Philippine volcano 'fireworks' draw tourists as residents flee
News ImageSpectacular lava "fireworks" shooting from its crater are drawing tourists to the Philippines' most active volcano, authorities said Tuesday as scientists warned of a potential dangerous eruption within days. Lava spurting from Mayon volcano lit up the sky overnight Monday in what scientists said was a sign of increasing activity that prompted official calls for evacuation of areas under threat from a major eruption.

The world's longest underwater cave has been found in Mexico
News ImageThe search for the world's most extreme measurements - biggest, highest, tallest - tends to focus above ground, gazing at towering mountains and epic canyons. But the latest global peak statistic has come from under the soil, in the subterranean depths of Mexico's Yucatan Peninsula. There, in the famously porous terrain above which the Mayan civilisation once thrived, is what is now considered to be the planet's longest underwater cave system. A diver exploring Sistema Sac Actun Credit: HANDOUT This is not, technically, an uncovering of a new wonder - more a joining of dots. In recent days, divers have confirmed what had been suspected for a while - that the Sistema Sac Actun (a submerged labyrinth which stretches out for 164 miles) and the Dos Ojos system (shorter, but still impressive at 52 miles in length) are one and the same thing, connected by a previously unsurveyed channel. Sistema Sac Actun Together, this pair of vast limestone wormholes add up to 216 miles of below-the-surface space - a number which makes their combined size greater than that of the Sistema Ox Bel Ha (also in eastern Mexico; 168 miles), which was previously thought to be the yardstick for underwater networks.

The finding has been hailed as "amazing" Credit: HANDOUT The finding has been described as "amazing" by Guillermo de Anda, who is both the director of Gran Acuifero Maya and an underwater archaeologist. It is the result of years of hard work Credit: HANDOUT He says that expanded knowledge of the cave system will allow for a greater understanding of the Maya people, who thrived in the region before prior to the Spanish conquest of Central and South America in the 16th century. "It allows us to appreciate much more clearly how the rituals, the pilgrimage sites and ultimately the great pre-Hispanic settlements that we know emerged," he told Reuters. The Maya considered cenotes to be holy sites Credit: GETTY The Maya held the "cenotes" - giant sinkholes - of their region in high esteem, regarding them as holy sites and portals to communication with the gods. Religious objects and human skeletons have been found at the bottom of some of these sinkholes, including the Sacred Cenote at the historic city of Chichen Itza - leading to the theory that they were used by the Maya for human sacrifice. Tulum caves locator map One of the Yucatan Peninsula's biggest sinkholes is the Gran Cenote - which sits three miles west of the popular tourist town, Tulum. This is also part of the Sistema Sac Actun, and has been used as a gateway for divers charting its many twists and turns.

In 2007, it was revealed that the Sistema Nohoch Nah Chich, previously thought to be separate, was also linked to the Sistema Sac Actun. It is not, however, the longest cave system in the world. Going underground | The world's 10 longest caves While its size makes Sistema Sac Actun the longest underwater cave network, the longest on the planet is the Mammoth Cave complex - which is riddled into the hillsides of southern Kentucky, and is thought to extend for 405 miles.

Massive oil spill spreads in East China Sea, could be world's largest in decades
News ImageWhat could be the largest oil spill since 1989's Exxon Valdez is unfolding in the East China Sea after a deadly and fiery collision between two vessels caused a tanker to sink. All 32 crew members are thought to have died aboard the Iranian vessel "Sanchi," which was carrying about 1 million barrels of condensate. According to Bloomberg News, the ship was transporting hydrocarbon liquid that's a key ingredient for making petrochemicals, including jet fuel. It was headed to the port of Daesan, South Korea when it struck the transport ship "CF Crystal" off China's eastern coast. SEE ALSO: This chatbot wants to cut through the noise on climate science The tanker and its associated oil slick had been on fire for days after the collision. While the fire likely killed all aboard the ship, it was seen by environmental experts as a way to minimize the broader impacts of the spill, since the flames burned off the lightweight condensate on the ocean surface. However, the fire is now out, and the ship has sunk, raising the possibility that the harmful cargo is going directly into the sea. The cargo is different than the crude oil spilled by the Exxon Valdez in 1989, but if all the condensate were to leak into the ocean, it would rank as the biggest spill in decades. Much remains unknown about the fate of the cargo, and therefore similar can be said about what the environmental impacts will be. Reports in recent days are not encouraging, since there is word of a rapidly spreading oil slick on the surface of the ocean. Citing Chinese authorities, Bloomberg reported that the spill expanded from 3.9 square miles to 52 square miles between Sunday and Monday local time. An oil spill in the heavily trafficked East China Sea could have significant environmental repercussions. Humpback whales travel through that area, and heavily fished species such as mackerel and bluefin also spend time in that area. It is virtually certain that much of the condensate went into the sea in solution, and that toxic underwater hydrocarbon plume will injure marine life exposed to it, Richard Steiner,an oil spill specialist based in Alaska, told Bloomberg. Even the burned fraction will leave a toxic residue on the water. Ma Jun, a Chinese environmentalist, was quoted by CNN as saying the spill took place in one of the most productive fishing areas in the country, known as the Zhoushan fishing ground. A handout photo made available by the Transport Ministry of China shows smoke rising from the fire on the Panama-registered tanker 'Sanchi' on Jan. 14, 2018.Image: TRANSPORT MINISTRY OF CHINA HANDOUT/EPA-EFE/REX/Shutterstock"We still need to keep an eye on how these contaminants might be carried by the ocean flow to have the impact on the fishing ground," Jun told CNN. According to Greenpeace International, it's not clear how large this environmental disaster will be, since the amount of condensate that leaked into the water is unknown. "A major concern is that, now that the tanker has sunk, any condensate which did not yet burn off could continue to leak underwater, disperse and break down quite quickly, significantly complicating clean up operations," the environmental advocacy organization stated in a Jan. 15 fact sheet.

Wreck of Dutch Warship Found Buried Beneath Coral
News ImageDivers in the blue waters around the Yucatn Peninsula have discovered three historic treasures: a sunken lighthouse and the remains of an 18th-century Dutch warship and a 19th-century British steamer, according to Mexico's National Institute of Anthropology and History (INAH). The battered wrecks were found near the coastal town of Sisal, Mexico, a modern beach destination that was once a bustling port in the 18th and 19th centuries. The shipwrecks were laden with artifacts, including cannons, cutlery and porcelain, said archaeologist Helena Barba Meinecke, head of the INAH's underwater archaeology of the Yucatn Peninsula.
