About Amanda Clarke

Amanda Clarke studies the nature and causes of explosive volcanic eruptions, with special interest in understanding the behavior of multi-phase fluids.

She gathers data about complex natural systems by observing and monitoring eruptions, and performing stratigraphic and sample analysis. She uses laboratory experiments and numerical models to gain a general physical understanding of real volcanoes, which ultimately aids volcano hazard assessment.

Abstract

LUSI is a mud volcano that is erupting in the urban center of Porong (East Java, Indonesia). Since May 2006, LUSI has emitted hot mud, steam and gas at rates up to 100,000 m3d-1 and has displaced over 40,000 people.

Despite the considerable economic, ecological and human impact of this event, the origin of the fluid that feeds LUSI is poorly understood and only superficially monitored.

The trigger for the eruption is unknown, it’s ongoing eruptive nature is poorly characterized and it’s future behavior can only be guessed at.

We propose a multidisciplinary effort to resolve two broad scientific issues:

1) what is the geologic and hydrologic origin of the water and gas at LUSI mud volcano?

2) how is LUSI evolving and what is the long-term outlook for the eruption?

Establishing the origin of the fluids erupting at LUSI is critical for determining the reservoir conditions controlling the eruption’s longevity and intensity.

We propose detailed chemical and isotopic analysis of the fluid (water/gas) emitted from LUSI and will compare their compositions with those of potential contributing source fluids: river water, seawater, shallow wells and aquifers, meteoric water, fumarole and hot spring fluids from nearby volcanoes (Penanggungan, Arjuno, Bromo/Tengger, Semeru) and, most importantly, pore fluids from underlying geological units at nearby out-crops.

By combining analytical techniques from aqueous/sedimentary geochemistry with monitoring philosophies and technologies from the field of volcanology our team will determine how the mud volcano is linked to the larger geo/hydrothermal system and develop the data necessary to assess and respond to future changes in the eruption.

Broader Impacts :

Beyond the basic scientific questions, this research will provide timely data that the Indonesian management and relief agency (BPLS) desperately needs—our results will have a direct effect on the tens of thousands of people who have been, and will continue to be, affected by this disaster.
