To keep the loose soils beneath a planned hospital from liquefying and damaging the foundations during the design earthquake, Hayward Baker stabilized the site by performing wet soil mixing. In addition, HB installed tie down soil anchors inside soil mix columns to counterbalance the building seismic uplift forces. The team worked tirelessly to balance safety and production with stringent design and QC requirements. Learn more on their website, www.haywardbaker.com

New Study Shows Odds High for Big California Quakes
Released: 4/14/2008 12:02:15 PM
California has more than a 99% chance of having a magnitude 6.7 or larger earthquake within the next 30 years, according scientists using a new model to determine the probability of big quakes.
The likelihood of a major quake of magnitude 7.5 or greater in the next 30 years is 46%-and such a quake is most likely to occur in the southern half of the state.
[Editor] At Left: Figure 1. The colors on this California map represent the UCERF probabilities of having a nearby earthquake rupture (within 3 or 4 miles) of magnitude 6.7 or larger in the next 30 years. As shown in the table, the chance of having such an event somewhere in California exceeds 99%. The 30-year probability of an even more powerful quake of magnitude 7.5 or larger is about 46%.
