Quake triggers tsunami warning; advisory for B.C.

Updated: Sat Feb. 27 2010 11:25:58 News Staff

Tsunami warnings are in effect for much of the Pacific Rim after an 8.8-magnitude earthquake struck central Chile early Saturday morning. The quake also triggered a tsunami advisory for all of coastal British Columbia.

The advisory, issued by the West Coast Alaska Tsunami Warning Center, said there is the possibility of strong localized currents. While massive waves are not expected, low-lying areas and beaches are at risk.

Meanwhile, the tsunami warning issued by the Pacific Tsunami Warning Center includes parts of Central and South America, New Zealand, Russia, Japan, the Philippines, Hawaii and a number of Pacific islands.

“Sea level readings confirm that a tsunami has been generated which could cause widespread damage,” reads a bulletin issued by the Pacific Tsunami Warning Center. “Authorities should take appropriate action in response to this threat.”

Chilean President Michelle Bachelet said Saturday that a huge wave has already hit the Robinson Crusoe Islands, which are about 660 kilometres off the Chilean coast. There is no word yet on casualties or damage, she said.

The Center issued specific warnings for the entire state of Hawaii, saying the first wave of a tsunami could hit at 11:19 a.m. local time. …

Ecuadorean President Rafael Correa told the Ecuavisa television channel that a tsunami has already passed the Galapagos Islands. It caused a swell, but no damage, he said.

Elsewhere in the Pacific Rim, disaster management officials said they’ve been warned to expect waves as high as 2.3 metres to strike the archipelago’s northern and eastern islands and the nearby Tonga islands.

Charles McCreery, director of the Pacific Tsunami Warning Center, said the lead time before the tsunami is expected to hit grants officials throughout the region time to prepare. …

Should Saturday’s earthquake trigger a tsunami, it would not be the first time for a tremor in Chile.

After a 9.5-magnitude quake struck the country in 1960, a tsunami killed 140 people in Japan, 61 in Hawaii and 32 in the Philippines. According to Japan’s Meteorological Agency, that tsunami measured between one and four metres in height.

Chilean earthquake, Pacific tsunami warnings

Massive earthquake rocks Chile; tsunami warnings in Pacific

A magnitude 8.8 earthquake struck Chile early Saturday morning, prompting tsunami warnings across the Pacific Ocean.

Early reports indicate at least 78 people in Chile were killed by the temblor, which lasted 90 seconds.

The quake’s epicenter was 200 miles southwest of Chile’s capital, Santiago. It was 70 miles from the nation’s second-largest city, Concepcion, home to 200,000 people.

Speaking to her people from an emergency response center, Chilean President Michele Batchelet said there was no cause for panic.

The correct spelling is Bachelet.

Best wishes to the survivors of this disaster, and to all people concerned in Chile, and in other countries.

Hornbill removes warthog’s parasites

Southern ground hornbill

From the BBC:

Africa: warthog befriends hornbill for grooming favour

By Jody Bourton
Earth News reporter

A warthog has been pictured being groomed by a huge bird known as a ground hornbill.

The warthog approached the southern ground hornbill seeking the favour, and the bird obliged by removing parasites from the warthog’s body.

Similar interactions occur between warthogs and other animals such as banded mongooses.

But hornbills are not known to groom in this way, say scientists who photographed the incident.

Details of the behaviour are reported in the African Journal of Ecology.

“The warthogs approached the hornbills and then lay down on their sides to be cleaned,” explains Dr Hendri Coetzee of North West University, Potchefstroom, South Africa.

“The warthogs were very nervous, because this behaviour most probably makes them more vulnerable to predation.”

Opposites attract

Dr Coetzee says he repeatedly observed similar interactions between common warthogs (Phacochoerus africanus) and southern ground hornbills (Bucorvus leadbeateri) in the Mabula Game Reserve in South Africa’s Limpopo Province.

The arrangement is mutually beneficial: the warthog gets a cleaning service and the ground hornbill a nutritious and easily obtainable food source.

Other animals will also groom warthogs, picking off parasites from the wild pig’s body.

For example, banded mongooses remove ticks from warthogs, in what is believed by scientists to be the only symbiotic relationship between two mammal species.

Oxpecker birds also regularly clean the skins of a number of African mammals, including zebra and hippos.

But the interactions with the hornbills stood out because the warthogs usually initiated the grooming.

Southern ground hornbills are large black plumaged birds, with powerful beaks that can kill tortoises and large snakes.

“What surprised me was how delicately they were removing parasites from the warthogs,” says Dr Coetzee.

“Adult warthogs even tolerated the ground hornbills probing their ears and around their more delicate areas under their tails.”

Dr Coetzee speculates that the animals might be behaving this way in part because they are living on a game reserve, where they might be less threatened and more relaxed.

“It is most likely the result of learned behaviour and regular contact between the same individuals living under somewhat artificial circumstances, where the risk of predation is reduced,” he explains.

August 2010: A group of 40 red-billed oxpeckers are being flown into the Mountain Zebra National Park near Cradock in South Africa this month. The introduction of this brown-coloured bird with its characteristic red bill and bright yellow-ringed eye will benefit both the wildlife in the park and local stock farmers: here.

Welsh coal tit 100 millionth British bird record

From Wildlife Extra:

Coal tit in South Wales is BTO’s 100 millionth record

25/02/2010 16:53:46

The British Trust for Ornithology’s (BTO) collection of bird records in its databank hit 100 million this week, making this the most important bird resource in the country. The record-breaking submission was submitted to the BirdTrack survey.

February 2010. The BTO has been collecting information on Britain’s birds since 1933 through a variety of citizen science surveys. Since 2002 an increasing number of these large-scale surveys have been run using on-line systems that allow volunteers to enter their observations and view the results. The BirdTrack survey was set up in 2004 to collect records from individual birdwatchers of all abilities to help monitor the movements and distribution of birds across the whole of Britain and Ireland. The 100 millionth observation submitted was a Coal Tit in South Wales.
