It is estimated that over 500,000 earthquakes occur globally each year, with about 100,000 being felt and around 100 causing some level of damage. According to National Geographic, the disposal of wastewater from hydraulic fracturing (fracking) may be increasing seismic risks, particularly in regions like the U.S. Southwest and Midwest, where fault lines are not fully mapped. Fortunately, both businesses and individuals can take steps to protect their properties. Whether the cause is tectonic movement, volcanic activity, or fracking, preparing for potential disasters is essential. By retrofitting buildings now, we can significantly reduce future losses and ensure safer communities.
Oklahoma has become a hotspot for seismic activity in the U.S., surpassing even California in the number of earthquakes recorded annually. Once experiencing just one earthquake per year above magnitude 3.0, Oklahoma now sees one every day. The rise in seismic events has led many to suspect hydraulic fracturing as the main cause. Fracking involves drilling deep into the earth and injecting high-pressure fluids to release natural gas trapped in shale formations. While it produces large quantities of energy, concerns remain about water contamination, radiation exposure, and induced earthquakes. Although scientific consensus is still developing, studies show that fluid injection can trigger small quakes. However, correlation does not always mean causation, and other factors such as tectonic shifts and natural oil deposits may also play a role.
Earthquakes are no longer a question of if, but when. To minimize damage and save lives, proactive measures are crucial. In San Francisco, officials are pushing for mandatory seismic retrofits for vulnerable buildings. A voluntary program has seen limited participation, but new legislation could require thousands of property owners to upgrade their structures. Retrofitting soft-story buildings—those with open ground floors—can prevent major destruction during a quake. While the cost is significant, the long-term savings from avoiding catastrophic damage make it a wise investment.
Carbon fiber has emerged as a key material in seismic retrofitting due to its strength and lightweight properties. A manufacturing facility in the southwestern U.S. used HJ3's CivilTM hybrid carbon fiber system to reinforce three concrete walls. The project involved applying high-modulus paste and over 30,000 square feet of carbon fabric, which improved structural integrity while cutting costs by 40% compared to traditional methods. The installation was completed in three weeks, saving time and resources. Additionally, the project avoided 625 tons of waste and reduced environmental impact by conserving water, energy, and reducing CO2 emissions. If your building needs seismic upgrades, consider innovative solutions like carbon fiber for a sustainable and effective approach. Contact HJ3 for more information.
