In view of the concept that macroseismic intensity enables us to categorise the extent and severity of damage to buildings and structures caused by an earthquake, this study aims to compile a macro-seismic intensity-based catalogue of earthquakes in Ecuador, characterise the epicentral macroseismic intensities associated to seismogenic sources and perform a comparison with the National Seismic Hazard Map. This paper is the first that presents a catalogue of earthquakes with macroseismic intensities ≥VII and a series of maps of earthquake epicentres according to intensity, focal depth, data and magnitude of seismic events in Ecuador, based on the study of historical and instrumental records from 1900 to 2021. The obtained data shows that 95% of the territory of Ecuador has a PGA &gt; 0.1 g, which corresponds to seismic intensities greater than VII, while regions with seismicity&gt;VIII (ag = 0.2 g) constitute 86%, and 3.8% of the territory of Ecuador has very high seismicity (&gt;IX), where the PGA exceeds 0.5 g. This information suggests that the normative National Seismic Hazard Map of Ecuador underestimate the hazard mainly in the south-east and in the Central Andes of Ecuador, and require an actualization.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Каталоги магнитуд землетрясений и карты пиковых ускорений грунта (ПУГ, англ. PGA) для Республики Эквадор можно найти во многих исследованиях, однако работы, посвященные характеристике эпицентральной макросейсмической интенсивности, связанной с землетрясениями, встречаются редко. В связи с тем, что макросейсмическая интенсивность позволяет классифицировать степень и тяжесть ущерба, нанесенного землетрясением зданиям и сооружениям, целями данного исследования стали: 1) составление каталога землетрясений в Эквадоре на основе макросейсмической интенсивности; 2) характеристика эпицентральных макросейсмических интенсивностей, связанных с сейсмогенными источниками; 3) сравнение с Национальной картой сейсмической опасности. Впервые представлены каталог землетрясений с макросейсмической интенсивностью ≥VII и серия карт эпицентров землетрясений в соответствии с интенсивностью, глубиной очага, данными и магнитудой сейсмических событий в Эквадоре, основанных на изучении исторических и инструментальных записей с 1900 по 2021 г. Полученные данные показывают, что 95 % территории Эквадора имеют PGA &gt; 0,1 g, что соответствует сейсмической интенсивности более VII, регионы с сейсмичностью &gt;VIII (ag = 0,2 g) составляют 86 %, а 3,8 % территории Эквадора имеют очень высокую сейсмичность (&gt;IX), где PGA превышает 0,5 g. Это свидетельствует о том, что нормативная Национальная карта сейсмической опасности Эквадора не учитывает опасность в основном на юго-востоке и в Центральных Андах Эквадора и требует актуализации.</p></trans-abstract><kwd-group xml:lang="en"><kwd>earthquake</kwd><kwd>Ecuador</kwd><kwd>macroseismic intensity</kwd><kwd>seismic hazard</kwd><kwd>seismicity</kwd><kwd>structural design</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>землетрясение</kwd><kwd>Эквадор</kwd><kwd>макросейсмическая интенсивность</kwd><kwd>сейсмическая опасность</kwd><kwd>сейсмичность</kwd><kwd>сейсмостойкое проектирование</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>About earthquakes.
