Cyclone PAM: “Entire communities have been blown away”

Links sent by Tom C.

Super Cyclone PAM probably caused “one of the worst disasters ever seen in the Pacific”

Up to 90 per cent of homes in Vanuatu’s capital Port Villa has reportedly  been seriously damaged by Super Cyclone PAM, leaving “most” of the population homeless, with no information available yet as to the fate of more than 33,000 people who live on the extremely vulnerable outer islands. 

“This is likely to be one of the worst disasters ever seen in the Pacific,” said Oxfam Country Director in Port Vila, Colin Collet van Rooyen.

“Entire communities have been blown away.”

Cyclone PAM made a direct hit on Vanuatu island late Friday, plowing through the archipelago of 65 islands [pop. ~ 270,000] with supercharged force.

“With more than 250,000 people at risk from the severe tropical cyclone there is real concern of a potentially high death toll and of enormous destruction, particularly given the traditional housing that is so prevalent through the islands,” said the report.

“Cyclone Pam has destroyed all but one of mobile towers in Port Vila so no comms between Efate and both nth and sth provinces,” said a UNICEF employee. Read more…

Tuvalu, Kiribati, Solomon Islands

Meantime, Tuvalu’s prime minister has declared a state of emergency, after the deadly cyclone caused widespread flash floods, severely affecting about half of his nation’s population.

The cyclone has also flattened homes, flooded fields and destroyed crops in Kiribati and the Solomon Islands, affecting thousands of families, said reports.

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 seen.  Solomon Star News

State of Disaster Declared in Solomon Islands

Significant aftershocks continue to pound Santa Cruz Islands region as govt. declares a State of Disaster

Solomon Islands government has declared a State of Disaster for Santa Cruz Islands after a meter-high tsunami triggered by a magnitude 8.0 quake engulfed the region on Wednesday.

• At least nine people are dead and many are missing after the tsunami damaged or destroyed more than 20 villages.

• Officials say scope of the disaster is much worse than initially thought and they  still don’t know the fate of the more outlying villages in the reef islands.

• The tsunami has wept away entire villages, spreading debris everywhere.

• “The force behind the meter-high [tsunami] wave swept everything in its path, especially in low-lying areas,” said an official.

•  “Many people have no clothes at all, everything was washed away.”

• Authorities say about 7,000 people have been displaced as a result of the tsunami,  but the number could reach much higher.

Tsunami Evaluation:
A destructive pacific-wide tsunami is not expected. However, local tsunami may occur. “Earthquakes of this size sometimes generate local tsunamis that can be destructive along coasts located within a hundred kilometers of the earthquake epicenter. Authorities in the region of the epicenter should be aware of this possibility and take appropriate action.” PTWC said.

Powerful Aftershocks Still Striking Solomon Isles

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:

• Powerful Earthquakes Strike Solomon Islands and

• Solomon Isles Tsunami Destroyed Several Villages

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.

• The mainshock which struck  on Sunday, January 03, 2010 at 22:37 UTC generated a 3-m high,  destructive tsunami.

• The tsunami slammed on the shores of Rendova Island and neighboring Tetepare Island at about 9:30 am local time on Monday (UTC + 11:00 Hours)

• At least 3 villages have been devastated, or damaged.

• Up to 70 homes on Baniata village on Rendova Island were reported as destroyed or damaged.

• The final damage toll may be much higher, local authorities said.

• No death or injuries reported because tsunami occurred during the day and the residents managed to flee to higher grounds.
  

• 9 additional aftershocks, 8 of which measured greater than M5.0, have struck near the epicenter of the mainshock.

• The largest of the aftershocks measured up to 6.4Mw, and struck at a depth of about 35km some 35 km  SE of Gizo (8.346°S, 157.067°E), New Georgia Islands, Solomon Isles on Monday, January 04, 2010 at 11:28 UTC.

• The latest aftershocks sent frightened villagers in the Western province of Solomon Islands again running to higher grounds fearing another tsunami.

• Landslides were reported on Rendova and Tetepari islands.

• Seven fishermen are reported missing.

• No serious injuries reported.

• About a third of the island of Rendova’s population of 3,500 people have been affected after more than 200 “houses” were destroyed.

Historic Seismicity

Tsunami Warning

The Pacific Tsunami Warning Centre in Hawaii earlier said the earthquakes generated  a 6cm (NON-Destructve) tsunami.

“[The tsunami] may have been destructive along the coasts near the earthquake epicentre.” It said.

NOAA/NWS/West Coast and Alaska Tsunami Warning Center said a tsunami was NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast.  However, local tsunamis may occur from underwater landslides at coastal locations which have experienced strong ground shaking.

An 8.1Mw quake struck about 60km NW of this earthquake on April 1, 2007, triggering  a tsunami near Solomon Islands which crashed into the town of Gizo the capital of the Solomon Islands Western Province (population 6,500),  killing 52 people (official death toll) and destroying almost the entire town. More than 5,400 people were left homeless.

In Tajikistan meanwhile…

News agencies reported that a 5.5Mw earthquake which struck Tajikistan on Saturday had destroyed more than 1,000 houses. There were no reports of human casualties as of posting.
