...Currently, plate reconstructions fall into three main categories: (1) “Geologically current” models based on present day plate motions from GPS measurements (Argus and Heflin, 1995), space geodesy e.g. GEODVEL (Argus et al., 2010) or a combination of spreading rates, fault azimuths and GPS measurements e.g. NUVEL-1 (DeMets et al., 1990, 2010) and MORVEL (DeMets et al., 2010); (2) Traditional plate tectonicmodels based on the interpretation of the seafloor spreading record and/or paleomagnetic data to reconstruct the ocean basins, continents and terranes within an absolute reference framework (Scotese et al., 1988; Scotese, 1991; Golonka and Ford, 2000; Schettino and Scotese, 2005; Golonka, 2007; Müller et al., 2008b); (3) Coupled geodynamic–plate models, whichmodel plate boundary locations andmantle density heterogeneity to predict past and/or present plate motions (Hager and O'Connell, 1981; Lithgow-Bertelloni and Richards, 1998; Conrad and Lithgow-Bertelloni, 2002; Stadler et al., 2010)....

...Of the 50 plates, 36 angular velocities were estimated from the GPS velocities in our compilation (mostly ones derived by ourselves), 6 were taken from PB2002 [Bird, 2003] and 8 were taken from MORVEL [DeMets et al., 2010]....

...Our rotation rate for Nazca is significantly slower than the MORVEL estimate, indicating the continued slow-down of the Nazca plate since 0.78 Ma [DeMets et al., 2010]....

...The Bering, Capricorn, Lwandle are part of the MORVEL plate motion model [DeMets et al., 2010], although MORVEL did not have a rotation rate for Bering, which we estimated from the GPS data....

...We therefore adopted the rotation from MORVEL [DeMets et al., 2010]....

...[2] MORVEL is a set of geologically current relative plate angular velocities for 25 major plates covering 97% of the surface of the Earth [DeMets et al., 2010]....

...Differences in angular velocity among the 36 plate pairs are vectors ranging in length from 0.007°Ma−1 to 0.105° Ma−1, with the median difference having a length of 0.053° Ma−1, which corresponds to 5.9 mm a−1 or less along Earth’s surface [DeMets et al., 2010]....

...Thus, in MORVEL the angular velocity of the plates of the Pacific ocean basin (Pacific, Nazca, Cocos) relative to the surrounding continental plates (Eurasia, North America, South America) depend mainly on the plate circuit North America‐Nubia‐Antarctica‐ Pacific [DeMets et al., 2010, Figure 2]....
