 PRESIDENT'S CORNER:
Hello SDAG Members,
We had a full house for our April meeting at Phil's BBQ, where three SDAG student
scholarship recipients - Nicolas Oliver, Emily Imperato, and Jordan Jaeger - did an
amazing job presenting their research! Well done! Thanks to everyone who was able to
attend — it was a memorable night!
Now how about that earthquake on May 14th?! I had just returned from the field and was
returning some equipment on the 4th floor when I started hearing odd creaking noises. It
took me a couple of seconds to realize - OH MY GOSH, it's an earthquake! A bit of panic
definitely set in, but I stayed put until the shaking (more like swaying, since the building is
on rollers) stopped, and then I made a beeline down the stairs and away from the
building. Phew! I haven't experienced many earthquakes of that magnitude... I'm originally
from the East Coast. It was pretty cool to experience - and fortunately, only minimal
damage was reported in the area. Hope everyone enjoyed the ride and wasn't rattled too
much.
While on the topic of earthquakes - the Annual SDAG Field Trip will be held this
September 26-28, where we'll explore the San Andreas Fault near the Wrightwood area! A
couple of weekends ago, Dr. Miles Kenney, Chuck Houser, and I had the amazing
opportunity to fly up to the field trip area and take some incredible aerial photos that will
be used for the guidebook cover and road log. What an experience that was! Shout out to
Chuck for piloting the flight! If you're interested in attending, registration is set to open at
the end of May 2025.
Next up is our May 14th meeting at Sufi Mediterranean Cuisine in Clairemont, which will
be our very first joint meeting with the Geo-Institute! Our speaker will be Dr. Sebastian
Lobo-Guerrero - a very experienced Geotechnical Project Manager and Laboratory
Manager at AGES Inc. in Pittsburgh, Pennsylvania - who will give a presentation on
landslide stabilization. Please sign up and pay by May 13th. Walk-ins are welcome, but
you'll need to pay with check or cash at the door.
Thanks, and see you all at the May 14th meeting!!

CALL FOR PAPERS
From Past President Jennifer Morton:
Hello Geo Community! I am currently working on my Master's degree at SDSU. Part of my thesis will include compiling a
geodatabase of investigations on the La Nacion fault system. If anyone has done any trenching or other work on the
fault and is willing and able to share the information I would greatly appreciate it! Thank you and Happy Holidays!
Publications
Based on the interest for the out of Print 1998 SDAG Book "Geology and Geothermal Resources of the Imperial and Mexicali Valleys" this book
is now available as a Google E-Book. Due to the age of this book, not having any electronic files, the need to update to color etc...
the decision was made to create an e-book from a scan of the book. The link to purchase this book is now live on the SDAG website
(Lowell Lindsay's 1998 Geothermal Book!).
Here is the link to the SDAG Publication web page https://www.sandiegogeologists.org/Publications.html and a screen shot below showing
this E-Book. Thanks for the donated book from the Lindsays, Dave Bloom for scanning the book and posting it on our Google E-Book site,
and Carolyn Glockhoff for adding the link to our SDAG Publication page - now this out of print book can now be purchased as an e-Book!

DID YOU KNOW THAT SDAG HAS A FACEBOOK PAGE?
Here is a link to the SDAG Facebook page: https://www.facebook.com/sandiegogeologists.org
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.
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.

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.

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.
