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.

This is a looped timelapse of urban sprawl in Las Vegas from 1984 to 2018. It was composed of 33 individual Landsat 8 and Landsat 5 images that were each cropped to the same region. I tried my best to get the brightness/contrast/hue to match in each but it's amazing how much variety the Landsat data has, even when selecting each dataset from the same time of year. Also interesting to watch the water level of Boulder Basin (part of Lake Mead) change through the years 😀

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

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
