  • California Today: Making Earthquake Safety More Intelligible (New York Times) This week, as they do every four years, hundreds of earthquake experts huddled in Los Angeles in dimly lit rooms where complicated mathematical formulas representing such things as seismic energy and building strength were projected onto large screens. To outsiders these discussions can be all but incomprehensible. And some experts who gathered at the conference here this week say that is symptomatic of a larger problem: communicating with the public. But big questions remain: How resilient are buildings in earthquake-prone areas? Should we build stronger ones? NYT writer Thomas Fuller interviews Mary Comerio (M.EERI,1988) and others at the 11NCEE. Read More
  • A Seismic Change in Predicting How Earthquakes Will Shake Tall Buildings (New York Times) A synopsis of research presented at the 11NCEE includes quotes from plenary speaker Norman Abrahamson (M.EERI,1984), conference co-chair Jim Malley (M.EERI,1990), SCEC director John Vidale, Ibbi Almufti (M.EERI,2011), C.B. Crouse (M.EERI,1976), and Thomas H. Heaton (M.EERI,1995). Read more 
  • New Simulations Break Down Potential Impact of a Major Quake by Building Location and Size (Phys.Org) With unprecedented resolution, scientists and engineers are simulating precisely how a large-magnitude earthquake along the Hayward Fault would affect different locations and buildings across the San Francisco Bay Area. A team of researchers lead by David McCallen (M.EERI,1990) are presenting three scientific papers describing their recent simulations at this week's 11NCEE. Read more

Student Leadership Council Spotlight

2018 EERI Undergraduate Seismic Design Competition! And the Winner is...

11NCEE MP11589Nearly 350 students participated in the 15th Annual EERI Undergraduate Seismic Design Competition (SDC) last week at the 11th National Conference on Earthquake Engineering (11NCEE) and 2018 EERI Annual Meeting in Los Angeles. Organized by the EERI Student Leadership Council (SLC), this was the largest SDC ever, with 40 teams representing 8 countries around the world, 16 U.S. States, and Puerto Rico.

The competition kicked off on Tuesday with preliminary judging of team presentations and posters. Wednesday was filled with excitement as teams put their structures to the test on the shaking table. "Shake Day" was live-streamed on Facebook receiving over 29,000 views and nearly 14,000 social media interactions, and broadcast throughout the day on a 360 degree digital display called a "Media Aquarium" that was located on the second floor of the Westin Bonaventure Hotel. On Thursday, the SDC students attended a Post-Earthquake Reconnaissance Workshop (PERW) and walking tour of downtown Los Angeles. Thursday evening, team members shed their competition tee shirts for fancy suits, dresses, and dancing shoes, and had a grand time at a Hollywood-style gala generously sponsored by CSI.

On Friday, the SLC and SDC student teams joined 11NCEE meeting attendees for the closing plenary session and SDC awards ceremony led by Masters of Ceremony, SLC Co-Presidents Daniela Martinez and Yolanda Lin. Michael Mahoney (M.EERI, 1996) of FEMA announced the winners.  First place was awarded to the team from the University of California, Berkeley ("Cal"). Second and third place went to the University of California, Los Angeles (UCLA) and Technical University of Cluj-Napoca, respectively. The latter travelled to the competition all the way from Romania. 

11NCEE MP19979Cal's winning performanceSeveral additional awards were presented during the ceremony. Pontificia Universidad Catolica Madre y Maestra (Dominican Republic) won both the Charles Richter Award for Spirit of the Competition sponsored by Kinemetrics, and Honorable Mention for Best Architecture. The University of British Columbia received both the Egor Popov Award for Structural Innovation sponsored by Degenkolb, and the CSI Best Communication Skills Award. In addition to winning first place, UC Berkeley also took home Honorable Mention for Seismic Performance. The winner of the tee shirt design competition was Technical University of Cluj-Napoca. Bryce Berrett of Brigham Young University won the Scavenger Hunt.

The EERI SLC wishes to thank the seven generous sponsors who made the 15th annual competition possible: the Federal Emergency Management Agency (FEMA), Computer and Structures, Inc.(CSI), Trimble, Inc., Degenkolb Engineers, Kinemetrics, California Earthquake Authority, and Oregon State University (OSU).
