Earthquakes in the Santa Cruz Islands, Solomon Islands

Map of Nenda Island (Solomon Islands) and the recent quakes along with the location of Tinakula
A series of large, relatively shallow (10-50 km) tectonic earthquakes has been occurring in the remote Santa Cruz Islands belonging to the Solomon Islands in the past few days. Since 29 Jan, 13 quakes above magnitude 5 including 3 above magnitude 6 have occurred in clusters in 2 areas. The first (29-30 Jan) and latest (today) cluster of quakes was in an area about 50 km SW of Nata on Nenda Island, the second one (31 Jan) about 50 km ENE of Nenda Island.
The area of the quakes lies at the subduction zone where the Australian oceanic plate dives under the Pacific plate. The subduction process also causes volcanic activity along an arc of island volcanoes. The nearest volcano to the earthquakes is Tinakula, located to the north of Nenda, about 70 km distance from both areas of earthquakes. Tinakula is rarely visited, but one of the most active volcanoes in the world, and often in strombolian activity.

Etna (Sicily, Italy)
: Etna has returned to apparent calm, but it is probably only a matter of days before new activity appears, likely at either Bocca Nuova or the New SE crater. Diffuse ash emissions seem to be occurring from the latter (see image). ...

Divergent plate boundaries in oceans
: Two ocean plates move apart from each other. Hot upwelling mantle material forms magmas that continuously produce new oceanic crust. An ocean widens.
One of the world's most famous volcanoes looming over the City of Naples
: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
