The terms resiliency and sustainability, although similar in meaning, refer to different design approaches in the context of architecture and cities. Sustainability involves the preservation of natural resources to uphold ecological equilibrium, while resiliency entails the ability to rebound, adapt, and persist in moments of adversity. These concepts greatly influence and complement each other, especially in cases of designing disaster-resilient buildings. Conventional design processes relating to resilient infrastructure have been based on principles of structural robustness and integrity as a measure against anticipated natural disasters. However, sustainable resiliency points at the opportunity of reinforcing buildings by embedding them in biological and ecological systems.
The Türkiye Design Council (TDC) has gathered 13 design practices, including Foster + Partners and Bjarke Ingels Group, to contribute to the revitalization of the historic province of Hatay, an area severely damaged by the 7.8 magnitude earthquake in February this year. Foster + Partners has been selected to lead the design and planning of the new master plan for the city of Antakya, known to antiquity as Antioch, while several other offices including Turkish practices DB Architects and KEYM (Urban Renewal Center) will work together to create a vision for the rebuilding of the city. The master plan is expected to be revealed in its entirety in 2024.
As the world grapples with the effects of climate change, natural disasters like flooding, and the spread of incontrollable wildfires are increasingly threatening cities and inhabitants. While architecture and urban planning cannot prevent these occurrences, they still possess strategies to minimize the damage associated with these events and help protect the citizens. Unfortunate events over the course of last year, like the earthquake that hit central Turkey and north-west Syria this February or the more recent earthquake in western Afghanistan, the flooding and dam failures in Libya, and the wildfires that devastated the city of Lahaina, Hawaii, demonstrate the urgency of implementing preventative and mitigation measures in addition to creating procedures for emergency intervention. This article explores the strategies and resources available to architects and urban planners to address these challenges in three types of natural disasters: flooding, wildfires, and earthquakes.
Friday, September 8th, a 6.8-magnitude earthquake hit Morocco’s High Atlas Mountain range. The epicenter was located just 72 kilometers southwest of Marrakech, the country’s fourth-largest city and a popular tourist destination. The quake is the strongest to hit the nation’s center in more than a century. Estimates put the number of victims at over 2,000 and more injured, but as several towns and villages remain inaccessible high in the mountains, the number is expected to increase. In addition to the human toll, several historical landmarks, including UNESCO World Heritage sites, have been affected, while eyewitnesses in the foothills of the mountains report that several remote towns have been completely destroyed, according to CNN.
When it comes to seismic resistance, there are a number of myths that question the ability of wood to adequately perform in the event of an earthquake. However, its ductility allows it to deform plastically without breaking, absorbing and dissipating the energy generated by movement and vibration. Furthermore, unlike steel or concrete, wood is a lightweight material with a good strength-to-weight ratio, enabling it to withstand seismic forces without adding excessive load to the construction. This has been extensively verified in smaller-scale structures around the world, but how does a high-rise mass timber building behave in the face of an earthquake?
To dispel doubts, the Tallwood Project recently erected a 10-story building made of cross-laminated timber (CLT) at the University of California, San Diego (UCSD). The structure was tested on a shake table that simulated the 1994 Northridge earthquake in Los Angeles, magnitude 6.7, and the 1999 Chi-Chi earthquake in Taiwan, magnitude 7.7.
Shigeru Ban Architects, in collaboration with Voluntary Architects’ Network, has developed an improved version of the temporary housing developed to help those affected by the recent Turkey-Syria earthquake. The new prototype represents an upgrade of the paper tube system deployed in northwestern Turkey after the 1999 earthquake. This new version takes into consideration matters of efficiency and the need to minimize construction time on site.
A major 7.8 magnitude earthquake hit central Turkey and north-west Syria this Monday, February 6, with a second 7.4 magnitude quake reported a few hours later in the same region, according to reports from the Guardian. Among the most affected areas is Gaziantep, located 150 miles from the border with Syria and 50 miles from the earthquake’s epicenter in Kahramanmaraş. Tremors were felt as far away as Lebanon, Greece, Israel, and the island of Cyprus. Authorities are still assessing the number of victims, as local and international rescue teams have been deployed to search for survivors. Early estimates report that over 1,700 buildings have collapsed or have been critically damaged, as confirmed by Turkey's Vice President Fuat Oktay.
‘’We’re in a seismic area. Beirut has been buried seven times, so it has to resist any earthquake, and that’s why it also resisted the explosion in the port,’’ expresses Lina Ghotmeh in conversation with Louisiana Channel, in regards to the Stone Garden. A building constructed with resilience in mind, in a city that has been buried within rubble and rebuilt multiple times.
Lina Ghotmeh was interviewed by Marc-Christoph Wagner at her studio in Paris in November 2021. Renowned for her Humanist approach to Architecture, the Stone Garden offers a very personal relationship as the first building to be constructed in Ghotmeh’s hometown of Beirut. Positioned on the edge of the city center, it is very much a form of vernacular architecture echoing the lives of the people who reside here.

Haiti is suffering the consequences of a magnitude-7.2 earthquake that worsen a national crisis. News agencies have published photographs of collapsed buildings in Port-au-Prince recalling the destruction due to the 2010 earthquake.
As humanitarian aid is been deployed around the world to collaborate in rescue, shelter, health care, and food, questions arise: how does architecture help?
Ten years after a destructive earthquake rocked Italy's central Abruzzo region, many students still attend class in temporary modules similar to containers. Named winners of an international competition, SET Architects’ design for the new “Sassa School Complex” proposes reconstructing a place for students and the community to learn, gather, and grow. Inspired by the modularity and essential nature of climbing frame play structures, the architects describe the design as a metaphor for “freedom and social aggregation as a fundamental value for dynamic and innovative teaching.”
Schmidt Hammer Lassen Architects and Architectus have announced the opening of Tūranga, the new central library for Christchurch, New Zealand. Built to address the earthquakes that damaged Christchurch in 2010 and 2011, the library is one of the first public buildings to open downtown after the disasters. Working with Architectus and the indigenous Māori people of New Zealand’s South Island, the design was made to celebrate rebirth in Christchurch.
For 181 Fremont, Arup’s radical move was to do away with plans for a tuned mass damper or a sloshing damper on the skyscraper’s roof—common features in tall towers in the U.S. for reducing the natural sway of buildings. Neither damper style goes very far in protecting a building against seismic force, says Ibbi Almufti of Arup. Image Courtesy of Kevin Chu/KCJP
The most remarkable thing about 181 Fremont—San Francisco’s third-tallest tower, designed by Heller Manus Architects—is not the penthouse’s asking price ($42 million). Rather, it’s an innovative yet unglamorous structural detail: a viscous damper system that far exceeds California Code earthquake-performance objectives for buildings of 181 Fremont’s class, allowing immediate reoccupation after a seismic event.
You wouldn’t think it looking at Mexico City today—a densely populated metropolis, where empty space is hard to come by—but decades earlier, following a devastating earthquake on September 19, 1985, more than 400 buildings collapsed, leaving a collection of open wounds spread over the cityscape.
Exactly thirty-two years later, the anniversary of that disaster was ominously commemorated with an emergency evacuation drill. Then, in one of those odd occurrences in which reality proves to be stranger than fiction, a sudden jolt scarcely two hours after the drill led to what would be yet another of the deadliest earthquakes in the city’s history. Buildings once again collapsed, leaving a rising-by-the-hour death toll that eventually reached 361, as well as swarms of bewildered citizens wandering the streets, frantically attempting to reach their loved ones through the weakened cell phone reception. “We’d just evacuated for the drill,” people said, like a collective mantra. “How could this happen again?”
In August 2016, a powerful 6.2-magnitude earthquake struck central Italy, resulting in the loss of nearly 300 lives and the destruction of centuries-worth of historic architecture. At the center of the destruction was Amatrice, a beautiful hill town set in the Latium Apennines, which was reduced to mere rubble, leaving hundreds dead or injured and the survivors homeless.
Researchers from the university of British Columbia have developed a new fiber-reinforced concrete treatment that can “dramatically [enhance] the earthquake resistance of seismically vulnerable [structures].”
Called EDCC (eco-friendly ductile cementitious composite), the material is engineered at the molecular level to react similarly to steel – with high strength, ductility and malleability. When sprayed onto the surface of traditionally poured interior concrete walls, it reinforces against seismic intensities as high as the magnitude 9.0-9.1 earthquake that hit Tohoku, Japan in 2011.

Following the devastating earthquake measuring 7.1 in magnitude that struck Mexico yesterday at 13:14 local time, many—over 200 people at the time of writing—are feared either dead or trapped in collapsed buildings or unsafe structures. While rescue efforts continue and information surrounding the scope of devastation is preliminary, schools are closed indefinitely and major companies and organizations have requested their employees not to work.
The death toll continues to rise while ArchDaily México, which is located in Mexico City, reports wide-reaching destruction of the built fabric of the capital. Footage captured by terrified residents show the final moments of buildings—many taller than four stories—that were reduced to dust and debris in seconds.
