Since March 2022 when I covered Glen Echo Creek in detail, the city and citizens have been making improvements. Like many Oakland streams, Glen Echo Creek is overgrown with invasive non-natives like broom and ivy plus other opportunistic plants, some of which are all right.

This time we have, among others, some nice papers on recent and not-so-recent seismites, very interesting methodological studies on paleoseismology and tectonic geomorphology, some cool coastal/offshore paleoseismology, and a few articles on earthquake geology from a hazard perspective. Enjoy reading!

Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights section. For July, we are featuring the Planetary and Solar System Sciences (PS), Seismology (SM), and Tectonics and Structural Geology (TS). They are represented by the journals Solid Earth (SE), Geoscientific Model Development (GMD),and Annales Geophysicae (ANGEO).

Ocean tides play a significant role on ocean circulation, coastal processes and mass variations. Tides are generated from the gravitational interaction between Earth, Moon and Sun, which typically results in two high and two low tides observed each day. Satellite observations have vastly expanded our understanding of ocean tides. In 2022, the Surface Water and Ocean Topography (SWOT) satellite was launched, funded by CNES and NASA, and provided a new perspective on the ocean surface and inland water systems. The unique of SWOT comes from its ability to observe the ocean from a two-dimensional perspective, allowing for fine-scale variability of the ocean surface and the observation of process across the land-ocean zone. For more information of SWOT, please visit: https://swot.jpl.nasa.gov/.
