LOS ANGELES ASTRONOMICAL SOCIETY BULLETIN
July SpeakerRosaly Lopes Volcano on Earth, Io, & Titan
July 11, 2005
July 2005
Volcanoes are common throughout the Solar
System and are a major force shaping planetary
surfaces. Volcanic eruptions are one of nature's
most awesome spectacles and can range from gentle
effusions of lava to catastrophic explosive events
such as the eruption of Mount St. Helens in 1980.
As we explore other worlds, we come across forms
of volcanism much different from what we see on
Earth today, and others that are surprisingly similar.
This talk will focus on the diversity of manifestations of planetary
volcanism, with particular emphasis on Jupiter's moon Io, where we
find more than 150 active volcanic centers and the hottest lavas known.
Recent results from the Cassini mission will also be discussed. Cassini
is exploring the Saturn system, where many of the moons show evidence
or ice volcanism.
Dr. Rosaly Lopes is a Principal Scientist at the Jet Propulsion Laboratory,
Lead Scientist for the Geophysics and Planetary Geosciences
Group, and Investigation Scientist for the Cassini radar instrument.
She has written numerous academic papers, as well as popular-level
publications. She is the editor of "Volcanic
Worlds: Exploring the Solar System Volcanoes
(Praxis-Springer, 2004) and author of
"The Volcano Adventure Guide (Cambridge
University Press, 2005), the first travel
guidebook to volcanoes. She is a member of
several scientific societies and a Fellow of the
Explores Club. Rosaly started working in volcanology
while a graduate student in London,
England, and has traveled to many of the
world's most fascinating volcanoes.
Her work
on planetary volcanism has included Mars,
Io, and Titan. She worked for several years
on the Galileo mission studying the active
volcanoes of Jupiter's moon Io, where she discovered
71 new active volcanoes. She currently
works on the Cassini mission studying ice volcanism on Titan,
Saturn's largest moon.

JPL Stories - Volcano Adventures on the Earth and Planets
Presented by Rosaly Lopes, Principal Scientist in the Earth and
Space Sciences Division and Lead Scientist for Geophysics and Planetary
Geosciences
June 16, 2005
Come hear the story of researching volcanoes -- from the very hot volcanoes
of Io to the cryovolcanic flows of Titan. Rosaly will talk about her
research on planetary volcanoes, done from a safe distance, to some
close calls on erupting volcanoes on Earth.
