Charts showing eruption recurrence rates of age groups in Harrat Khaybar and average rates of selected basaltic volcanic fields around the world. a Chart of the recurrence rates among age groups at Harrat Khaybar. b Chart comparing average temporal recurrence rates of well-studied distributed volcanic fields in the world including Harrat Khaybar. All data points are averages calculated from the known number of vents divided by the longevity of the field. Chart a) demonstrates that average rates shown in b) do not adequately characterize the temporal variation of activity in a field.
