Getting a sinking feeling?

Sinkholes are created when underground rocks are eroded or dissolved by groundwater. Certain rocks are more susceptible than others to this kind of dissolution, and we have a pretty good idea of where they are. Here is a map showing areas of karst, areas susceptible to sinkholes, in the U.S.

Could a tsunami hit US beaches?

Yes. According to tsunami deposit records left in Hawaii, Alaska, and the U.S. West Coast. U.S. beaches are vulnerable to tsunamis generated all around the Pacific Rim - anywhere there is a subduction zone or unstable shelf - which includes all of the U.S. West Coast and Hawaii. Tsunamis have been less frequent on the U.S. East coast and the Gulf coast.

But, can I see my house?

That depends upon the remote-sensing platform (i.e., satellite, aircraft).  However, you may be able to identify your town. The surface of the Earth is changing rapidly, at local, regional, national, even global scales, with significant repercussions for people, the economy, and the environment. Remote sensing satellites and aircraft monitor the Earth providing information that is broad, precise, impartial, and easily available.

Will a landslide bring you down?

Hopefully not! However, landslides occur in all U.S. states and territories, and cause $1-2 billion in damages and more than 25 fatalities on average each year. Falling rocks, flows, and slides are among the most common and sometimes deadly hazards, yet there is still much to learn about how and why they happen.

January is Hawaii's Volcano Awareness Month. Where can I learn about VOG and other volcanic hazards?

On the Big Island of Hawaii, Kilauea has been continuously erupting since January 1983! Besides the hazard posed by flowing lava, residents and visitors alike need to be aware of the hazard posed by volcanic smog (VOG).
