Immense damage from the 1989 Loma Prieta earthquake that hit the San Francisco Bay Area of California can be seen above. If you live along an active fault – in California, or anywhere major quakes can happen – right now is the time to prepare for a large earthquake!
Why It Matters
- Southern California, south of the San Gabriel Mountains, is over 100 years overdue for a major earthquake.
- There is a 2 in 3 chance that the San Francisco Bay Area will experience a 6.7 or higher quake in the next 30 years.
- Stress is building along the San Andreas Fault, and will continue to build until that stress is released by an earthquake.
- In 1868, a 6.8 caused extensive damage along the Hayward Fault.
- In 1906, a 7.9 along the San Andreas Fault had a 300 mile surface rupture.
- The Loma Prieta earthquake in 1989 was a 6.9.

- How do geologists learn the frequency and magnitude of earthquakes along a fault?
- Some developing countries use earthquake codes from the U.S., but buildings collapse in a quake. Does this mean necessarily that the same types of buildings will collapse in the same magnitude earthquake in the U.S.?
- What can result from earthquakes that cause damage and deaths?
- Why might communities have difficulty surviving for the first 2 to 3 years after an earthquake?
- What are the seven steps you need to follow to prepare for an earthquake?
