List of earthquakes in the Solomon Islands archipelago

Last updated

This is a list of earthquakes in the Solomon Islands archipelago, which includes the nation state of Solomon Islands and Bougainville within Papua New Guinea. Only earthquakes over magnitude 8 are included unless they result in damage and/or casualties. Earthquakes from other regions that were strongly felt in the area are also be included.

Background

The Australian Woodlark, Solomon Sea and Pacific Plates are converging at a rate of 97 mm/yr. [1] The earthquake was a result of interaction between the Australian and Pacific Plates along a subduction zone. Subduction of the Australian Plate has also given rise to volcanoes in the region. This region of the world lies along the Pacific Ring of Fire, where 90 percent of all earthquake and volcanic activity is concentrated here. [2]

Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. The predominant vulnerable building types are adobe walls and informal construction. [3]

Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from weak events detectable only by seismometers, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history. Below, earthquakes are listed by period, region or country, year, magnitude, cost, fatalities, and number of scientific studies.

<span class="mw-page-title-main">2016 Solomon Islands earthquakes</span> Seismic events

On 9 December 2016 at 4:38 a.m. local time, the Solomon Islands region was rocked by an Mww 7.8 earthquake, centred 30 km off San Cristobal Island, about 61 km southwest of Kirakira, the capital of Makira-Ulawa Province. Initially registering magnitude 8.0, later downgraded to 7.8, the temblor prompted tsunami warnings that kept countries surrounding the Coral, Tasman and Solomon Sea on high alert, but was later cancelled. A large aftershock of magnitude 6.9 occurred shortly afterwards. This earthquake was largely felt, waking many residents who later ran to high ground for fears of a potential tsunami. The earthquake killed a child and affected some 34,000 people in Makira, South Malaita and Guadalcanal Island where many had lost their homes or had no access to basic needs. Earthquakes are common in this region, with little or no fatalities. This earthquake is tied with three other magnitude 7.8 earthquakes for the second largest earthquake of 2016. On 17 December, Solomon Islands would be rattled again by a 7.9 magnitude earthquake, this time 54 km east of Taron, Papua New Guinea.
