Cotopaxi Volcano showed an increased activity since April 2015 and evolved into its eventual mild eruption in August 2015. In this work we use records from a broadband seismic station located at less than 4 km the vent that encompass data to December of 2015, detect study low-frequency events. We applied unsupervised learning schemes group identify possible premonitory families. To find these families two-stage process which events were first separated by their frequency content applying...
Abstract Seismic and infrasound multistation ambient‐noise interferometry has been widely used to infer ground atmospheric properties, single‐station autocorrelation seismic also shown potential for characterizing Earth structure at multiple scales. We extend ambient recordings that contain persistent local noise from waterfalls rivers. Across a range of geographic settings, we retrieve relative sound‐speed changes exhibit clear diurnal oscillations consistent with temperature wind...
Monitoring the evolution of lava flows is a challenging task for volcano observatories, especially in remote volcanic areas. Here we present near real-time (every 12 h) and free tool producing interactive thermal maps advance over time by taking advantage data provided FIRMS open-source R software. To achieve this, applied two filters on datasets, one satellite layout (track) another fire radiative power (FRP). determine latter, carried out detailed statistical analysis FRP values nine...
Abstract Here, we present the results of applying diverse data processing and machine learning tools to investigate a very large dataset obtained from single station infrasonic recordings last 10 yr most recent period explosive activity at Tungurahua volcano, Ecuador. To increase quality quantity information extracted set enhance pattern recognition, combined traditional techniques with more ones. We divided investigation into sequential steps: detection, discrimination, cleaning,...
Hazard and risk communication requires the design dissemination of clear messages that enhance people’s actions before, during, after volcanic crises. To create effective messages, components such as message format content, must be considered. Changes in technology are changing way people communicate at an ever-increasing pace; thus, we propose revising basic process to improve dialogue between scientists public. We describe issues during outside crises Ecuador assess possible causes...
