Ep143 - Lava Dome Growth and Collapse of the 2023 Mayon Volcano Eruption

<p>In this episode, we talk with Mr. Aris Paolo Castro, an instructor at the National Institute of Geological Sciences, UP Diliman, about his study tracking how Mayon Volcano&#39;s lava dome grew and collapsed during its 2023 eruption. Using free satellite images from Landsat and Sentinel-2, the study tracked Mayon&#39;s summit from August 2022 to December 2023 and identified five phases where the dome grew and four phases where it collapsed, cross-checking each observation against PHIVOLCS&#39;s daily activity bulletins.</p><p><br></p><p>📚Reference: Castro AP, Jatulan PM, Principe JA, Tamondong AM. 2026. <a href="https://doi.org/10.5194/isprs-annals-X-5-W4-2025-159-2026" target="_blank" rel="noopener noreferer">Spatiotemporal modeling of lava dome evolution of Mt.
