Earthquakes, volcanoes, landslides and tsunamis are all seismic hazards that happen worldwide. Hot spots are those places where tectonics, volcanic activity, sea floor spreading and quakes are affected by deep, hot magma rising, plates moving and pressures beneath the Earth's crust. These all contribute to...
What are seismic hot spots?
By: Blaise Pascal
The Earth's surface is comprised of numerous major and minor plates which are continuously in motion. This movement causes volcanic and seismic activity at the borders of the plates and accounts for the majority of all volcanic activity on the planet. However, there are areas...

Volcanic fumaroles can offer scientists useful insights into events occurring within the Earth. These structures frequently occur in association with volcanic activity. Exploring the “anatomy” of a fumarole may present significant dangers, yet the process often provides a way to monitor important environmental changes...
