Rocks of the Greater Bay Area and the Stories They Tell

9am-3pm | Lobby, McCone Hall

The Northern California Geological Society ( is a professional organization that promotes education in the earth sciences. We will have rocks and fossils from the Greater Bay Area that illustrate the amazing and multifarious geological processes and events, and a few human ones as well, that have taken place here in our own 'backyard'.


McCone Hall Rocks!

9am-4pm | Floors 1 & 3, McCone Hall

Wander our halls and explore rock and mineral displays (1st and 3rd floors), faculty profile posters, and photos from space. Visit the Berkeley Seismology Lab on the 2nd floor. Take part in activities with professors and students throughout the day!



9am-4pm | Front Entrance, McCone Hall

Come and see our rock display, fondly known to students as McConeHenge, in the front entrance of McCone Hall!


Hands-On Ocean Science Fun!

10am-2pm | Front Entrance, McCone Hall

Drop by McCone Hall and learn about ocean features, coral reefs, ocean circulation, beaches and more, from UC Berkeley Earth and Planetary Science, Geography and Integrated Biology students! Hands-on interactive presentations for all ages. Get your Science@Cal Passport stamped here!


Mapping off the Plane: Bird’s Eye View Maps & More

10am-3pm | 50 McCone Hall

Come check out the Earth Science & Map Library! Geography Dept. graduate student Eve McGlynn has guest-curated a pop-up exhibit featuring non-traditional mapping perspectives of Berkeley and beyond, including birds eye views, aerial views, and more. You can also take the world for a spin with our new digital globe and explore our map collection -- one of the largest in California. This is a stop on the Library Passport!


Student to Student: Open House

10am-3pm | Lobby, McCone Hall

Undergraduates answer questions about student life and the six EPS majors: Atmospheric Science, Environmental Earth Science, Geology, Geophysics, Marine Science, and Planetary Science.



10am-3pm | 2nd Floor, 220 McCone Hall

Discover what can make soil behave like a liquid during an earthquake, find out how your smartphone can help us detect quakes, investigate the behavior of seismic waves, and more! Got earthquake questions? Our graduate students are on hand to answer them, and to share their latest research! Get your Science@Cal Passport stamped here!


Plate Tectonics and Faults in the Bay Area

10am-10:30am | 141 McCone Hall
Presented By: Kathryn Materna, Graduate Student

Welcome to the plate boundary! Most of us are aware that here in the Bay Area, we live in a tectonically active place. Many of us have heard about the San Andreas fault (or maybe have even seen a Hollywood movie about it)! But although the San Andreas fault is the most famous piece of this plate boundary, it's certainly not the only one. What are the major pieces of our tectonic environment? How close is the nearest fault to the places where we live, work, and go to school? Come to this talk to find out more!


A Breath of Fresh Air: The Dramatic History of Atmospheric Oxygen Levels

10:30am-11am | 145 McCone Hall
Presented By: Professor Daniel Stolper

Oxygen, which makes up roughly 20% of our atmosphere, is required by all animals and allows for key reactions, such as the formation of an ozone shield, to occur. Billions of years ago, however, the atmosphere was devoid of this gas. I’ll discuss our knowledge of oxygen, as well as its impact upon the world and the evolution of animals.


Listen to Seismic Noise: A New Tool for Monitoring Volcanoes and Geothermal Field

11am-11:30am | 141 McCone Hall
Presented By: Dr. Taka’aki Taira, Graduate Researcher

The Earth is "humming." Seismometers can capture the sounds of the Earth's hum. It turns out that carefully listening to these tiny whispers of the Earth can tell us what is going on inside, giving us clues about the inner workings of volcanoes and geothermal fields.


California’s Ocean Biological Carbon Pump Bites Back

11:30am-12pm | 145 McCone Hall

Presented By: Professor Jim Bishop and Hannah Bourne, Graduate Student

Join Earth and Planetary Science graduate student Hannah Bourne and Professor Jim Bishop while they describe deployments of deep diving Carbon Flux Explorer robots during a month long study of the biologically rich waters offshore of Big Sur, California. Their study of how biological processes work to move CO2 from the atmosphere to the deep sea included a toothy
biological surprise!


Earth Science Opportunities at Cal

12pm-12:30pm | 141 McCone Hall
Presented By: Geological Association at Berkeley

Geological Association at Berkeley is an organization for undergraduates from all backgrounds who are interested in Earth science. We will discuss our experiences as EPS students, including our research interests and Earth science-related activities that we do within the club. We welcome questions from prospective and admitted students!


Deciphering Volcanoes with Crystal Time-Capsules

12:30pm-1pm | 145 McCone Hall
Presented By: Tanis Leonhardi, Graduate Student

Crystals are time-capsules recording the inner workings of a volcano. Different “clues” are preserved in the crystal depending on its history through the volcanic system. Join us to learn how we use these clues to decipher how and why volcanoes erupt.


Earth’s Metal Heart

1pm-1:30pm | 141 McCone Hall
Presented By: Daniel Frost, Postdoctoral Researcher

At the center of the Earth sits a ball of iron the size of Mars and as hot as the surface of the Sun. Learn how the core affects our lives on the surface, and how we use earthquakes to see what is hidden under 2000 miles of rock.


Tomography Beneath Alaska

1:30pm-2pm | 145 McCone Hall
Presented By: Robert Martin-Short, Graduate Student

How do seismologists use earthquakes to study the interior of the earth? What can we learn from earthquake waves about the geodynamics of Alaska, a region of spectacular earthquakes and volcanoes? A new set of seismometers deployed in the Alaskan region gives us the best images yet of the Alaskan subduction zones.


The Jigsaw Puzzle of the Earth’s Tectonic Plates

2pm-2:30pm | 141 McCone Hall
Presented By: Professor Nicholas Swanson-Hysell

Learn how Earth's continents have moved through time and how Berkeley scientists are working to reconstruct their position. Past positions of continents will be shown on a digital globe.


The Next Geomagnetic Reversal

2:30pm-3pm | 145 McCone Hall Presented By: Professor Bruce Buffet

The strength of the geomagnetic field has been declining since the first direct measurements were made in the 1830s. The rate of decline exceeds the expected rate of decay due to magnetic diffusion, prompting speculations that the Earth may be entering the early stage of a geomagnetic reversal. We examine the evidence for an imminent geomagnetic reversal.


Earthquake Warning: New Technology to Reduce this Harmful Threat

3pm-3:30pm | 141 McCone Hall

Presented By: Professor Richard Allen, Department Chair & Director of the Berkeley Seismology Lab

We can now provide warnings before earthquakes. Hear how we can provide enough warning to take cover under a sturdy table, slow and stop trains, isolate hazardous machinery and chemicals at work, and thereby reduce damage and injuries. Warnings are now being generated in California, and using new smartphone technology they will soon be available around the world.


Largest Submarine Eruption of the Last Century

3:30pm-4pm | 145 McCone Hall Presented By: Professor Michael Manga

Submarine volcanic eruptions may be fundamentally different from those on land. Our understanding of submarine eruptions is limited because it is difficult to directly observe eruptions and challenging to sample deposits from their eruptions. New measurements from the 2012 Havre eruption, the largest of the last century, collected by underwater vehicles are revealing how volcanoes erupt under the ocean.
