Mt. Ruapehu crater lake recording increased temperatures

Temperatures have risen to a 16-year high and surface activity has been reported at Mt Ruapehu's crater lake in the central North Island. A tourist flight over the lake on Saturday afternoon reported vigorous steaming of the surface, which was also disturbed by upwelling bubbles.

GNS duty volcanologist Brad Scott said although these signs hadn't been seen in recent years, the same sort of activity had been observed when temperatures rose over 40-42C. Crater lake temperatures have been rising since late 2015 and have now reached 44C, the hottest recorded since the new lake was established post 2000.

A swarm of volcanic earthquakes reported beneath the surface late last month has stopped, although volcanic tremor has increased slightly this week. Volcanic tremor is always present at Ruapehu, although the level varies and doesn't necessarily indicate an upcoming eruption.

GNS Science volcanologists regularly monitor Mt Ruapehu, an active volcano at the southern end of the Taupo Volcanic Zone.

Dead whale found on the shore of northern Taiwan

Dead whale
A 10-meter long dead whale recently washed up on the shore of Gangnan in Hsinchu City, northern Taiwan, and authorities are till trying to determine the cause of its death, the Coast Guard Administration's (CGA's) local unit said Saturday.

The dead whale was discovered by a coast guard officer on duty on May 4, according to the CGA's Northern Coastal Patrol Office.

Experts from the Taiwan Cetacean Society were called in to examine the whale, which will be dissected to determine the cause of death, the coast guard said.

Mysterious fish die-off at volcanic Lake Toba, Sumatra

Lake Toba is the largest volcanic lake in the world occupying the caldera of a supervolcano on the Island of Sumatra in Indonesia.

Millions of fish were found dead by fishermen between May 3 and May 5, 2016. Officials are unable to find the source of the mass killing but think it is linked to the lack of dissolved oxygen in the water. Could the drop in oxygen content in the north-east of lake Toba be the result of volcanic activity of some kind?

It all started one month ago, when fishermen at Lake Toba started to find dead fish in their nets.

But the mysterious die-offs have suddenly increased beginning of this month, when professional fishermen caught more than 320 tones (May 3, 2016) and then 800 tons (May 5, 2016) of dead fish... In overall about 1500 tones in 3 days! So millions of fish!

Turrialba Volcano in Costa Rica erupting 3 times per hour

Turrialba Volcano erupted at 3:25 p.m. on Monday, May 4, 2015
The Turrialba volcano in central Costa Rica is erupting three times per hour, the National Seismological Network reported Friday.

While volcanic activity remains at the same level of recent days, the tremors accompanying the eruptions are growing less intense, the network said. The ash plume barely rises above the crater's edge, a height of less than 500 meters (1,640 feet).

Turrialba, located some 70 kilometers (43 miles) east of San Jose, entered a phase of increased activity in October 2014, emitting ash, gases and incandescent material. The latest round of eruptions began last week.

Entrances to the national park that surrounds the volcano have been closed as a precaution. Turrialba, which rises 3,340 meters (10,950 feet) above sea level, is Costa Rica's second-highest volcano after Irazu.

Millions of dead fish wash up on Vietnamese coast

Millions of fish have washed up dead along a 125-kilometre stretch of the Vietnamese coast in one of the communist country's worst environmental disasters.

Soldiers have been deployed to bury tonnes of fish, clams and the occasional whale that began dying in early April along the north-central coast, including some popular tourist beaches.

Vietnamese officials facing growing anger over the disaster have not announced the official cause of the deaths, which have affected the livelihoods of tens of thousands of families.

Some officials have suggested it may be toxins or algal blooms known as red tide.

But Vietnamese Prime Minister Nguyen Xuan Phuc has ordered an investigation into how a Taiwanese-owned steel plant received approval to pipe waste directly into the sea.

Cleveland Volcano in Aleutian Islands under heightened alert after explosion

Smoke rises from Cleveland Volcano in the Aleutians on Aug. 8, 2011, in this aerial photo provided by the National Oceanic and Atmospheric Administration. Alaska Volcano Observatory staff raised the volcano's alert level after detecting an explosion Thursday evening.
The Cleveland Volcano in the Aleutian Islands is again under a heightened alert level from the Alaska Volcano Observatory, after researchers there recorded an explosion Thursday evening.

The observatory issued a statement raising the eastern Aleutians volcano's alert level to watch, and its aviation color code to orange, late Thursday.

Researchers said in the statement they detected an explosion at 6:44 p.m. Thursday using both air pressure and seismic data.

"There are no recent satellite views since the detected explosion. However, previous Cleveland explosions have typically produced ash emissions," observatory staff wrote.

Nearly a year ago, scientists recorded a restless period at the volcano on Chuginadak Island, including an explosion -- but no detected ash cloud -- in July.

In March, an eruption at Pavlof Volcano on the Alaska Peninsula sent an ash plume to an altitude of 20,000 feet, coating the nearby village of Nelson Lagoon and disrupting flights across Alaska as the material drifted northeast across Interior Alaska into Canada.

Rare May snowfall in northern Chinese cities

Snow China
Unusual snow in May blanketed the suburb of Beijing and the mountainous region in Chengde City, north China's Hebei Province on Monday, forming an amazingly gorgeous scenery.

Thunder shower hit the Yanqing District of Beijing at dusk on Sunday, with average precipitation reaching 19.1 millimeters from 17:00 on Sunday to 14:00 on Monday. Because of the high altitude of the Haituo Mountain, where the temperature was minus 0 degree Celsius, the rainwater turned to snow.

Elsewhere, the lowest temperature in Wulingshan National Nature Reserve in Chengde City dipped to minus 15 degrees Celsius and the depth of snow was estimated at 18 centimeters.

The current snowfall in May marks the second one in Chengde since 1991, according to local meteorological department.

"It is quite rare to see such snow and it really came all of a sudden," said Wang Jihui, staff member of Wulingshan National Nature Reserve.

7 injured by air turbulence on flight from Dominican Republic

Plane
Seven people were transported to a hospital in Fort Lauderdale, Florida after an Allegiant Air jet hit turbulence returning from Punta Cana, Dominican Republic, first responders told ABC News. The flight was bound for Pittsburgh, Pennsylvania.

Allegiant Air's Flight 7001, a charter operated on behalf of Apple Vacations, encountered "unreported moderate clear air turbulence" Thursday afternoon and was diverted to Fort Lauderdale-Hollywood International airport, according to the company.

When the Airbus A319 landed, emergency personnel assisted four flight attendants and three passengers who had suffered multiple injuries, from bruises and lacerations to head injuries -- none life-threatening.

According to airline spokesperson Jessica Wheeler, a nurse aboard the flight assisted crew members following the turbulence, and all passengers were "ambulatory" by the time they were transported to Broward Health Medical Center.

"Five others were treated at the health clinic in the airport. All of them were Chinese nationals."

The incident occurred when the aeroplane was flying over Borneo, about one hour after flight HX6704, bound for Hong Kong, took off from Bali International Airport.
