(1) When an oceanic tectonic plate cracks
doi:10.1038/490183a
The recent two earthquakes in Indonesia occurred in the interior of oceanic plates rather than a plate boundary. Theses exceptional earthquakes raised questions to classic seismology .
Nature (Letter)
(2) April 2012 intra-oceanic seismicity off Sumatra boosted by the Banda-Aceh megathrust M. Delesclause et al
doi:10.1038/nature11520
The earthquakes in Indonesia in 2012 seemed to be a continuation of the earthquakes in 2004 and 2005 that caused the plate deformation between India and Australia.
(3) En échelon and orthogonal fault ruptures of the 11 April 2012 great intraplate earthquakes
H. Yue, T. Lay, & K. Koper
doi:10.1038/nature11492
The seismic wave analysis revealed that there were four-fault ruptures lasting about 160 seconds.
(4) The 11 April 2012 east Indian Ocean earthquake triggered large aftershocks
worldwide
F. F. Pollitz, R. S. Stein, V. Sevilgen & R. Burgmann
doi:10.1038/nature11504
The global aftershocks after the 2012 east Indian Ocean earthquake were located along the four lobes of Love-wave radiation.

(5) New arctic research vessel ready to make a splash
doi: 10.1126/science.338.6104.183
Good news for polar researchers! NSF has a new research ship for Bering Sea research. Science (Perspectives)
(6) A golden spike for planetary science
doi: 10.1126/science.1228328
The comments about Dawn mission: exploring Vesta, the second most massive asteroid in the solar system, tell us the evolution of planets and distribution of water. In situ measurements confirmed previous logical interpretation.
(7) Downsizing the deep biosphere
doi: 10.1126/science.1229296
Regarding the argument about microbial biomass beneath the ocean floor. 1 or 10 to 30%? There are so many factors that need to be investigated for a better estimation (e.g. temp., space and energy availability etc).
(8) Seeing is believing
doi: 10.1126/science.1228953
The central Andes sits on the largest active magma body, and the magma is rising underneath.
(9) An ancient core dynamo in asteroid Vesta
R. R. Fu et al
doi: 10.1126/science.1225648
The comparison between Vesta and a meteorite discovered in Antarctica in 1981 has revealed that Vesta formed a liquid metallic core.
(10) Elemental mapping by Dawn reveals exogenic H in Vesta’s regolith
T. H. Prettyman et al.
doi: 10.1126/science.1225354
Vesta was elementally mapped, and it revealed that the high concentration of hydrogen around the equator is caused by accumulations of chondrites.
(11) Pitted Terrain on Vesta and implications for the presence of volatiles
B. W. Denvei et al.
doi: 10.1126/science.1225374
Pitted terrain on Vesta seems to be formed from the degassing of volatile bearing materials.
