AREAL PHOTOGRAPH (September, 22 2007)

View looking southwest of backhoe managing mud from a levee closest to the central eruption crater. Back hoe sand a crane can aso be seen on the levee in the distance View of a village after it was abandoned due to the mud deposits

Steam emanates from the central eruption crater. The ripples in the highly liquid mud result from pulsations in the eruption View of mud being discharged into the KaliPorong.

Plot showing particle-size distribution (as cumulative volume percent) of LUSI mud samples compared to those of Hurricane Katrina flood sediments (Plumlee and others, 2007a).

Approximate particle-size cutoffs for incidental ingestibility (less than 250 µm), inhalability through nasal breathing (less than 10 µm), and respirability through nasal breathing (less than 2.5 µm) are from sources listed in Plumlee and others (2006). Oral breathing, such as during exercise or very dusty conditions, results in the shift of inhalable and respirable particles to somewhat coarser particle sizes.

SEM photomicrographs of the LUSI mud sample. The mud was suspended in isopropanol to declump particles, and then the particles were collected by filtering the water suspension through filter paper. Note scale bars vary between A-C. A. Typical view of many particles. B. Typical smectite clay particle. C. Aggregate of many small pyrite (iron disulfide) crystals

The basic structure and elements of a mud volcano system

Changes in Insar's data from June 2006 to February 2007, there was a vertical displacement as subsidence and uplift in the LUSI area and showed a decreasing trend InSAR using ALOS/PALSAR data. In: Presented at FRINGE 2007 workshop, November 2007, Frascati, Italy. Workshop presentation available from: http://earth.esa.int/workshops/fringe07/ presentations. html/ Workshop proceedings are in press

The structural geology model at LUSI MV area. Horizontal displacement measured by GPS survey from June 2006 - March 2007 indicate the major trends are NW-SE and NE-SW as seen in the rose diagram. (A) Watukosek fault escarpment (B) The slickenside on recent sediment at LUSI MV area with trending NE-SW (C) Railway bended at westernpart of LUSI with trending NW-SE (D) Tear fault in watukosek fault zone with trending NE-SW (E) Thrust fault at north side of main vent

Geological cross section that in line with watukosek faults that across fore arc basinvolcanic complex and back arc basins. At the incision interpreted there are potential heat sources that are still stored and some have appeared as hydrothermal manifestations in the back arc basin or in the kendeng and rembang zone
