Threat of powerful eruption at Kuchinoerabu volcano prompts evacuations, Japan
The Japan Meteorological Agency raised the alert level for the Kuchinoerabu volcano in Kagoshima Prefecture from 2 to second highest level of 4 at 01:30 UTC (10:30 JST) on Wednesday, August 15, 2018. This volcano is located on the Kuchinoerabu Island in southwestern Japan, some 1 000 km (620 miles) SW of Tokyo. Its last eruption took place in 2015. The decision to raise the alert was made due to 26 volcanic earthquakes detected within just a few hours. The largest was M1.9 at a depth of 5 km (3.1 miles) in almost the same location as a similar pre-eruption quake that struck 3 years ago. JMA warned that eruption could be powerful enough to cause serious damage to the island's residential area. Level 4 alert means that elderly and disabled people should be evacuated and everyone else should prepare to evacuate. This is the first such warning for this volcano since May 2015 when a powerful eruption forced …

Tropical Cyclone "Ava" hits Madagascar as Category 2 hurricane equivalent

Tropical Cyclone "Ava" made landfall in Toamasina, Madagascar on January 5, 2018 with maximum sustained winds of 167 km/h (103 mph), an equivalent a Category 2 hurricane on Saffir-Simpson Hurricane Wind Scale. Ava is dropping heavy rain on Madagascar for several days now and is expected to continue producing heavy rains, strong winds and flooding as it moves over and along the coast of Madagascar over the next couple of days.
Ava is the first named cyclone of the unusually slow 2017-18 South-West Indian Ocean cyclone season. The season officially began on November 15, 2017, and will end officially on April 30, 2018, with the exception for Mauritius and Seychelles, for which it will end on May 15, 2018.
It reached hurricane strength with maximum sustained winds of 167 km/h (103 mph) around 15:00 UTC on January 5, a couple of hours before it made landfall.
Rising water levels have been observed in the Alaotra Mangoro and Analanjirofo regions, while flooding, interruptions to communications networks and power cuts have been reported in Fokontany Ambinany (Soanierana Ivongo), according to UN OCHA. Preventive evacuations began in Brickaville on January 4.
Météo Madagascar, the national weather service for the country has issued red alerts and yellow alerts that cover a large area of the island's east coast.

Ava's interaction with land has somewhat weakened it and further weakening is expected as it traverses the country, but its heavy rain and strong winds will remain a significant threat to lives and property over the weekend.
There is a very high risk of major flooding and landslides as some places might receive as between 200 and 400 mm (8 - 16 inches) of rain and as much as 600 mm (24 inches) total.

"The mountains east of Antananarivo should protect the capital city from the worst of the cyclone, but enough rain to cause flash flooding can still pour down into the start of the weekend," AccuWeather's senior meteorologist Kristina Pydynowski said.
"As Ava continues to press southward along the coast into Monday, the worst conditions in terms of heavy rain, strong winds and storm surge flooding will focus on Manakara on Saturday, then Taolagnaro on Sunday into Monday. Ava may track far enough away from land later in the weekend to regain severe tropical storm strength. However, the strongest winds may remain offshore in this scenario," she said.
