Experimental data related to publication: "Dislocation Avalanches: Earthquakes on the MicronScale"
<p>Each .tar file corresponds to a single micropillar compression experiment. The nomenclature of the uploaded dia_<strong>{dia}</strong>_v_<strong>{v}</strong>_p_<strong>{p}</strong>.tar files is the following:</p> <ul> <li>{dia}: The diameter of the micropillar in µm</li> <li>{v}: The compression platen velocity in µm / s</li> <li>{p}: Unique identifier of the micropillar for a given diameter and compression platen velocity</li> </ul> <p>The tar files have the following content:</p> <ul> <li>A tar.gz file which contains the raw Acoustic Emission (AE) data in a compressed file format. Uncompressing it results in one or multiple wav files. In case of multiple ones the covered time range is included at the end of the file name like: 300to800 means the time interval from the compression experiment between 300 s and 800 s. The units of the AE measurement data is 0.1 mV and the sampling rate is 25 MHz.</li> <li>The raw data from the nanoindenter (time, force, displacement, etc.) is located in the file with .dat extension.</li> </ul>

Two global ensemble M5.95+ seismicity models obtained from the combination of interseismic strain rates and earthquake-catalogue data
<p>Contains two global earthquake-rate forecasts developed by Bayona et al. (2021) to be prospectively evaluated by the Collaboratory for the Study of Earthquake Predictability (CSEP). The Tectonic Earthquake Activity Model (TEAM) is a geodetic-based model using Version 2.1 of the Global Strain Rate Map (GSRM2.1; Kreemer et al., 2014), while the World Hybrid Earthquake Estimates based on Likelihood scores (WHEEL) is a model obtained from a multiplicative log-linear combination of TEAM with the Smoothed Seismicity (KJSS) model of Kagan and Jackson (2011).</p> <p>Earthquake densities are expressed as number of M5.95+ events per unit 0.1<sup>o</sup> cell per year. The forecasts are stored in tab separated value files, with the following fields (the first row of data is shown as an example):</p> <table> <tbody> <tr> <td><sub>lon_min</sub></td> <td><sub>lon_max</sub></td> <td><sub>lat_min</sub></td> <td><sub>lat_max</sub></td> <td><sub>depth_min</sub></td> <td><sub>depth_max</sub></td> <td><sub>5.95</sub></td> <td><sub>6.05</sub></td> <td>...</td> </tr> <tr> <td><sub>-180.0</sub></td> <td><sub>-179.9</sub></td> <td><sub>-90.0</sub></td> <td><sub>-89.9</sub></td> <td><sub>0.0</sub></td> <td><sub>70.0</sub></td> <td><sub>4.95e-11</sub></td> <td><sub>3.97e-11</sub></td> <td>...</td> </tr> </tbody> </table> <p>Data and forecasts are described in detail in the following publications:</p> <p>Bayona, J.A., Savran, W., Strader, A., Hainzl, S., Cotton, F. and Schorlemmer, D., 2021.
