Title: Precise Relative Earthquake Magnitudes from Cross Correlation

Abstract

We present a method to estimate precise relative magnitudes using cross correlation of seismic waveforms. Our method incorporates the intercorrelation of all events in a group of earthquakes, as opposed to individual event pairings relative to a reference event. This method works well when a reliable reference event does not exist. We illustrate the method using vertical strike-slip earthquakes located in the northeast Pacific and Panama fracture zone regions. Our results are generally consistent with the Global Centroid Moment Tensor catalog, which we use to establish a baseline for the relative event sizes.

Relocation of Light and Moderate-Magnitude (M4-6) Seismicity Along the Central Mid-Atlantic

Journal Article Cleveland, Kenneth Michael ; Ammon, Charles J. ; Kintner, Jonas - Geochemistry, Geophysics, Geosystems

Abstract We estimate precise relative epicentroid locations of earthquakes along the Mid‐Atlantic Ridge (MAR) between 12 ° N and 19 ° N using intermediate‐period Rayleigh and Love wave cross‐correlation measurements. We relocate 152 earthquakes with magnitudes ranging between 4.0 and 6.0 and when possible use P waveform modeling to estimate centroid depths. We compare surface‐wave locations to locations in the U.S. Geological Survey, Global Centroid Moment Tensor, and Pacific Marine Environmental Laboratory hydroacoustic catalogs (Smith et al., , https://doi.org/10.1029/2001GL013912) and demonstrate that surface‐wave based relative location techniques provide significant improvement on precision. Our analyses shift locations to more tectonically consistentmore »« less

Bering Sea earthquake of February 21, 1991: Active faulting along the Bering shelf edge

Journal Article Abers, G A ; Ekstroem, G ; Marlow, M S ; ... - Journal of Geophysical Research; (United States)

On February 21, 1991, an M[sub S] = 6.8 shallow earthquake occurred in the eastern Bering Sea in an area which previously has shown no significant seismic activity. The earthquake was located on the Bering Shelf close to the shelf edge, near one of the elongate basins (Zhemchun Basin) that follow the outer shelf. To better understand the causes of this unusual event, we relocated the earthquake and its aftershocks, determined its source mechanism and depth, and examined multichannel seismic observations of structures near the epicenter. The event was relocated from regional and teleseismic P and S arrival times usingmore »« less

Complex Fault Geometry of the 2020 M_ww 6.5 Monte Cristo Range, Nevada, Earthquake Sequence

Journal Article Ruhl, Christine J. ; Morton, Emily A. ; Bormann, Jayne M. ; ... - Seismological Research Letters

On 15 May 2020 an M_ww 6.5 earthquake occurred beneath the Monte Cristo Range in the Mina Deflection region of western Nevada. Rapid deployment of eight temporary seismic stations enabled detailed analysis of its productive and slowly decaying aftershock sequence (p=0.8), which included ~18,000 autodetected events in 3.5 months. Double-difference, waveform-based relative relocation of 16,714 earthquakes reveals a complex network of faults, many of which cross the inferred 35-km-long east–northeast-striking, left-lateral mainshock rupture. Seismicity aligns with left-lateral, right-lateral, and normal mechanism moment tensors of 128 of the largest earthquakes. The mainshock occurred near the middle of the aftershock zone at themore »« less

Precise relative locations for earthquakes in the northeast Pacific region

Journal Article Cleveland, K. Michael ; VanDeMark, Thomas F. ; Ammon, Charles J. - Journal of Geophysical Research. Solid Earth

We report that double-difference methods applied to cross-correlation measured Rayleigh wave time shifts are an effective tool to improve epicentroid locations and relative origin time shifts in remote regions. We apply these methods to seismicity offshore of southwestern Canada and the U.S. Pacific Northwest, occurring along the boundaries of the Pacific and Juan de Fuca (including the Explorer Plate and Gorda Block) Plates. The Blanco, Mendocino, Revere-Dellwood, Nootka, and Sovanco fracture zones host the majority of this seismicity, largely consisting of strike-slip earthquakes. The Explorer, Juan de Fuca, and Gorda spreading ridges join these fracture zones and host normal faultingmore »« less

Determination of earthquake source parameters from waveform data for studies of global and regional seismicity

Journal Article Dziewonski, A M ; Chou, T A ; Woodhouse, J H - J. Geophys. Res.; (United States)

It is possible to use the waveform data not only to derive the source mechanism of an earthquake but also to establish the hypocentral coordinates of the 'best point source' (the centroid of the stress glut density) at a given frequency. Thus two classical problems of seismology are combined into a single procedure. Given as estimate of the origin time, epicentral coordinates and depth, an initial moment tensor is derived using one of the variations of the method described in detail by Gibert and Dziewonski (1975). This set of parameters represents the starting values for an iterative procedure in whichmore »« less
