Volcanologists plan to install three so-called ''acoustic flow measurement'' devices in rivers originating from the volcano for early detection of volcanic mudflow
areas, build channels or deflection walls to direct the flow around buildings," he said.
The pressure of the accumulated water and heavy downpour triggered the landslide and the mudflow
engulfed three houses along its path.
