A magnitude 5.2 earthquake has hit the Western Australian mining town of Kalgoorlie-Boulder this morning.
It is the strongest earthquake in 50 years to hit the region. The Goldfields region of Western Australia is considered one of the more geologically stable regions of Australia, in comparison to the southwest corner of the state, which is an active zone at the edge of the Yilgarn block.
Kalgoorlie is located 600 kilometres (370 miles) east of the capital — Perth — and is historically the largest gold producing centre of its type in Australia. Kalgoorlie is also the largest urban centre in the goldfields region, and has the largest number of buildings that would be vulnerable to such an earthquake.
Minor casualties have been reported, and miners and schoolchildren have been evacuated. Buildings have been damaged in Kalgoorlie.
President Barack Obama open the 47-nation Nuclear Security Summit in Washington. The president says he wants new commitments to secure weapons-grade plutonium and uranium to prevent nuclear terrorism.
With concerns about the nuclear ambitions of Iran and North Korea a major backdrop to the conference, this is the biggest U.S.-sponsored gathering of world leaders in more than 60 years.
The New START treaty was signed on April 8, 2010 in Prague by U.S. President Obama and Russian President Medvedev and Iran will hold the Tehran International Conference on Disarmament and Non- Proliferation, 2010, announced on April 4, 2010 and to be held April 17–18, 2010.
The Summit is the largest gathering of heads of state called by a United States president since the 1945 United Nations Conference on International Organization. Delegations from forty-six governments plus the United States are attending, thirty-eight of which are represented by heads of state or government. Read More…
The Castle Bravo, a 15-megaton hydrogen bomb, is detonated on Bikini Atoll in the Pacific Ocean, resulting in the worst radioactive contamination ever caused by the United States.
Castle Bravo was the code name given to the first U.S. test of a so-called dry fuel thermonuclear hydrogen bomb device, detonated on March 1, 1954, at Bikini Atoll, Marshall Islands, by the United States, as the first test of Operation Castle.
Fallout from the detonation—intended to be a secret test—poisoned the islanders who inhabited the test site, as well as the crew of Daigo Fukuryū Maru (“Lucky Dragon No. 5″), a Japanese fishing boat, and created international concern about atmospheric thermonuclear testing. Read More…
Australian Prime Minister Kevin Rudd makes a historic apology to the Indigenous Australians and the Stolen Generations.
The Stolen Generations is a term used to describe those children of Australian Aboriginal and Torres Strait Islander descent who were removed from their families by the Australian and State government agencies and church missions, under acts of their respective parliaments.
The removals occurred in the period between approximately 1869 and 1969, although, in some places, children were still being taken in the 1970s. Read More…
The British First Fleet, led by Captain Arthur Phillip, landed at Sydney Cove, establishing the first permanent European settlement in Australia.
The First Fleet is the name given to the 11 ships which sailed from Great Britain on 13 May 1787 to establish the first European colony in New South Wales.
It was a convict settlement, marking the beginnings of transportation to Australia.
On 26 January 1788, the fleet weighed anchor and by evening had entered Port Jackson. The site selected for the anchorage had deep water close to the shore, was sheltered and had a small stream flowing into it.
Phillip named it Sydney Cove, after Lord Sydney the British Home Secretary. This date is still celebrated as Australia Day, marking the beginnings of the first British settlement. Read More…

An 8.3 magnitude earthquake in the Samoa Islands region causes a tsunami and kills at least 50 people.
The temblor generated three separate tsunami waves that are spreading, the largest of which measures 5.1 feet from sea level height and recorded an 3-inch rise in sea levels near the epicenter according to the Pacific Tsunami Warning Center in Ewa Beach, Hawaii.
The quake occurred near the Kermadec-Tonga Subduction Zone in the Pacific Ring of Fire, where continental plates in the earth’s crust meet and earthquakes and volcanic activity are common.
Samoa evacuated the entire city of Apia, the country’s capital city, moving thousands of residents to higher ground. Journalist Cherelle Jackson reported that the city quickly emptied in the aftermath of the earthquake and tsunami, “All the schools, workplaces everyone has walked up – it’s like a ghost town.” Read More…
A dust storm, described as “the worst in at least 70 years”, sweeps across several Australian states, covering Brisbane, Canberra and Sydney in red dust, Canberra, experienced the dust storm on 22 September, and on 23 September the storm reached Sydney and Brisbane.
On 23 September, the dust plume measured more than 500 kilometres (310 mi) in width and 1,000 kilometres (620 mi) in length and covered dozens of towns and cities in two states.
By 24 September, analysis using MODIS at NASA measured the distance from the northern edge (at Cape York) and southern edge of the plume to be 3,450 km.
Air particle concentration levels reached 15,400 micrograms per cubic metre of air (by comparison, normal days register up to 20 micrograms and bushfires generate 500 micrograms). Read More…
