Earthflows have a characteristic "hourglass" shape. The slope material liquefies and runs out, forming a bowl or depression at the head. The flow itself is elongated and usually occurs in fine-grained materials or clay-bearing rocks on moderate slopes and under saturated conditions. However, dry flows of granular material are also possible.

When it comes to talking to others, especially when explaining science, the key is consequences outweigh precision. You should always be honest, tell the truth, but don't sweat the small stuff. People care about relatability, not the mundane. Knowing what information isn't worth sharing is hard. There are professionals out there who can help. Like me.

Translational slide: In this type of slide, the landslide mass moves along a roughly planar surface with little rotation or backward tilting.

Rotational slide: This is a slide in which the surface of rupture is curved concavely upward and the slide movement is roughly rotational about an axis that is parallel to the ground surface and transverse across the slide.

The ocean is a beautiful, dynamic, and sometimes dangerous place. Unsurprisingly, this is probably why a lot of USGS researchers spend their entire careers studying it. In celebration of National Ocean Month, we thought it would be a good time to dive in and feature ten ocean field sites you’ve got to “sea” to believe.

The May 18, 1980, eruption of Mount St. Helens was historic and fundamentally changed how we see volcanoes. For those who lost family and friends, homes, and their livelihoods, it was an unimaginable tragedy. For others around the world, the eruption was an exciting curiosity, an experience they could share with their kids and grandkids.

Although it may seem like it’s solid beneath your feet, the Earth is a dynamic structure. The surface is constantly moving. Different parts of the planet move in different ways and at different time scales. The USGS studies these sometimes subtle, yet sometimes dramatic movements to help keep us safe.
