...Rebecca L. Rodd; Ronald A. Brogan; Josh D. Carmichael; Amanda C. Price; Chris J. Young ABSTRACT Multimodal, curated data sets and nuisance event catalogs remain rare in the explosion monitoring community relative to curated seismic data sets. The source of this relative absence is the difficultly...

... or national catalogs. Events locate in a narrow geographic band, with one‐fourth exhibiting multimodal hypocentral probability peaks both near the surface and at 1–4 km depth. We relocate events with a joint hypocenter and 1D velocity model inversion, in addition to a fully nonlinear method, and then compare...

... from a buried chemical explosion conducted at the NNSS as a part of the Source Physics Experiment, Phase II Dry Alluvium series ( Snelson et al. , 2013 ). In addition to waveform data, the database contains a reviewed event catalog from 31 multimodal stations as well as station metadata. The catalog...

.... As a learning dataset, we use the Global CMT catalog ( Dziewonski et al. , 1981 ; Ekström et al. , 2012 ), with all the events without any selection of magnitude and with a maximum depth of 70 km. Using all events, without any constraints in the magnitude, allow us to capture the possible multimodal behavior...

... seismicity: spatiotemporal μ ST ( x , y , t ) = f ( x , y ) is often a spatial function or constant. Temporal μ T is the integral of μ ST over the catalog spatial domain Spatiotempotal, temporal rate of background earthquakes K Events N ( M ) = K...

.... We introduce the new concept of a magnitude completeness interval consisting of a maximum magnitude of completeness ( M c(max) ) in addition to the well‐known minimum magnitude of completeness. This is required to describe the completeness of the catalog, both for the smallest events (for which...

... to stationary, nonstationary, and even multimodal nonstationary seismicity rates. The significance of the method is tested using synthetic catalogs extracted from stationary (exponential based on a Poisson process) and nonstationary (mixed bimodal Weibull–Weibull, gamma, and log‐normal) distributions...

... on the Quebrada, Discovery, Gofar, Wilkes, Yaquina, and Siqueiros transforms. The mainshock catalog contains 46 events between 1996 and 2002 that were not preceded in the previous week by an M w  5.0 event on the same fault system. Blue dots indicate the success rates for logorithmically spaced alarm durations...

Enhanced capabilities include generating a seismic catalog from event summary files, seamlessly integrating information from source spectrum analyses and moment tensor inversions...

... phase-shift transform is shown in Figure  9a . The horizontal location of the microseismic event used for modified phase-shift transformation is obtained from the surface catalog. As we use the long-offset criterion, only guided P-SV modes are visible. We observe multiple dispersion modes that can...

... designs are optimized for BASW considering the fundamental and higher mode dispersion trends of the Rayleigh wave. Synthetic and field data were used to demonstrate multimode BASW and mode separation, which accentuated individual scatter events, and ultimately increased confidence in points of interest...

... more than one distinct solution. We illustrate the utility of an NGA via a multimodal seismological inverse problem: the inversion of teleseismic body waves for the source parameters of the M W 7.2 Kuril Islands event of 2 February 1996. We assume the source to be a pure double-couple event and so...

... events every year from 2009 to 2011. However, after the inclusion of BATS and network upgrading in the beginning of 2012, more than 30,000 events are reported every year in the Taiwan region. We investigated the earthquake catalog for these events, for which regional magnitude completeness ( M c...

The effect of the trade‐off becomes clearer when we compare the percentage of the events in the template matching catalog ( Shelly, 2020 ) reproduced by the Dice and the BCE models after applying different thresholds on the prediction scores (Fig.  4 , Fig. S10). Here, we assumed...

... name at the top of the figure. In A–C, the ISC-EHB catalog does not contain events after 2017 and moment magnitude is not available for each event, therefore the number of earthquakes may not match with those of the other panels and they are plotted in uniform black circles. In D–I, an event is marked...

Vieceli Abstract Individual seismic catalogs can contain multiscale observations from fault level to global scales and associated waveforms from discrete events reflect crustal structure across many different scales and locations.
