This results in one of the highest levels of seismicity in the conterminous United States (e.g., Evernden, 1970). In southern California, the deformation is spread over a large area, encompassing numerous normal, strike-slip, and reverse faults. A majority of the plate motion appears to be accommodated by the San Andreas fault, with the rest distributed among the dozen or so other major faults (Weldon and Humphreys, 1986). This is in contrast to the plate boundary in northern California, where the plate motion is more concentrated near the San Andreas fault than it is in southern California (e.g., Hill and others, this volume).

", "abstract": "What is the nature of earthquake ground motions that can be expected in San Diego's\nforeseeable future? Although this is the most basic of questions underlying the adequate design\nof structures to resist earthquakes, answers to this question are disturbingly uncertain. A\nreasonable assumption is that future earthquake ground motions will be similar to those that have\noccurred in the past. When compared with San Francisco or Los Angeles, San Diego has\nhistorically experienced relatively mild earthquake shaking. Unfortunately, San Diego's written\nhistory is very short compared to the time scales of earthquake repetition. Are there sources of\nearthquakes that may cause damage in San Diego and what is their frequency? Mapping of\ngeologic structures and the study of patterns of small earthquakes are the primary tools for\nrecognizing potentially active faults. There are features in both the geologic structure and the\nseismicity that are suggestive of major active faults that could pose a serious hazard to San\nDiego. Furthermore, there is evidence that the rate of occurrence of small earthquakes has\nincreased within the last 5 years when compared with the previous 50 years. However, these\nfeatures are not well studied or understood.\nEven if the potential sources of earthquakes were well understood, the problem of anticipating the\nrange of future ground motions is difficult. The nature of shaking from earthquakes is strongly\naffected by the nature of seismic wave propagation through complex geologic structures (path\neffects). Although path effects are likely to be of great importance in San Diego, relatively little\nspecific information is available.", "date": "1989-06", "date_type": "published", "publisher": "Southern California Earthquake Preparedness Project", "id_number": "CaltechAUTHORS:20121127-134135015", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20121127-134135015", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Division-of-Geological-and-Planetary-Sciences" } ] }, "contributors": { "items": [ { "id": "Roquemore-G", "name": { "family": "Roquemore", "given": "Glenn" } } ] }, "primary_object": { "basename": "Heaton_1989p42.pdf", "url": "https://authors.library.caltech.edu/records/576gg-rzz15/files/Heaton_1989p42.pdf" }, "resource_type": "book_section", "pub_year": "1989", "author_list": "Heaton, Thomas H. and Jones, Lucile M." } ]
