Indonesia’s Mount Tambora volcano alert level heightened
Dompu - Increased rumblings this month from Mount Tambora on Indonesia’s Sumbawa Island are forcing residents to take the mountain seriously, with authorities there raising the volcano alert to its second-highest level.
“On August 30, we recorded seven volcanic earthquakes and since Sept. 8 the frequency of the quakes rose substantially, to between 12 and 16 per day,” said Husnuddin, head of the West Nusa Tenggara Disaster Mitigation Agency, (BNPB), the Jakarta Globe reports.
Mount Tambora has the distinction of having the world’s deadliest eruption which killed at least 71,000 people, with some estimates as high as 90,000. Between 11,000-12,000 were killed by the eruption itself while tens of thousands more died from the ensuing starvation and disease associated with volcanic fallout which created the “Year Without a Summer” in 1816, a summer which greatly impacted the Northern Hemisphere, including North America and Europe.
The heightened alert status means an eight-kilometer exclusion zone has been imposed. “We fear there will be toxic gas as a direct result of the increased activity,” said Abdul Haris with the Mount Tambora observatory, according to Jakarta Globe.
The BNPB has conducted meetings with leaders of the three districts surrounding Mount Tambora - Bima, Dompu and Sumbawa. In Pekat and Tambora, two subdistricts of Dompu, evacuation routes were being discussed in case the alert is raised to its highest level. Four villages located in Pekat and Tambora lie within eight kilometers of the volcano.
Indonesia is situated in the Pacific Ring of Fire and has around 130 active volcanoes. Mount Tambora lies about 200 miles north of the ring's Java Trench.

History’s deadliest volcano comes back to life in Indonesia, sparking panic among villagers

MOUNT TAMBORA, Indonesia — Bold farmers in Indonesia routinely ignore orders to evacuate the slopes of live volcanoes, but those living on Tambora took no chances when history’s deadliest mountain rumbled ominously this month.
Villagers like Hasanuddin Sanusi have heard since they were young how the mountain they call home once blew apart in the largest eruption ever recorded — an 1815 event widely forgotten outside their region — killing 90,000 people and blackening skies on the other side of the globe.
So, the 45-year-old farmer didn’t wait to hear what experts had to say when Mount Tambora started being rocked by a steady stream of quakes. He grabbed his wife and four young children, packed his belongings and raced down its quivering slopes.
“It was like a horror story, growing up,” said Hasanuddin, who joined hundreds of others in refusing to return to their mountainside villages for several days despite assurances they were safe.
“A dragon sleeping inside the crater, that’s what we thought. If we made him angry — were disrespectful to nature, say — he’d wake up spitting flames, destroying all of mankind.”
The April 1815 eruption of Tambora left a crater 7 miles (11 kilometers) wide and half a mile (1 kilometer) deep, spewing an estimated 400 million tons of sulfuric gases into the atmosphere and leading to “the year without summer” in the U.S. and Europe.
It was several times more powerful than Indonesia’s much better-known Krakatoa blast of 1883 — history’s second deadliest. But it doesn’t share the same international renown, because the only way news spread across the oceans at the time was by slowboat, said Tambora researcher Indyo Pratomo.
In contrast, Krakatoa’s eruption occurred just as the telegraph became popular, turning it into the first truly global news event.
The reluctance of Hasanuddin and others to return to villages less than 6 miles (10 kilometers) from Tambora’s crater sounds like simple good sense. But it runs contrary to common practice in the sprawling nation of 240 million — home to more volcanoes than any other in the world.
Even as Merapi, Kelut and other famously active mountains shoot out towering pillars of hot ash, farmers cling to their fertile slopes, leaving only when soldiers load them into trucks at gunpoint. They return before it’s safe to check on their livestock and crops.
Tambora is different.
People here are jittery because of the mountain’s history — and they’re not used to feeling the earth move so violently beneath their feet. Aside from a few minor bursts in steam in the 1960s, the mountain has been quiet for much of the last 200 years.
Gede Suantika of the government’s Center for Volcanology said activity first picked up in April, with the volcanic quakes jumping from less than five a month to more than 200.
“It also started spewing ash and smoke into the air, sometimes as high as 1,400 meters (4,600 feet),” he said. “That’s something I’ve never seen it do before.”
Authorities raised the alert to the second-highest level two weeks ago, but said only villagers within 2 miles (3 kilometers) from the crater needed to evacuate.
