Summary: This study conducts a comprehensive analysis of gravity, magnetic, and land surface temperature data to investigate the geothermal potential of the Lunayyir volcanic field in western Saudi Arabia. The gravity data reveal a series of gravity anomalies that indicate the presence of subsurface geologic structures similar to other geothermal areas. The magnetic data show a relatively low magnetic susceptibility, consistent with the presence of volcanic rocks and shallow heat sources. Furthermore, satellite data indicates higher land surface temperature in 2007, suggesting volcanic activities in the subsurface. These findings highlight the importance of combining different geophysical datasets for a better understanding of underground geology and geothermal systems.

Summary: Recent conceptual geological frameworks emphasize that the small volume eruptions, resulting volcanic geology and architecture in continental monogenetic volcanism are sensitive to variations in external or environmental conditions. Understanding the drivers of transitions in explosive to effusive behavior within the short timescales of eruptions is essential to accurately assess volcanic hazards. Wiri Mountain Volcanic Complex in the active Auckland Volcanic Field provides a unique opportunity to study the growth and evolution of a volcanic complex. A high-resolution stratigraphic study was conducted to determine changes in eruptive style and their driving forces. The findings highlight the importance of both external and internal conditions in controlling eruption style variations and the formation of complex monogenetic volcanoes.

Summary: Monogenetic volcanoes are characterized by a single eruptive phase, short-lived eruptions, and complex landforms. Understanding the evolution of eruptive styles is important for understanding the formation of these complex systems. The classification of complex monogenetic volcanic centers is significant for understanding past and future volcanoes. This study reconstructs the volcanic history of the Waitomokia Volcanic Complex, highlighting the complexity of simultaneous activity in different areas.

Summary: Developing and exploring geothermal resources is necessary for achieving sustainable development and clean renewable energy worldwide. Geothermal energy is crucial for meeting the future environmentally friendly energy demand. The Rahat Volcanic Field in Saudi Arabia, the oldest and longest Cenozoic Volcanic Field, was studied using geological and geophysical data to identify potential geothermal resources. Analysis of gravity and magnetic data, as well as rock samples, led to the discovery of a geothermal anomaly beneath the historic eruption site with a surface footprint of about 35 km².

Summary: Geoheritage plays a crucial role in developing strategies for natural hazard resilience, with a focus on raising global awareness and communicating importance to society. Urban areas like Auckland are facing challenges in preserving volcanic geoheritage, with abandoned quarry sites potentially serving as key locations for outreach and research. The rapid loss of volcanic geoheritage in Auckland contrasts with positive examples from older volcanic regions like the Bakony-Balaton UNESCO Global Geopark in Hungary.

Summary: This article describes the construction of the Millennium Tower in San Francisco, including the monitoring of foundation settlements and building tilt, as well as the soil deformation mechanisms. The results show that both foundation settlements and building tilt are related to variations in horizontal and vertical stresses.

Summary: Phreatomagmatism, caused by the interaction of erupting magma and groundwater, is a common phenomenon in monogenetic volcanism. This study found that pressure variations inside the eruptive conduit play a major role in controlling phreatomagmatism, rather than the lithological and hydraulic properties of aquifers.

Summary: This study presents updated reconstructions of watershed runoff to San Francisco Estuary from tree-ring data to AD 903, coupled with models relating runoff to freshwater flow and salinity intrusion. The research characterizes pre-development freshwater flow and salinity conditions in the estuary over the past millennium and compares this with contemporary conditions. The study shows that the past century has seen more variable freshwater flow and greater spring salinity intrusion in the estuary compared to pre-development conditions, highlighting the impact of hydrologic shifts.

Summary: The Cauvery sedimentary basin in India is a result of its separation from East Antarctica in the early Cretaceous. Gravity and magnetic observations reveal a NE-SW trending ridge-depression structure with underplated material and a shear zone under the basin. The interpreted basement geology suggests that the basin's rock is crystalline and not high-grade metamorphic rock.

Summary: Distributed-style volcanism generates clusters of small volcanoes by isolated magma bodies ascending from broad magma sources, helping to infer unobserved geological phenomena. The Tharsis Volcanic Province on Mars covers approximately one-quarter of the planet's surface and contains numerous small volcanoes formed through distributed volcanism.

Summary: The post-collisional Syunik and Vardenis volcanic highlands host over 200 monogenetic volcanoes, with 12 new high-quality 40Ar/39Ar ages indicating active volcanism in the region since at least the late Miocene. The transition from polygenetic to monogenetic volcanism is dated to around 1 Ma, showing spatial and temporal coupling in the formation of new vents. Despite the waning volcanism in the region, a future pulse of activity is possible.

Summary: Research suggests that the large paterae in Arabia Terra were calderas from supereruptions, with extensive ash deposits found throughout the region. The presence of altered volcanic ash deposits, thinning away from the suggested calderas, indicates multiple explosive eruptions over 500 million years. The observations support the hypothesis of supereruptions in Arabia Terra during the late Noachian-early Hesperian period.

Summary: Volcanic flood basalt eruptions are associated with climate disruptions, ocean anoxic events, and mass extinctions. Short-term cooling can occur due to sunlight reflection by H2SO4 aerosols, while long-term warming can occur due to CO2 emissions and increased stratospheric H2O vapor.

Summary: LECZ communities in the southeastern United States are threatened by various factors such as sea level rise and storm surge, highlighting the need for improved communication and collaboration among scientists, stakeholders, and policy makers. Addressing vulnerabilities, public health and safety, economic concerns, and other threats requires a network to assess risks, support adaptive management, and enhance community resilience. Efforts to integrate natural and social sciences are crucial for enhancing the future resilience of these communities.

Summary: This study investigates the hydrogeologic controls and ecohydrologic expression of sandhill wetlands in west-central Florida. The researchers constructed hydrogeologic configurations for different types of sandhill wetlands and proposed two conceptual models to understand their connectivity to the regional aquifer and ecohydrologic expression. These models can improve the classification, assessment, and preservation of sandhill wetlands and similar wetlands with hydrogeologic control.

Summary: Lava tubes are common features on terrestrial planets and hold valuable information about lava flow processes. Exploring lava tubes on the Moon can provide access to geologic environments that have remained unchanged for billions of years and offer protection to astronauts. By using magnetometry, we can determine the size and location of lava tubes on Earth and predict the magnetic anomalies that would be present on lunar lava tubes. This information is crucial for future scientific investigations and human exploration of lava tubes.

Summary: Although the primary application of GPS and GNSS is not reflectometry, the emergence of GNSS interferometric reflectometry technique has enabled monitoring of surface changes such as water level. The authors present a prototype called Raspberry Pi Reflector (RPR) that utilizes low-cost GPS and a Raspberry Pi microcomputer for accurate water level monitoring. The results from RPR are compared to a co-located river gauge, with high accuracy achieved.
