Rescue workers sifted through smoldering debris and thick mud Tuesday in search of survivors, a day after a volcano on Indonesia鈥檚 island of Flores and killed at least nine people with its searing lava and ash.

Mount Lewotobi Laki Laki spewed thick brownish ash as high as 2,000 meters (6,500 feet) into the air and threw lava, gravel and ash up to seven kilometers (4.3 miles) from its crater, blanketing nearby communities with tons of volcanic debris and forcing residents to flee.

鈥淭he tremendous roar of the volcano suddenly woke us up that night, followed by flashes of lightning,鈥� said Adelina Nuri, a mother of three who fled along with her relatives from the village of Hokeng. She said they ran through a rain of glowing rocks as they fled.

鈥淚 saw a dazzling light like a glowing giant lamp out from the mountain when volcanic materials began to hit our zinc roof, created noise in my house. We were scared and panicked,鈥� she said.

The National Disaster Management Agency on Tuesday lowered the death toll from an earlier report of 10, saying a victim trapped under tons of debris in a collapsed house who was feared dead was rescued in critical condition. The agency said 63 other people were hospitalized, 31 of them with serious injuries.

More than 2,400 villagers streamed into makeshift emergency shelters after Monday鈥檚 eruption that burned down seven schools, nearly two dozen houses and a convent on the majority-Catholic island, agency spokesperson Abdul Muhari said.

Smoldering debris, thick mud and a power blackout hampered the evacuation and search efforts, said Kensius Didimus, a local disaster agency official.

鈥淲e鈥檒l do everything we can to evacuate villagers by preparing trucks and motorbikes for them to flee at any time,鈥� he said, adding that the debris and lava mixed with rainfall formed thick mud that destroyed the main roads on the island.

Authorities warned the thousands of people who fled the volcano not to return during Tuesday鈥檚 lull in activity. But some were desperate to check on livestock and possessions left behind. In several areas, everything 鈥� from the thinnest tree branch to couches and chairs inside homes 鈥� was caked with ash.

鈥淲e were all ordered to leave our village, because the volcano alert status had reached its highest,鈥� said Andreas, who uses only one name. He and other residents were taken out by truck.

Videos released by the National Search and Rescue Agency showed roads that were covered in heavy gray ash and houses covered by thick gray mud, rocks and uprooted trees.

Adelina Nuri, who fled from the village of Hokeng, said that she had grabbed her children and run out with her husband and other villagers in the darkness, and it turned out that the atmosphere outside was more terrifying, they had to endure a rain of thumb-size glowing rocks and hot ashes.

People were screaming for help and children were crying.

鈥淲e ran and took shelter under a big tree that could protect our heads from hot volcanic materials,鈥� Nuri said, adding that both of her hands were injured from having to protect her children鈥檚 heads.

The country鈥檚 geology agency said a series of eruptions since Thursday had created an accumulation of hidden energy due to a blockage of magma in the crater, which reduced detectible seismic activity while building up pressure.

鈥淭he eruptions have eased pressure that had been building under a lava dome perched on the crater,鈥� said Priatin Hadi Wijaya, who heads the Center for Volcanology and Disaster Mitigation. 鈥淏ut we should anticipate hot ash and debris could tumble down from the crater due to heavy rains.鈥�

Indonesian President Prabowo Subianto has instructed his Cabinet and disaster and military officials to coordinate the response, said Coordinating Minister for Human Development and Culture Pratikno, who like many Indonesians uses a single name.

The country鈥檚 volcano monitoring agency increased the volcano鈥檚 alert status to the highest level and more than doubled the exclusion zone to a seven-kilometer (4.3-mile) radius after midnight on Monday as eruptions became more frequent.

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. 鈥淟aki laki鈥� means husband, while its mate is Lewotobi Perempuan, or woman.

after Mount Lewotobi Laki Laki began erupting, spewing thick clouds and forcing the government to close the island鈥檚 Frans Seda Airport. No casualties or major damage were reported, but the airport has remained closed since then due to seismic activity.

This is Indonesia鈥檚 second volcanic eruption in as many weeks. West Sumatra province鈥檚 , one of the country鈥檚 most active volcanos, erupted on Oct. 27, spewing thick columns of ash at least three times and blanketing nearby villages with debris, but no casualties were reported.

Lewotobi Laki Laki is 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 鈥淩ing of Fire,鈥� a horseshoe-shaped series of seismic fault lines around the Pacific Ocean.
