Generally, you won't see much damage from earthquakes that register below 4 on the Richter scale. Richter ratings only give you a rough idea of the actual impact of an earthquake, though. As we've seen, an earthquake's destructive power varies depending on the composition of the ground in an area and the design and placement of man-made structures. There are countless ways of minimizing the impact of earthquakes, such as securing furniture and building structures that meet current standards for earthquake-prone areas. During an earthquake, people should not move around or try to get o...Most earthquakes occur along the boundaries between the Earth’s tectonic plates. The crust of the Earth is divided into plates. When a plate collides with or slides past another plate, this causes earthquakes.REDi™ rating system [1] to provide owners, architects and engineers with a framework for implementing “resilience-based earthquake design”, a holistic design, planning, and verificationRating systems for Earthquake, Wind (2022), Flood (forthcoming) and Wildfire (forthcoming) Sponsorship of legislation that will protect up to 200,000 Californians The Resilience Advantage Webinar Series viewed by more than 8,500 attendees
