Abstract Pyroclastic density currents (PDCs) are the most lethal volcanic process on Earth. Forecasting their inundation area is essential to mitigate their risk, but existing models are limited by our poor understanding of their dynamics. Here, we e

Abstract At approximately 09:36 UTC on 27 April 2016, a phreatic eruption occurred on Whakaari Island (White Island) producing an eruption sequence that contained multiple eruptive pulses determined to have occurred over the first 30 min, with a cont

Lahar monitoring on active volcanoes is challenging, and the ever changing environment leads to inconsistent results that hamper a warning systems ability to characterize the flow event properly. Therefore, more data, new methods, and the use of diff

At 23:18 UTC on 18 March 2007 Mt. Ruapehu produced the biggest lahar in New Zealand in over 100 years when a tephra dam holding crater lake water back collapsed causing 1.3x106 m3 of water to flow out and rush down the Whangaehu channel. The outburst

Here, all three components of the seismic signal are applied for use with the amplitude source location (ASL) method to investigate if using all three components yield more accurate results than using just the vertical component. Eight active source
Here, we present data from lahars through the use of a 3-component broadband seismometer, accelerometer, and a video camera installed 3 m from the Lumbre channel on Volcán de Colima, Mexico to understand rheology differences within multiple events,

A frequently applied amplitude source location (ASL) method is here calibrated and optimized by using active seismic sources located at the surface of a dry stream channel. The ASL produced location discrepancies larger than 1.0 km laterally and 500

On 6 August 2012 an eruption of the upper Te Maari vent Tongariro volcano and subsequent debris flow in the Mangatetipua channel created a debris dam and ephemeral lake. The lake reached its maximum volume of 50,000 m3 by 13 October, initiating dam b
