Four large earthquakes struck in different regions of the globe within a day. Has anyone ever seen this before? I don't recall anything like it.

Major quakes hit Japan and Indonesia
Story Highlights
Both quakes struck within minutes of each other; no reports of injuries
Both prompted tsunami warnings, but neither expected to be serious
Earthquakes between magnitude 6.0 and 6.9 are considered "strong" by USGS
(CNN) -- A magnitude 6.9 earthquake rattled Japan on Thursday, within minutes of a magnitude 6.6 earthquake in Indonesia, the U.S. Geological Survey said.
There were no immediate reports of damage or injuries from either quake, but both prompted tsunami warnings, although Japan's Meteorological Agency predicted it would be small, about 50 centimeter (20 inches).
The Indonesian quake occurred at exactly 9 a.m. (0000 GMT), the USGS said. Its epicenter was offshore, about 75 miles (120 km) north of Ternate in the province of Moluccas in eastern Indonesia. The quake was strongly felt in Ternate.
The Indonesian Meteorological and Geophysical Department issued a tsunami warning shortly afterward -- standard procedure for a quake of magnitude 6.6 or higher with an epicenter offshore.

Quake rattles northern Chile
The Japanese quake occurred at 9:21 a.m. (0021 GMT). The USGS initially classified its magnitude as a 7.2, but later reduced it.
The quake's epicenter was offshore, about 80 miles (125 km) south-southwest of Kushiro on the northern Japanese island of Hokkaido, and about 21.7 miles (35 km) below the Earth's surface.
The Indonesian quake was much deeper -- about 57.9 miles (93 km). In general, earthquakes centered closer to the Earth's surface produce stronger shaking and can cause more damage than those further underground.
Earthquakes between magnitude 6.0 and 6.9 are considered "strong" by the USGS.
The National Oceanic and Atmospheric Administration said neither quake posed a Pacific-wide tsunami threat. However, "earthquakes of this size sometimes generate local tsunamis that can be destructive along coasts located within a hundred kilometers of the earthquake epicenter," the administration said. |

Quake rocks Chile; no major damage seen
SANTIAGO, Chile (AP) � A magnitude-5.8 earthquake rocked northern Chile on Wednesday, causing landslides that blocked highways but no immediate reports of victims or major damage.
The quake hit at 12:12 a.m. Wednesday in Chile's northernmost province of Tarapaca, according to the U.S. Geological Survey's National Earthquake Information Center.
The Seismological Institute of the University of Chile said the quake was centered near the town of Pica, outside the coastal city of Iquique. It was felt hundreds of miles away.
The government's Emergency Bureau said the quake caused some landslides that blocked highways, but there were no immediate reports of victims or damage, though officials were seeking word from small Andean towns.
The U.S. earthquake center said the epicenter was located 4.8 miles below ground, while Chilean seismologists said it was much deeper. |

Quake in Iran kills 4, sends tremors across Gulf
By ALI AKBAR DAREINI � 11 hours ago
TEHRAN, Iran (AP) � A strong earthquake rocked southern Iran on Wednesday, killing four people and sending tremors across the Persian Gulf to the skyscrapers of Dubai.
The country's seismological center said the magnitude 6 quake struck at 3:30 p.m., with the epicenter about 850 miles south of the capital Tehran in the province of Hormozgan.
The region's main city, Bandar Abbas, is one of Iran's key ports and home to a large oil refinery that primarily serves the domestic market. People in the port city, reached by telephone, said panicked residents ran into parks when the tremors started.
"When the quake struck, it was like a snake bite," said Hani Shokouhi, a resident of Bandar Abbas. "Then, the chandeliers and drawers were moving from one side to the other in the house."
Shokouhi said many residents remained in the streets, too afraid to return to their homes.
The quake, which an official at the seismological center said was followed by 10 aftershocks, knocked out power and caused minor damage on the Gulf island of Qeshm. State television reported four people were killed and 26 injured.
The U.S. Geological Survey estimated the initial quake's strength at magnitude 6.1.
Abdolkarim Setareh, a local official in the epicenter town of Bandar-e-Khamir said extensive damage was unlikely.
"Houses in this region have been built in recent years and are resistant to earthquakes. Only minor damage has been reported from a dozen villages so far," he told The Associated Press by telephone. |

Obviously, something is shifting in the earth, but Iran is not part of the Ring of Fire plate, so it seems to be unusually fundamental. |

If that was a belly ache, wait for the test scheduled October 21, 2008--when they actually collide some particles. |

I'm sorry if you were disappointed.
It is important to keep the strength of earthquakes in perspective. The potentially devastating earthquakes are in the 8+ to 9+ range on the Richter Scale. How much damage they do depends on where they are located and how deep they are. When one strikes a population center, there is a lot of damage. When an 8+ strikes a population center in an underdeveloped nation, there are lots of deaths. If a 9+ strikes a population center even in a developed country, there will be a great many deaths.
A 6.x quake is rated as "strong," but does not necessarily cause a lot of damage or deaths. There are about 120 a year.
A 7.x quake is rated as "major." There are an average of 18 a year.
We had two 7.x quakes yesterday.
There is an average of one 8.x quake a year, and a 9.x quake occurs about once every 20 years.
http://en.wikipedia.org/wiki/Richter_magnitude_scale
As anyone who has paid attention to earthquakes in the news knows, there is nothing especially unusual about a 6.x quake. A 7.x quake is somewhat unusual. What is unusual is having so many at one time in so many widely separated places.
Early estimates of the magnitude of earthquakes are subject to change, and these appear to already have been revised.
The Indonesian quake is now being rated at 7.6, which is a major quake. Indonesia is one of the most geologically active -- and dangerous -- places on the planet.
The Japanese quake is now rated as a 7.0.
http://www.radioaustralia.net.au/news/stories/200809/s2361688.htm?tab=latest
Note that a 6.0 quake is equivalent to a 1 megaton nuclear explosion. It so happens that's what went through the minds of many people when the 6.1 quake was recorded around the world striking Iran.

Iran earthquake triggers N-bomb test scare globally
TEHRAN: At 6.1, the earthquake that rocked Iran's main oil port of Bandar Abbas, was rated "strong" but not seen as likely to cause major damage. But the shock took a toll of nerves in many world capitals as speculation that Iran had tested a nuclear bomb spread like wildfire.
The hysteria soon died down, but not before the west wondered if its worst nightmare - of a nuclear bomb in the hands of a theocratic Islamic state - had come true after all. Though Iran's nuclear capacity is unproven, US's high-pitched campaign as well as sabre-rattling by Iran's leaders has kept nations on the edge.
With Iran's leaders like President Mahmoud Ahmedinejad - who's view that the Holocaust never happened has hardly bolstered the world's confidence - equating a prospective nuclear bomb with national pride, anything could be possible. Of course, capacity has not always matched claims as the crude photo shop to cover up a failed missile launch showed, but Tehran enjoys an unpredictable reputation.
In the end, as seismic recorders delivered their findings, a collective sigh of relief might well have risen as it turned out a tectonic churn rather than a centrifuge was responsible for the Persian landmass shaking. It might still, as some US agencies might hold, have been a close call.
The quake itself took a small toll of lives according to reports which said southern Iran was rocked on Wednesday, killing four people and sending tremors across the Persian Gulf all the way to Dubai.
The country's seismological center said the magnitude 6 quake struck at 3.30pm, with the epicenter about 850 miles south of the capital Tehran in the province of Hormozgan.
In 2005, a quake in southern Iran killed 612 people. A quake flattened the same region in 2003, killing 26,000. |

The quake, which killed seven in Iran, was followed by a 4.9 aftershock.

A strong earthquake struck southern Iran yesterday, killing at least seven people and injuring dozens of others, while aftershocks spurred the evacuation of thousands of people from buildings across the Emirates.
Today Iranian state radio said a magnitude 4.9 aftershock jolted the same area in southern Iran.
The report said it struck Bandar Khamir at 6:46 am and was the strongest in a string of aftershocks, following Wednesday�s quake.
Yesterday's 6.1 magnitude quake struck at about 3pm, causing tremors in the UAE a short time later. The epicentre of the quake was reportedly near the port city of Bandar Abbas in south-west Iran. Most of the damage in Iran occurred on Gheshm island, where 100 houses were destroyed in rural areas, according to the state news agency IRNA. Reports suggested up to 45 people may have been injured.
As the shockwaves reached the UAE, witnesses said buildings swayed in Sharjah, Dubai and Abu Dhabi, where the tremors lasted a few seconds.
In Dubai, companies along Sheikh Zayed Road evacuated their offices and the Civil Defence Authority and police sent teams onto the streets, but there were no reports last night of any casualties or damage. The Dubai International Financial Centre was among the buildings evacuated.
�It happened all of a sudden, and we felt it because our chairs started rocking back and forth and side to side,� said Alyssa Brown, 29, an Australian working as a legal secretary at DLA Piper in Emaar Business Park near The Greens who was at her desk when the tremors shook the ground. �The blinds started moving too. It lasted for about 10 seconds. Everyone started freaking out.�
In Dubai Media City, employees evacuated Al Thuraya Tower after the alarm was sounded. �We all felt it and then heard the alarm sound. I�ve never felt anything like that before,� said James Noughton, a media executive who works in the building.
Charbel Karam, 25, a designer who works in Emirates Towers, said: �Immediately everyone ran down the stairs to get outside. The security shut down the elevators. Everything seemed to be crazy, including the traffic on the roads. People were just going left and right. It was chaos.�
Mohammed Mashroom, director of the survey department at Dubai Municipality, said the epicentre of the earthquake was at Bandar Abbas, one of Iran�s main ports which is home to a large oil refinery that primarily serves the domestic market. He said the magnitude felt in the UAE ranged from 2.8 to 4.8.
�Tremors were felt all through the city but all buildings in Dubai are safe,� he said.
Jamal Abdullah, head of the civil engineering department at American University of Sharjah, said the earthquake was of similar magnitude to the one that rocked the UAE in Nov 2005.
�This one was probably slightly stronger and lasted for a longer period of time,� Mr Abdullah said.... |

It appears there was a swarm of quakes in Indonesia, if I have this right, prior to the bigger one.

Four strong earthquakes strike on Wednesday
Bengkulu, (ANTARA News) - Four tectonic quakes measuring 5.0 to 5.8 on the Richter occurred in Indonesia on Wednesday.
According to the Meteorology and Geophysics Agency (BMG) three of the quakes struck Aceh while the other one shook West Java.
The first quake measuring 5.2 occurred at 07:18:50 with its epicenter 36 kilometers southwest of Sinabang, Aceh, in a depth of 30 kilometers.
The other quake measuring 5.8 struck at 10:00:26 with its epicenter 30 kilometers eastwest of Sinabang in a depth of 10 kilometers.
The third took place in Aceh at 11:02:17 measuring 5.0 with its epicenter 100 kilometers eastwest of Sinabang and in a depth of 19 kilometers.
The epicenter of the last one measuring 5.0 was located 90 kilometers southwest of Tasikmalaya, West Java, in a depth of 15 kilometers. |
Historically, such swarms have sometimes preceded volcanic eruptions, specifically, Krakatoa.

Sorry I only get CNN. Who says this is unusual seismologists or news reporters?
Anyway I like wiki too

At least earthquakes can't be blamed on man.
Maybe the EQs are triggering each other? |

The Bible (Matt: 24) days that in the last days there shall be earthquakes in diverse places . . .

You do know there are thousands of earthquakes everyday all over the world......just cos some new agencies went with a few that happened doesn't mean the worlds gonna fall apart.
Its also known that earthquakes can trigger other earthquakes around the world. So its totally possible its a domino effect.

Yep! Maybe that's the way God planned it. Then again maybe not. The scientists who say global warming is real may be right, then again it may be scam.
