Indonesia’s Mount Lewotobi Laki Laki volcano spewed towering columns of hot ash high into the air Saturday, days after a huge eruption killed nine people and injured dozens of others.
Activity at the volcano on the remote island of Flores, in East Nusa Tenggara province, has increased since Monday’s initial eruption. On Thursday, authorities expanded the danger zone as the volcano erupted again.
Friday's activity saw the largest column of ash so far recorded at 10 kilometers (6.2 miles) high, Hadi Wijaya, the head of the Center for Volcanology and Geological Disaster Mitigation, told a news conference.
Wijaya said volcanic materials, including smoldering rocks, lava, and hot, thumb-size fragments of gravel and ash, were thrown up to 8 kilometers (5 miles) from the crater on Friday.
There were no casualties reported from the latest eruption as the 1,584-meter (5,197-foot) volcano shot billowing columns of ash at least three times Saturday, rising up to 9 kilometers (5.6 miles), the volcano monitoring agency said.
Authorities increased Lewotobi Laki Laki’s alert status to the highest level since Monday, and expanded the danger zone on Thursday to a radius of 8 kilometers (5 miles) on the northwest and southwest sides of the mountain slope.
“We are still evaluating how far the (danger zone) radius should be expanded,” Wijaya said. Hot clouds of ash “are currently spreading in all directions.”
The volcanic activity has damaged schools and thousands of houses and buildings, including convents, churches and a seminary on the majority-Catholic island.
Craters left by rocks falling from the eruptions measured up to 13 meters (43 feet) wide and 5 meters (16 feet) deep, experts found.
Authorities have warned the thousands of people who fled the area not to return home, as the government planned to evacuate about 16,000 residents out of the danger zone. The series of eruptions throughout the week have already affected more than 10,000 people in 14 villages, with more than half moving into makeshift emergency shelters, The Associated Press reported.
A total of 2,384 houses and public facilities were damaged or had collapsed after tons of volcanic material hit the buildings, said Kanesius Didimus, head of a local disaster management agency. It also destroyed a main road connecting East Flores district where the mountain is located to neighboring Larantuka district.
Rescue workers, police and soldiers searched devastated areas to ensure all residents had been moved out from the danger zone. Logistic and relief supplies were provided to about 10,700 displaced people in eight evacuation sites as of Saturday.
The National Disaster Management Agency said residents of the hardest-hit villages would be relocated within six months, and each family waiting to be rehoused would be compensated 500,000 rupiah ($32) per month.
About 6,500 people were evacuated in January after Mount Lewotobi Laki Laki began erupting, spewing thick clouds and forcing the government to close the island’s Fransiskus Xaverius Seda Airport. No casualties or major damage were reported, but the airport has remained closed due to seismic activity.
Three other airports in neighboring districts of Ende, Larantuka and Bajawa have been closed since Monday after Indonesia’s Air Navigation issued a safety warning due to volcanic ash.
Lewotobi Laki Laki is one of a pair of stratovolcanoes in the East Flores district of East Nusa Tenggara province, known locally as the husband-and-wife mountains. “Laki laki” means man, while its mate is Lewotobi Perempuan, or woman. It's one of the 120 active volcanoes in Indonesia, an archipelago of 280 million people. The country is prone to earthquakes, landslides and volcanic activity because it sits along the “Ring of Fire,” a horseshoe-shaped series of seismic fault lines around the Pacific Ocean.

African elephants are Earth's largest land animals, remarkable mammals that are very intelligent and highly social. They also are in peril. Fresh evidence of this comes in a study that documents alarming population declines at numerous sites across the continent over about a half century.

Researchers unveiled on Monday what they called the most comprehensive assessment of the status of the two African elephant species - the savanna elephant and forest elephant - using data on population surveys conducted at 475 sites in 37 countries from 1964 through 2016.

The savanna elephant populations fell by about 70% on average at the surveyed sites and the forest elephant populations dropped by about 90% on average at the surveyed sites, with poaching and habitat loss the main drivers. All told, there was a 77% population decrease on average at the various surveyed sites, spanning both species, Reuters reported.

Elephants vanished at some sites while their populations increased in other places thanks to conservation efforts.

"A lot of the lost populations won't come back, and many low-density populations face continued pressures. We likely will lose more populations going forward," said George Wittemyer, a Colorado State University professor of wildlife conservation and chair of the scientific board of the conservation group Save the Elephants, who helped lead the study published in the journal Proceedings of the National Academy of Sciences.

Poaching typically involves people killing elephants for their tusks, which are sold illegally on an international black market driven mostly by ivory demand in China and other parts of Asia. Agricultural expansion is the top factor in habitat loss.

The forest elephant population is estimated to be about a third that of savanna elephants. Poaching has affected forest elephants disproportionately and has ravaged populations of both species in northern and eastern Africa.

"We have lost a number of elephant populations across many countries, but the northern Sahel region of Africa - for example in Mali, Chad and Nigeria - has been particularly hard hit. High pressure and limited protection have culminated in populations being extirpated," Wittemyer said.

But in southern Africa, elephant populations rose at 42% of the surveyed sites.

"We have seen real success in a number of places across Africa, but particularly in southern Africa, with strong growth in populations in Botswana, Zimbabwe and Namibia. For populations showing positive trends, we have had active stewardship and management by the governments or outside groups that have taken on a management role," Wittemyer said.

The study did not track a continent-wide population tally because the various surveys employed different methodologies over different time frames to estimate local elephant population density, making a unified head count impossible. Instead, it assessed population trends at each of the surveyed sites.

A population estimate by conservationists conducted separately from this study put the two species combined at between 415,000 and 540,000 elephants as of 2016, the last year of the study period. It remains the most recent comprehensive continent-wide estimate.

"The loss of large mammals is a significant ecological issue for Africa and the planet," said conservation ecologist and study co-author Dave Balfour, a research associate in the Centre for African Conservation Ecology at Nelson Mandela University in South Africa.

The world's third extant elephant species, the slightly smaller Asian elephant, faces its own population crisis, with similar factors at play as in Africa.

Of African elephants, Wittemyer said, "While the trends are not good, it is important to recognize the successes we have had and continue to have. Learning how and where we can be successful in conserving elephants is as important as recognizing the severity of the decline they have experienced."

Wittemyer added of these elephants: "Not only one of the most sentient and intelligent species we share the planet with, but also an incredibly important part of ecosystems in Africa that structures the balance between forest and grasslands, serves as a critical disperser of seeds, and is a species on which a multitude of other species depend on for survival."
