That’s the result of this week’s second round of levee earthquake tests out on Sherman Island, according to the lead researcher.
Scott Brandenberg, vice chair of undergrad studies with UCLA’s Department of Civil and Environmental Engineering, summed it up this way in an email this morning:
“The test sequence was similar to last year, except that we saturated the peat beneath the model levee this time. As a result, it appears that the response was different and we measured a bit more settlement. There were no other immediate conclusions, and the scientific conclusions related to levee-peat interaction will require some time to develop.”
Engineer Bob Pyke, who attended the tests on Wednesday, had previously reported that there was “some damage” to the embankment but “no visible penetration into the peat.”
Update: Here’s a Bay Area television station’s report on Wednesday’s test.
