Ijen volcano (East Java, Indonesia): weekly volcanic activity report 27 May-2 Jun 2020
Thursday Jun 04, 2020 08:03 AM | BY: MARTIN
Crater lake at Ijen volcano (image: @lubihph/twitter)PVMBG reported that on 29 May a gas explosion at Ijen generated a plume that rose 820-1,640 ft (250-500 m) above the surface of the lake.
According to news articles two sulfur miners heard the explosion from under the water at 12:30 local time, which created 3 m high waves in the lake. The miners ran but one tripped and fell into the lake. Search efforts were unsuccessful after three hours and, due to weather conditions and an increased amount of gas in the crater area, had to be suspended.
PVMBG noted that patterns of various types of earthquakes did not indicate increased activity during 17 January-29 May.
The temperature of the lake water fluctuated between 24.5 and 40.3 degrees Celsius. A lot of rain in the past few months increased the volume of the lake, possibly contributing to a disruption in the system, though these seasonal changes were within normal ranges at the volcano.
The Alert Level remained at 1 (on a scale of 1-4), and residents and visitors were advised to not approach the crater rim or descend to the crater floor.
