Table 1 List of plates and analysis methods

From: The present-day number of tectonic plates

Worldwide S1 52 4 9,807,692 Bird (2003) Classical analysis using SFS, fault and earthquake locations, fault displacements, etc.
Worldwide S1, S2 22 6 659,803 See Additional file 1: Table S1 Ditto. Tarim Basin is not counted here but is counted in Additional file 1: Table S6.
SCSZ S3 17 17 6702 Bird and Rosenstock (1984) 81 fault motions from geological estimates. Relative block motion from vertical fault strikes. Most ages are Pliocene—Quaternary.
SCSZ S3 4 4 16,120 McCaffrey (2005) 23 plates. Most of the area is covered by Bird and Rosenstock (1984). 3046 GPS velocities, 110 slip vectors, 132 slip azimuths. Plate boundaries fixed by known faults. GPS vel. misfits are 1 mm/year.
Basin and range S4 31 31 862 Hammond et al. (2011) 60 plates. 307 sites occupied by 57 GPS receivers. In addition, there were six continuous GPS sites
of the PBO. Elastic strain close to perimeter is modeled. Boundaries are obtained from mapped faults.
Basin and Range Mohawk 1 1 25,748 Hammond and Thatcher (2007) Mohawk has 14 GPS stations measured over a 4-year period. Campaign sites have a 1σ velocity uncertainty of 0.8 mm/year, and for continuous sites, it is 0.4 mm/year.
Mediterranean S5 11 6 565,570 Reilinger et al. (2006) “Substantial areas of continental lithosphere … show coherent motion with internal deformations below 1–2 mm/year.”
Tibet S6 11 0 269,331 Thatcher (2007) 5 plates with 233 GPS sites allowed rotation pole calculation. Another set of 6 plates with 111 GPS sites had translations calculated, equivalent to rotation about a pole 90° away.
Tien Shan S7 5 5 25,748 Meade and Hager (2001) Block model developed from known fault segments with 8 blocks. Elastic deformation allowed close to plate edges.147 GPS sites. Mean residual velocity ~1.3 mm/year.
New Zealand S8 5 5 27,587 Wallace et al. (2004b) GPS, earthquake, and geological slip rates used to demonstrate that the tectonic block model works well for the boundary zone.
SCSZ S9 17*    Meade and Hager (2005) 439 GPS stations. Mean uncertainty 1.45 mm/year. 24 blocks modified from Jennings (1994) fault map. Elastic deformation allowed near faults.
