USGS Earthquake Science is Helping Inform Critical Decisions
- "Did an earthquake just occur, where was it centered and how large was it?"
- "What communities and structures are vulnerable?"
- "What size and frequency of aftershocks are expected?"
ARCHITECTS AND ENGINEERS
- "What buildings are vulnerable and might need renovating?"
- "Are building codes and standards appropriate for a given area?"
BUILDERS AND DEVELOPERS
- "What's the earthquake hazard where major infrastructure investments are being considered?"
- "What's the likelihood of a damaging earthquake where I live and how should I prepare for it?"
- "What is needed to protect lives and property nationwide?"
The East is Not Immune to Earthquakes
