World-Wide Standardized Seismographic Network Film Chip Scans World-Wide Standardized Seismographic Network Film Chip Scans
These are the scanned digital images of microfilm copies of paper seismic records from the World-Wide Standardized Seismographic Network (WWSSN). This data set spans from 1962 to 1978 and contains about 3.7 million single-day records, which is about 5% of the entire archive. Overall the data set contains 153 magnitude 6+ earthquakes and 156 nuclear explosions. All scans were done using...
A review of timing accuracy across the Global Seismographic Network A review of timing accuracy across the Global Seismographic Network
The accuracy of timing across a seismic network is important for locating earthquakes as well as studies that use phase‐arrival information (e.g., tomography). The Global Seismographic Network (GSN) was designed with the goal of having reported timing be better than 10 ms. In this work, we provide a brief overview of how timing is kept across the GSN and discuss how clock‐quality metrics...

Sensor suite: The Albuquerque Seismological Laboratory Instrumentation Testing Suite Sensor suite: The Albuquerque Seismological Laboratory Instrumentation Testing Suite
To standardize parameters used in seismometer testing and calibration and to make these algorithms accessible to the seismological community, we have developed a new seismometer testing software package called Albuquerque Seismological Laboratory (ASL) Sensor Test Suite. This software is written in Java and makes use of Seismological Exchange for Earthquake Data (SEED) format. Our goal...

Size distribution of rare earth elements in coal ash Size distribution of rare earth elements in coal ash
Rare earth elements (REEs) are utilized in various applications that are vital to the automotive, petrochemical, medical, and information technology industries. As world demand for REEs increases, critical shortages are expected. Due to the retention of REEs during coal combustion, coal fly ash is increasingly considered a potential resource. Previous studies have demonstrated that coal...

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...
