Reuters report

JOHANNESBURG, March 11 (Reuters) - Rescue workers on Friday found the body of a miner missing deep in a South African goldmine after an earthquake, making the final death toll two, mining firm DRDGOLD said.

The discovery ended a search that lasted almost 50 hours in the Stilfontein mine, where one other miner was killed after Wednesday's magnitude 5.3 earthquake caused rockfalls that blocked access tunnels.

Dozens of miners were injured in the quake and at one stage 40 were trapped some 2.4 kilometres (1.5 miles) underground.

Mine spokesman James Duncan said the body of the final missing miner was located on Friday afternoon. "They are recovering the body back to the shaft," he said.

Rescue teams were now being removed from the mine and detailed inspections of the damaged area would begin, Duncan said. Seven of the eight mine shafts were already back in production, he said.

South Africa: earthquake is linked with mining activity

A strong earthquake injuring a dozen of people and evacuating thousands in northern South Africa on Wednesday was probably caused by mining activity, experts said. The tremor, measured a preliminary five on the Richter Scale was "a secondary effect from mining activity," Ian Saunders, project leader of the South Africa's National Seismograph Network,was quoted as saying by the South African Press Association (SAPA). South Africa, the world's number one gold producer, has dug some 3,000 meters underground or ever deeper in the gold-rich Witwatersrand Basin, where the quake-affected region is located.

An earth tremor occurring in the neighboring Free State Province on Monday morning killed four gold miners after they were trapped by falling rocks inside a shaft belonging to Harmony Gold,the world's sixth largest gold mining company, reports Xinhuanet. Saunders said the epicenter of the earthquake on Wednesday was believed to be around Klerksdorp, North West, where major South African gold miners including Anglo American Goldfields and DRDGold operate mining shafts.

Around 3,200 miners at DRDGold's operations were being evacuated late on Wednesday afternoon after the earthquake, and 13miners who were injured were being treated at the scene, SAPA reported. According to VOA News, a gold mining company in South Africa says 42 of its miners are trapped following an earthquake measuring around 5.0 on the Richter scale.

DRDGold says the company has sent a rescue team to the mine located near the northern city of Klerksdorp, at the epicenter of the quake. It says at least 13 other miners suffered injuries in Wednesday's quake. The company says it is evacuating all of the 3,200 miners who were on duty. Police say another 38 people in the town of Klerksdorp suffered minor injuries. Several buildings in the area were damaged. NR

Central Iran, 22 February 2005, Magnitude 6.4

This earthquake killed at least 400 people in the Kerman Province of Central Iran, and injured many others. It occurred at 05.55 am, local time. It was about 250 km north west of the large earthquake of 26 December, 2003 (magnitude 6.6), which killed approximately 30,000 people

GREAT EARTHQUAKE - INDONESIA - 26 Dec 2004

This earthquake was the largest in the world since a Magnitude 9.2 event in Alaksa in 1964. It was the 4th largest event in the world since 1900.  It is estimated to have caused rupturing along the plate boundary, in a roughly north-north-west direction, of at least 500 km. The average displacement has been estimated at 15 metres. The zone of aftershocks is at least 1300 km long. As we all know, it caused a tsunami of devastating dimension, having caused deaths as far away as the east coast of Africa.

Minor tsunami effects were recorded on the west coast of Australia, and they are documented elsewhere on this web site.

23 Dec 2004, EARTHQUAKE SOUTH OF TASMANIA

This earthquake occurred approximately 1000 km southeast of Tasmania, at 14:59 hours GMT on 23 December. At Magnitude 8.1, it was the largest world earthquake of 2004. until a magnitude 9.0 earthquake off Indonesia occurred on 26 December.

The earthquake on 23 December was felt widely in Tasmania and New Zealand

NEW ZEALAND, 22 NOVEMBER 2004

NEWS RELEASE, 23 NOVEMBER 2004, Geological & Nuclear Sciences

LARGE OFFSHORE QUAKE FELT WIDELY IN SOUTH ISLAND A large earthquake that occurred under the sea southwest of Invercargill this morning was felt throughout much of the lower half of the South Island.

The magnitude 7.2 earthquake struck at 9.26am about 100km off the southern Fiordland coast at a depth of 33km, Geological and Nuclear Sciences Ltd (GNS) said.

Many people in the lower half of the South Island reported feeling the quake as a long rolling motion ? typical of large, distant quakes. Residents of a number of towns in Southland reporting goods falling off shelves.

People in high-rise buildings as far north as Palmerston North and New Plymouth reported feeling a gentle swaying motion.

The quake occurred in an area called the Puysegur Trench, which marks the boundary between the Australian and Pacific tectonic plates. " This was a large earthquake in global terms. Had it occurred under or near a population centre, there would be major damage," GNS seismologist Warwick Smith said. " The location of the earthquake, well offshore, meant that by the time the seismic energy reached land, it was relatively weak," Dr Smith said. Puysegur Trench is known as a seismically active area, so the quake's location was no great surprise to seismologists.

A quake of identical size (magnitude 7.2) occurred in similar location in October 1979. Aftershocks would occur during the next few weeks, but because of their distance from land, it was unlikely they would be felt strongly, Dr Smith said. Ground shaking from the earthquake was recorded throughout New Zealand on seismic instruments operated by the GeoNet project.

Worldwide, the earthquake was the eighth this year of magnitude 7 or more. Most of these were in the western Pacific or Indonesia. An earthquake of this magnitude would be capable of generating a damaging tsunami. " The absence of a tsunami at Bluff indicates that there was no substantial vertical movement of the ocean floor at the epicentre."

Immediately after the earthquake thousands of people visited the GeoNet website (www.geonet.org.nz), and many reported how they felt the quake. Dr Smith said these first-hand reports were extremely useful and would enable earthquake scientists to determine preliminary estimates of damage if a quake of the same size occurred on land.
