Key characteristics of a range of earthquake signals, including frequency spectra and response patterns, are identified, with particular focus on the swarm of earthquakes on 23 December 2011, including four earthquake events greater than magnitude 5.0 on the Richter scale. The findings indicate that the response of the isolators and the superstructure was essentially elastic for the events analyzed during this period. Accelerations measured above and below the isolators were similar, indicating that the behavior of the devices resembled that of rigid blocks. No significant rocking or torsional motion of the building was observed.<\/jats:p>","DOI":"10.1193\/021513eqs027m","type":"journal-article","created":{"date-parts":[[2013,10,17]],"date-time":"2013-10-17T10:06:57Z","timestamp":1382004417000},"page":"383-400","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Christchurch Women's Hospital: Analysis of Measured Earthquake Data during the 2011\u20132012 Christchurch Earthquakes"],"prefix":"10.1002","volume":"30","author":[{"given":"Akshay","family":"Sridhar","sequence":"first","affiliation":[{"name":"University of Canterbury Christchurch 8041 NZ"}]},{"given":"Adam","family":"Kuang","sequence":"additional","affiliation":[{"name":"University of Canterbury Christchurch 8041 NZ"}]},{"given":"Joseph","family":"Garven","sequence":"additional","affiliation":[{"name":"University of Canterbury Christchurch 8041 NZ"}]},{"given":"Stefanie","family":"Gutschmidt","sequence":"additional","affiliation":[{"name":"University of Canterbury Christchurch 8041 NZ"}]},{"given":"J.
