provisions, substandard materials, code violations, and the absence of a multi-fortification (defence-in-depth) system. On the safety side, the strongest evidence comes from seismic retrofitting programmes: Romania's national assessment of about 15,000 school masonry buildings estimated losses of almost €240 million and 2,500 potential casualties in a 50-year hazard scenario, and showed that prioritised retrofitting substantially reduces those expected losses. Cyprus retrofitted all its school buildings after three earthquakes in the 1990s, and Italy has studied how to combine seismic and energy retrofits while tracking post-earthquake operability.1234567

01

How school buildings collapse

AI summary:Investigations in India, Turkey, China and Pakistan trace collapses to substandard materials, code violations, missing seismic provisions, and even roof failure alone.

Evidence-backed

Evidence-backed: A forensic investigation of a collapsed elementary school in India that killed 5 children and injured many others identified the cause and led to a conviction in court. The study links collapses to substandard building materials, corruption, and construction operating with inadequate or violated building codes, with municipal authorities approving schools, colleges and apartments under those conditions.4

Evidence-backed

Evidence-backed: A school building in Van, Turkey, collapsed in the 23 October 2011 Tabanli earthquake (Mw 7.2). Using as-built drawings and specified material properties, researchers built a numerical model and ran pushover analyses against Turkish Seismic Code demands to determine member-by-member and overall damage levels, in order to establish the actual cause of the collapse.3

Evidence-backed

Evidence-backed: After the 12 May 2008 Wenchuan earthquake, on-site investigation of school masonry buildings distinguished damage to the principal structure, destruction of local parts, and damage to non-structural elements. Principal-structure damage fell into three levels: total collapse, heavy damage without collapse, and moderate damage. The main reasons for the differences were the local seismic intensity, whether the building was designed and constructed to meet seismic fortification requirements, and whether it had a multi-fortification system.5

Evidence-backed

Evidence-backed: In Pakistan, a school roof collapsed and crashed through three classrooms, burying children under the debris; at least 33 pupils and a teacher were killed, according to police. This is a non-structural or roof-failure event rather than a full structural collapse, and it shows that the roof and other non-structural elements are part of the safety picture.1

02

What makes school buildings safer

AI summary:Romania's cost-benefit work, Cyprus's nationwide retrofit, and an Italian study show retrofitting cuts losses, though surviving is not the same as staying usable.

Evidence-backed

Evidence-backed: Romania assessed a broad database of school masonry buildings under two seismic hazard scenarios. For an earthquake with a 63% exceedance probability in 50 years, estimated losses for the education sector's masonry structures reached almost €240 million and 2,500 potential casualties. Cost–benefit analysis across about 15,000 buildings, with prioritisation criteria, showed that investing in retrofitting these structures leads to significant reductions in potential losses, and the results were mapped as annual failure probabilities nationwide to support public policy.2

Evidence-backed

Evidence-backed: Cyprus decided to seismically retrofit all its school buildings after earthquakes in 1995, 1996 and 1999, explicitly because of the social sensitivity of structures housing the next generation. The programme has run for over 10 years, includes an assessment methodology and a wireless monitoring system, and compares mathematical models of selected schools with in-situ measurements.6

Evidence-backed

Evidence-backed: For school masonry buildings, the Wenchuan investigation recommends regular architectural and structural design and a multi-fortification system, and suggests raising the seismic fortification level.5

Evidence-backed

Evidence-backed: An Italian study of an existing reinforced concrete school retrofitted under four distinct strategies found that satisfactory seismic behaviour does not guarantee the building stays operational after an earthquake. It reviews methods for quantifying seismic resilience, incorporates resilience as a decision variable alongside seismic and energy retrofitting, and uses multi-criteria decision-making across social, technical, environmental and resilience criteria. Resilience changes which combined seismic-and-energy strategy is preferred, especially when treated as an annualised expected value.7

Before you go

What to remember

Try to recall each hidden figure before you reveal it. Remembering, not rereading, is what makes it stick.

  1. Romania's national assessment estimated almost € million in losses and 2,500 potential casualties for school masonry buildings in a 50-year hazard scenario, and found that prioritised retrofitting significantly reduces expected losses.

  2. School collapses cluster around a few causes: earthquakes exceeding capacity, buildings designed or built without seismic provisions, substandard materials, code violations, and no multi-fortification system.

  3. Cyprus retrofitted all its school buildings after three earthquakes in the 1990s, combining assessment, monitoring and model validation over more than a decade.

    Seismic risk reduction through retrofitting of school masonry buildings from Romania
    Frontiers in Built Environment (Scupin & Văcăreanu)Published Jan 9, 2023Checked Oct 15, 2026
    “Starting from a broad database of school masonry buildings, potential losses were evaluated considering two seismic hazard scenarios. For an earthquake having a 63% exceedance probability in 50 years, losses estimated for the education sector comprising masonry structures reached almost 240 mil. € and 2,500 potential casualties. For highlighting that investments in retrofitting masonry structures from the education sector lead to significant reductions of potential losses, prioritization criteria were proposed and cost–benefit analysis was carried out for about 15,000 buildings. Results are presented through graphs and maps that illustrate the distribution of annual failure probabilities at the national level. Therefore, the methodology proposed and the results presented in this paper can represent a valuable tool for substantiating public policies aiming at reducing the seismic risk, in particular for existing masonry structures.”

    Earthquake performance of collapsed school building under Van-Tabanli (Mw=7.2) earthquake
    Challenge Journal of Structural Mechanics (Coşgun & Mangır)Published Dec 5, 2018Checked Oct 15, 2026
    “At the end of 2011, numerous ground motions of various intensities have been registered in city of Van in eastern Turkey starting from 23 October 2011. Two major earthquakes were experienced at the Tabanli and Edremit district of Van. The moment magnitudes of these earthquakes were announced as 7.2 and 5.6, respectively. The investigated school building in this study was located in the city of Van and collapsed after first major earthquake (Mw=7.2). Structural details of the load-bearing members of the investigated building including as-built drawings and specified material properties were obtained. Based on obtained data, a numerical model was created to simulate the behavior of the building under code specified earthquake effects. Earthquake performance assessment of the structure was carried based on the recommendations given in the related chapter of the Turkish Seismic Code. Pushover analyses were performed and expected member by member damage levels and overall structural damage were determined in accordance with Turkish Seismic Code. The results are discussed to enlighten the actual cause of the collapse.”

    Investigation and analysis for damage of school masonry buildings in Wenchuan earthquake
    Dalian Ligong Daxue xuebao (Li-cheng)Published Jan 1, 2009Checked Oct 15, 2026
    “In terms of the results of in-site investigation of Wenchuan earthquake which occurred on 12 May,2008,the seismic damage of school masonry structural buildings is presented and summarized.The damage of masonry structures is basically clarified as damage of the principal structure,destruction of some local parts of a building as well as the damage of non-structural elements.Additionally,as the damage degree of the principal structure is concerned,it is further divided into 3 levels of damage,i.e.,collapse of the total structure,heavy damage but not collapse and the moderate damage.The major causes resulting in different damage degrees of the masonry structures are commonly attributed to the following reasons: different seismic intensity where the structure exists;whether the building is designed or constructed to meet the requirements of seismic fortification;and whether the building has a multi-fortification system.Finally,for the school masonry buildings,it is suggested to take some measures,such as the regular architecture and structure design,multi-fortification system,to devate the seismic fortification level.”

    Seismic Retrofitting and Health Monitoring of School Buildings of Cyprus
    The Open Construction and Building Technology Journal (Chrysostomou et al.)Published Dec 27, 2013Checked Oct 15, 2026
    “The vulnerability of existing buildings to seismic forces and their retrofitting is an international problem. The majority of structures in seismic-prone areas worldwide are structures that have been designed either without the consideration of seismic forces, or with previous codes of practice specifying lower levels of seismic forces. In Cyprus, after the three earthquakes that occurred in 1995, 1996, and 1999, the Cyprus State, acting in a pioneering way internationally, has decided the seismic retrofitting of all school buildings, taking into account the sensitivity of the society towards these structures, which house the future generation of the society. In this paper the overall assessment methodology is presented, along with details of the over 10 year ongoing retrofitting program of the school buildings of Cyprus, with emphasis on the description of the program and the development of a wireless monitoring system. In addition, mathematical models of selected school buildings are presented and comparison is made with in-situ measurement.”

    Seismic Resilience Assessment in Optimally Integrated Retrofitting of Existing School Buildings in Italy
    Buildings (Carofilis et al.)Published Jun 16, 2022Checked Oct 15, 2026
    “Seismically retrofitted buildings behave satisfactorily under expected earthquake scenarios; however, this does not guarantee operativity after a seismic event. This study critically reviews several methods currently available in the literature that quantify the seismic resilience level of buildings from different perspectives. An existing reinforced concrete school building, retrofitted according to four distinct strategies, is first evaluated in terms of seismic resilience levels. The overview and critical analysis of available resilience assessment frameworks determine the most suitable parameters to measure the seismic resilience for buildings. Subsequently, this metric is incorporated as an additional decision variable into an integrated seismic and energy retrofitting set of strategies. A multicriteria decision-making analysis is performed to select the optimally combined seismic and energy retrofitting alternative under social, technical, environmental evaluation, and seismic resilience aspects. We show how resilience impacts the preference for integrated seismic and energy retrofitting strategies, especially when this metric is considered as an annualized expected value.”
