Collection and public Dissemination of near-real time
earthquake shaking information using Azure
George Spyrou , Software Engineer

2. Cloud-Quake

3. The problem:
Minimize the
execution time for
shake maps
calculations in near
real time

4. SMSIM , Fortran programs for simulating
ground motions from earthquakes
• Console application
• Written in Fortran
• Text files as input & output
• Execution time ~ 2 minutes / station
• Independent calculation for each station

5. Architecture
Worker roles Table storage Blob storage Queue storage Management
API

6. Geophysics lab (Linux) Azure cloud
Earthquake queue
Start cloud service

7. Demo

9. Benefits
• Execution time was minimized to < 10 minutes
• Reduced cost because the Cloud-Quake is executed only a few times per month
• No need for maintaining infrastructure

10. Thank you :)
