Seismic Node Data from Askja Caldera, Iceland, 2023-2024

Seismic node data comprises one month of continuous recording in July/August 2023 and July/August 2024 from the Askja Caldera in Iceland. A total of 14 buried 3-component sensors recorded at 250 samples per second, capturing local earthquakes and teleseisms. The data was collected by the University of Iceland and University of Cambridge for tracking microseismic activity and seismic imaging.

Use Cases

• Tracking microseismic activity associated with volcanic reinflation based on continuous seismic recordings.
• Seismic imaging beneath a caldera using body and surface wave tomography based on 3-component sensor data.
• Detecting and analyzing local earthquakes and teleseisms based on high-quality, continuous seismic data.
• Characterizing geothermal areas near active volcanoes based on seismic node recordings.

Strengths

• Data spans two distinct time periods, July/August 2023 and July/August 2024, providing comparative snapshots.
• 14 seismic nodes with 3-component sensors recording at 250 samples per second.
• Data is described as being of good quality, with both local and distant earthquakes easily detected.
• Data is provided in standard miniseed format with accompanying dataless XML files.

Limitations

• Node distribution was irregular due to access issues, potentially limiting spatial coverage within the caldera.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
