Fires detected on infrared satellite imagery, but no volcanic activity

MODIS thermal alerts at Kawi-Butak during 2001 and 2002 occurred only in August and October 2002 mostly to the SE of the summit. These almost certainly represent fires rather than volcanic events. The biggest detected alert occurred on 12 October and was characterized by seven alert-pixels with maximum alert ratio of -0.298. These alert pixels were in a group including the summit and the N flank, and are the best candidate for an eruption, though it is unlikely that an eruption of the kind required to trigger such an alert (a significant lava dome or flow) would have gone unreported. The Volcanological Survey of Indonesia confirmed that there was no eruption at Kawi-Butak on 12 October 2002 and that the thermal alert was indeed caused by a bush fire.

Geological Summary

The broad Kawi-Butak volcanic massif lies immediately east of Kelut volcano and south of Arjuno-Welirang volcano. The 2551-m-high Gunung Kawi was constructed to the NW of 2868-m-high Gunung Butak. No historical eruptions are known from either volcano, but both are primarily of Holocene age.

The Global Volcanism Program is not aware of any Holocene eruptions from Kawi-Butak. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Kawi-Butak page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The broad Kawi-Butak volcanic massif, seen here from the ENE along the rim of Tengger caldera, lies immediately east of Kelut volcano and south of Arjuno-Welirang volcano. The 2551-m-high Gunung Kawi (right) was constructed to the NW of 2868-m-high Gunung Butak (center).

The broad Kawi-Butak volcanic massif rises above rice paddies below its SW flank. The forested volcano lies immediately east of Kelut volcano and south of Arjuno-Welirang volcano. The high point of the complex is flat-topped 2868-m-high Gunung Butak on the right horizon. The 2551-m-high Gunung Kawi (left-center) was constructed to the NW of Butak. No historical eruptions are known from either volcano, but both are primarily of Holocene age.

Three young volcanoes in eastern Java are seen in this aerial view from the NE. The Arjuno-Welirang massif lies at the left-center, with 3339-m-high Gunung Arjuno forming the high point of the complex and light-colored Gunung Welirang to the NW (right). In the background is the Kawi-Butak massif, with 2868-m-high Gunung Butak forming the high point and Gunung Kawi to its right. The smaller conical peak of Penanggungan rises above lowlands in the foreground.

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.
