UN warns Pacific Ring of Fire is ’active’ as volcanoes erupt across Asia

Meanwhile, volcanoes in Indonesia that started to spew ash and smoke late last year continue to rumble in 2018.

Mount Agung in eastern Bali remains on alert for a major eruption and there have been multiple eruptions this month, according to Twitter alerts from Sutopo Purwo Nugroho, a spokesman for Indonesia's disaster mitigation agency.

In an update on Tuesday, Sutopo wrote: "There have been four eruptions on Jan 23, 2018. Caution. The airport is normal."

Mount Sinabung, which suddenly became active in 2010 after lying dormant for 400 years, sent volcanic ash on villages and farmers' crops in North Sumatra's Karo regency in December last year.

In May 2016, an eruption killed seven people, while a February 2014 eruption left 16 people dead.

Sinabung has been rumbling continuously since 2013. Not a day goes by without an explosion at Sinabung, Sutopo tweeted last week.

Tiada hari tanpa letusan Gunung Sinabung. Letusan terjadi pada 20/1/2018 pukul 07:37 Wib dengan tinggi kolom abu vulkanik 3.000 meter dan lama letusan 545 detik. Kemudian pada pukul 08:03 WIB meletus lagi dengan tinggi kolom abu vulkanik 700 m. #Sumut #volcano #sinabung pic.twitter.com/yzpRCDC77L

Another eruption that made the news in recent months was that of Mount Kirishima, a mountain range in Japan's Kagoshima prefecture. Relatively small explosions sent ash over cities and towns nearby as authorities lifted the alert level to three.
