Scientists warn that California faces a significant risk from rare but powerful 'supershear' earthquakes that move faster than seismic waves, potentially causing more widespread and intense shaking. They emphasize the need for updated building standards, enhanced monitoring, and advanced simulations to better prepare for these destructive events, which could occur multiple times in the coming decades.
The article highlights significant progress in reducing deadly city fires in the US over the past decades, thanks to improvements like smoke alarms, automatic sprinklers, safer furnishings, and stricter building codes, despite ongoing risks especially in older buildings and from wildfires.
A rare 4.8 magnitude earthquake struck the Northeast, prompting officials to assess infrastructure for damage. Experts emphasize the need for preparedness and planning for potential future disasters, as earthquakes are not as prioritized on the East Coast compared to more seismically active areas. While New York City and other urban areas have adopted seismic building standards, codes vary across jurisdictions. Despite the minimal impact of the recent quake, experts warn that the East Coast is not immune to larger earthquakes, and older buildings in cities like New York may be vulnerable to seismic shaking.
Taiwan's preparedness for earthquakes stems from its regular exposure to seismic activity, with a history of devastating quakes prompting revisions to building codes and disaster management laws. The country's well-practiced rescue teams and coordinated response efforts, including mock alert messages and designated disaster drills, have contributed to effective disaster preparedness. Despite concerns about developers cutting corners, Taiwan's response to the recent 7.2 magnitude earthquake in Hualien showcased its resilience, with minimal impact on communication networks and swift mobilization of rescue teams. Additionally, Taiwan's disaster response capabilities have garnered international recognition, with the U.S. ambassador praising the country's successful model of disaster prevention and humanitarian rescue efforts.
Investigators are focusing on construction flaws in the pool deck as the cause of the 2021 collapse of the Champlain Towers South condominium in Surfside, Florida, which resulted in 98 deaths. The National Institute of Standards and Technology (NIST) has found that the concrete used in the pool deck and supporting columns was weaker than required by building codes, and the added weight from planters contributed to increased stress. While the collapse likely initiated in the pool deck, NIST has not ruled out a failure initiation in some part of the tower structure. The investigation is examining at least 40 potential failure hypotheses and aims to complete its technical work by summer, with a draft report and recommendations expected in May 2025.
The recent heavy rainfall and landslides in Hong Kong's upscale Redhill Peninsula have highlighted the vulnerability of even the most expensive and well-constructed homes to the effects of climate change. The storm, which brought the heaviest rainfall in nearly 140 years, prompted an evacuation of three millionaire homes that were perilously close to the cliff's edge. Experts warn that extreme weather events will become more frequent, affecting both the rich and the poor. Investigations are underway to determine if building code violations contributed to the problem, raising concerns about the unequal enforcement of rules. Architects and civil engineers are calling for a review of safety standards for hillside buildings, while authorities suspect illegal alterations may have worsened the disaster.
Hurricane Idalia caused heavy damage to homes in the fishing village of Horseshoe Beach, Florida, but some residences built on stilts remained relatively unscathed. State building codes, regularly revised to withstand catastrophic weather events, played a significant role in protecting these homes. However, the debate arises between building stronger structures and considering income disparities and the preservation of local culture. The aftermath of Idalia highlights the need for improvements in building codes and the challenges faced by homeowners in raising older residences. Grants may be available for rebuilding, but stricter building codes and insurance requirements may apply. The storm may serve as a turning point in reevaluating how communities rebuild and adapt to climate change.
Elon Musk's decision to place a large glowing 'X' logo above Twitter's headquarters in San Francisco has sparked a conflict between the billionaire and the city's administration. The structure, which lights up in a blinking pattern, prompted complaints from neighbors and an investigation by the Department of Building Inspection. This clash is the latest in an ongoing feud between Musk and San Francisco officials, with previous disputes over alleged safety and building code violations.
As climate change leads to more extreme weather events, architects and builders are exploring resilient home designs to better protect against disasters. Geodesic domes, steel structures, and houses made from concrete are gaining attention for their ability to withstand high winds, wildfires, and storms. However, the higher costs associated with these resilient designs pose a challenge, as most home buyers are unaware of the benefits and reluctant to pay extra. Tightening building codes could help bridge this gap, but many areas lack up-to-date standards. Despite the challenges, there is growing interest in disaster-proof homes as people become more climate-conscious and seek sustainable and durable housing solutions.
The Biden administration is set to award $90 million in grants to help cities, states, tribes, and organizations implement stronger building codes to make structures more energy-efficient and resilient to extreme weather events. The funding, distributed by the Energy Department, aims to address the increasing frequency of weather disasters fueled by climate change. The grants will support 27 projects in 26 states and the District of Columbia, with a focus on implementing modernized energy codes that can save households on utility bills. While the federal government cannot mandate building codes, the administration hopes to encourage states and municipalities to adopt updated codes through financial incentives. The United States' buildings are responsible for about 35% of the nation's carbon emissions, and updated building energy codes are projected to reduce carbon emissions by 900 million metric tons from 2010 to 2040.
Federal investigators looking into the Surfside, Florida, condo collapse that killed 98 people in 2021 said the structure did not meet building codes when it was erected 42 years ago. National Institute of Standards and Technology (NIST) project leader James Harris said there were errors in construction and renovations that compounded those deficiencies. NIST is placing a particular emphasis on the pool deck, with pervasive concerns with the deck's design and misplaced slab reinforcement. NIST’s investigation will not be finished until May 2024 at the earliest. The final report could take an additional year.
The National Institute of Standards and Technology (NIST) has released preliminary findings on the partial collapse of the Champlain Towers South building in Surfside, Florida, which killed 98 people in 2021. NIST's investigation is focusing on the failure of the building's pool deck, which was constructed improperly and didn't meet building codes. The team found problems in the way the concrete was cast, leaving it permeable to water and corroding much of its steel reinforcement. The NIST team's leading hypothesis is that the collapse began when the pool deck failed due to punching shear failure. The final report is expected in two years.
Federal investigators have found that the pool deck of the Champlain Towers South condo in Surfside, Florida, which collapsed in June 2021, had a "severe strength deficiency" and failed to meet building codes and design parameters. The preliminary analysis suggests that the pool deck's failure could have triggered the collapse of the 13-story tower, which killed 98 people. Investigators have been conducting a complex inquiry into the cause of the collapse, including examining the original design and construction of the building, renovations and repairs, corrosion, ground settlement, and vibrations from nearby construction. The final report is not expected until May 2025.
San Francisco officials are investigating Twitter after six former employees allege that owner Elon Musk’s leadership team broke laws in turning the company’s headquarters into a “Twitter Hotel” for workers being pushed to stay up late to transform the social media platform. The ex-employees also allege that Musk’s team ordered numerous changes to the company’s headquarters in a 1930s Art Deco building in downtown San Francisco that violated building codes. This is the latest investigation into Twitter, which Elon Musk took over late last year.
San Francisco officials are investigating Twitter's headquarters after a lawsuit from six former employees alleged that members of owner Elon Musk's team knowingly broke local and federal laws. The suit claims that Twitter didn't pay promised severance and that Musk's team instructed staff to disable lights and install locks that wouldn't open during an emergency at employee bedrooms, violating building codes. The plaintiffs are seeking severance, punitive damages for "flagrant bad faith," alleged fraud, and alleged violation of local and federal laws.
