BMKG says Anak Krakatau eruption shows no signs of triggering a tsunami

Mount Anak Krakatau's latest eruption showed no signs of triggering a tsunami in the Sunda Strait, Indonesia's Meteorology, Climatology and Geophysics Agency said Tuesday.

BMKG Acting Deputy for Geophysics Ardhasena Sopaheluwakan said 20 tsunami gauges and high-frequency radar arrays in Carita and Tanjung Lesung showed a tsunami probability below 50 percent. Monitoring found no abnormal rise in sea levels or significant changes in surface currents.

Wave heights in the strait remained between 0.5 and three meters. Weather was expected to remain sunny to partly cloudy through Sept. 13.

The Volcanology and Geological Hazard Mitigation Center recorded a new Strombolian eruption at 7:49 a.m. Tuesday. It reached a maximum amplitude of 48 millimeters and lasted 19 seconds.

BMKG, the National Disaster Management Agency and the Transportation Ministry deployed five weather-modification sorties using two Cessna Caravan aircraft from Pondok Cabe and Halim Perdanakusuma. One flight dispersed sodium chloride powder, another used liquid calcium chloride as a cloud-condensation agent, and three sprayed water mist. Ardhasena advised people in ash-affected areas to limit outdoor activities and wear masks and protective eyewear.
