In April of 2012 the Plutonium Sustainment program at LANL completed or addressed the following high-level activities: 1) Construction activities on the Low Voltage Electron Beam (LVEB) Welder and Analytical Chemistry gloveboxes have started, successfully closing out MRT L2 Milestone 4195; 2) Completed installation of the Surface Preparation unit in PF4. The unit will be functionally tested in May; 3) Completed casting of the first two near net shape W87 hemishells; 4) Delivered Revision 3 of the Plutonium Sustainment and Manufacturing Study; 5) Completed machining and inspecting the first set of Pollux parts on Precitech 1; 6) Attended the Pu Sustainment Second Quarter Mid-Year Review and the Pit Production Integrated Project Team meeting in Livermore, providing technical updates across the Plutonium Sustainment portfolio; 7) Analyzed the program impact of the LANL Voluntary Separation Program. The analysis determined an impact of 24.6 FTEs and a budget impact of approximately $3.2 Million Dollars of pull back; 8) The Power Supply Assembly Area project received a LANL Pollution Prevention "Gold" award in the category of Cradle-to-Cradle - Cleanouts. A gold award is presented to the number one project in its pollution prevention category. There are currently no major issues associated with achieving MRT L2 Milestones 4195-4198 or the relevant PBIs associated with Plutonium Sustainment. There are no budget issues associated with FY12 final budget guidance. Table 1 identifies all Baseline Change Requests (BCRs) that were initiated, in process, or completed during the month. The earned value metrics overall for LANL are within acceptable thresholds, so no high-level recovery plan is required.

Intended as an introduction to the field, this work on seismology features coverage of the related aspects, from observational data through prediction, emphasizing the fundamental theories and physics governing seismic waves - both natural and anthropogenic. It includes more than 400 illustrations.
