Deadliest earthquakes and tsunamis of the past century
Hong Kong (AFP) Feb 6, 2013 - Three villages were reportedly flattened in the Solomon Islands Wednesday when a tsunami triggered by an 8.0-magnitude quake crashed ashore.

Below is a list of the world's deadliest earthquakes, including quake-induced tsunamis, over the past century:

- 2011: Japan: more than 19,000 were killed when a tsunami triggered by an undersea quake slammed into the northeast coast, triggering a nuclear crisis at the Fukushima Daiichi atomic plant. Magnitude 9.0.

- 2010: Haiti: between 250,000 and 300,000 killed when a quake hits what is already one of the world's poorest countries, devastating the capital Port-au-Prince. Magnitude 7.0.

- 2008: Sichuan province, China: 87,000 dead or missing. A large number of children are among the dead, with shoddily-built schools blamed. Magnitude 8.0.

- 2005: Indian and Pakistani Kashmir: at least 75,000 killed with poor construction in the mountainous region accounting for the high death toll. Magnitude 7.6.

- 2004: Indian Ocean: more than 226,000 died when a tsunami sparked by an undersea earthquake off Indonesia hit countries around the Indian Ocean. Magnitude 9.1.

- 2003: Iran: More than 30,000 killed in and around the city of Bam, with mud-built homes blamed for the level of destruction. Magnitude 6.6.

- 2001: India: More than 20,000 killed when a quake hits Gujarat on India's Republic Day holiday. Magnitude 7.7.

- 1990: Iran: 50,000 dead when quake hits in the northwest of the country near the Caspian Sea. Magnitude 7.4.

- 1976: Tangshan, Hebei Province, China: officials said 242,000 people died, although some Western sources said the toll was higher. Magnitude 7.8.

- 1970: Mount Huascaran, Peru: earthquake and resulting avalanche killed 66,800. Magnitude 7.5.

- 1948: USSR: More than 100,000 people killed in and around Ashgabat in modern-day Turkmenistan. Magnitude 7.3.

- 1939: Erzincan, Turkey: 35-40,000 killed. Magnitude 8.0.

- 1935: Quetta, India (now Pakistan): more than 50,000 killed. Magnitude 7.6.

- 1932: Gansu province, China: around 70,000 died. Magnitude 8.0.

- 1927: Nanshan province, China: up to 200,000 dead. Magnitude 8.0.

- 1923: Yokohama, Japan: more than 142,000 people died in the Great Kanto earthquake and resulting fire, which destroyed Tokyo. Magnitude 8.2.

- 1920: Gansu, northwestern China: more than 100,000 killed. Magnitude 8.5.

A huge earthquake that struck off the Solomons Islands Wednesday was another reminder of the power of the volatile "Ring of Fire", a vast zone of volcanic instability that encircles the Pacific Ocean.

The 8.0-magnitude earthquake was feared to have flattened villages in the Solomons, and generated small tsunami waves that reached Pacific nations' coasts, triggering emergency sirens and evacuations.

Australia's earthquake monitoring agency and the Pacific Tsunami Warning Centre said a wave measuring three feet (90 centimetres) had been recorded at Lata, on one of the Santa Cruz islands in the Solomons.

The Ring of Fire reaches from Indonesia to the coast of Chile in a 40,000 kilometre (25,000 mile) arc of seismic violence that unleashes earthquakes and volcanoes around the Pacific rim almost every day.

Most of history's deadliest quakes, tremors and volcanic explosions have occurred along this weak line in the Earth's crust, including the eruptions of Krakatoa near Java and Mount St Helens in the United States, as well as the massive quake that sparked the Indian Ocean tsunami of December 2004.

The Ring of Fire stretches along the western coast of the Americas and through the island nations of the South Pacific and on through Southeast Asia.

It is an interconnected circle of fault lines -- cracks in the Earth's hardened upper crust -- which are under constant pressure from super-hot molten rock beneath.

Occasionally the fissures give in and explode, creating volcanic eruptions and causing the land on either side of the fault line to shift and buckle violently, triggering earthquakes.

The fault lines are actually the margins of huge plates of rock on which the continents sit. These plates are in constant motion.

The 9.3-magnitude quake that struck Indonesia on December 26, 2004 unleashed tsunamis that crashed into Indian Ocean shorelines, killing more than 220,000 people.

The world's largest-ever registered tremor, the 9.5-magnitude Valdiva quake, shook Chile in 1960 and churned up a tsunami that killed scores in Japan and Hawaii.

A 9.0-magnitude undersea earthquake off Japan in 2011 triggered a tsunami that left about 19,000 people dead or missing, and caused a meltdown at the Fukushima nuclear power plant in the world's worst atomic disaster in 25 years.

In 2007 a tsunami following an 8.0-magnitude earthquake killed at least 52 people in the Solomons and left thousands homeless.

Key facts about the quake-hit Solomon Islands
Honiara (AFP) Feb 6, 2013 - A powerful 8.0-magnitude earthquake rattled the Solomon Islands on Wednesday, triggering a regional tsunami warning. Here are some key facts about the South Pacific nation:

-- GEOGRAPHY: The Solomons comprise hundreds of islands with a total land area of 27,540 square kilometres (10,630 square miles).

It is a tropical nation and its main islands are mostly rugged and jungle-clad, although the country includes coral atolls.

It has a number of active volcanoes and severe earthquakes routinely hit the area, although seldom cause damage

Its larger islands include Choiseul, Guadalcanal, Santa Isabel, New Georgia and Makira.

-- POPULATION: In July 2012 the population was estimated to be 584,578, with Melanesians making up 94.5 percent. Indigenous Polynesians and migrant Micronesians also populate the islands.

-- RESOURCES: These include fish, forests, gold, bauxite, phosphates, lead, zinc and nickel.

-- HISTORY: Parts of the Solomons have been occupied for 20,000 years.

Spaniard Alvaro de Mendana arrived in 1568 to give it the name, believing the islands held the secret of Biblical King Solomon's gold.

In the late 19th century the British government established a protectorate over part of the Solomon Islands, which was later extended

The island of Guadalcanal was the site of the first major offensive by Allied forces against the Japanese empire in World War II

The Solomons became independent on July 7, 1978.

The Head of State is Queen Elizabeth II, represented by Governor General Frank Kabui.

Prime Minister Gordon Darcy Lilo has held office since November 2011.

Scientists underestimated potential for Tohoku quake. Now what?
Corvallis, OR (SPX) Jan 29, 2013
The massive Tohoku, Japan, earthquake in 2011 and Sumatra-Andaman superquake in 2004 stunned scientists because neither region was thought to be capable of producing a megathrust earthquake with a magnitude exceeding ? 8.4. Now earthquake scientists are going back to the proverbial drawing board and admitting that existing predictive models looking at maximum earthquake size are no longer ... read more
