Felt reports were received for five of the tectonic earthquakes. The largest earthquake reported during the year was mb(Lg) = 2.8 occurring on July 5, 1996. The epicenter was in Cherokee County, North Carolina. Figure 1 is an epicenter map of earthquakes located during the report period. Figures 2 and 3 are cumulative epicenter maps for the period from July 1977 through December 1996, covered by SEUSSN Bulletins 1 through 31. SOUTHEASTERN U.S. EARTHQUAKES DURING 1996 lists hypocentral parameters, magnitudes, and arrival times for tectonic earthquakes and two mining induced earthquakes in the southeastern United States. SOUTHEASTERN U.S. RESERVOIR ACTIVITY DURING 1996 lists hypocentral parameters, magnitudes, and arrival times for earthquakes near the Monticello and Jocassee Reservoirs in South Carolina. SEISMIC STATION LISTING AND NETWORK MAPS contains a listing of seismic stations operating during the report period and maps showing the major network operators in the region. The SEUSSN monitoring area is considered to include all of Florida, Georgia, Alabama, South Carolina, North Carolina, Virginia, West Virginia (south of latitude 37.72 deg N), Maryland, and Delaware; and includes Tennessee and Kentucky - east of longitude 87 degrees West (see Figure 5). INTERNET ACCESS TO SOUTHEASTERN U.S. EARTHQUAKE CATALOG INFORMATION AND ELECTRONIC VERSIONS OF THE BULLETIN describes how to download southeastern U.S. earthquake catalogs and electronic versions of the SEUSSN Bulletins via the Virginia Tech Seismological Observatory website http://www.geol.vt.edu/outreach/vtso). DEFINITIONS AND NETWORK OPERATOR CODES contains definitions of various terms and abbreviations used in the Bulletin as well as a listing of codes for network operators and/or contributors. APPENDIX A includes abstracts of papers by Bulletin contributors presented at the 1996 Seismological Society of America Meeting (St. Louis, Missouri) and the Eastern Section, Seismological Society of America Meeting (Chapel Hill, North Carolina).

ACCESSING DIGITAL WAVEFORM DATA AND OTHER INFORMATION FROM THE VIRGINIA TECH SEISMOLOGICAL OBSERVATORY OVERVIEW: The Virginia Tech Seismological Observatory has established computer access to its catalog and digital waveform data via the worldwide web (http://www.geol.vt.edu/outreach/vtso.html) gopher, and anonymous ftp servers, also on node www.geol.vt.edu (128.173.184.38). Waveform data currently available include event data from the Virginia Regional Seismic Network and from the GSE (GSETT-2) short-period and broadband instruments located at Blacksburg, Virginia (co-sited with WWSSN station BLA). Network data files consist of 32 channels, digitized at 100 sps at the Blacksburg collection node, from ten sites in Virginia and West Virginia (currently). This acquisition system is being upgraded from its present 40 dB of dynamic range to a system with over 100 dB of dynamic range. The GSE data consist of six channels recorded with a 24 bit digitizer. The three short-period channels are sampled at 40 sps and the three broadband channels at 10 sps. Both the network and GSE stations are calibrated. A brief description of the available data is given below. For further information, help files are provided on the ftp and gopher servers. If one has problems or wants data in a format other than that provided, contact Martin Chapman (chapman@vtso.geol.vt.edu or 540-231-5036). The BLA USNSN equipment officially went on-line in May 1995, but, as of this writing, has produced little data because of hardware problems. The borehole instruments are a three-component broadband sensor package from Guralp. The waveform data are available from the U.S. Geological Survey in Golden via the AutoDRM retrieval system. NEAR-REAL-TIME WAVEFORM DATA: Every 20 minutes, triggered event waveform data files from the Virginia Regional Seismic Network are transferred from the digital acquisition system to the anonymous ftp account on www.geol.vt.edu. These data are raw triggers with no event information. The data are in demultiplexed UNIX_SUDS_1 format. The source code and an executable version of a program to convert from UNIX_SUDS_1 format to SAC format (called st2sac) is available on the directory where these data files are located. SELECTED DIGITAL WAVEFORM DATA SETS: For events of particular interest, processed waveform data sets from the network and/or the GSE are prepared and put in subdirectories accessible through ftp and/or gopher. Network waveform data will have the timing and digitizing rates double-checked against a satellite time code channel. The waveform data are in either the SAC or the Center for Seismic Studies (CSS) database structure binary formats. OTHER INFORMATION AVAILABLE: Other data and information available from the Virginia Tech Seismological Observatory (node: vtso.geol.vt.edu) include: ????????????? Updated overview of available information by finger, telnet, or e-mail from quake@vtso.geol.vt.edu. ????????????? Unprocessed data from the GSE station for selected events (in binary CSS format). ???????????? Channel information such as station locations, instrument responses (in both pole-zero and frequency-amplitude-phase formats), station calibration histories, etc. ????????? Southeastern U. S. Seismic Network (SEUSSN) Bulletins. ????????? SEUSSN earthquake catalog (for July 1977 through the current Bulletin) and a catalog of historic and instrumentally located earthquakes for the southeastern United States (from the year 1698 through the current Bulletin). DEFINITIONS AND NETWORK OPERATOR CODES Below are some entries in this Bulletin that might require definition. Also given is a detailed listing of agencies or groups (and their letter codes) that supply information to this Bulletin. AZM: Azimuthal angle from epicenter to station as measured from north (in deg), DEP: Focal depth estimate (in km); FXD indicates that the depth was held fixed during the epicentral determination, DIST (KM) Epicentral distance (in km) between the epicenter and a station, ERROR ELLIPSE: Semi-axes, expressed as lengths (km) and azimuths (deg), of the vertical projection of the error ellipsoid (Lahr, 1980). Horizontal axes are expressed as the semi-major axis (ERHMAX), it's azimuth (AZ), and the semi-minor axis (ERHMIN). The vertical axis (ERZ) is the largest vertical deviation of the error ellipsoid from the hypocenter. A quality measure (Q) for the ellipsoid based on the length of the largest semi-axis (ERHMAX, ERHMIN, or ERZ) may also be supplied. For this Bulletin the following statistics apply for error estimates: CERI, TVA, and VTSO: Error ellipse projected semi-axes from HYPOELLIPSE corresponding to a chi-square statistic (68%) with one degree of freedom, GIT: Error ellipse projected semi-axes from LOCA, and USC: Standard error estimates from HYPO71. NEIC and USGS: Unknown, GAP: The largest azimuthal separation (in deg) between recording stations, HYPOELLIPSE: Computer hypocenter location program (Lahr, 1980), HYPO71: Computer hypocenter location program (Lee and Lahr, 1974), LOCA: Computer hypocenter location program developed at the Georgia Institute of Technology, MBN or mb(Lg): Body wave magnitude determination using Nuttli's formulas for the Lg phase (Nuttli, 1973), MDB, MDL, MD: Duration/coda length magnitude that approximates either the mb, ML, or an unknown magnitude scale, respectively. As of June 1986 (SEUSSN Bulletin 17), those using a duration magnitude approximating mb(Lg) are CERI, DGS, GIT, TVA and VTSO. Specifically: CERI: MDB = -2.36 + 2.23 Log(D) + 0.12 Log(K) (MDB > 2.6) MDB = -3.38 + 2.74 Log(D) (MDB < 2.7) VTSO, TVA, and GIT: MDB = -3.45 + 2.85 Log(D) where D is signal duration measured from the P-wave arrival time to the time when the signal returns to background noise, and K is the epicentral distance in kilometers. Those using a duration magnitude approximating ML are USC and USGS. Specifically: USGS: MDL = -0.87 + 2.0 Log(D) + 0.0035 X where D is signal duration measured from the P-wave arrival time to the time when the signal returns to twice background noise, and X is the epicentral distance in kilometers. For more information please see SEUSSN Bulletin 17 (page 1) or contact the agency making the estimate for details on their specific procedure, ML: Local magnitude; contact the agency or group making the estimate for details on their specific procedure, NO: Number of P, S, and S-P readings used in locating the event, PHASE: Phase descriptions for either P or S waves, or S-P times. Included under this heading may also be the descriptors; 'i' for an impulsive arrival or 'e' for an emergent arrival. Preliminary first motions may also be given for P wave polarities. These include; 'u', 'c', or '+' for a compressional first arrival, and 'd' or '-' for a dilatational first arrival. '?' indicates that the arrival time is questionable. Q: Solution quality of the hypocenter (the average of the SQD quality measures, see below; Lee and Lahr, 1974), RES: Arrival time residual (the difference between the observed and the calculated arrival time, in seconds). An "X" following the value of the arrival time residual means that the arrival time was not used to compute the location of that event, RMS: Root-mean-square of the weighted arrival time residuals (in sec), S-P: Difference between the S and P wave arrival times (in sec), SQD: Measures of the statistical quality of the solution (S), and of the distribution of stations (D) around the hypocenter (Lee and Lahr, 1974), *XXXX: Code indicating the agency or group that made the hypocentral/magnitude determination; a listing of agencies and groups that operate seismographs in the SEUSSN and/or who supply information to this BULLETIN follows.

Appendix A Seismological Society of America Meeting GEOPHYSICAL AND GEOLOGICAL RECONNAISSANCE OF SEISMICALLY-INDUCED SAND DIKES AND RELATED SAND BLOWS IN THE NEW MADRID SEISMIC ZONE WOLF, L. and COLLIER, J., Auburn University, Auburn, AL; BODIN, P., CERI, University of Memphis, Memphis, TN 38152; TUTTLE, M., University of Maryland, College Park, MD, BARSTOW, N., LDEO of Columbia University, Palisades, NY; GOMBERG, J., U.S. Geological Survey The geometry of sand dikes and related sand blows induced by strong ground motion during prehistoric earthquakes was determined by shallow geophysical methods. We conducted electrical resistivity and conductivity surveys at two sites in the seismic zone. At one of the study sites, buried prehistoric sand dikes and sand blows had been exposed during an archeological survey and later examined as part of a paleoseismology study (Tuttle et al, this volume). At the other site, a possible sand blow was identified by interpretation of aerial photographs and surface reconnaissance, but was undisturbed at the time of the geophysical survey. Both liquefaction sites occur within the Holocene floodplain of the meandering Mississippi River. Here sand blows typically form elliptical patches of sandy soils in otherwise fine-grained soils. Following the geophysical survey at the second site, two trenches were excavated and logged. Samples from soil and Native American occupation horizons, liquefaction features, and sediment layers within the trenches were collected for sedimentological analyses. We also measured the distribution of cotton plant heights, which may reflect variations in shallow soil composition. This information will be used to correlate geophysical signatures with sedimentological and archeological features. Preliminary results indicate that conventional resistivity methods (Wenner array) may be quite useful for identifying and mapping small (~50 cm wide) shallow sand dikes. Disruption of the regional sedimentological trends, both by an echelon arrangement of sand dikes and by the related sand blow, is clearly revealed in the combined geophysical and agricultural data. Dike signatures appear as small perturbations on longer wavelength signals that reflect the larger-scale environment of deposition (i.e., Mississippi River point bar and channel deposits). Electromagnetic methods (EM-31), while less sensitive to dike locations, may be useful for locating Native American occupation horizons. Identifying and mapping sand dikes with geophysical techniques is useful for siting trenches during paleoseismic investigations. Moreover, mapping buried sand dikes may help characterize ground motions during prehistoric earthquakes and determine the physical properties of sedimentary layers associated with ground failure.
