Editing Yokohama (section)

===Geology===
The city is very prone to natural phenomena such as [[earthquakes]] and [[tropical cyclones]] because the island of [[Honshū]] has a high level of seismic activity, being in the middle of the Pacific [[Ring of Fire]].

Most seismic movements are of low intensity and are generally not perceived by people. However, Yokohama has experienced two major tremors that reflect the evolution of [[Earthquake engineering]]: the [[1923 Great Kantō earthquake]] devastated the city and caused more than 100,000 fatalities throughout the region,<ref name=":5">{{cite web |title = Collection of 1923 Japan earthquake massacre testimonies released |url = http://www.hani.co.kr/arti/english_edition/e_international/601938.html |website = hani.co.kr |access-date = January 8, 2016 |date = September 3, 2013 |archive-date = March 4, 2016 |archive-url = https://web.archive.org/web/20160304133217/http://www.hani.co.kr/arti/english_edition/e_international/601938.html |url-status = live }}</ref> while the [[2011 Tōhoku earthquake and tsunami]], with its epicenter on the east coast, was felt in the locality but only material damage was lamented because most buildings were already prepared to withstand them.<ref>{{cite web|title = FNN Remembering 3/11: Yokohama station and surrounding areas at time of earthquake occurrence.|url = http://www.fnn-news.com/en/311/kanto/articles/201103110039.html|website = fnn-news.com|access-date = January 10, 2016|archive-date = March 5, 2016|archive-url = https://web.archive.org/web/20160305015603/http://www.fnn-news.com/en/311/kanto/articles/201103110039.html|url-status = live}}</ref>
