Background

• Earthquakes are dangerous threats
• USGS estimates LA 2,000 deaths and 200bn damage
  from 7.8 magnitude quake

Background

• Earthquakes are dangerous threats
• USGS estimates LA 2,000 deaths and 200bn damage
  from 7.8 magnitude quake
• Early warning could minimize suffering
• Activate safeguards in critical operations

A New Seismic Network

• A global distributed seismic network for early
  warning
• Small, inexpensive USB accelerometers
• Analysis done on central servers
• Early warning alerts
• Google maps web interface
