Improvements in absolute seismometer sensitivity calibration using local earth gravity measurements Improvements in absolute seismometer sensitivity calibration using local earth gravity measurements
The ability to determine both absolute and relative seismic amplitudes is fundamentally limited by the accuracy and precision with which scientists are able to calibrate seismometer sensitivities and characterize their response. Currently, across the Global Seismic Network (GSN), errors in midband sensitivity exceed 3% at the 95% confidence interval and are the least‐constrained response...

Noise reduction in long‐period seismograms by way of array summing Noise reduction in long‐period seismograms by way of array summing
Long‐period (>100 s period) seismic data can often be dominated by instrumental noise as well as local site noise. When multiple collocated sensors are installed at a single site, it is possible to improve the overall station noise levels by applying stacking methods to their traces. We look at the noise reduction in long‐period seismic data by applying the time–frequency phase‐weighted...

Potential improvements in horizontal very broadband seismic data in the IRIS/USGS component of the Global Seismic Network Potential improvements in horizontal very broadband seismic data in the IRIS/USGS component of the Global Seismic Network
The Streckeisen STS‐1 has been the primary vault‐type seismometer used in the over‐150‐station Global Seismographic Network (GSN). This sensor has long been known for its outstanding vertical, very long‐period (e.g., >100 s period), and low‐noise performance, although the horizontal long‐period noise performance is less well known. The STS‐1 is a limited, important resource, because it...

Efforts to monitor and characterize the recent increasing seismicity in central Oklahoma Efforts to monitor and characterize the recent increasing seismicity in central Oklahoma
The sharp increase in seismicity over a broad region of central Oklahoma has raised concerns regarding the source of the activity and its potential hazard to local communities and energy-industry infrastructure. Efforts to monitor and characterize the earthquake sequences in central Oklahoma are reviewed. Since early 2010, numerous organizations have deployed temporary portable seismic...

The data quality analyzer: a quality control program for seismic data The data quality analyzer: a quality control program for seismic data
The U.S. Geological Survey's Albuquerque Seismological Laboratory (ASL) has several initiatives underway to enhance and track the quality of data produced from ASL seismic stations and to improve communication about data problems to the user community. The Data Quality Analyzer (DQA) is one such development and is designed to characterize seismic station data quality in a quantitative...
