California today: making seismic security more intelligible

This week, like every four years, hundreds of earthquake experts gathered in Los Angeles in dimly lit rooms where complicated mathematical formulas representing things such as seismic energy and building resistance were projected on large screens.

For outsiders, these discussions can be almost incomprehensible. And some pundits who have gathered at the conference here this week say it’s symptomatic of a bigger problem: communicating with the public.

But big questions remain: How resilient are buildings in earthquake-prone areas? Should we build stronger ones?

A number of speakers and conference attendees urged engineers to better manage the mismatch between what the public often thinks the building code protects – and what it actually does.

“The problem is that the general public and building owners in particular really think that when they get a building up to code, they’ll get a building that will perform well in an earthquake,” said Mary Comerio, professor. at the University of California, Berkeley and a proponent of enhanced earthquake protection.

“The message to the public is that existing buildings are going to be damaged. It’s part of the calculations, ”Prof. Comerio said. “They are designed to help you exit the building, but you may not be able to return. “

A debate over the building code’s long-standing “life safety” philosophy – meaning it is designed to protect your life but not much more – was at the heart of the conference discussions. A bill in Sacramento that could potentially strengthen the code to a “functional recovery” standard is going through committees of the state legislature.

But proponents of more resilient buildings and infrastructure like water, gas lines, power grid and mobile phone systems say more can be done even within the existing code.

Maryann Phipps, a structural engineer who gave the keynote address to conference attendees on Thursday, urged engineers to explain to their clients that by spending an extra one or two percent, a building is more likely to be usable after an earthquake.

“My take-away point is that communication is important,” she said. “We have to keep it simple and clear. “

A quick tribute to our colleagues at The Capital Gazette in Annapolis, Md., Who lost five staff in Thursday’s shooting, but somehow made a resolution to release a Friday edition.

“Our newspaper is one of the oldest newspapers in the United States,” said Joshua McKerrow, a photographer for The Capital Gazette who was not in the office, picking up his daughter for her birthday at the time of the shooting. “It’s a real newspaper and like any newspaper, it’s a family.

“We will be here tomorrow,” McKerrow said through tears. “We’re not going anywhere.”
