I saw a link to https://app.wombo.art/ (https://app.wombo.art/) on twitter and people were posting what they got out of using their research or dissertation titles as a prompt. It is pretty amazing.
For some "light reading" over the winter break, I have enjoyed a read of oral histories of Clarence Allen (Caltech) and Robert Wallace (USGS). EARTHQUAKES, MINERALS AND ME: WITH THE USGS,
The fragility of geologic features, such as precariously balanced rocks (PBRs), can be measured by a simple parameter like α. For the case of a PBR is the smallest of the angles between the vertical
We regulary refer to high resolution topography (HRT) as having Digital Elevation Model (DEM) pixel sizes with their edges less than 1 m. Many raster DEMs derived from airborne laser swath mapping
Our OpenTopography (https://www.opentopography.org/) project was honored at this year's AGU with the Open Science Recognition prize (https://www.agu.org/honors/open-science): "For outstanding
I attended the Tom Hanks, a Remembrance symposium (https://earthquake.usgs.gov/esc/symposium/) at the USGS in Moffett Field Oct. 17, 2024. It was a great chance to remember Tom, reflect on his vast
There have been numerous M4-M5 earthquakes in the Awash area of Ethiopia over the last few months. This is within the Main Ethiopia Rift at its NE end where it begins to open into the Afar. There is
