Updates on volcanic activity (Smithsonian)
The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Ijen report has been published on 03 Jun 2020 08:24.
PVMBG reported that on 29 May a gas explosion at Ijen generated a plume that rose 250-500 m above the surface of the lake. According to news articles two sulfur miners heard the explosion from under the water at 1230, 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 Janury-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.
