seismic waves

June 2019 Newsletter.

Ali Sahabi A recent magnitude 8 earthquake in Peru caused little damage, while another several years ago killed hundreds and damaged tens of thousands of structures. Why is it that quakes of the same magnitude can be so different? Scientific American explains below that it is all about location. We also know that earthquake damage is determined by soil conditions, the type of wave movement, and the vulnerability of the structure hit by that land movement. If you live or work in a vulnerable building that has survived quakes in the past, remember that a different set of circumstances may bring about entirely different results. Contact us today for a free consultation to learn more about your retrofit needs and how to best protect your assets.

Politics, Attitudes About Risk Influence Structural Codes

Politics, Attitudes About Risk Influence Structural Codes

We have the know-how to build structures that can survive even a major earthquake. Whether that happens is very much a matter of politics and cultural attitudes about risk, the New York Times reported.

Study: Small Quake May Signal Future Disaster

Study: Small Quake May Signal Future Disaster

Scientists say a small earthquake near Newport-Inglewood/Rose Canyon fault may be the harbinger of a 6.8 to 7.5 magnitude quake, more powerful than what was experienced there in 1933, the L.A. Times reported.

Why Do Buildings Fail In An Earthquake?

There’s a saying in our industry, that earthquakes don’t kill people. Buildings do. Yes, it is over-simplified, but the fact remains that earthquake threats to public safety are fundamentally linked to structural stability.

SoCal Riddled with Tiny Quakes. Is Big One Coming?

Hundreds of earthquakes hit Southern California recently, the majority not felt because they were so small. It has been five years since the region experienced a quake of 6.0 or larger, the Los Angeles Times reported. Is this a sign we should be worried?
