While this might sound simple, however, landslides have many triggers, ranging from heavy precipitation to snowmelt, to seismic shaking, and come in many sizes \u2013 ranging from smaller, shallow slides to massive, deep-seated movements in rock. Here in Oregon, we regularly encounter various types, including shallow translational slides, deep-seated rotational slides, earthflows, and dramatic rockfalls.<\/p>\n\n\n\n<h5 class=\"wp-block-heading has-custom-blue-color has-text-color has-link-color wp-elements-e43c4fb7d76ef28a490edfa3f61a8014\"><strong>What Triggers These Earth Movements?<\/strong><\/h5>\n\n\n\n<p>Three main culprits typically set the stage for landslides:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Water<\/strong>: Rain or snowmelt seeping into the ground can cause soil and rock to buoyant, weakening the strength of soil and rock.<\/li>\n\n\n\n<li><strong>Erosion<\/strong>: Particularly active near rivers and coastlines, where water gradually undermines slope stability<\/li>\n\n\n\n<li><strong>Earthquakes<\/strong>: A special concern in the Pacific Northwest, where the potential for a major Cascadia Subduction Zone earthquake could trigger widespread landsliding<\/li>\n<\/ul>\n\n\n\n<h5 class=\"wp-block-heading is-style-default has-custom-blue-color has-text-color has-link-color wp-elements-fc5b5f10a7092bdf47314edce679544d\"><strong>Nature&#8217;s Warning Signs<\/strong><\/h5>\n\n\n\n<p>While landslides can sometimes catch us off guard, they often leave clues:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deep cracks appearing in the ground (tension cracks)<\/li>\n\n\n\n<li>Unusual ground movement \u2013 sinking at the top of slopes and bulging at the bottom<\/li>\n\n\n\n<li>Trees taking a unexpected lean or showing curved trunks<\/li>\n\n\n\n<li>Changes in vegetation patterns, especially the appearance of water-loving plants<\/li>\n\n\n\n<li>Structural deficiencies, such as sticky doors or transverse cracks<\/li>\n<\/ul>\n\n\n\n<h5 class=\"wp-block-heading has-custom-blue-color has-text-color has-link-color wp-elements-1f95814ec9ead61cc742a30bd1d71d05\"><strong>Taking Action: How We Manage Landslide Risk<\/strong><\/h5>\n\n\n\n<p>Understanding and managing landslide risk is at the core of our research.
