Hi! I am a student at SIO using satellite geodesy to study volcanism 🌋 This is a collection of interesting imagery found and processed along the way.

Though beautiful, this algal bloom in Lake Sevan, Armenia is toxic and poses a risk to the local ecology. ⁣ ⁣ ▪ Captured July 31, 2018 by Sentinel 2A ⁣ ⁣


In the spirit of the previous post, here is another salt dome in the Great Salt Desert of Iran. It's a bit of an optical illusion so in case you have a hard time seeing this is a dome (as was the case for me...I originally thought it was a mine), I've also included the Google Earth elevation profile that I made to convince myself 😅 ⁣ ⁣ ▪ Captured August 23, 2018 by Sentinel 2A⁣


Dasht-e Kavir (the Great Salt Desert of Iran) was once covered by an ancient ocean. When this ocean evaporated, it left a thick layer of salt, which was then overlain by sediment. The salt has since been slowly pushing its way up due to its lower density and forms salt domes (diapirs), one of which is seen in this photo. ⁣ ⁣ ▪ Captured August 23, 2018 by Sentinel 2A


Mount Vesuvius is located in the Gulf of Naples and is known for burying Pomeii with a pyroclastic surge during its 79 AD eruption. It's currently considered one of the most dangerous volcanoes in the world due to its violent eruption type and the population density surrounding it. 🏔️⁣ ⁣ ▪Captured January 18, 2018 by Sentinel 2A


Mount Okmok (lower left corner in the first image, mid/upper left in the second) is one of the most active volcanoes in the Aleutian island arc. Usually I avoid cloud cover in finding data to process but these photos happen to have some neat cloud patterns going on 😁⁣⁣ ⁣⁣ ▪ First image captured July 31,2014 by Landsat 8 ⁣⁣ ▪ Second image captured June 16, 2015 by Landsat 8


Musa Bay is a shallow estuary in Iran at the northern end of the Persian Gulf. Dendritic drainage patterns like this form when water erodes flat and homogeneous rock, so there are no zones of structural weakness that get eroded more than others. ⁣⁣ ⁣⁣ ▪First image: two stitched scenes, both captured on July 22, 2018 by Sentinel 2B⁣⁣ ▪ Following images: crops from the first image ⁣⁣


Banks Peninsula on the South Island of New Zealand is the eroded remanants of two shield volcanoes. The crater of one of these forms the Akaroa harbor seen in this photo. The cloudy swirls in the ocean are from loess (windblown silt) deposits that get carried into the ocean by wind and rivers. ⛰️⁣ ⁣ ▪Captured September 16, 2016 by Sentinel 2A


This segment of Glen Canyon is located in central/southern Utah. Like the Grand Canyon, it formed within the last 5 million years by downcutting of the Colorado River. ⁣ ⁣ ▪Captured on May 15, 2018 by Landsat 8
