Earth Changes
It seems that this incident was highly localized, but reading a few comments on Facebook. If this did indeed happen, there's two ways that the weather could have impacted this. One of which is a frost quake. The other possibility is the cold air enhancing the sound.
Frost Quake
Frost quakes, or cryoseisms, are nothing new. In fact, they've been observed/studied since the 1800s. In 2014, there were many reports of these loud booms.
Turi Location Chief Thomas Mose said the two, aged four and 20 years, were struck in their house. Mr Mose said the lightning struck at around 4 pm, leaving their father injured.
The chief said neighbours heard loud thunder and rushed to the homestead but found the two already dead.
The father was taken to Molo Sub-County Hospital.

Aerial photo taken on Jan. 4, 2018 shows the snowy view at the Feicui Lake Park in Hefei, east China's Anhui Province. Many places across China saw snowfall from Wednesday.
Met Eireann was forced to issue and Status Orange alert - and it remain in place until 10pm tonight.
There is also a Status Yellow wind warning in place until 9pm tomorrow.
Storm Eleanor brought brutal gusts and high seas to a number of coastal communities today.
Met Eireann warned there could be flooding along coastal areas, as the weather front causes huge swells.
A forecaster said: "Storm Eleanor will quickly move across the country tomorrow evening and tomorrow night.
"West to southwest winds of mean speeds 65 to 80 km/h, gusting to 110 to 130 km/h, with damaging gusts are expected."
Keep up with all that's going on below.
Comment: Irish Central reports Storm Eleanor battered the shores with winds over 80 mph, with Galway catching the worst. The storm coincided with high tide in Galway City leaving fallen trees and severe flooding in its wake:

Bad weather: Several people were left trapped in a the chairlift in Vorarlberg ski resort in Austria, during a severe snow storm
The footage was shot at the Vorarlberg ski resort in Austria, where several people were left trapped in the lift system as the strong winds suddenly took hold.
Another video filmed nearby shows members of the resort staff climbing up onto the system to try to rescue the skiers, having to hold on as best they can while the snow storm is raging around them.
Elsewhere, both the French and Italian Alps have been on maximum avalanche alert today and several ski resorts closed their runs and lift systems due to the weather.
In France, major resort Val d'Isere closed its runs for the day because of heavy snowfall, while Chamonix said it was shutting many of its lifts as a precautionary measure.

In this Friday, Dec. 29, 2017 photo provided by the Instituto Boto Cinza, a gray dolphin floats dead in the Bay of Sepetiba, on the coast of Rio de Janeiro State, Brazil. Environmentalists say they are trying to figure out why more than 80 gray dolphins have died in less than a month on the coast of Rio de Janeiro state.
The bodies of more than 80 tucuxi dolphins, also known as boto cinza or gray dolphins, have been found in the baffling case.
According to the local Al Dia News, it's the worst mass death of the dolphin this decade. The second-worst was in 2016, when 69 died.
The Instituto Boto Cinza (Gray Dolphin Institute), a non-government organisation which monitors the dolphins, said 88 dolphins have died in the past 18 days - 10 percent of the population in the area.
This is the season for southern noctilucent clouds. Every year around this time, summertime water vapor billows up into the high atmosphere over Antarctica, providing moisture needed to form icy clouds at the edge of space. Sunlight shining through the high clouds produces an electric-blue glow, which AIM can observe from Earth's orbit.
"The current season began on Nov. 19th," says Cora Randall, a member of the AIM science team at the University of Colorado's Laboratory for Atmospheric and Space Physics. "Compared to previous years of AIM data, this season seems to be fairly average, but of course one never knows what surprises lie ahead, particularly since the southern hemisphere seasons are so variable."
Residents took to social media to try to find the source of the noise.
Brenda Curry, a resident of Cherry Log, described what happened close to midnight on Dec. 29: "At first, I heard (and felt) one big explosion. I looked outside, because it sounded like a transformer had blown, or what I imagined a propane tank might sound like if it exploded."
"I didn't see anything," Curry stated of looking outside directly after the noise,"no fire, flames, or smoke."
The storm, currently forming off the coast of Florida before it's expected sweep up the entire eastern seaboard, has been described as a sort of winter hurricane or bomb cyclone due to its rapid formation and heavy impact.
"It's definitely the polar vortex of this year," said Gregg Gallina, a meteorologist at the National Weather Service, in reference to the frigid spell that enveloped much of North America in 2013 and 2014.
Comment: Even if the term bomb has been in use for a while, it's true that year on year strange weather is happening more often and new terminology is created in order to classify it:
- Weather 'bomb' set to go off along US East Coast - Record snowstorms and cold to follow
- US: Polar vortex to bring 'extended period of severe winter weather', amidst already record breaking cold - UPDATE
- Great Lakes storm undergoes bombogenesis, brings down trees and powerlines in Michigan's Upper Peninsula
- Powerful Bering Sea storm undergoes incredible bombogenesis, producing 90 MPH winds in Alaska's Aleutian Islands

A plume of condensation rises off Mount St. Helens, as viewed from the roof of the Cascades Volcano Observatory December 19, 2006, in Vancouver, Washington.
The 3.9 magnitude earthquake was felt in Portland but there were no reported injuries or damage. Since that earthquake there have been 16 more earthquakes, averaging about every half hour with magnitudes from 0.6 to 2.6.
It is common to experience swarms of earthquakes at Mount St. Helens. While it is certainly not a sign of an impending eruption, the earthquakes are a result of an active volcanic system.
Comment: It seems that swarms of earthquakes in the area are a more recent development and were not so common in previous years.
Mount St. Helens is most commonly known for its major eruption in 1980, the deadliest and most economically damaging volcanic event in the history of the United States. The stratovolcano is situated just 96 miles from Seattle and 50 miles from Portland, making an eruption especially dangerous.
Comment: In recent years there has been much activity in the surrounding area and the recent quakes are said to be related to magma movement underground. See also:
