‘This is the worst disaster the nation has seen’

Dozens Dead or Missing, Thousands Homeless in Solomons Flooding

Flash flooding has claimed at least 6 lives, left dozens missing and more than 10,000 homeless in the Solomon Islands’ capital Honiara (population: ∼ 70,000), prompting authorities to declare a state of emergency.

“This is the worst disaster the nation has seen,”  said the  Solomon Star newspaper.

Extreme Rain Events lasting for about a week  caused the main Matanikau River to burst its banks, sweeping away entire communities. The rain and flooding continue.

A spokesperson from the National Disaster Management Office said the office will assess the damage to map out the cost but said it will be costly.

“Homes were swept away by flash floods, lives were lost, properties damaged but the real extent of the damage is still sketchy,” the spokesman said.

“Matanikau River caused significant damage and there are other reports from other parts of Guadalcanal that were hard hit on Thursday.”

He said the Guadalcanal plains were also affected.

“Reports from those areas were that homes were flooded and food gardens wiped out.

“Lunga River also unleashed her might yesterday affecting a lot of residents in Lunga.”

The old one-lane Mataniko bridge is gone. On the Guadalcanal plains, hundreds of villagers headed for the hills last night as flooding took away  homes. This is the worst disaster the nation has seenSolomon Star News

Powerful Aftershocks Still Striking Solomon Isles

Posted by feww on January 6, 2010

Aftershocks Continue to Strike Solomon Islands

Seven fishermen from Viru in the Western Province were reported missing amid continuing aftershocks, the Solomon Star newspaper reported. The seven have not been seen since Monday’s mainshock and tsunami.

As of posting, 8 more aftershock Measuring greater than M5.0 have struck near the epicenter of the mainshock that occurred on January 4. See:

The largest of these aftershocks measured up to 7.2Mw.

The Solomon Islands region, which comprises a section of the Pacific Ring of Fire, is particularly prone to earthquakes because of the above average rate of convergence of the Australia and Pacific tectonic plates in the region.

The down-going slab of the Australian plate is overridden by leading edge of the Pacific Plate at a rate of about 10 cm/yr near the location where the shocks occurred.

As the subducting plate is forced into the earth’s mantle, the more brittle areas of the crust is crushed resulting in the release of stress energy—earthquakes.
