As of January, 2018, where on earth was the most recent deadly volcanic eruption?

Mount Sinabung in North Sumatra, Indonesia, erupted in 1600 AD and then lay dormant until 1912, when lava, gas, and steam escaped from cracks at the summit. On August 29, 2010, the volcano again erupted and an alert for the possibility of a major event was issued. More eruptions, none truly significant, occasionally occurred through the autumn of 2014.

On June 2, 2015, the alert status was heightened. Expecting a possibly major eruption, authorities evacuated 10,000 people on June 26. Nearly a year later, in May of 2016, seven people lost their lives in a “pyroclastic flow” of volcanic material and gases. The “cloud” can move as fast as 700 kilometers (430 miles) per hour, at a temperature of about 1,000 degrees Celsius (1,830 degrees Fahrenheit).

According to Wikipedia’s List of large volcanic eruptions in the 21st Century, Mount Sinabung’s eruption was the last to kill anyone, through January 1, 2018, when the list was edited. The last fatal eruption before this one was on September 27, 2014, when Mount Ontake, on the Japanese island of Honshu, west of Tokyo, killed at least 61 people.
