“…The bulk of the macroseismic data was collected using the internet questionnaire. It is worth noting that since 2008 earthquakes in the Baikal region were not characterized by a high magnitude and the number of eyewitness responses, as a rule, did not exceed several hundred (Radziminovich et al 2014(Radziminovich et al , 2020; nevertheless, in the case of the Mw 5.5 Kudara earthquake 1433 responses were received from 120 settlements in Eastern Siberia. The majority of these places are located in the far-field, only seven are located in the near-field and are among those covered by the field survey.…”

“…The collection of macroseismic data was carried out mainly using an internet questionnaire posted on the website of the Baikal Branch of the Geophysical Survey of the Russian Academy of Sciences (GS RAS) ( http://seis-bykl.ru ). The questionnaire was put into operation in September 2008 after the experience of studying of strong August 27, 2008, M w 6.3 Kultuk earthquake in order to obtain a broader public response and significantly increase the amount of macroseismic data (Radziminovich et al 2014 ).…”

The article discusses the macroseismic data on the December 9, 2020, M w 5.5 Kudara earthquake which occurred in the Selenga River delta (Middle Baikal, Eastern Siberia, Russia). This is the strongest seismic event in the study area over a 50-year period. The bulk of macroseismic data was obtained with internet questionnaire posted on the website of the Baikal Branch of the Geophysical Survey of the Russian Academy of Sciences. In total, 1433 responses were received from 120 places (villages, towns and cities) in Eastern Siberia, with most of them was obtained from large cities. In addition, a field survey was carried out in the near-field, which revealed slight non-structural damage to buildings in several settlements. The maximum intensity assessed VI–VII MSK-64 or VI EMS-98 was observed in the Kudara village. Taking into account the macroseismic data obtained, we have prepared a map of intensity data points. The largely observed shakings (intensity IV MSK-64/EMS-98) were noted at epicentral distances of over 500 km; intensity II MSK-64/EMS-98 was noted at a distance of up to 980 km. The Kudara earthquake allowed us to test the internet questionnaire in real conditions of strong seismic impact. The results obtained confirm the rather high efficiency of the internet questionnaire in the conditions of the Baikal region, however, some limitations associated with the responses spatial distribution are exist. A detailed study of the Kudara earthquake allowed us to gain new experience useful for the further development of macroseismology in Eastern Siberia.

“…Nowadays, considering that crowdsourcing has gained more attention in several fields of interest, web-based macroseismic intensity questionnaires are used by many organisations (Radziminovich et al 2014;Van Noten et al 2017). The development of automated methods for determining intensity (Ringdal et al 1978;Gasparini et al 1992;Ferrari et al 1995;Musson 2006;Mazet-Roux et al 2010;Sbarra and Tosi 2010;Wald et al 2012;Tosi et al 2015;Vannucci et al 2015;Goded et al 2018) and the availability of large amounts of data have paved the way for the quantification of each diagnostic effect, thus guaranteeing a more objective assessment of macroseismic intensity.…”

Quantification of earthquake diagnostic effects to assess low macroseismic intensities

A large amount of data about earthquake effects, supplied by citizens through a web-based questionnaire, enabled the analysis of the occurrence of many of the effects on humans and objects listed in macroseismic scales descriptions. Regarding the other diagnostic effects (rattling, moving, shifting, falling or overturning depending of the object type of doors, windows, china, glasses, small objects, pictures, vases, books, as well as frightened people and animal behaviour), data from more than 300,000 questionnaires about earthquakes felt in Italy from June 2007 to August 2017, were analysed by stacking them together as a function of hypocentral distance and magnitude. The comparison of the resulting percentages with the intensity prediction equation showed that almost all the chosen effects are good diagnostics for macroseismic intensity evaluation, as their percentages are well differentiated. We did not analyse the oscillations of hanging objects and liquids because the differences in effect attenuations, highlighted by the maps of the occurrence percentage, suggested to not consider them as diagnostic effect. This result allowed us to quantify the occurrence of each diagnostic effect for the intensity degrees from II to VI of the European macroseismic scale for the people who felt the earthquake. The application of the intensity assessment method to internet macroseismic data, based on the specifications herein proposed, should mitigate the problem of “not felt” undersampling in crowdsourced web data.
