The quake comes two days after an 8.0-magnitude earthquake struck the same region, triggering a tsunami that killed five people but didn't threaten the wider region.FULL STORY
A 6.5-magnitude earthquake struck this afternoon in the Pacific off the western coast of Guatemala, the U.S. Geological Survey reported.
Striking about 17 miles (27 kilometers) below sea level, the tremor was centered about 19 miles west-southwest of Champerico, Guatemala, and 115 miles from the capital, Guatemala City. The quake was not far from southern Mexico, with the USGS reporting it was 27 miles south-southeast of the border community of Suchiate, Mexico.
Editor's note: A 7.4-magnitude earthquake hit Wednesday off the coast of Guatemala, according to the U.S. Geological Survey. Guatemalan officials say at least 48 people died and about 125,000 people were without power.Â The quake, centered about 15 miles from the coastal city of Champerico at a depth of 26 miles, was felt throughout Central America and as far north as Mexico City. Below are updates:
[Updated at 9:27 p.m. ET] At least 48 people were killed as a result of the earthquake, Guatemalan President Otto Perez Molina said.
[Updated at 5:07Â p.m. ET] The death toll in the Guatemalan quake has risen to at least 29, said David de Leon, a spokesman for the country's disaster relief agency.
As if they haven't had enough headaches in New Jersey in the past week, this morning they can add earthquake to the list.
The magnitude-2.0 temblor struck at 1:19 a.m. and was centered two miles south-southeast of Ringwood, New Jersey, not far from the border with New York. The depth was 3.1 miles, according to the U.S. Geological Survey.
A 3.9-magnitude earthquake struck northeastern Arkansas Monday morning, according to the U.S. Geological Survey
The quake was centered about six miles from Parkin, near the Tennessee border, at a depth of 3.2 miles.
Editor's Note: A sizable 7.7-magnitude earthquake in western Canada triggered a tsunami that headed toward Hawaii, prompting evacuations of thousands from coastal areas. Geophysicists had feared waves between 3 and 7 feet to lash the Hawaii islands, beginning about 10:28 p.m. local time Saturday (4:28 a.m. Sunday ET). But Hawaii seems to have been spared the worst. There have been no apparent damage from the quake in Canada, nor from the tsunami in Hawaii. Here is the full story.
Here are the latest developments: Â
[Update 7:19 a.m.] Evacuations for coastal residents have been lifted, CNN affiliate Hawaii News Now reports.
[Update 7:06 a.m.] The tsunami warning for Hawaii has been canceled. Â A tsunami advisory is now in effect.
A tsunami advisory indicates that strong currents or waves that are dangerous to those in or very near the water are expected, but significant inundation is not expected.
[Update 6:35 a.m.] Exercise patience. That is the message from Honolulu Mayor Peter Carlisle. "We are not in a position now where we believe it's safe for you to return," he told reporters. "I understand it's an unpleasant thing to stay away from your homes, your loved ones, your pets."
He said that until the island is out of the entire cycle of waves, it will be difficult to predict what will happen. "Sometimes the last ones are the dangerous ones," he said referring to the waves.
One reason why authorities are hesitant to issue the all-clear are reports of 4-foot waves
Wailoa Harbor on the Big Island reporting 4 ft waves every six minutes.

[Update 6:26 a.m.]Â There have been 23 aftershocks measuring 4.1 or greater since a 7.7-magnitude quake struck off the coast of QueenÂ Charlotte Islands in Canada late Saturday, the U.S. Geological Survey said.
[Update 5:50 a.m.] So when can Hawaiians return home? "We believe weâ€™ll have enough information in the next 2 to 3 hours to be able to determine when and if weâ€™ll be able to issue an all clear," said Peter Carlisle, Honolulu mayor. "As of now we do not want people returning to their homes. We want them to stay in a location where they are safe."
Earthquake experts around the world say they are appalled by an Italian court's decision to convict six scientists on manslaughter charges for failing to predict the deadly quake that devastated the city of L'Aquila. They warned the ruling could severely harm future scientific research.
The court in L'Aquila sentenced the scientists and a government official Monday to six years in prison, ruling that they didn't accurately communicate the risk of the earthquake in 2009 that killed more than 300 people.
The trial centered on a meeting a week before the 6.3-magnitude quake struck. At the meeting, the experts determined that it was "unlikely" but not impossible that a major quake would take place, despite concern among the city's residents over recent seismic activity.
[Update 8:55 p.m. ET] The U.S. Geological Survey revised its report of Tuesday's earthquake to magnitude 4.0, down from a preliminary magnitude of 4.6. The epicenter was pinpointed 4 miles west-southwest of Hollis Center, Maine, at a shallow depth of 4.2 miles.
Despite the downgrade, the quake was felt as far away as Boston, Massachusetts; Albany, New York, and even Waterbury, Connecticut, according to the USGS.

"My entire house shook for 3 to 4 seconds. It felt like it was about to collapse," a viewer from Everett, Massachusetts, wrote to CNN affiliate WCVB in Boston.
[Original post] An earthquake of preliminary magnitude 4.6Â hit Maine at 7:12 p.m. ET Tuesday, according to the USGS website. The earthquake happened 3 miles (5 kilometers) west of Hollis Center, Maine.
A magnitude 6.2 earthquake struck off Japan's eastern coast early Tuesday, the U.S. Geological Survey reported.
With a depth of 9 kilometers (5.5 miles), the temblor was about 150 kilometers (93 miles) east-southeast of Hachinohe and 550 kilometers (342 miles) north-northeast of Tokyo, according to the U.S. agency.
The quake occurred just over a year and a half after a magnitude 9.0 earthquake triggered a huge tsunami off Japan, resulting in thousands of deaths and the world's worst nuclear crisis in a quarter century.
The Japan Meteorological Agency, however, did not issue any tsunami warnings or advisories immediately after the Tuesday morning quake, according to its website. No such warnings were issued by the Pacific Tsunami Warning Center either.
A powerful 6.2-magnitude earthquake struck near Mexico's Baja peninsula Tuesday, the U.S. Geological Survey said.
The quake's epicenter was 47 miles (75 kilometers) north of La Paz, Mexico, USGS said.
There were no immediate reports of damage or injuries.FULL STORY
[Updated at 1:17 p.m. ET] A tsunami warning for Costa Rica, Nicaragua and Panama in the wake of a 7.6-magnitude earthquake in the region has been canceled, the Pacific Tsunami Warning Center said Wednesday.
[Updated at 11:35 a.m. ET]A tsunami warning issued after a 7.6-magnitude earthquake off the coast of Coast Rica on Wednesday remains in effect for Costa Rica, Panama and Nicaragua, according to the Pacific Tsunami Warning Center in Ewa Beach, Hawaii. The warning was canceled for other locations.
[Updated at 11:28 a.m. ET] The Pacific Tsunami Warning Center in Ewa Beach, Hawaii, has issued an expanding regional tsunami warning and watch for parts of the Pacific located closer to the 7.6-magnitude quake off Costa Rica. The center said Hawaii could be elevated to watch or warning status as new data comes in.
[Updated at 11:18 a.m. ET] A tsunami watch issued for the Caribbean after a 7.6-magnitude quake struck the coast of Costa Rica has been canceled. The watch was inadvertently sent by the Pacific Tsunami Warning Center, and meant for the Pacific.
[Updated at 11:14 a.m. ET] The U.S. Geological Survey has reduced the magnitude of an earthquake that struck off the coast of Costa Rica from 7.9 to 7.6.
[Posted at 10:55 a.m. ET] An earthquake with a preliminary magnitude of 7.9 struck off the coast of Costa Rica, the U.S. Geological Survey said.
The quake was recorded on the Costa Rican coast, about 95 miles west of the capital, San Jose, and ran more than 28 miles deep.
A tsunami watch was in effect for much of the Caribbean, including along the coastlines of Brazil, Mexico, most countries in Central America and many islands.
"Earthquakes of this size have the potential to generate a widespread destructive tsunami that can affect coastlines across the Caribbean region," the U.S. government said.FULL STORY
[Updated 10:06 a.m. ET] People in eastern areas of the Philippine island of Mindanao should evacuate to higher ground after a 7.6-magnitude earthquake triggered a tsunami warning, an official of the Philippine Institute of Volcanology and Seismology said, according to the Philippine News Agency.
"Residents living (in) these areas facing the Pacific Ocean are advised to evacuate to higher places," he said, citing the areas of Surigao del Sur and Davao Oriental as particularly vulnerable.
[Updated 9:52 a.m. ET] A tsunami warning has been lifted for Japan, Taiwan and several Pacific islands, but a warning remains for Indonesia and the Philippines, the National Oceanic and Atmospheric Administration's tsunami center said Friday.
[Updated 9:50 a.m. ET] The U.S. Geological Survey has revised the magnitude of an earthquake that struck off the coast of the Philippines to 7.6, down from an initial reporting of 7.9, the agency said Friday.
[Posted 9:01 a.m. ET] An earthquake with a magnitude of 7.9 has struck off the coast of the Philippines, the U.S. Geological Survey said Friday.
The quake prompted a tsunami warning for parts of Indonesia, the Philippines, Taiwan, Japan, Guam and other areas, the Pacific Tsunami Warning Center said.
"An earthquake of this size has the potential to generate a destructive tsunami that can strike coastlines near the epicenter within minutes and more distant coastlines within hours," the tsunami warning center said.
The quake, which was about 20 miles deep, struck just before 8:50 p.m., the agency said. Its center was about 65 miles southeast of the town of Guiuan, in the Philippine province of East Samar.
Ed Serrano, the head of security at the Marco Polo Hotel in the city of Davao, about 250 miles south of Guiuan, said he felt the ground shake.
"The quake was very strong and the hotel guests were panicking. Most of them went outside," he said. "But now the situation is under control and we are waiting for official reports on how strong the quake was."
There were no immediate reports of damage or injuries.FULL STORY
A Japanese government report Monday heaped fresh criticism on the operator of the nuclear power plant where a disastrous accident was set off last year by the devastating earthquake and tsunami that hit the country.
The measures taken by Tokyo Electric Power Co. (TEPCO), the plant operator, and the Japanese nuclear regulator to prepare for disasters were "insufficient," the report by a government-formed panel of investigators said, and the response to the crisis was "inadequate."
The crippled Fukushima Daiichi plant spewed radiation and displaced tens of thousands of residents from the surrounding area in the worst nuclear accident since the 1986 Chernobyl disaster in Ukraine.
Even now, more than one year after the disaster began, TEPCO doesn't seem to be making much effort to clearly investigate the causes of the accident at the plant, the 10-member panel, led by Tokyo University engineering professor Yotaro Hatamura, said in the report Monday.FULL STORY
Japan was once again getting electricity from nuclear power on Thursday after two months as a nuclear-free nation.
Unit No. 3 at Kansai Electric Power Co. Ohi nuclear plant began generating power at 7 a.m., according to a report from broadcaster NHK.
The process of restarting the reactor had begun Sunday night.
The reactor will provide electricity to western Japan - which includes Osaka, Japan's second-biggest city.
Ohi's No. 4 reactor is scheduled to resume operations by July 24.
All 50 commercial nuclear reactors in Japan have been offline since May 5 for safety checks in the wake of the meltdown at the Fukushima Daiichi plant after last year's devastating earthquake and tsunami. The government has been conducting simulation tests for restarting its nuclear reactors in response to public concerns.
Before the March 2011 nuclear disaster, Japan had relied on nuclear energy for about 30% of its electricity needs, according to government figures.
An earthquake with a magnitude of 5.8 hit north central Italy on Tuesday, civil protection authorities said, nine days after a major quake in the region left seven people dead.
Civil protection officials told CNN there were fatalities in Tuesday's quake, but they said they did not yet have a confirmed number of dead.FULL STORY
A 4.3-magnitude earthquake rattled eastern Texas early Thursday, the U.S. Geological Survey reported.
The quake, at a depth of three miles, was centered near Timpson, about 155 miles east-southeast of Dallas, according to the USGS.Â It struck at 3:12 a.m. (4:13 a.m. ET).
At least one building in Timpson showed damage, with a number of bricks falling to the street below, CNN affiliate KLTV in Tyler, Texas, reported.
Ollie Barrett told KLTV that bricks from her chimney came crashing through her roof.
"There was a loud rumbling noise and then there was a lot of crashing," she said. Her 52-inch, wall-mounted TV was crushed.
A massive earthquake struck off the coast of the Indonesian island of Sumatra on Wednesday, triggering a tsunami watch for the Indian Ocean.
The magnitude 8.6 quake struck about 500 kilometers from Indonesia's Aceh province, the U.S. Geological Survey said. It took place at a depth of 33 kilometers.
The Pacific Tsunami Warning Center initially issued a tsunami watch for the entire Indian Ocean, but the watch has been cancelled.
Banda Aceh was devastated by a tsunami resulting from an earthquake in December 2004.
[Updated at 9:04 a.m. ET]Â The Pacific Tsunami Warning CenterÂ has cancelled its tsunami watch in the Indian Ocean.
"Sea level readings now indicate that the threat had diminished or is over for most areas," the center said.
[Updated at 8:34 a.m. ET]Â CNN's Kathy Quiano reports that officials have said about 14 aftershocks have rocked Indonesia after the initial 8.6 magnitude earthquake.
Officials are still telling residents to saying stay away from the coastline.
"We are hearing that many residents are choosing to stay away from their homes and have sought shelter on safer and higher ground," Quiano reported, noting that many of the people had taken part in regular drills given that they are prone to quakes and the devastation caused by the 2004 quake.
[Updated at 8:15 a.m. ET]Â Barry Hirshorn, a geophysicist from the Pacific Tsunami Warning Center, told CNN that while the earthquake was a 8.6 magnitude and is considered large, it could be much different than the 9.0 magnitude quake that hit in 2004. Because theÂ epicenterÂ of this recent quake is also nearly double the distance offshore, it also means that it could be less likely to create a massive tsunami.
Hirshorn added that was also largely in part to how the rupture of the earth took place in this tsunami. Hirshorn explained that the earthquake in 2004 made more of a vertical motion, which would produce larger waves, while this strike-slip earthquake creates more side-to-side motion.
"Tusnami-wise, we are lucky that way, for now," he said.
[Updated at 8:12 a.m. ET]Â Â A spokesperson for the Indonesian president said the situation in the country is under control but he still anticipates that tsunamis may hit the area.
Teuku Faizasyah said right now it is most important to ensure people that they are safe. Search and rescue teams have been deployed.
"What's important is to bring confidence among the people that the government is with them, that we are ensuring their safety," he told CNN.
Tsunami warnings are in place for another hour, he added, saying they will watch the remote areas of the country especially closely.
"We are really waiting to hear from the isolated areas, but hopefully we wont receive any bad news,"Â Faizasyah Â said.
[Updated at 8:01 Â a.m. ET]Â Â Waves were reported at 1-meter (3.3-feet) amplitude offshore in Meulaboh, Indonesia, but in other cities they were reported at about a foot or less, according to the Pacific Tsunami Warning Center.
A series of buoys also measured changes in wave height levels, indicating a tsunami couldÂ occur. Waves are normally small when they are out in the ocean, but are expected to be much higher when they reach the shore.
British Prime Minister David Cameron announced that Britain "stands ready to help if required."
[Updated at 7:44 a.m. ET] An evacuation order has been given by Thailand's National Disaster Warning Center for those along the Andaman coast after the earthquake, according to CNN affiliate MCOT.
The warning center's directorÂ Somsak Khaosuwann "urged people along the sea in the Andaman coastal provinces of Phuket, Krabi, Phang-nga, Ranong, Trang and Satun to evacuate to higher ground," according to MCOT.
MCOT, also known as Thai TV 9, noted that tremors were felt as far as Bangkok.
In the Maldives, some resorts were evacuated in advance of possible waves, according to CNN's Erin Burnett, who was on vacation in the region.
