Major Revision to California Guide for Assessing Fault Rupture Hazards (SP 42)

​​​​​​​​​​​​​​​​​CGS released a major revision to its Special Publication 42 (SP 42): Earthquake Fault Zones – A Guide for Government Agencies, Property Owners / Developers, and Geoscience Practitioners for Assessing Fault Rupture Hazards in California.  SP 42 has been the primary guidance document since 1975 for providing background regarding the Alquist-Priolo Earthquake Fault Zoning Act (AP Act) and the assessment of surface fault rupture hazard.  The 2018 edition is the latest update to this document, with a focus on providing more detailed guidance to government agencies, property owners, and geoscientists who are affected by the AP Act.  This edition is freely available on the CGS website as a pdf download.​ Read more

2/23/18 – RAY TABER FOUNDATION Presents its Annual, FREE “Drill Seminar” – Volunteers, Sponsors, and Attendees NEEDED


WHEN:        FEBRUARY 23, 2018, 9AM – 4PM


WHAT:    The Ray Taber Foundation, a non-profit with the sole mission of providing scholarships to encourage and support students, is hosting its annual free Drilling Exploration Seminar at Taber Ranch in the beautiful Capay Valley.  This educational event is a field seminar for graduate and undergraduate civil engineering and geology students.  It is often called a “day of opportunity”, providing the future leaders of our industry with a unique forum for asking questions, getting answers and having a “hands on” experience with the field equipment and testing and logging protocols that have become the fundamental data gathering tools of geo-science practices.


Local universities, led by the geotechnical studies groups at UC Davis and UC Berkeley, will again be bringing 100+ students for this free seminar. The Taber Ranch Vineyard and Event Center has generously donated its facilities and grounds to house the event and Taber Drilling has, as they have for 20+ years, committed to providing exploration/testing equipment and field personnel for the day.




  • Presenters: The Foundation is looking for seasoned engineers and geologists to serve as speaker-teachers at the different drill demonstration stations – mud rotary, hollow stem auger, and electronics (CPT and seismic refraction). The “script” is set for what is covered at each station while presenters add their real-world experiences.


  • Design Firm Sponsors: The Foundation is seeking Company Sponsors from our industry that would like to participate in a “mini job fair”, the 4th station of the class, where they will present their firm’s background and work opportunities to the students (+25 at a time). All sponsors get their company logo on promotional materials and receive a tax deductible receipt for their donation.  Sponsorships are $350 each, all of which goes directly to AEG Scholarships for Students, a direct “give back” and support for the local geo-science community and a gateway to connections with students for internships and employment.


  • Vendors: The Foundation is also looking for industry vendors who regularly collaborate with design firms on geo-technically-driven projects that would like to present their products and services to future design and construction leaders; again, at the 4th station of the class. Vendors are asked to pitch in a tax deductible donation of $500 to support the activities of the day, including lunch for all. Can you suggest an industry vendor and a contact that “should be” at the Drill Class?


If you have interest in volunteering your time as a presenter, having your firm become a sponsor or suggesting an industry vendor . . . or just have questions about the seminar, please contact the class registrar:

AEG to Support California Resolution -Professional Geologist and Geophysicist Week – in honor of 50th Anniversary of “The Geologist Act “

Sacramento AEG Members!

BPELSG (Board of Professional Engineers,  Land Surveyors, and Geologists) has reached out to our chapter for assistance in creating a proposal for a “Professional Geologist and Geophysicist Week” (7/29 – 8/4) in honor of the 50th Anniversary of “The Geologist Act”.  The week would not only be a way to honor the work that geologists and geophysicists do but to educate the public on the importance of our work, provide public awareness to the license that helps to safeguard the public, and be a mechanism of outreach to future geologists and geophysicists.

Laurie Racca, PG  (BPELSG geologist) has provided a first draft and is asking for comments. Please see draft below and email any comments to Meredith Beswick ( 

” Senate Resolution No. XX

Introduced by Senator XXXXX

Professional Geologist and Professional Geophysicist Week

WHEREAS, The history of the State of California is closely tied to the geologic riches of the state, as well as the geologic hazards that exist within the State; and

WHEREAS, The unique geology of the State is the source of the raw materials necessary to create the technologies that help the citizens of California to thrive, the materials used to build the State’s infrastructure, and the source of energy used to power our modern society; and

WHEREAS, An accurate understanding of geology is necessary for the success of all engineered structures within the State, including every building or structure, dam, roadway, landfill, levee and waterway; and

WHEREAS, The protection and management of the water resources of the State, both surface and underground, for the beneficial use of its citizens, is dependent upon an understanding of geology and hydrogeology; and

WHERAS, The geologic profession is critical for the responsible development of geologic resources for the benefit of mankind (e.g. oil and gas, commercial mineral production, construction aggregates etc.), and the mitigation of the negative effects of such development; and

WHEREAS, The citizens of California must deal with the cost, in both dollars and in lives, of natural geologic hazards, such as landslides, earthquakes, volcanic hazards, flooding, coastal erosion, tsunamis, and hazardous minerals; and

WHEREAS, The unique geology of the State also influences the occurrence of man-made hazards such as abandoned mines, or contaminated soil and groundwater, as well as the mitigation of such hazards; and

WHEREAS, An understanding of geology is necessary to meet the goals set by the citizens of California with regards to stewardship of the environment, including the responsible management of hazardous and non-hazardous waste, and confronting climate change; and

WHEREAS, On August 1, 1968, Governor Ronald Reagan signed Assembly Bill 600, “The Geologist Act” into law, creating the State Board of Registration for Geologists, and regulating the geologic profession in California; and

WHEREAS, licensing the geologic profession recommended itself through benefits to the safety, health, and property of the people of California and to the promotion of the public welfare.

WHEREAS, These benefits are in the fields of geology as related to engineering, ground water, mineral exploration and development, geologic hazards, the further development of the science of geology, and other geologic matters of concern to the people of the state; and

WHEREAS, Geophysics is an important branch of geology that uses natural and induced fields of force to study the earth to provide detailed information in situations where other geologic techniques are inadequate; and

WHEREAS, A diverse and vigorous geoscience workforce is necessary to protect the citizens of California, and to ensure resiliency to geologic hazards; and

WHEREAS, August 1, 2018 will mark the 50th Anniversary of “The Geologist Act”; now, therefore, be it

Resolved by the Senate of the State of California, that the Senate hereby proclaims the week of July 29, 2018 through August 4, 2018 inclusive, as Professional Geologist and Geophysicist week and acknowledges the services bestowed upon the citizens of California by licensed geologists and geophysicists; and be it further

Resolved, That the Secretary of the Senate transmit copies of this resolution to the author for appropriate distribution. ”
