Our paper on Taftan Volcano went global! 📺📰
Couldn’t ask for a better academic & science farewell. 👋🌋!

💡✅ Hence, we propose two internal mechanisms:
1️⃣ Hydrothermal alteration → lower permeability → trapped gas → pressure buildup → uplift → degassing
2️⃣ Small deep magma input → volatile release → shallow pore-pressure increase.
⛰️Both imply Taftan is more active than previously thought

📅 Results shows that Uplift started mid-July 2023 (±4 days) and ended mid-May 2024 (±9 days).
East flank deformation began later but ceased earlier; summit uplift lasted about 10 months and coincided with several gas-emission events. 🌋

🕒 To determine the precise timing of the unrest, including its start and end times, we utilized a hyperbolic tangent model applied to a refined set of time series pixels from the summit and both flanks. The findings indicate a gradual onset, acceleration, and recovery in deformation behaviour.

Introduce 🌫️ Common-Mode Filtering (CMF) to mitigate spatially correlated atmospheric signals by averaging time series of non-deformed pixels and subtracting them from the target point. Results show an improvement in time series accuracy of up to 50%, aiding in the precise analysis of unrest timing.

📡Sentinel-1 InSAR reveals ~9 cm of vertical uplift centered on the active fumarole fields.
Modeling with a Mogi source indicates a shallow pressure source at 0.5–0.6 km depth, right beneath the summit

Taftan is the only one with persistent fumarolic activity.

Unveiling nature's masterpiece!😍 This small salt diapir in central Iran, its shape mimicking a brain🧠, is Earth’s own neural network rising from the sands🌍. Its activity was revealed for the first time using InSAR 2019🛰️. Learn more! 👉

Profiles of displacement rate in the vertical directions (red color) versus topography. The red curves and left y-axis correspond to the vertical displacement rate, and the black curves and the right y-axes correspond to altitude.

This incredible salt structure, with its fascinating shape, is active—can you imagine? Yes, it is! Located in central Iran, it’s part of some of the most unique and amazing salt diapirs in the world. In 2021, we were the first to reveal its activation using InSAR
Salt diapirs never fail to amaze me!

🌋 Paper Alert! 🛰️
Excited to share our new paper on the 2018 Sierra Negra #volcano eruption! We used #InSAR, #optical-flow, & #pixel-offset-tracking to understand how surface deformation reveals the volcano’s magma dynamics. Check out the highlights below!
