Short summary
Short summary
Some volcanic eruptions are driven by huge gas pockets called Taylor bubbles. Volcanologists use experiments that replicate flow inside volcanic conduits to study these eruptions. We show for the first time that kymography can be used to effectively quantify key Taylor bubble flow features such as: gas volume fraction, gas and liquid slug velocities, bubble length and diameter, falling film thickness, bubble and coalescence event counts, and to indicate steady-state ascent.

Short summary
Pebbles become increasingly rounded during downstream transport in rivers due to abrasion. This study quantifies pebble roundness along the length of two Himalayan rivers. We demonstrate that roundness increases with downstream distance and that the rates are dependent on rock type. We apply this to reconstructing travel distances and hence the size of ancient Himalaya. Results show that the ancient river network was larger than the modern one, indicating that there has been river capture.

Short summary
We develop probabilistic earthquake forecasts that include different spatial information (e.g. fault locations, strain rate) using a point process method. The performance of these models is tested over three different periods and compared with existing forecasts. We find that our models perform well, with those using simulated catalogues that make use of uncertainty in model parameters performing better, demonstrating potential to improve earthquake forecasting using Bayesian approaches.

Short summary
Granular flows are widespread in nature and industry, yet poorly understood. Discrete particle simulations offer detailed insight into their behaviour, but only provide properties of the individual particles, such as velocity and force. To obtain bulk flow quantities relevant to science and engineering, such as pressure or strain rate, we present Pysammos: an open source, user-friendly too to process discrete particle simulation data into continuum fields.
