“…The W phase, a distinct long-period (100-1000 s) phase arrives before the S phase and can be used for rapid and robust determination of great earthquake source parameters (Kanamori and Rivera 2008;Duputel et al 2011). This W-phase inversion algorithm is used to estimate the magnitudes, the centroid locations, and the mechanisms of the 2018 Swan Island earthquake (Mw7.6).…”

“…In this study, at first, the source model of the 2018 large Swan Island earthquake is determined by using the W-phase inversion (Kanamori and Rivera 2008) and the scaling relationship (Blaser et al 2010). Then, the tsunami hazard at Puerto Cortes in the northern coast of Honduras is evaluated from realistic fault models based on the fault models of the 2018 large Swan Island earthquake.…”

In 2018, a large earthquake (Mw7.6) occurred in the Swan Island Fault zone at the northwest boundary of the Caribbean plate. This earthquake generated a small tsunami of 20 cm. However, Puerto Cortes in Honduras is located close to the Swan Island Fault zone. Evaluation of tsunami hazard at Puerto Cortes due to large earthquakes along the fault zone is important. We first estimated the fault parameters of the 2018 Swan Island earthquake using W-phase inversion technique. Then, the moment magnitude of 7.6, the fault length of 134 km, the fault width of 24 km, and the slip amount of 5.1 m were estimated. In addition to those estimates, a small fault dimension of the earthquake, 40 km × 20 km, with a slip amount of 20.8 m was considered. Those two fault models were used to compute tsunami inundation at Puerto Cortes. The tsunami computed from the small fault inundated a large area in Puerto Cortes including the port area. The effect of co-seismic horizontal displacement of ocean floor also enhanced the tsunami inundation at Puerto Cortes. Those results indicate that preparation for future tsunami hazard in Puerto Cortes is important although no significant tsunami was generated historically.

“…The first one is formulated in the time domain and based on higher-order shape functions defined using Gauss-Lobatto-Legendre or Chebyshev points (Patera 1984). This method is first proposed to solve problems in fluid dynamics and then extended to three-dimensional time-domain wave-propagation analysis (Komatitsch and Tromp 1999;Komatitsch et al 2000Komatitsch et al , 2001Komatitsch et al , 2002Komatitsch et al , 2004Komatitsch et al , 2005Morency and Tromp 2008). The other SEM is formulated in the frequency domain, which employs the frequency-dependent dynamic-shape functions obtained from the exact solution of governing differential equations and Fast Fourier Transforms (FFT).…”

The paper presents a methodology to analyze plane frame structures using the Spectral Element Method (SEM) with and without considering Soil-Structure Interaction (SSI). The formulation of spectral element matrices based on higher-order element theories and the assemblage procedure of arbitrarily oriented members are outlined. It is shown that SEM gives more accurate results with much smaller computational cost, especially at high frequencies. Since the formulation is in the frequency domain, the frequency-dependent foundation impedance functions and SSI effects can easily be incorporated in the analysis. As an example, the dynamic response of a plane frame structure is calculated based on the Finite Element Method (FEM) and SEM. FEM and SEM results are compared at different frequency bands, and the effects of SSI on the dynamic response are discussed.
