===Earthquakes===
The Pyrenees and Catalonia have frequent and sometimes destructive earthquakes — the largest in recorded history being the [[Catalan earthquake of 1428]] with an estimated magnitude of IX on the [[Medvedev–Sponheuer–Karnik scale|MSK]] scale, equivalent to 6.0–6.5 on the [[Richter magnitude scale]].<ref name="igc1">[http://www.igc.cat/web/gcontent/en/sismologia/igc_sismologia_sismicitat_seglexx.html Maximum felt intensities in Catalonia during the XX century] {{Webarchive|url=https://web.archive.org/web/20070708134429/http://www.igc.cat/web/gcontent/en/sismologia/igc_sismologia_sismicitat_seglexx.html |date=2007-07-08 }}, Table I: Approximative correspondence between the magnitude (Richter) and the intensity (MSK) felt in the epicentral area.</ref><ref name="igc2">[http://www.igc.cat/web/gcontent/en/sismologia/igc_sismologia_sismicitat_mapa400m.html Sismicitat a Catalunya] {{Webarchive|url=https://web.archive.org/web/20070708134151/http://www.igc.cat/web/gcontent/en/sismologia/igc_sismologia_sismicitat_mapa400m.html |date=2007-07-08 }}, Institut Cartogràfic de Catalunya, 1999. {{in lang|ca}}</ref> However, earthquakes whose epicentres are inside Andorra tend to be smaller than magnitude&nbsp;2.<ref name="igc2"/><ref name="igc3">[http://www.igc.cat/web/gcontent/ca/sismologia/sismescomact/llistats/locals/2001/juliol/locals.html Terratrèmols locals de Juliol de 2001] {{Webarchive|url=https://web.archive.org/web/20080607205626/http://www.igc.cat/web/gcontent/ca/sismologia/sismescomact/llistats/locals/2001/juliol/locals.html |date=2008-06-07 }}, Institut Geològic de Catalunya. {{in lang|ca}}</ref> An earthquake of magnitude 4.2 on 5 October 1999 in nearby [[Bagnères-de-Luchon]] (France) was widely felt in Andorra, causing public alarm.<ref name="vwc1">[https://archive.today/20130115233329/http://www.vilaweb.cat/www/noticia?p_idcmp=1114585 El terratremol espanta tot Andorra, pero no causa danys], ''VilaWeb.cat'', Maresma i Associats, SL. 1999-10-05. {{in lang|ca}}</ref> The Andorran Government has studied the possibility of a damaging earthquake in Andorra.<ref name="sost1"/>
