WebAncient people believed that volcanoes were under the control of the gods. In fact, the word volcano comes from Vulcan, the Roman god of fire. Currently there are about 1,500 potentially active volcanoes worldwide. 169 of these are in the United States. Volcanic eruptions can cause death and widespread devastation. WebUSGS scientists collect data using an assortment of aerial (aircraft), orbiting (satellites) and handheld sensing instruments, such as thermal imaging cameras. Once the data is collected, it can be analyzed and used to predict future eruptions. "There are many advantages to taking measurements using a handheld thermal camera," said Steve ...

(Answer: False. While no one can detect exactly when a volcano will erupt, we can usually determine that one is due to occur.) Lesson Summary Assessment WebThe acoustic signal from seismic waves produced by conversion of seismic energy is called a Tertiary wave (or T-wave) that can be detected by hydrophones at great distances. The T-waves have frequencies of 4 to 50 Hz and are a significant source of ambient noise in this frequency band.
