More volcanic activity in Solomons quake zone

The National Disaster Management Office in Solomon Islands says volcanic activity has increased on an island in Temotu province since the magnitude 8.0 earthquake two days ago.

Sipuru Rove says the uninhabited island of Tinakula, which is about 50 kilometres north of Lata, has being making loud and strange sounds.

He says help and information is needed from technical experts to assess the risk posed to the local community by the volcano as they are worried an eruption could be near.
"The volcanic activity on one of the islands that is off Lata is alarming at the moment. And this will really require scientific special people to assist us in assessing this volcanic activity which is beginning to be abnormal."
Sipuru Rove says there are also significant aftershocks which meant a plane with supplies and medical staff couldn't land and was forced to return to Honiara.

What caused the Solomon Islands earthquake & tsunami?

The deadly earthquake and tsunami that hit the Solomon Islands today struck along a subduction zone, the same geologic setting responsible for the world's most powerful earthquakes.

In a subduction zone, two of Earth's tectonic plates meet and one slides beneath the other into the mantle, the deeper layer beneath the crust. The Solomon Islands sit above the collision between the Australia and Pacific plates. In the region of today's magnitude-8.0 earthquake, the Australia plates dives beneath the Pacific plate toward the east-northeast at a geologically speedy 3.7 inches (94 millimeters) per year, according to the Incorporated Research Institutions for Seismology (IRIS).

The earthquake hit at a depth of 17.8 miles (28.7 kilometers) and was the second-largest earthquake in the Solomon Islands region in almost 40 years, IRIS said in a statement. Several aftershocks followed; the largest measured magnitude 6.6, according to the U.S. Geological Survey (USGS).

The tsunami generated by the quake, reported as 3 feet (0.9 meters) in height, hit villages on Santa Cruz Island, destroying structures and homes, according to news reports. A tsunami watch was issued for Australia, Indonesia and New Zealand, but not for the rest of the Pacific, according to the West Coast and Alaska Tsunami Warning Center.

Small tsunami hits Solomons after major quake

© Hugh Gentry/ReutersThe Pacific Tsunami Warning Centre in Hawaii has issued an alert after a quake off the Solomon Islands.
Sydney - A small tsunami hit the Solomon Islands on Wednesday after a major 8.0 magnitude undersea earthquake sparked a tsunami warning for several South Pacific island nations and placed many more nations including Australia and Indonesia on alert.

The quake struck at a very shallow depth of only five km (three miles) and was located 340 km (211 miles) east of Kira Kira in the Solomons, the Pacific Tsunami Warning Center in Hawaii said.

The center said a tsunami measuring 0.9 metres (three feet) hit the Solomons following the quake.

The Solomon Islands Broadcasting Corporation cited a witness who said water was covering an airstrip in Lata, in Temotu province, but there were no immediate reports of damage or casualties.

Solomon Islands police in the small town of Kira Kira, on San Chrostobal island, said they felt the quake, but there were no reports of any damage from the quake or a tsunami.

"We felt the shock. We have warned people to get to higher ground," said local police officer Samuel Tora.

The tsunami warning center gave arrival times from a few minutes to several hours to island nations around the South Pacific.

The warning was issued for the Solomon Islands, Vanuatu, Nauru, Papua New Guinea, Tuvalu, New Caledonia, Kosrae, Fiji, Kiribati, and Wallis and Futuna islands.
