While the standard focuses on ground motion, it recognizes that earthquakes can trigger other dangerous phenomena. API RP 2EQ explicitly directs engineers to consider associated geological hazards, including:
Given the critical nature of this standard for safe design, it is vital to use an official copy. Unauthorized or outdated versions found on third-party websites may contain errors or missing amendments and carry significant legal and safety risks. The document is protected by copyright, and official PDFs typically include security features that restrict reproduction and distribution. The best way to obtain the official PDF is to purchase a license from an authorized distributor.
The practice emphasizes a risk-based approach. It requires engineers to evaluate the probability of ground shaking at a specific site. This involves choosing between a deterministic approach (based on known faults) or a probabilistic approach (calculating the likelihood of various magnitudes).

: API RP 2EQ replaces the older seismic zone maps used in API 2A-WSD (21st Edition and earlier) with ISO-aligned site-specific seismic zones. Recent Addenda and Reaffirmations
: The complete 104-page PDF is available for purchase through the API Standards Store or authorized distributors like BSB Edge and Standards.ie . While the standard focuses on ground motion, it
(roughly 2.0), RP 2EQ allows for regional variations and a range of factors based on the specific structural configuration. Seismic Maps:
: Blends international criteria with localized geographic data mapping for high-risk zones like Southern California and Alaska. Key Technical Updates in the Active Edition The document is protected by copyright, and official
For older platforms, a new PDF update might trigger a need for structural reinforcement.
Better understanding of how aged steel or reinforced concrete reacts to repetitive seismic loading.
