Description:
Abstract:
The U.S. Geological Survey collected high-resolution single channel minisparker data between Point Sal and Piedras Blancas in 2008 and 2009 with support from the Pacific Gas and Electric (PG&E) CRADA and the USGS Coastal and Marine Geology program. Reprocessing of this data in 2018 improved vertical resolution of the stratigraphy and structural deformation of the original data and was funded by an additional CRADA with PG&E.
Purpose:
This work will aid the USGS in reviewing and refining existing interpretations, hazard assessments and development of new hypotheses. Particular targets include the Hosgri-San Gregorio fault system, and the Los Osos, and Shoreline faults. The ultimate goal of this work for both parties is to enhance earthquake hazard assessments by providing a more comprehensive understanding of regional geologic framework, seismic sequence stratigraphy and hazard assessment. These data and information are intended for science researchers, students, policy makers, and the general public.

Data_Set_Credit:
This dataset was collected by the U.S. Geological Survey in 2008 and 2009. Work was funded in part by a CRADA agreement between PG&E and the USGS and these data were made publicly available in 2009 (Sliter and others, 2009).
Native_Data_Set_Environment:
Single channel minisparker data were recorded in SEG-D rev. 2.1 format (
https://seg.org/Portals/0/SEG/News%20and%20Resources/Technical%20Standards/seg_d_rev2.1.pdf) using Geometrics CNT-1 seismic acquisition software. A SIG 2Mille 50-tip minisparker operated at 500J was used as the seismic source and SEG-D format data were acquired using a 15-meter-long single channel hydrophone that was towed aft of the stern. Survey speeds were approximately 4.5 knots. Data were converted to SEG-Y format and were minimally processed and released in 2009 (Sliter and others, 2009). For reprocessing efforts utilized SIOSEIS and Seismic Unix software.
