Geological Summary

Gunung Wilis is a solitary volcanic massif surrounded by low-elevation plains on all but its southern side. It was formed during three episodes dating back to the mid Pleistocene. Following destruction of the 2nd edifice, the most recent cone grew during the Holocene. No confirmed historical eruptions are known, although there was a report of an eruption in 1641 CE, the same year as a major eruption of nearby Kelut. Fumaroles and mud pots occur near Lake Ngebel on the lower western flank.

Lake Ngebel, located on the lower western flank of Gunung Wilis, displays fumaroles and mud pots. The lake is viewed here from its SSE shore. Wilis is a solitary volcanic massif surrounded by low-elevation plains on all but its southern side. It was formed during three episodes dating back to the mid Pleistocene, and the most recent cone grew during the Holocene. No historical eruptions are known from Wilis volcano.

The irregular summit profile of Gunung Wilis volcano rises above fields on its eastern flank. This solitary volcanic massif, located between Lawu and Kelut volcanoes, is surrounded by low-elevation plains on all but its southern side. Wilis formed during three episodes dating back to the mid Pleistocene. The youngest edifice is of Holocene age, but no confirmed historical eruptions are known from Wilis volcano. Fumaroles and mud pots occur near Lake Ngebel on the lower western flank of Gunung Wilis.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
