Sentence examples for dip region from inspiring English sources
The authors [24, 25] tried to interpret their data within the McMillan tunneling model of the superconducting proximity effect [9] but experienced large discrepancies, in particular in the dip region.
Therefore, the first significant moment release must start in the down-dip region.
This suggests the possibility that the event is a compound rupture, combining failure of an up-dip region that ruptures similarly to the 1896 tsunami earthquake and a down-dip region that ruptures like the conventional Miyagi-oki large earthquakes.
Because substantial displacement starts around 68 s at Miyako, significant moment release in the up-dip region is considered to start around 35 s (Fig. 4(c)).
Map of the 2011 Tohoku rupture attributes and historic large earthquakes along the up-dip region of the Japan subduction zone.
The up-dip region of the megathrust off northeastern Honshu has small earthquakes with lower frequency characteristics than the down-dip and outer rise regions (Fukao and Kanjo, 1980).
An SSE occurred at the up-dip region of tremor activity in 2010, though there is a few months lag between the occurrence of SSE around tremor hypocenters and the activation of tectonic tremor (Bartlow et al. [2014]).
Clearly the up-dip region did not have strong short-period seismic wave radiation despite having very large slip, as no energy is imaged there in the back-projections.
The 1896 tsunami earthquake appears to have ruptured similarly to the up-dip region in 2011, but the down-dip portion of the megathrust has not had recent large earthquakes and is also lacking in smaller event activity.
That is to say, in the 2011 Tohoku-oki earthquake, significant moment release first occurred in the down-dip region approximately from 20 s to 35 s, which is well consistent with the inversion result of Yagi and Fukahata (2011).
If the significant displacement at Oshika is caused by dislocation around the hypocenter, or in the up-dip region, substantial eastward displacement at Kamaishi must be recorded with several seconds delay.
