The volcano that apparently triggered a deadly tsunami in Indonesia late Saturday emerged from the sea around the legendary Krakatoa 90 years ago and has been on a high-level eruption watchlist for the past decade.
Anak Krakatoa (the “Child of Krakatoa”) has been particularly active since June, occasionally sending massive plumes of ash high into the sky and in October a tour boat was nearly hit by lava bombs from the erupting volcano.
Experts say Anak Krakatoa emerged around 1928 in the caldera of Krakatoa, a volcanic island that violently erupted in 1883.
With subsequent lava flows it grew from a submarine setting to become a small volcanic island, with the cone now standing at an altitude of around 300 metres (1,000 feet) above sea level.
Since its birth, Anak Krakatoa has been in a “state of semi-continuous eruptive activity”, growing bigger as it experiences eruptions every two to three years, volcanology professor Ray Cas from Monash University in Australia told AFP.
“Most of the eruptions are relatively small on the scale of explosive eruptions … and there’s also eruptions that produce lava flows,” he added.
Cas said the latest event appeared to be “a relatively small explosive eruption” but could then have triggered or coincided with a submarine event like a landslide or earthquake, causing the deadly tsunami.
No one lives on the island, but the peak is popular with tourists and is a major study area for volcanologists.
When Krakatoa erupted on August 27, 1883 it shot a column of ash more than 20 kilometres (12 miles) into the air in a series of powerful explosions that were heard in Australia and up to 4,500 kilometres away near Mauritius.
The massive cloud of ash plunged the area into darkness for two days. The dust gave rise to spectacular sunsets and sunrises around the world the following year and disrupted weather patterns for years.
The tsunami triggered by the eruption killed more than 36,000 people in one of the world’s worst natural disasters.
Indonesia’s proximity to the junction of three continental plates, which jostle under immense pressure, makes it particularly vulnerable to earthquakes and eruptions.
The archipelago nation has nearly 130 active volcanoes, forming part of the Pacific “Ring of Fire” — an arc of intense seismic activity that stretches from quake-prone Japan through Southeast Asia and across the Pacific basin.
Hundreds of orgs, political and religious leaders demand Pompeo abolish his anti-LGBTQ ‘Commission on Unalienable Rights’
'Harmful to the Global Effort to Protect the Rights of All People and a Waste of Resources'
U.S. Secretary of State Mike Pompeo on Tuesday was sent letters signed by hundreds of human rights organizations, activists, and supporters, along with religious and political leaders demanding he abolish his newly-formed anti-LGBTQ and anti-women "Commission on Unalienable Rights."
Meghan McCain gets schooled after complaining Brett Kavanaugh was treated worse than Al Franken
Meghan McCain noticed the asymmetry in the accusations of sexual misconduct against Al Franken and Brett Kavanaugh, even if she overlooked how those allegations eventually played out.
"The View" tackled a New Yorker piece published by Jane Mayer, who believes the Minnesota Democrat was "railroaded" out of the U.S. Senate over sexual harassment claims, and McCain said Democrats had no choice but to force him to resign.
"Imagine him questioning Brett Kavanaugh at the time," McCain said, "which by the way, the writer who wrote this article, Jane Mayer, wrote a 2018 piece about allegations of Brett Kavanaugh that's been panned because the only corroborating witness said he had heard the story but he didn't remember it now, so it's very tricky."
White supremacists accounted for majority of terror-related arrests in last year: FBI director
FBI Director Christopher Wray told lawmakers on Tuesday that his agency has so far made roughly 100 terrorism-related arrests so far this fiscal year -- and the majority of them are related in some way to the white supremacist movement.
As Washington Post reporter Matt Zapotosky reports, Wray made his remarks about white supremacist terrorists while being questioned by Sen. Dick Durbin (D-IL) during an appearance before the Senate Judiciary Committee.
Despite the fact that white supremacists accounted for a majority of terror-related arrests in the first three quarters of this fiscal year, however, Wray also said that the FBI still considers jihadi-inspired terrorism to be the greater overall threat.
