LUMAJANG, Indonesia (AP) -- Rescuers were searching for survivors Sunday on the slopes of the highest volcano on Indonesia's island of Java after it was rocked by an eruption that killed at least 13 people, as smoldering debris and thick mud hampered their efforts.
Mount Semeru in Lumajang district in East Java province spewed thick columns of ash more than 12,000 meters (40,000 feet) into the sky, and searing gas and lava flowed down after a sudden eruption Saturday triggered by heavy rains. Villages and nearby towns were blanketed with falling ash and several hamlets were buried under tons of mud from volcanic debris.
Authorities warned the thousands of people who fled the volcano's wrath not to return during Sunday's lull in activity. But some villagers were desperate to check on livestock and possessions left behind. In several areas, everything -- from the thinnest tree branch to couches and chairs inside homes -- was caked with ash.
"There's no life there ... trees, farms, houses are scorched, everything is covered in heavy gray ash," said Haryadi Purnomo of East Java's search and rescue agency. He said that several other areas were virtually untouched.
Search and rescue efforts were temporary suspended on Sunday afternoon because of fears that hot ash and debris could tumble down from the crater due to heavy rains.
The debris and lava mixed with rainfall to form thick mud that destroyed the main bridge connecting Lumajang and the neighboring district of Malang, as well as a smaller bridge, said Thoriqul Haq, the district chief in Lumajang.
The eruption eased pressure that had been building under a lave dome perched on the crater. But experts warned that the dome could still further collapse, causing an avalanche of the blistering gas and debris trapped beneath it.
A thunderstorm and days of rain, which eroded and partly collapsed the dome atop the 3,676-meter (12,060-foot) Semeru, triggered the eruption, said Eko Budi Lelono, who heads the geological survey center.
Semeru, the stratovolcano in shape of a cone, is also known as Mahameru, meaning "The Great Mountain" in Sanskrit. It has erupted many times over the last 200 years. Still, as with other volcanoes -- it is one of 129 under watch in Indonesia, the world's largest archipelago -- more than 62,000 people call Sumeru's fertile slopes home. It last erupted in January, with no casualties.
Indonesia, an archipelago of more than 270 million people, is prone to earthquakes and volcanic activity because it sits along the Pacific "Ring of Fire," a horseshoe-shaped series of fault lines. Currently 54% of the country's nearly 270 million people live on Java, the country's most densely populated area.
Officials said earlier they had hoped they could avoid casualties by closely monitoring the volcano.
National Disaster Mitigation Agency spokesperson Abdul Muhari said 57 people had been hospitalized, mostly with burns, respiratory problems and other injuries. He said rescuers were still searching for seven residents of Curah Kobokan village.
More than 900 villagers streamed into makeshift emergency shelters after Saturday's powerful eruption, but many others defied official warnings and chose to remain in their homes, saying they had to tend to their livestock and protect their property, said Purnomo.
"We'll do everything we can to evacuate them by preparing trucks and motorbikes for them to flee at any time," he said.
Indonesian President Joko Widodo said he instructed his Cabinet ministers and disaster and military officials to coordinate the response.
