This paper investigates the seismicity and rheology of North-Sulawesi subduction zone. Body-wave modeling is used to estimate focal mechanisms centroid depths moderate magnitude (M5–M6.5) earthquakes on North Sulawesi megathrust surrounding region. The slip vectors radiate outward from Sulawesi, indicating motion that incompatible with relative two rigid plates. Instead, observed deformation im...

[1] Multiple mechanisms have been suggested to explain seaward motion of the south flank of Kīlauea Volcano, Hawai‘i. The consistency of flank motion during both waxing and waning magmatic activity at Kīlauea suggests that a continuously acting force, like gravity body force, plays a substantial role. Using finite element models, we test whether gravity is the principal driver of long-term moti...

In this work, we show that the eigenvalues of the problem  (∆2 + V (x) + λ)u(x) = 0 x ∈ Ω u(x) = ∆u(x) = 0 x ∈ ∂Ω are generically simple in the set of C4 regular regions of Rn, n ≥ 2. In fact, we prove that there exists a residual set of regions C4 diffeomorphic to a given Ω such that all the eigenvalues for a supported plate equation are simple.

[1] The Gibraltar Arc in the western Mediterranean consists of the Betic and Rif Alpine chains and the Alboran Sea Basin. Four types of stress indicators (wellbore breakouts, earthquake focal plane mechanisms, young geologic fault slip data, and hydraulic fracture orientations) indicate a regional NW–SE compressive stress field resulting from Africa-Eurasia plate convergence. In some particular...

To determine the exact distribution of tensile stress in a cold rolled strip, evolution caused by lateral uneven velocity outside deformation zone strip is examined. The finite difference method employed to solve problem. Different factors, including width and form amplitude initial on evolution, are analyzed. On one hand, improve calculation speed, “Gaussian” curve proposed fit results calcula...
