Solid Earth: Essential List

1
Solid Earth Essential List

• Pore fluid pressure (sed and rock)
• Temperature
• Seismic structure - Vp, Vs, anisotropy, Q, as
  functions of (x,y,z,t) and wavelength/frequency
• Rheology geotechnical properties (elastic,
  viscous, etc.)
• Fluid Gas Chemistry
• Stress Tensor - ?1, ?2, ?3, SHmin, SHmax
• Permeability
• Storage (poro-elastic properties)

2
Solid EarthImportant but either less essential
or better addressed by other means (Observatories
or logging)

• Seismicity
• active induced micro-earthquakes (e.g,
  hydrofracture)
• Passive micro-earthquakes
• Porosity (heterogeneity, scale dependence, )
• Fluxes of fluid, gas, solutes, heat, momentum
• Strain transients (tilt, strain tensor)
• Rock sampling (precisely located undisturbed
  cores)
• Electrical structure
• Thermal conductivity
• Rock fabric - wall structure
