Today is the 5 year anniversary of the 2019 Ridgecrest earthquakes (July 4th & 5th). There are several #lidar and photogrammetric (space-based and UAS) datasets available from OpenTopography covering the area impacted by this event: portal.opentopography.org/da…
15 Jun 2020
Updated release of M6.4 & M7.1 Ridgecrest earthquake sequence #lidar. Release adds data over Naval Air Weapons Station China Lake, and now includes the main surface fault ruptures. Data collected by @NCALM_UH, funded by @USGS & @NSF.

Recent publication by @neotectonic et al., investigates earthquake hazards in the Greater Caucasus Mountains of Azerbaijan using satellite imagery-derived topography & paleoseismic trenching. Topographic data are available on OpenTopography at: doi.org/10.5069/G9RJ4GPJ #opendata
ALT Point cloud colored by elevation over Agsu, Azerbaijan

We've added an enhancement for topographic differencing results that allows users to visually compare the change between two overlapping datasets w/ a slider. 📷: Quarry near Washington, Indiana comparing 2013 & 2018 #lidar datasets. Info & more examples: opentopography.org/news/slid…
