Kim described it as a "straight rainbow just hovering in the sky at Arab City Hall."

Cindy Bryan saw something similar, too, in Fort Payne -- about 45 miles east as the crow flies.

While it looks like a rainbow and it belongs in the atmospheric optics family, this phenomenon is actually a circumhorizon arc. It is a halo that is located beneath the sun, parallel to the horizon.

Circumhorizon arcs occur when sunlight passes through plate-oriented ice crystals suspended in the sky; these ice crystals are what make up high, thin clouds like cirrus and cirrostratus clouds, located about 16 thousand to 50 thousand feet above the ground.

As the sun rises higher in the sky, sunlight enters a portion of the ice crystal that is nearly vertical before exiting out the flat, horizontal bottom. As it does so, the light refracts and produces bright, prismatic colors. Often, the colors are more vibrant and pure than those seen in a rainbow.

Three killed by lightning strikes in Thailand and Cambodia; 30 dead for the latter in first 5 months of 2016

Lightning strike
Two Cambodians working on a farm in Thailand's Rayong province were killed by lightning on Monday.

A border communications officer, who asked to remain anonymous, said the victims were a mother and a son from Battambang province.

Their bodies were sent to Cambodia yesterday via border checkpoint 400, to be handed over to their relatives for a funeral. Their names were not immediately available.

Separately, 64-year-old farmer Hoern Plorng was struck down while cutting bamboo during a storm in O'Chrou district in Banteay Meanchey yesterday, according to district police chief Ee Cheng Sokha.

National Committee for Disaster Management (NCDM) spokesman Keo Vy said yesterday that Plorng's death was the 30th lightning fatality in Cambodia since the start of the year.

According to a May 17 NCDM report, lightning this year has killed 30 and injured 35 people, compared to 18 deaths and seven injuries in the first five months of 2015.

Second powerful earthquake of the day hits Ecuador: Magnitude 6.8

Two powerful earthquakes jolted Ecuador on Wednesday, a magnitude 6.7 early morning temblor followed by a 6.8 shake near midday.

The extent of damage from the second quake was not immediately clear, though President Rafael Correa announced on Twitter some areas along the coast had lost power and said schools would be cancelled nationwide as a precaution. The first caused little serious damage.

Both appeared to be aftershocks of a magnitude 7.8 quake a month earlier.

The U.S. Geological Survey said the second quake hit at 11:46 a.m. (12:46 p.m. EDT; 1646 GMT) and was centered along the coast below land about 15 miles (24 kilometers) north of the city of Rosa Zarate.

The earlier quake was centered less than 10 miles (about 10 kilometers) away and struck shortly before 3 a.m. local time. Both are less than 100 miles (155 kilometers) west-northwest of the capital, Quito.

Second whale washes up on the beaches of Spain within a week

Following the discovery last week of a live whale calf on the beach of Punta del Moral in Ayamonte, in the province of Huelva (Andalucía), a second beached whale was found on the Atlantic coast on Tuesday in Matalascañas, around a hundred kilometres further east.

The animal, which measured 9.5 metres in length, was found dead on the beach of Asperillo, and despite the fact that this incident occurred so close to Ayamonte and such a short time afterwards the Department of the Environment in the regional government reports that there is no reason to conclude that there is any relation between the two deaths.

The responsibility of removing the dead whale from the beach lies with the Town Hall of Almonte.

Evidence proves widespread Texas earthquakes have been triggered by oil and gas operations

Earthquakes triggered by human activity have been happening in Texas since at least 1925, and they have been widespread throughout the state ever since, according to a new historical review of the evidence published online May 18 in Seismological Research Letters.

The earthquakes are caused by oil and gas operations, but the specific production techniques behind these quakes have differed over the decades, according to Cliff Frohlich, the study's lead author and senior research scientist and associate director at the Institute for Geophysics at the University of Texas at Austin.

Frohlich said the evidence presented in the SRL paper should lay to rest the idea that there is no substantial proof for human-caused earthquakes in Texas, as some state officials have claimed as recently as 2015.

Whale carcass found on beach in Egypt

Civil Protection personnel pulled out the carcass of a dead whale that had washed ashore on a beach approximately ten kilometers west of Egypt's northwestern city of Marsa Matrouh, privately-owned al-Wafd reported.

The whale, which was first spotted by city locals who then reported it to the authorities, is around 15 meters long and weighs seven tons. An earlier version of this article had cited the general director of the Fisheries Authority in Matrouh as saying the animal is a humpback whale native to the Atlantic Ocean. However, its appearance suggests it is a sperm whale.

He went on to say that the whale had come to the warm waters of the Mediterranean to find a mate but was stranded due to the shallow waters outside Marsa Matrouh, which have a depth of no more than ten meters.

In video clips posted on social media, the whale carcass can be seen bobbing back and forth in the salty water, while a number of bystanders watch and take pictures.

Sri Lanka landslide buries three villages, 300 - 400 people feared dead

Massive landslides triggered by torrential rains crashed down onto three villages in the central hills of Sri Lanka, and more than 200 families were missing Wednesday and feared buried under the mud and debris, the Sri Lankan Red Cross said.
A massive landslide in a remote area in western Sri Lanka has buried three villages, with rescue workers still looking for 200 missing families.

The landslide struck the central Aranayake area Tuesday night following three days of heavy rain described as the most severe since 2010.

Authorities said Siripura, Pallebage and Elagipitya villages, located about 72km from the capital Colombo, were buried and that rescue operation has become difficult as electricity has been cut off.

Red Cross Director General Neville Nanayakkara said around 300-400 people are feared to have died in the Aranayaka landslide.

Rescue operations has been further hampered as reaching the mountainous areas is difficult.

"Rescuers would have to get there by foot and start digging with their hands before we can get any heavy equipment in to the site," said Sri Lanka Red Cross Communications Manager Mahieash Johnny.

USGS: 6.7 earthquake strikes western Ecuador

A 6.7 magnitude earthquake has struck Ecuador, the US Geological Survey reports. The country has been recently hit by a series of devastating quakes that killed dozens of people.

The quake took place 34km from the town of Rosa Zarate and 35km from the town of Muisne, which already suffered from previous tremors.

According to the USGS, the quake was at a depth of 32km.

More than 600 people were killed and over 2,500 injured in a 7.8-magnitude earthquake that struck off the Ecuadorian coast in April. That quake was followed by a series of strong aftershocks. The disaster ravaged coastal towns and left thousands of households without power.
