Crustal deformation associated with an M8.1 earthquake in the Solomon Islands, detected by ALOS/PALSAR

Characteristics on fault coupling along the Solomon megathrust based on GPS observations from 2011 to 2014

“…Miyagi et al . [] found large slip on the megathrust near the extension of the WLP‐AUP‐PAP triple junction (Figure b), with maximum slip of ~10 m around Ranongga Island, close to the centroid reported by the global centroid moment tensor (CMT) (Figure b) [ Miyagi et al ., ]. Miyagi et al .…”

“…Miyagi et al . [] further suggested that this slip pattern results from the strong coupling associated with the rugged bathymetry along the plate boundary.…”

“…This geometry is identical to that of the 2007 M w 8.1 Solomon earthquake from Miyagi et al . []. The Green's function is computed based on dislocations in a homogeneous elastic half space [ Okada , ] with Poisson's ratio of 0.25.…”

“…It remains uncertain whether the Solomon megathrust behaves predominately aseismic or not [ Cooper and Taylor , ]. The 2007 M w 8.1 earthquake revealed the coupled nature at least along a certain segment on the megathrust [ Miyagi et al ., ]. Three years later, the 2010 M w 7.1 earthquake near the hypocenter of 2007 earthquake and produced a damaging tsunami [ Newman et al ., ].…”

SAR interferometry and optical remote sensing for analysis of co-seismic deformation, source characteristics and mass wasting pattern of Lushan (China, April 2013) earthquake

“…The Bam (2003, Iran) and L'Aquila (Central Italy, 2009) earthquakes were studied for co-seismic deformation using ENVISAT ASAR data by Stramondo et al (2005) and Papanikolaou et al (2010) respectively. Miyagi et al (2009) used ALOS PALSAR data to derive the co-seismic deformation of the Solomon islands earthquake (2007). They also used the DInSAR derived displacement values to derive the fault plane solution using elastic dislocation modelling.…”
