Abstract

This compressed folder contains supporting information related to the manuscript: "Quantifying the statistical relationships between flank eruptions and major earthquakes at Mt. Etna volcano (Italy)".

Data Set S1. Catalog of flank eruptions Historical catalog of flank eruptions of Mt. Etna from 1600 to 2018.

Data Set S2. Catalog of major earthquakes Macroseismic catalog of Etnean earthquakes from 1800 to 2018.

Data Set S3. GIS dataset of Eruptive fissures GIS shapefiles of eruptive fissures at Mt. Etna from 1800 to 2018. UTM WGS84, Zone 33 N.

Data Set S4. Tests with ±2 months maximum inter-event time Histograms of the inter-event time of earthquakes and flank eruptions lesser than ±2 months. Pie charts of the positive values (dark colors), negative values in [-2.5, 0] days (light colors), and lower than -2.5 days (white) are reported.

Data Set S5. Tests with dt = 5 days moving window Conditional rates of major earthquakes less than ±4 months from flank eruptions, obtained assuming dt = 5 days instead of dt = 10 days. A solid line marks the average annual rate of the earthquakes, and bold lines threshold rates 2, 5, and 10 times larger than the average value.

Data Set S6. Tests on the eruptions end, including earthquakes in ±2.5 days from the onset Conditional rates of major earthquakes less than ±4 months from flank eruptions end, obtained without excluding the earthquakes occurred in ±2.5 days from the onset. A solid line marks the average annual rate of the earthquakes, and bold lines threshold rates 2, 5, and 10 times larger than the average value.

Data Set S7. Summary of inter-event time histograms Histograms of the inter-event time of earthquakes and flank eruptions lesser than ±4 months, also decomposed according to spatial groups E1-E4 and fault systems F1-F4. Light-colored bars highlight the eruptions > 2850 m.a.s.l.
