Illustration of the doughnut effect for (a) the 7 November 2016 M 5 Cushing, Oklahoma, earthquake and (b) the 30 October 2016 M 6.6 Norcia, Italy, earthquake. For the Cushing earthquake, the maximum “Did You Feel It?” (DYFI) intensity is of 6.7 at 5.5 km of the epicenter (see Data and Resources). The maximum DYFI intensity is 9 in Norcia for the eponym earthquake (see Data and Resources). There were no application launches nor felt reports collected within 10 min and 15 km of the Cushing epicenter (a), this gap being filled after 10 min. For the damaging Norcia earthquake, within the same time and distance windows, only one damaging felt report was collected. No other felt reports were collected within 15 km of the epicenter, despite several late (i.e., after 10 min) application launches. Only observations collected within 1 hr of the earthquakes are presented.
