When technology can accessharsh environments.Giovanni Romeo (1), Giuseppe Di Stefano (1), Adriano Mazzini (2), and Alessandro Iarocci (1)(1) Istituto Nazionale di Geofisica e Vulcanologia, Roma, Italy (giovanni.romeo@ingv.it), (2) Centre for Earth Evolution andDynamics (CEED) University of Oslo, Oslo; NorwayExtreme and inaccessible environments are a new frontier that unmanned and remotely operated vehicles cantoday safely access and monitor. The Lusi mud eruption (NE Java Island, Indonesia) represents one of these harshenvironments that are totally unreachable with traditional techniques. Here boiling mud is constantly spewed tensof meters in height and tall gas clouds surround the 100 meters wide active crater. The crater is surrounded by a600 meters circular zone of hot mud that prevents any approach to investigate and sample the eruption site.In the framework of the Lusi Lab project (ERC grant n◦ 308126) we assembled and designed a multipurposedrone to survey the eruption site. The Lusi drone is equipped with numerous airborne devices suitable for use onboard of other multicopters.During the missions three cameras can complete 1) video survey, 2) high resolution photogrammetry of desiredand preselected polygons, and 3) thermal photogrammetry surveys with infra-red camera to locate hot fluidsseepage areas or faulted zones.Crater sampling and monitoring operations can be pre-planned with a flight software, and the pilot is required onlyfor take-off and landing. An automatic winch allows the deployment of gas, mud and water samplers and contactthermometers to be operated with no risk for the aircraft. During the winch operations (that can be performedautomatically) the aircraft hovers at a safety height until the tasks are completed while being controlled by thewinch embedded processor. The drone is also equipped with a GPS connected CO2 and CH4 sensors. Griddedsurveys using these devices allowed obtaining 2D maps of the concentration and distribution of various gassesover the area covered by the flight path.
