Kilauea volcano on the island of Hawaii continues to erupt, creating spectacular footage of lava shooting out of vents and eating cars. While the lava flows are slow moving, and so far no one has been hurt, U.S. Geological Survey scientists were today (May 10) warning that the volcano might erupt explosively, sending large rocks flying through the air.
Teams of undergraduate engineers from UC Davis and nearby colleges and universities will be pulling an all-nighter this weekend, working on using the inspiration or processes of nature to prevent or mitigate natural hazards.
The Center for Bio-mediated and Bio-inspired Geotechnics Design-a-thon runs from 11 a.m. Saturday, April 28 to 3 p.m. on Sunday, April 29 in room 1065, Kemper Hall.
Student teams will select a natural hazard such as fire, flood, earthquake, tsunami or hurricane, and come up with an engineering solution that is affordable, sustainable, has minimal environmental impact and is equitable for all. There will be cash prizes for first, second and third places.
In this month’s episode of Three Minute Egghead, UC Davis graduate student Gabrielle Black talks about collecting samples of ash from neighborhoods burned by last year’s northern California wildfires. The intense heat on a wide range of household items from insulation to electronics may have created new chemical pollutants. Thanks to modern analytic technology, Black plans to search for both known pollutants and new compounds, and compare them to the ashes of burned wild land.

Mexico’s earthquake early warning system may have helped save lives in the Sept. 19 earthquake. Sirens in Mexico City sounded seconds before the earthquake struck the city, giving a brief window to shut down vital infrastructure and evacuate buildings. There was more warning, about 90 seconds, before the larger earthquake that occurred off the coast of Mexico Sept. 8.
A similar system has been tested for the U.S. West Coast including California and is expected to begin limited public operation in 2018.

The flooding in Houston is a reminder of the great damages that floods can cause when the defenses of an urban area are overwhelmed. It is hard to imagine a flood system that could have effectively contained the historic amount of rain that fell on the region—several feet in just a few days. However, these floods are a stark reminder of the increasing vulnerability of urban areas across the world and the need for comprehensive strategies to reduce risk. The evidence is clear that green infrastructure, as defined below, can increase the resiliency of flood management systems and, when managed for multiple services, can reduce flood risk for many people while also promoting a range of other benefits.
The world’s coral reefs are both stunningly beautiful and vital to ocean health, hosting a huge diversity of fish and marine life. And they are, as they always have been, under pressure from periodic natural disasters. However, a coral reef’s ability to recover from unavoidable and often unpredictable natural disasters, like hurricanes and tsunamis, may depend on human activities including fishing and pollution. UC Davis marine biologist Mike Gil is one of the scientists working to understand how reefs recover from natural disturbances in the presence of unnatural, man-made stressors.
The National Science Foundation will award almost $5 million over five years to UC Davis to include the large earthquake-simulating centrifuge at the Center for Geotechnical Modeling as part of the new Natural Hazards Engineering Research Infrastructure program.
Taking lessons from nature and biology into civil engineering is the goal of the new Center for Bio-inspired and Bio-mediated Geotechnics, including the University of California, Davis, Arizona State University, New Mexico State University and the Georgia Institute of Technology, and funded with a five-year, $18.5 million grant from the National Science Foundation.
The center’s director will be Edward Kavazanjian, a professor of civil engineering and senior scientist at ASU’s Julie Ann Wrigley Global Institute of Sustainability. The UC Davis team will be headed by Jason DeJong, professor of geotechnical engineering in the Department of Civil and Environmental Engineering.

Rehabilitated pelicans once covered in oil from last month’s Refugio oil spill in Santa Barbara County were released today (June 12) at Goleta Beach.
Wildlife responders from the UC Davis Oiled Wildlife Care Network and California Department of Fish and Wildlife’s Office of Spill Prevention and Response (OSPR) placed satellite tracking devices on 12 brown pelicans affected by the spill.

Five UC Davis faculty members joined more than 500 top global change scientists in signing a statement that outlines the key environmental issues – from climate change to pollution and population growth — policymakers must address to avoid an approaching global tipping point.
The statement, released today, is a response to a challenge by California Gov. Jerry Brown for scientists to translate their findings into terms policymakers, industry and the general public can understand and begin to address.
The five UC Davis signatories include: parasitology professor Patricia Conrad, environmental science and policy professor Alan Hastings, oceanography professor John Largier, geology professor Geerat Vermeij, and evolution and ecology professor Susan Williams.
