Prepare Before — Survive During — Recover After

This page is especially recommended for new employees, guests and students, particularly those who are new to California as well as the Lab.

Earthquakes: Not If — When

ECA_80x81Berkeley Lab is very close to the Hayward Fault (it is between the Lab and campus, where it actually runs through Memorial Stadium). Seismologists estimate that there is more than a 60% chance of a damaging earthquake striking our region in the next 30 years. The Lab takes extensive quake-preparedness measures, and many employees also find it prudent to keep individual supplies in their work areas and cars.

   In the event of a quake, drop, cover, and hold on. When the shaking stops, grab essential personal items and find a safe route to the evacuation area outside your building. Do not re-enter the building until cleared to do so by safety officials. Hazardous conditions might exist, and there could be aftershocks.

Please take a moment to view this new LBNL video about what to expect and how to prepare for and respond to a real earthquake.

Earthquake preparedness also explains a lot about our furniture choices (bookshelves with lips or retention chains, file cabinets bolted to the walls, etc.) and office-housekeeping standards (don’t store heavy objects on high shelves; keep the area under your desk clear so you can take shelter there; and avoid storing anything in a way that would block your escape route).

   To help you be prepared at work, at home, and in the car, resources are available from the Earthquake Country Alliance (a good first thing to read is Putting Down Roots in Earthquake Country). Another useful source of readiness tips for all kinds of disasters and setbacks is 72 Hours (named after the minimum amount of time you should be prepared to survive any form of widespread disaster, anywhere, before help arrives).

Wildlands Fire: Are You At Risk?* Are You Ready?

homewildfire_150x143y California’s fire season is typically in late summer through fall, when a heavy growth of plant life is drying out just in time for the “Diablo winds.” However, we must remain aware of fire safety, and report any fires or smokes that we see, at any time of year — especially during the present drought.
   If you live in a vulnerable area, clear defensible space and remove light fuels. The University of California has peer-reviewed advice on how to design and maintain landscape for greater fire safety. See also the Association of Bay Area Governments and American Red Cross websites.

*it’s a trick question . . .
The LBNL site is in a vulnerable area (in 1923, a conflagration moved down what was then an empty hillside where the Lab now stands, and was stopped just short of the campus — not by the puny hand of man so much as by the Diablo winds’ giving way to onshore flow). Many of us also commute through areas that can be affected by wildfires. When fire danger reaches red-flag levels, “hot work” is likely to be suspended, and other bulletins will be issued and precautions put in place as appropriate.

Those who lived and worked in these hills in 1991 — or 1970 — need little reminder…

Co-Existing with Creatures

Picture of doe and fawn Californians can take pride in the environmental consciousness that allows wildlife to flourish close to urban areas. The LBNL site is an attractive home for animals, and also is near or adjacent to large areas of open space with various degrees of wildness.

Deer, turkey, skunks, opossums, raccoons, and even a rattlesnake or two are found here, and with all that prey, at least one mountain lion has been known to drop by for dinner. Keep an eye out for them when on foot (especially around dawn or dusk) and when driving.

One of our smaller wild creatures — the tick — is yet another reason (besides falling and the risk of causing erosion in the rainy season) to stay on the walkways rather than taking hillside shortcuts.

Picture of mountain lion It’s a fact, not a scare story nor an urban-wildlands-interface legend, that at least one mountain lion (cougar) prowls these hills and sometimes hunts on the Lab site. Here is information from the LBNL Protective Services Department and from California Department of Fish and Wildlife on how to minimize the chance of encountering the big cat and what to do if it happens anyway.
