Numerical Sheet for "Station-orientation catalog for Australian broadband seismic stations"
<p>This XLSX file includes the numerical values for Tables S1-S3.</p> <p>This XLSX file includes the station orientation catalog for all stations estimated in Tarumi & Yoshizawa (2024, submitted to Seismica) (Sheet Tab1: Permanent stations excluding the S1 network; Sheet Tab2: the S1 network stations; Sheet Tab3: Temporary stations). The first column is an index number; the second includes the network code and station name. The third and fourth columns represent the period (start and end time) for calculating two statistical values (the median and mean) of station orientation (in the fifth and sixth columns, respectively) and its standard errors (seventh columns). The last column indicates the number of earthquakes used to estimate the misorientation during the designated period. All information is the same as in Tables S1–S3. </p> <p>"codesample.zip" includes the sample program (Jupyter notebook) and the sample data. </p>
Broadband waveforms for teleseismic receiver functions in the northwestern part of South America
<p>This dataset provides a comprehensive collection of teleseismic events occurring within an epicentral distance range spanning 30° to 130°, featuring a minimum magnitude threshold of Mw > 4.5. Data from 98 triaxial broadband seismological stations affiliated with three distinct seismological networks: the Colombian Geological Survey (RSNC), IRIS-PASSCAL Consortium/USGS, and Volcanological Observatories are incorporated in this dataset. These recordings span the period from 1999 to 2021. The raw waveforms are updated, these were trimmed several seconds before and after the P-wave arrival.</p><p>The dataset is systematically arranged in chronological order based on teleseismic events and is presented in the SAC format. Geospatial information pertaining to each event is encapsulated within the header file.</p>

Data from: Epidemiological survey of the feasibility of broadband ultrasound attenuation measured using calcaneal quantitative ultrasound to predict the incidence of falls in the middle aged and elderly
Objectives: We investigated whether calcaneal quantitative ultrasound (QUS-C) is a feasible tool for predicting the incidence of falls. Design: Prospective epidemiological cohort study. Setting: Community-dwelling people sampled in central western Taiwan. Participants: A cohort of community-dwelling people who were ≥40 years old (men: 524; women: 676) in 2009–2010. Follow-up questionnaires were completed by 186 men and 257 women in 2012. Methods: Structured questionnaires and broadband ultrasound attenuation (BUA) data were obtained in 2009–2010 using QUS-C, and follow-up surveys were done in a telephone interview in 2012. Using a binary logistic regression model, the risk factors associated with a new fall during follow-up were analysed with all significant variables from the bivariate comparisons and theoretically important variables. Primary outcome measures: The incidence of falls was determined when the first new fall occurred during the follow-up period. The mean follow-up time was 2.83 years. Results: The total incidence of falls was 28.0 per 1000 person-years for the ≥40 year old group (all participants), 23.3 per 1000 person-years for the 40–70 year old group, and 45.6 per 1000 person-years for the ≥70 year old group. Using multiple logistic regression models, the independent factors were current smoking, living alone, psychiatric drug usage and lower BUA (OR 0.93; 95% CI 0.88 to 0.99, p<0.05) in the ≥70 year old group. Conclusions: The incidence of falls was highest in the ≥70 year old group. Using QUS-C-derived BUA is feasible for predicting the incidence of falls in community-dwelling elderly people aged ≥70 years.
