McKenzie1 proposed that the direction of subduction beneath an island arc will reverse following arc–continent collision. Dewey and Bird2 suggested that such an arc polarity reversal occurred in northern New Guinea; Johnson and Molnar3, however, proposed two alternative models of plate convergence that could explain the observed seismicity. We present here a spatial seismicity study of the Solomon Islands region which has revealed the existence of two juxtaposed Wadati–Benioff (W–B) zones of… 
Microearthquake seismicity in relation to double convergence around the Solomon Islands arc by ocean‐bottom seismometer observation
SUMMARY The Solomon Islands arc area is a complex plate convergence zone. At the North Solomon Trench on the northern side of the arc, it is believed that the Pacific Plate was subducting before
Subduction Polarity Reversal: Induced or Spontaneous?
Subduction polarity reversal (SPR) is the subduction initiation process following the arc‐continent collision. Previous models emphasized the need for the external compressional force to induce it.
Evidence for the formation of a new trench in the western Pacific
Shallow intraplate earthquakes, recently detected along an arcuate zone extending from the northern side of the Caroline Ridge across the western Pacific to the southern end of Kiribati (see cover),
Interrelation of the stagnant slab, Ontong Java Plateau, and intraplate volcanism as inferred from seismic tomography
TLDR
The seismological structure beneath the equatorial Melanesian region, where is tectonically unique because an immense oceanic plateau, a volcanic chain and subduction zones meet, is investigated using data collected from an approximately 2-year-long seismic experiment around the Ontong Java Plateau.
Paleomagnetism and tectonics of Malaita, Solomon Islands
Malaita, in the Solomon Islands, is the emergent expression of the Pacific Province, a geologically distinct suspect terrane which is commonly held to be the margin of the Ontong Java Plateau, a

Subduction without volcanism in the Solomon Islands arc
The Solomon arc lacks subduction-associated volcanism in its eastern part. This anomalous absence arose from the collision of the submarine Ontong Java Plateau with the Solomon arc about 8 m.y. ago
Part 4. Plate boundary evolution in the Solomons region: The Solomons as a non—arc
The Solomon Islands have been described as a fractured island arc (Coleman, 1970) and, more recently, as an arc which has undergone polarity reversal (Karig and Mammerickx 1972) probably within the
A convergent subduction model for the Solomon Islands
Some of the data from seismic studies, gravity, and the distribution of Quaternary surfaces and deposits in the Solomon Islands are consistent with convergent subduction at the margin of the Pacific

Abstract The spatial distribution of earthquakes is described for the Papua New Guinea and Solomon Islands region, using data for the period 1931 to 1970. Most of the seismic activity is concentrated

Studies of the spatial distribution of shallow earthquakes define the present day plate boundaries. In the Papua New Guinea and Solomon Islands region (PNGS) these are well determined and indicate a
