Volcano Monitoring: MAUNA LOA ( GG130 ) Geophysics (Deformation via GPS and InSAR, Seismicity, etc. )
2
Mauna Loa deformation patterns and sources
10
2003-2008 Interferometric Synthetic Aperture Radar (InSAR) – derived deformation: Each color cycle represents ½ of a wavelength’s worth of deformation, and for this particular radar system, the wavelength is 5.6 cm
11
Mauna Loa Seismic Monitoring
12
Mauna Loa Seismic Activity for the past year
13
Mauna Loa Earthquake Density for the past 50 years. 0 2.6 7 18 48 126 324
14
Mauna Loa shallow (<5km) Earthquake Activity for the past 50 years.
15
Mauna Loa shallow (<5km) Earthquake Activity for the past 50 years: More shallow earthquakes recently, or better equipment? Earthquake magnitude
16
Mauna Loa shallow (<5km) Earthquake Activity for the past 50 years. Cumulative number of earthquakes
17
To normalize for differences in earthquake detection thresholds, we can count earthquakes scaled by their relative energy release. Earthquake energy scales by 10 ^(3M/2) (where M is the magnitude). So, a magnitude 4.0 earthquake has the equivalent energy of 10 ^(3/2) ≈ 32 magnitude 3.0 earthquakes
