The voltage delivering 1 watt depends on how many amps are present. We use watts to measure power (P), and amps (I) times volts (E) equals watts. We sometimes see the equation P = I x E written to express this relationship. Let's look at a couple of instances. If we have 1 amp times 1 volt, we'll get 1 watt.
Vailulu'u is a volcanic seamount discovered by geophysicist Rockne Johnson in the Samoa Islands on October 18, 1975.[1] The finding of an active, undersea, hotspot volcano is significant for scientists studying the Earth's fundamental processes.[2]
Within National Marine Sanctuary of American Samoa are two seamounts: Vailuluâu and Malulu. Multibeam map from 2005 showing the Vailuluâu seamount crater. The Nafanua cone can be observed in the middle of the crater. Click image for credit and larger view. Vailuluâu Seamount is located in between Manuâa and Rose Atoll and is the only hydrothermally active seamount within the American Samoa Exclusive Economic Zone. Discovered in 1975 and first mapped in 1999, Vailulu'u is the active volcanic hotspot that created the Samoan archipelago.
