SDAG Events / Announcements

PRESIDENT'S CORNER:

Hello SDAG Members,

I hope this newsletter finds you all happy happy. We are back for the final two meetings of the year and this one should be a good'n. Eldon Gath will be speaking this month on the large landslide in the Southern Highlands of Papua New Guinea that was devastating for the area. He will go over the case study and its results concerning assessment of causation. For all of us landslide fans (no pun intended), it should be a lot of fun.

SDAG will be looking to fill the Vice President position next year. If there is a brave soul among you that would be willing to step into that position and follow up as President the next year, please send an email to myself or Mariana with your response. As VP, your responsibilities would mainly be focused on theannual field trip and accompanying guidebook. Someone with a trip already in mind would be best,however we have a great group of people that are available to help support the VP if not.

Don't forget our annual meeting at the Natural History Museum with Tom Demere on December 14th .Save the date!

And, as always, don't forget to fill out and send in your membership forms (and sponsorship forms, too)!

Cheers!

-Luke Weidman,
2022 SDAG President


SAVE THE DATE - Noon-1:00pm Friday December 2nd

PRELIMINARY ANNOUNCEMENT: A (VERY) SHORT COURSE ON THE IDENTIFICATION OF PALEOLANDSLIDES
A very short course on the identification of Paleolandslides will be presented for an hour by Mike Hart at noon on Friday December 2nd, 2022. The course is intended for engineering geologists wanting to improve their landslide identification skills. The course will take you through a landslide time warp beginning with how a slide looks at infancy through old age and the last topographic evidence of existence. Although intended primarily for professional geologists with no or little experience with landslide investigations it should also be of interest to geotechnical engineers wanting to gain an understanding of how geologists identify landslides by their diagnostic landforms. A take-home mapping exercise to gauge their new landslide identification skills will be available on request.

Short Course Cost: There will be no cost to attend. Although a donation of $40 is highly suggested to help fund the annual SDAG Student Scholarships. Any donation amount can be paid by mailing a check or using the following PayPal link which also allows Debit or Credit Cards. If paying by check, make payable to "San Diego Geological Society, Inc." a 501(c)3 public benefit nonprofit educational corporation and mail the check to: San Diego Geological Society, Inc., 3130 North Evergreen Street, San Diego, CA 92110.

If paying by PayPal, click on the yellow "Donate" button on the SDGS web page

Short Course Time & Zoom Link:
Dec 2, 2022 12:00 PM Pacific Time (US and Canada).
The course will be one hour presented via Zoom. The Zoom time is scheduled from noon to 1:30pm to accommodate any questions or discussion after the one-hour course.

A brief Bio:

Mike is a Certified Engineering Geologist and has practiced in the southern California area for over 50 years. Mike is a graduate of San Diego State University (M.S.1972, Landslides of West-Central San Diego County, California). Since leaving Geocon 1992 he has been an independent engineering geology consultant. His interest in landsliding began during undergraduate studies at SDSU; an interest that ultimately led to a career-long, slightly irrational, fascination with landslides. Mike has been involved with numerous landslide investigations and has published extensively on landsliding in southern California.

NEW Interactive Fault Map for San Diego

As part of the update for the San DiegoTijuana Earthquake Planning Scenario, Working Group No. 1's "Fault Map Subcommittee" completed the first publicly available bi-national active and potentially active fault map (http://sandiego.eeri.org/?page_id=265). This interactive GIS map includes the first publicly available active and potentially fault map locations from the City of San Diego. The map also integrated the faults south of the border for a bi-national cross border view. This map is an on-going project as our knowledge increases about local active and potentially active faults.

You can expand the map legend on the left side to select layers that can be turned on or off for the map view. You can also select from 1 of 12 base maps at the base map icon. You can click on the fault line in your map layer view to see the meta-data source. In addition, the City of San Diego Seismic Safety Study Geologic Hazards & Faults Maps are available in the layer titled "GeoHaz SD City." Please note that the City "Zone 12 Potentially Active" fault layers was not included in this data, therefore you will need to use the City Maps to find Zone 12.

The Fault Map 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 (dianemurbach@gmail.com 619-865-4333), Chair for the SDTJ 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 dbarrie@sdccd.edu with queries or samples.

ROCK DONATIONS NEEDED: Amy Romano, one of our former student members, is looking for rock donations. Amy is currently attending Humboldt State University and majoring in Geology. She is very involved with Humboldt's Geology Club, and every year the club holds a rock auction to support their activities. If you have any rocks to donate, please contact Amy at ajr612@humboldt.edu.

Annual Scholarship Awards by the San Diego Association of Geologists, a program of the San Diego Geological Society, Inc.

A primary function of the San Diego Association of Geologists (SDAG) is to support academic opportunities in geology and related sciences. By-laws of the San Diego Geological Society (SDGS) specify the support of academic opportunity ranging from elementary through graduate levels. The SDAG scholarship program has supported academic research in higher education by awarding scholarships annually to students from two-year and four-year undergraduate and master's level programs. Awards are for outstanding research in geology and related sciences. Nominations are solicited from individual faculty and from geology or related science departments at accredited academic institutions. Evaluation of the relative merit of each nominee is based on an abstract describing the objectives and results of the research being conducted by the student and on the letter of recommendation by the student's mentor or nominating committee.

The annual timeline is as follows:
  • Request for nominations occurs in September.
  • Nomination letters and research abstracts are received by the Scholarship Coordinator in mid to late October.
  • Awardees and their nominators are invited to attend the December SDAG dinner meeting. Scholarship awards are distributed to the student during the December meeting.
  • Students accepting awards are required to give a presentation of their research results usually at a spring dinner meeting of SDAG.
For further information contact SDGS Board at http://www.sandiegogeologicalsociety.org/contact.html through the Contact Us option

SDAG RESEARCH TOOL

A comprehensive listing of all papers published by SDAG, whether as annual field trip guidebooks or special publications, is available on our website. Entries are sorted by primary author, or chronologically by date of publication, from our first guidebook in 1972, up the San Luis Rey River in 2013, from Coast to Cactus in 2014, and finally over the edge to the Coyote Mountains in 2015. These can be accessed or downloaded as .pdf files. They are fully searchable in Adobe Reader or Acrobat, so if you are researching a topic, "tsunami" for example, you can search for that keyword. This listing will be updated as new books are published. Thanks to Greg Peterson and Hargis + Associates, Inc., for making this possible. See the links below:

SDGS/SDAG

As many of you are aware, the San Diego Geological Society (SDGS) was formed in early 2010 as an official non-profit 501(c)3 corporation, and SDAG is now an organization under this corporation. The reasons for doing this were many and they are spelled out in an informational sheet, the Business Plan of SDGS. The officers of SDGS should be very familiar to you, as they are all past presidents of SDAG. For those of you that would like to read more about SDGS and what it means to SDAG, check out the informational page on the website. Also check out the website www.sandiegogeologicalsociety.org.
