Ali Sahabi South Korea, an area previously considered immune from earthquakes due to its location far from tectonic plates, suffered $53 million in damage in November from its second-largest quake in modern history. Scientists have just come out with the finding that the magnitude 5.5 quake was sparked by a geothermal plant built shortly before the earthquake struck. Did the injection of many thousands of cubic meters of water into the earth in 2016 and 2017 cause the quake? That question is still open for debate. What is proven is that in regions like California — where fault lines are as prevalent as interstate freeways — earthquakes are a daily reality. Most are small, nearly undetectable. But scientists agree “The Big One” is building its force under the ground, waiting to strike. There is no debate about that. Is your building going to remain standing when it does?

Non-ductile Buildings Among List of Vulnerable Structures

California’s skyscrapers look invincible, but many constructed with non-ductile concrete prior to the 1990s can be vulnerable to damage and/or collapse in a major earthquake. Limited lateral resisting capacity makes these structures brittle and susceptible to damage during seismic activity.
