A tsunami warning for Hawaii, triggered by a powerful earthquake in Canada, proved nothing more than a pre-Halloween scare for thousands of people this weekend. "The tourists are doing their best Chicken Little impressions," one CNN iReporter in West Maui, Hawaii, wrote early Sunday.

Sirens announced the tsunami warning across Hawaii on Saturday night, as thousands of revelers packed streets in Honolulu for the annual Hallowbaloo festival and many others in costumes headed to Halloween parties.

Restaurants, clubs and the festival immediately shut down and the parties turned into bumper-to-bumper traffic jams as residents headed to higher ground.

Visions of the devastating quake and tsunami that killed thousands in Japan in March 2011 fueled the fright, but the waves proved to be smaller and less powerful than feared.

While the warning said waves could surge between 3 and 6 feet, the largest wave, measured in Kahului on the island of Maui, was about 2.5 feet above ambient sea level, according to Gerard Fryer, senior geophysicist at the Pacific Tsunami Warning Center.

Transit officials in New York are preparing for a total shutdown of subway, bus and train service as Hurricane Sandy continues to bear down on the metropolitan region.


All service will be suspended at 7 p.m. on Sunday.

New York Gov. Andrew Cuomo ordered the Metropolitan Transportation Authority to start planning for an orderly suspension of service.

New York City subways and buses will start phasing out service at 7 p.m. Metro-North Railroad and the Long Island Rail Road will suspend service at 7 p.m. Sunday.

The city's mass transit system is the nation's largest. The subway alone has a daily ridership of more than 5 million.

The unexplained and mysterious sounds have been captured by hydrophones, or underwater microphones.

With Halloween approaching, it's natural to wonder just a little bit more than usual about things that go "bump" in the night. But what about things that go "bloop" in the deep sea?

Poltergeists, witches and ghosts aren't the only source for spooky seasonal mystery. In fact, scientists monitoring the oceans have uncovered a handful of sounds that can't be explained - at least not with any certainty.

With names like "The Bloop," "Train" and "Julia," the sounds have been captured by hydrophones, or underwater microphones, monitored by the National Oceanic and Atmospheric Administration (NOAA). Here are the six most mysterious noises ever heard in the sea, and what might have made them. [Listen to the Six Spooky Sounds]

1. The Bloop

The decidedly nonspooky nickname for this sound does little to dispel the mystery surrounding it. In 1997, NOAA hydrophones picked up one of the loudest sounds ever recorded off the southern coast of South America: the Bloop (which sounds like, well, a bloop), was recorded by two hydrophones nearly 3,000 miles (4,800 kilometers) apart.

It's still unclear whether Sandy will be a devastating storm or just a bad one.

It is clear, however, that Sandy will be remembered as the storm that broke all the rules and baffled the nation's top weather forecasters.

Early Saturday morning, the National Weather Service downgraded the storm from a hurricane to a tropical storm - only to return it to hurricane status a few hours later. Either way, forecasters warn, "widespread impacts" are expected along the coast.

Three days before reaching land - a time when the National Hurricane Center usually puts a bull's-eye on a small stretch of coast - government forecasters were still talking about the possibility of the storm striking anywhere from Maryland to New York.

Their uncertainty was especially surprising because hurricane track forecasts have become so good in the past couple of decades. They are usually accurate five or more days out.

Yet during a press conference on Friday, James Franklin of the NHC was still deflecting reporters' questions about Sandy's track. "We cannot be precise at this stage about exactly where it will come in," he said.

Forecasters say Sandy just isn't like other hurricanes.

"The whole thing is unprecedented," Henry Margusity of AccuWeather told NPR's Melissa Block. "We've never seen anything like this."

Santa Barbara authorities just released a statement explaining residents are in no immediate danger of a potential tsunami triggered by the 7.7 magnitude earthquake that struck northwest Canada at 9:04 pm Saturday tonight.

The quake was centered near a remote area of Prince Rupert, BC, according to the U.S. Geological Survey. The Pacific Tsunami Warning Centre has issued warnings for coastal areas from the northern tip of Vancouver Island to Cape Decision. Multiple aftershocks have been felt since the first tremor, according to the Toronto Star.

A tsunami warning was issued late Saturday for the coastal areas of northwest British Columbia following a 7.7 magnitude earthquake off the waters near Prince Rupert. It was followed by at least aftershocks.

People in coastal areas were told to move inland to higher ground while residents in low-lying coastal areas were ordered to be on alert for instructions from their local emergency officials after the tsunami warning was issued just before 8 p.m. local time.

The epicentre was reported in coastal waters about 40 kilometres south of Sandspit, B.C. at a depth of 19 kilometres.

Natural Resources Canada issued a statement Saturday: "A major earthquake occurred in the Haida Gwaii region. It was felt across much of north-central B.C., including Haida Gwaii, Prince Rupert, Quesnel and Houston. There have been no reports of damage at this time."

Mitt Romney cancelled one of three campaign stops this Sunday in reaction to the recent weather threat presented by hurricane "Sandy" which is predicted to affect parts of the eastern seaboard, thus stopping Romney from appearing at the Virginia Beach rally he had previously scheduled.

Meanwhile, President Obama has already been briefed on the storm as of late Wednesday and east coast residents are urged to monitor local weather reports for what is being called a "super storm".

With Sandy's wide wind field of 550 plus miles merging with a polar air mass over the eastern US, things could get pretty rough.

The storm also has the potential to bring massive amounts of rain and snow.

An excerpt from the New York Times reads, "The storm is also expected to dump as much as 10 inches of rain in the area where it makes landfall and to create a significant storm surge that will lead to flooding throughout a large coastal area, perhaps most seriously in Delaware, forecasters said.

A loud, unexplained noise set off dozens of calls to the Niagara County Sheriff's Office Friday morning after residents reported hearing an explosion so loud it shook their homes. YNN's Meg Rossman reveals the source behind that explosion and why there's no mystery behind that mystery boom.

It was the mystery boom heard 'round the world - or at least Niagara County that caused the Niagara County Sheriff's Office to field dozens of calls similar to this exchange from concerned residents:
