Volcanic Tracking in an Open Air Lab

 Been monitoring global volcanic activity for some years.   Just loosely involved with monitoring the  La Palma volcanic event by looking at tracking data for current understanding and future predictions.   

Island Becomes Open-Air Lab for Tech-Savvy Volcanologists

Associated Press,  Aritz Parra; Emilio Morenatti,  December 2, 2021

Volcanologists are using cutting-edge technologies to study a rare volcanic eruption on La Palma, one of Spain's Canary Islands. The European Union's Copernicus satellite program generates high-resolution imagery and maps of La Palma to monitor quake-induced deformations, supporting near-real-time tracking of lava flows and ash accumulation. Spanish research vessels are studying the eruption's effects on the marine ecosystem as lava extends beyond the coast. Meanwhile, the Canary Islands' Involcan volcanology institute provides daily reports to guide La Palma civil protection authorities' decisions on whether to evacuate or issue lockdowns amid rising toxic gas levels, based on analyzing terabytes of data from automatic detectors at strategic sites, as well as samples collected in the field.....

Volcanic Eruption Detection

 I like the interaction between drones, sensors, AI and predictive analytics,  so although this example is fairly esoteric, there are probably things to learn from it.  Adding in some predictive risk analysis would be good as well. 

Drone Technology Improves Ability to Forecast Volcanic Eruptions

UCL News

An international team of researchers led by the U.K.'s University College London modified long-range drones that collect data from active volcanoes, in order to better forecast eruptions. The ABOVE project used drone measurements from Papua New Guinea's Manam volcano to demonstrate the ability to gain predictive insights by combining air, Earth, and satellite-based data. Project collaborators co-developed techniques to measure gas emissions from volcanoes via drones, blending in situ aerial measurements with readings from satellites and ground-based remote sensors. Said Alessandro Aiuppa of the University of Palermo, “Ten years ago, you could have only stared and guessed what Manam’s CO2 emissions were. ... '
