1. Maps of epicenters

​Short description:

Maps of epicenters of earthquakes based on automatic detection and location using RAPL software in the period of September 2013- December 2023. The maps show the same dataset using different magnitude filtration from ML>0 (~ 70k points) up to ML>3 (~1k points) with the same color and symbol radius scaled by magnitude, some also color coded by time or depth.

2. Open access database of earthquakes

Short description:

All events automatically located by RAPL software for the whole 2013-2023 period are available to search, filter and download through phpMyAdmin web UI. Also a set of published moment tensors can be accessed there. More freely available earthquake data produced during NASPMON project will be published there later. The database is called naspmon and a user called naspmon without a password can be used to access the data.

Table description:

• events_rapl – automatically retrieved event locations based on automatic detection and location using RAPL software in the period of September 2013- December 2023 with magnitude above ML>0.
• moment_tensors – moment tensor catalog of events from the 2017 earthquake swarm in Fagradalsfjall (as published in Hrubcová, P., Vavryčuk, V., 2023. Tectonic stress changes related to plate spreading prior to the 2021
  Fagradalsfjall eruption in SW Iceland, Tectonophysics, https://doi.org/10.1016/j.tecto.2023.229761), see detailed column description here.
• moment_tensors_best – moment tensor catalog of the most stable events from the 2017 earthquake swarm in Fagradalsfjall, see detailed column description here.
