Observations from the EERI Bridge Team
The Bridge Team has spent the last two days in the epicentral region. What a contrast to skirting around the edge of strong shaking on Monday! We spent most of Tuesday traveling to the now remote town of Tubul. Remote “now” because a landslide and bridge collapse has cut off the town except for a […]

Observations from the EERI Bridge Team
The Bridge Team made it back to Santiago today after covering over 1200 miles in the last 4 days. We realized that of all of the teams, we have the most ground to cover. Partly because bridges are dispersed around the entire region, and partly because many of our sites to investigate are dead end […]

Soil Liquefaction Observations
About 5 hours after the earthquake I went down to the shore of the Villarrica Lake Temuco, and observed a very strange phenomena. Some googling showed that a possible explanation is soil liquefaction. This was later confirmed by Lisa Wald from USGS who recommended posting on this website. On some places at the beach, which is essentially […]

Initial Impressions from EERI Team Leader
There is also considerable damage to URM buildings which are historic structures. At a public meeting at City Hall, the mayor, and council (and the director of a newly opened recovery center–one stop shop for permits and advice) took questions from a packed audience. There is real concern about the loss of the historic fabric […]
Safety Assessment Efforts in Canterbury
New Zealand’s safety assessment protocols for buildings are similar to those in the U.S. for placing red (unsafe), yellow (restricted access) or green (inspected) placards on buildings so we were somewhat familiar and generally helpful in documentation of the placarding and in making decisions. Responsibility for each team’s decisions were principally delegated to Certified Professional Engineers from other […]
