But this time it was an eruption of Anak Krakatau volcano that caused its crater to partially collapse into the sea at high tide, sending waves up to 5 meters (16 feet) high smashing into densely populated coastal areas on Java and Sumatra islands.During the eruption, an estimated 180 million cubic meters, or around two-thirds of the less-than-100-year-old volcanic island, collapsed into the sea.But the eruption didn’t rattle seismic monitors significantly, and the absence of seismic signals normally associated with tsunamis led Indonesia’s geophysics agency (BMKG) initially to tweet there was no tsunami.Muhamad Sadly, head of geophysics at BMKG, later told Reuters its tidal monitors were not set up to trigger tsunami warnings from non-seismic events.The head of Japan’s International Research Institute of Disaster, Fumihiko Imamura, told Reuters he did not believe Japan’s current warning system would have detected a tsunami like the one in the Sunda Strait.“We still have some risks of this in Japan...because there’s 111 active volcanoes and low capacity to monitor eruptions generating a tsunami,” he said in Jakarta.Scientists have long flagged the collapse of Anak Krakatau, around 155 km (100 miles) west of the capital, as a concern.

[5] A 2012 study published by the Geological Society of London deemed it a “tsunami hazard.”.Anak Krakatau has emerged from the Krakatoa volcano, which in 1883 erupted in one of the biggest explosions in recorded history, killing more than 36,000 people in a series of tsunamis and lowering the global surface temperature by one degree Celsius with its ash.Some experts believe there was enough time for at least a partial detection of last week’s tsunami in the 24 minutes it took waves to hit land after the landslide on Anak Krakatau.But a country-wide tsunami warning system of buoys connected to seabed sensors has been out of order since 2012 due to vandalism, neglect and a lack of public funds, authorities say.“The lack of an early warning system is why Saturday’s tsunami was not detected,” said disaster agency spokesman Sutopo Nugroho, adding that of 1,000 tsunami sirens needed across Indonesia, only 56 are in place.“Signs that a tsunami was coming weren’t detected and so people did not have time to evacuate.”.President Joko Widodo this week ordered BMKG to purchase new early warning systems, and the agency later said it planned to install three tsunami buoys on the islands surrounding Anak Krakatau.The cost of covering the country is estimated at 7 trillion rupiah ($481.10 million).
CIGONDONG/JAKARTA, Indonesia (Reuters) - As Indonesia reels from the carnage of yet another natural disaster, authorities around the globe are working on how they can prepare for the kind of freak tsunami that battered coasts west of Jakarta this month.The Dec. 23 tsunami killed around 430 people along the coastlines of the Sunda Strait, capping a year of earthquakes and tsunamis in the vast archipelago, which straddles the seismically active Pacific Ring of Fire.No sirens were heard in those towns and beaches to alert people before the deadly series of waves hit shore.Seismologists and authorities say a perfect storm of factors caused the tsunami and made early detection near impossible given the equipment in place.But the disaster should be a wake-up call to step up research on tsunami triggers and preparedness, said several of the experts, some of whom have traveled to the Southeast Asian nation to investigate what happened.“Indonesia has demonstrated to the rest of the world the huge variety of sources that have the potential to cause tsunamis. Abstract. At a Glance. This can trigger a landslide.
