The quake struck at 3:35 p.m. Hawaii time at a depth of about 16 miles and about 632 miles southwest of Anchorage.

Strong winds push waves all the way up the beach on Friday, Dec. 21, 2018, in Port Royal.
"It's not like what you see with a tsunami wave caused by an earthquake," said Chris Fisher, a meteorologist with the National Weather Service.
But it's a fairly rare occurrence. Last week's apparent meteotsunami caused water levels to jump by nearly a foot and forced beachgoers from Naples to Sanibel Island to scurry out of the way of waves last week.
A meteotsunami - not to be confused with a tsunami - consists of large waves caused by air pressure disturbances and quick-moving storms, according to the National Oceanic and Atmospheric Administration.
Tsunamis generally are attributed to large displacements of water, usually from major seismic events such as earthquakes, volcanic eruptions or explosions.
At 1:30 p.m. Thursday, Dec. 20, temperatures dropped by almost 10 degrees in Southwest Florida as barometric pressure momentarily rose by 1.6 millibars. Waves were projected to be about 1.7 feet at 1:30 p.m. but reached 5.04 feet before decreasing rapidly over the next hour.
"Heavy snowfall left many tourists stranded around 17 Mile & Nathu La, Sikkim. Indian Army offered spontaneous help to people providing warm clothing, shelter, hot meals, medical aid & carrying out physical rescue missions," ADG PI, Indian Army's public information wing said in a statement.

Snowmass Ski Area has received 89 inches of snow in November and December as of Friday, according to Aspen Skiing Co. That's more than double the 43 inches for the same two months last season. More snow is forecast for the Aspen area Sunday night, just before 2019 rolls in.
Aspen Highlands has collected 97 inches of snow this November and December compared with 45 inches for the two months last year. That's an increase of 110 percent.

Aerial photo taken on Dec. 30, 2018 shows the view of snow-covered Gan's Grand Courtyard, an ancient architectural complex, in Nanjing City, capital of east China's Jiangsu Province.
In central China's Hunan Province, high-speed trains linking the capital city of Changsha to Guangzhou and Shenzhen suspended operation. All the passenger bus services in the city were suspended due to the snowstorm.
In the neighbouring Hubei Province, some 10,000 subway staff in the capital city of Wuhan began to clean up the snow since 4 a.m. on Sunday at 206 stations and laid sacks and carpets to ensure safety.
This is the third such incident reported this year the state which is very close to Chittagong in Bangladesh.
Earlier in mid-April, at two spots, namely Baishnavpur and Ghagrabasti of Sunroom, lava-like liquid erupted along with fire and gas.
In the recent incident from a few days ago, the local villagers of Jalifa were scared to find lava erupting from the lower portion of the electric pole on the roadside and reported the matter to the fire extinguishing team and local police. A team of firefighters rushed to the spot and tried to spray water and foam, but failed to stop the ongoing eruption that had already burned the spot.
Meanwhile, scientists from the Department of Science, Technology and Environment of the Government of Tripura also visited the spot. After examining the spot and analysing the samples collected from the spot they concluded that the fire, smoke and other materials running out of the ground is due to a fault line that passes through that area beside the displacement of the underground tectonic plates in that region and which is creating huge subsurface heat causing the incident.
Comment: A few months ago a mysterious burning hole with flames shooting out of it was discovered in Midway, Arkansas which baffled geologists. See also:

Activity has recently returned to a moderate level following a hiatus for most of the year.
Explosions like this are typical for Sheveluch- many have happened in the past 25 years as dome-building continues.

Mount Agung volcano erupts, as seen from Kubu, Karangasem Regency in Bali, Indonesia on June 29, 2018.
Mount Agung has been erupting periodically since it rumbled back to life in 2017, when it grounded hundreds of flights and left 120,000 visitors stranded.
On Sunday morning, the volcano - which is about 70 kilometres from the tourist hub of Kuta - sent ash skywards as it erupted for about three minutes, according to the country's volcanology centre.
"Residents near Mount Agung as well as climbers and tourists should not carry out any activity in the danger zone or within a four-kilometre radius from the crater," the centre said in a statement.
The Bureau of Meteorology has reported 1.5m of rainfall since the start of December at Daintree Village — eclipsing a previous December record of 900mm set in 1973.
Cairns Airport has received its highest ever rainfall for the soggy month, with 754.4mm filling the rain gauge, as has Cooktown with 675.6mm.
The bureau has also recorded 888mm of rainfall at Kuranda Railway Station, and 750mm at Innisfail wharf, the highest monthly amounts ever for both locations.
Bureau duty forecaster Lachlan Stoney said they were still expecting the heavy rainfall to continue today, with a severe weather warning issued for a large area across Cape York Peninsula, extending northwest of Cairns.
"It's all associated with the tropical low that's formed in the area," he said.
Governor Edgardo Tallado said they are still having difficulties gathering reports from some towns because power lines are still out after the storm brought rains that flooded parts of the province.
Local disaster officials earlier reported landslides in the towns of Sta. Elena and Labo. Authorities said they are still clearing mud and rock scattered on the roads in these areas.
Tallado said key thoroughfares, like the Maharlika Highway, also remain impassable due to floods. He said at least 70 percent of Daet City, the province's capital, has been affected by floodwater.
