Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

There are no current tropical storm systems.


Australia – Flooding in Western Australia has submerged homes and roads in the Kimberley region, prompting evacuations. Many communities are likely to be cut off for weeks, authorities warn. Ex-Tropical Cyclone Ellie brought heavy rain to parts of northern Australia in late December 2022, resulting in flooding in areas of northern Queensland, Northern Territory and the Kimberley Region in Western Australia.


Roundup of Global Volcanic Activity – New Activity for the week 28 December 2022 – 03 January 2023

Barren Island – Andaman Islands (India) : The Darwin VAAC reported that ash plumes from Barren Island were identified in satellite images at 2340 on 30 December and 0050 on 31 December rising to 1.5 km (5,000 ft) a.s.l. and drifting SW. A large thermal anomaly was also visible. The ash emissions had dissipated by 0940.

Semisopochnoi – Aleutian Islands (USA) : AVO reported that fresh ash deposits on the flanks of Semisopochnoi’s Mount Cerberus were visible in webcam images during 27-28 December, indicating that activity at the N crater had resumed on 27 December. The deposits extended about 1 km from the vent. Ash plumes were not visible in satellite and webcam images, though a persistent steam plume rising as high as 2.5 km (5,000 ft) a.s.l. may have been carrying minor amounts of ash. Increased seismicity, including seismic tremor, had been recorded during the previous week. Seismic tremor and explosions were recorded during 30-31 December. Satellite and webcam images were obscured by clouds; no plumes were observed above the meteorological cloud deck around 4.7 km (15,000 ft) a.s.l., so any ash emissions would have been at low altitudes. Possible explosions were detected during 31 December 2022-1 January 2023. A small ash deposit extending around 2 km SSW of the N crater were visible in satellite and webcam images. A likely explosion occurred during 1-2 January based on elevated seismicity recorded on local seismometers and an infrasound signal recorded minutes later by an array at Adak. Minor steam-and-gas emissions were visible in partly cloudy satellite images. Low-level explosive activity persisted during 2-3 January, with minor steam emissions and a new ash deposit visible in webcam images.
