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. Researchers can use acoustics to study underwater volcanoes. • Seismic activity (earthquakes and tremors) always occurs as volcanoes awaken and prepare to erupt and are a very important link to eruptions. Some volcanoes normally have continuing low-level seismic activity, but an increase may signal a greater likelihood of an eruption. The types of earthquakes that occur and where they start and end are also key signs. Volcanic seismicity ha…
