Greetings SDAG members!
March was a busy meeting, setting the record for the longest SDAG meeting...at least to my knowledge! My thanks to all of the students who presented, and in particular, congratulations to Luke Weidman who has since successfully defended his Master's thesis and become a full-time employee of Geocon. My thanks also to Laurie Racca from the State Board who provided us with the late night update on professional licensing requirements. The turnout for the March meeting was once again excellent with almost 70 people in attendance. One thing I would like to remind people of is to please sign in with our treasurer, Adam Avakian, when you arrive and grab a name tag as well. For this meeting, we had seven people who slipped in unnoticed by us, but not by the restaurant owner. As we assume that everyone who attends will pay, it makes it very hard to budget meetings when we have to account for the few that don't.
Moving on, we are back at Marina Village this month with John Minch, longtime member/supporter of SDAG and pivotal contributor to last year's field trip, who is going to present on the 1995 Kobe earthquake and its effects on high rise buildings and infrastructure. The Walawender Tavern with be in full swing, kindly staffed by Cari Gomes (SDAG President, 2013), so please come and join us once again for good food, beer and wine, and what will most certainly be, another excellent presentation.
In other news, if you haven't heard of AB-199, please take the time to do a little research on it. It is California's latest, altruistic effort to expand the definition and scope of a prevailing wage project. As with all California Bills, the language is confusing and suitably ambiguous, so as to divide public opinion and confuse the general populous. However, there are certainly those who feel it will have a negative effect on the California housing market and private development, and therefore, a potentially negative effect on those of us with livelihoods related to construction of residential homes...certainly food for thought.
As always, please feel free to contact me at firstname.lastname@example.org if you have questions, suggestions etc. regarding all matters SDAG related. Please don't forget to check out the details on the latest upcoming OSW to the San Ysidro landslide complex, led by Mike Hart and Sue Tanges.
I look forward to seeing everyone again on the 19th at Marina Village!

2017 SDAG President
OSW - Tuesday April 25th at 1:00 pm
Matt Love and Rupert Adams with Geocon, Inc. have set up a One Stop Wonder for a Stone Column job in the
Midway Area. A great chance to see some Geotechnical Engineering at work!
*PLEASE NOTE* This stop will require FULL PPE (hard hats, safety glasses,
safety vests, and safety boots). I'm sorry if you do not have these but
since it is an active construction site, we must follow the rules set by
the contractor onsite.
The site is located at the corner of Kemper Street and Kenyon Street south
of Midway Drive in the Midway District. There is no onsite parking so you
will need to find street parking.

ONE STOP WONDER - The San Ysidro Landslide and La Nacion Fault
Led by: Mike Hart & Sue Tanges
Saturday April 22, 2017
The meeting point will be at the east end of Beyer Blvd in San Ysidro.
* Take San Ysidro Blvd offramp on 805 South.
* At the stoplight turn left onto San Ysidro Blvd and then turn left on
Central Street just past the bridge over 805.
* Turn Left onto E. Beyer Blvd and go north about 1/2 mile to Beyer Blvd. Turn right and go to the end of the street.
* Park on both sides of the street.
What Will We See?
1. A great exposure of the La Nacion Fault where it juxtaposes the Otay and San Diego Formations.
2. The primary slip surface at the left flank of the approximately 3/4 mile wide San Ysidro landslide where it lies in contact with genty dipping beds of the Otay Formation.
3. Lanslide breccia and shear zones exposed in a roadcut.
4. Panoramic views of the Moody Canyon landslide complex and classic landslide geomorphology including grabens, back-tilted mesa surfaces and ponded drainage.
The trip will take approximately 2 hours and will involved hiking up a moderately steep dirt road so bring water, hat, etc.
This a dog friendly area so bring them if you like.
Contact Mike Hart at firstname.lastname@example.org if you have any questions.

In the News
As a result of heavy rainfall, the Mocoa River overtopped its banks, sending water, trees, and rocks through the city of Mocoa. So far, there are 254 confirmed fatalities, with many more missing.
As part of the update for the San Diego-Tijuana Earthquake Planning Scenario, Working Group No. 1's "Fault Map Subcommittee" has completed the first publicly available bi-national active and potentially active fault map. This interactive GIS map includes the first publicly available active and potentially active fault map locations from the City of San Diego. The City of San Diego fault locations and activity of faults are based chiefly on interpretation of information contained in geologic reports by private consultants. The City of San Diego identifies active faults as Holocene (<= 11,000yr) and potentially active as Quaternary (up to 1.6my). City of San Diego fault investigations are ongoing that may require future revision of this map. This map is not a substitute for a site specific fault investigation. The map also includes an updated fault map layer from the State CGS. CGS suggests users defer to the City of San Diego fault data, where marked, for increased accuracy. The map also integrated the faults south of the border for a bi-national cross border view. You can expand the map legend on the left side to see the fault ages and sources for each layer that can be turned on or off for the map view. You can select from 1 of 12 base maps. You can click on the fault line on the map to see the meta-data source. This map includes the yellow dashed SURFACE FAULT RUPTURE location layer that will be used for the infrastructure, social, and economic impacts and emergency response for the update to the Earthquake Scenario. In addition, active and potentially active fault investigation locations from private companies are planned to be added to this map as a resource. This map is an on-going project and resource as our knowledge increases about local active and potentially active faults.
The link is available at: http://www.sandiegogeologists.org/Faults_map.html
I would like to thank Carolyn Glockhoff for her endless GIS work, Jim Quinn and the City for providing their data and time, Jerry Treiman with CGS for his time preparing the Surface Rupture and providing their new State fault data layer, and Luis Mendoza at CICESE for providing the faults south of the border. Please contact Diane Murbach (email@example.com), Chair for the SD-TJ Earthquake Scenario Working Group #1 - Earth Science, if you have any questions, or see any errors on this new fault map.

Got too many rocks?
Are you (or specifically, your spouse...) interested in giving them a good home *away* from your house and garden?
Mesa College is looking to collect some rock samples for an inaugural Earth History course.
We are specifically looking for sedimentary rocks that include examples of different energy environments (varying grain sizes and shapes) and structures (ripples, cross bedding, planar bedding, graded bedding, etc.).
We are also looking to beef up our fossil collection and are looking for all the major phyla: Echinoderms, brachiopods, mollusks (bivalves, cephalopods, gastropods), arthropods (trilobites and more!), corals (Cnidaria), Porifera, Bryozoa, vertebrates (Chordata), etc.
Looking for both actual standalone specimens or in the rock still (showing different environments of deposition).
We are looking for fossil preservation examples, and also for good trace fossil evidence.
Got any sediment grain samples from cool locales? We'll take them! If you have anything else you think provides a good 'story' in the rock, we are willing to check it out!
We are collecting ASAP to assess how much needs to be ordered for the fall course.
Please contact Jill Krezoski at JillKski@hotmail.com or Don Barrie at email@example.com with queries or samples.

Kenji Ishihara lifetime achievement award to be presented at EERI meeting March 30, 2017
Prof. Kenji Ishihara was born in Chiba, Japan in 1934. He started his studies in Civil Engineering at the University of Tokyo, obtaining BS-degree in 1957, MS-degree in 1959, and Ph.D-degree in 1963. During one-year period from 1966 to 1967, he was a Visiting Research Associate at the University of Illinois in Urbana, U.S.A. under the guidance of late Professor R. B. Peck. He has been affiliated with the University of Tokyo since then, taking the position of professorship in geotechnical engineering since 1977. On his retirement from the University of Tokyo in 1995 he took up the position of Professor of Geotechnical Engineering at the Tokyo University of Science and then at Chuo University in 2001.
He served for ISSMFE as secretary of the Japanese National Committee for the period of 7 years between 1970 and 1976 during which time he attended the Executive Committee meeting of ISSMFE in Sydney, 1971 as a voting member representing the Japanese National Society. Since then, he often represented Japan in several Executive Committee Meetings of ISSMFE and those of Asian region. He acted as Vice-President of Asian region of ISSMFE during the period of 1989-1993.
His major research interest covers problems in soil dynamics associated with earthquakes, such as liquefaction of sandy deposits, and seismic stability of slopes and earth structures. He wrote about 250 papers on these subjects.
He has served on various occasions as consultant or adviser to UNESCO projects (Balkan region, India) and UNDP project (Chile, India, Iran). He has participated in the geotechnical investigations of earthquakes worldwide such as those in Romania (1977), Yugoslavia (1979), Chile (1985), Mexico (1985), Ecuador (1986), Soviet Armenia (1988), Soviet Tajik (1989), Philippines (1991) and Iran (1991). He is the author of the book "Fundamentals of Soil Dynamics" (1974) and the textbook "Soil Mechanics" (1988) both in Japanese. He recently published from Oxford Press an English book entitled "Soil Behaviour in Earthquake Geotechnics".
He has received the honor by being assigned on many occasions to deliver lectures worldwide including the theme lecture in the 11th ICSMFE in San Francisco and the 33rd Rankine Lecture of the British Geotechnical Society in 1993. He acted as chairman of the Technical Committee TC4 on Earthquake Geotechnical Engineering in ISSMFE for the two tenures of office from 1985 to 1993. His incessant endeavor in TC4 has led to the periodical holding of the International Conference on Earthquake Geotechnical Engineering of which the first in a series was held in Tokyo in 1995 and the second in Lisbon in 1999. He has also received honor by being awarded the H. B. Seed Gold Medal in 1998 from the American Society of Civil Engineers. For his significant contribution, title of Honorary Doctorate was given to him from Technical University of Bucharest, Romania in 1995 and from Istanbul Technical University, Turkey in 1999. In 2000, he was honored by being bestowed the most prestigious Japan Academy Prize. In 2010, he was elected to Foreign Associate of the United States Academy of Engineering.
In commemoration of his long-time contribution to the profession, the International Conference on Earthquake Geotechnical Engineering held in Istanbul by the efforts of Professors A. Ansal and M. Sakr, published two volumes of selected papers containing major publications by Prof. Kenji Ishihara.
