The study shows that the more silica there is in the continental crust, the faster \u2018slow\u2019 earthquakes will occur. Silica lets water flow more easily through the crust, lubricating the fault and making the earthquakes happen sooner. <\/span><\/p>\n<p><span style=\"color: #000000;\">While slow earthquakes are not dangerous, there is a slightly higher risk that a conventional earthquake could start during a slow earthquake.<\/span><\/p>\n<p><a href=\"http:\/\/www.nature.com\/nature\/journal\/v510\/n7505\/full\/nature13391.html\" target=\"_blank\"><span style=\"text-decoration: underline;\">Original research paper<\/span><\/a>\u00a0published in the journal\u00a0<em>Nature\u00a0<\/em>on\u00a0<strong>June 18, 2014<\/strong>.<\/p>\n<p><span style=\"text-decoration: underline;\"><strong>Names and affiliations of selected\u00a0authors<\/strong><\/span><\/p>\n<h4><a style=\"color: #1155cc;\" href=\"http:\/\/www.earth.uottawa.ca\/details.php?lang=eng&amp;id=475\" target=\"_blank\">Pascal Audet<\/a><span style=\"color: #000000;\">, University of Ottawa, Ontario<\/span><\/h4>\n","protected":false},"excerpt":{"rendered":"<p>Every 14 months, a \u2018slow\u2019 earthquake occurs beneath Vancouver island which last for 10 to 14 days; a new study helps explain why some slow quakes happen more frequently than others.
