Amateur radio operators help fill earthquake donut holes

If you’ve ever seen tall antennas rising from everyday residences in your community and wondered what they are for, it could be that those homes belong to ham radio enthusiasts who enjoy communicating with each other over the airwaves. In addition to having fun with their radios and finding camaraderie, many ham radio operators are also prepared to help neighbors and authorities communicate during disasters. One such group of radio enthusiasts is poised now to serve yet another important role: They will be contributing to a more robust delivery mechanism for critical seismic intensity reports after major earthquakes through the U.S. Geological Survey’s (USGS) Did You Feel It? (DYFI) system.

Why study geysers?

Scientific research for more than two centuries has improved our understanding of Earth’s geysers. This knowledge provides insights into volcanic processes, the origin and environmental limits of life on Earth and potentially Mars, and on geysers on icy outer solar system satellites. Continued scientific research will help us understand and protect these natural wonders that attract millions of tourists annually.

Planetary dunes tell of otherworldly winds

Dune fields are common on beaches and in deserts—think of the imposing sand hills and sinuous ripples of the Sahara in Africa or the Karakum in Central Asia, for example—as well as underwater on the beds of rivers, lakes, and oceans. The varied shapes, sizes, and orientations of both modern dunes and those preserved in the geologic record tell of the conditions under which they formed, particularly the strengths and patterns of winds and ocean currents. This information offers us valuable windows into environments and climates at different places and at different times in Earth’s history.

Planting seeds for thriving data management

The volumes and varieties of data coming from all types of scientific instrumentation around the globe and beyond are rapidly growing. To reuse and capitalize on these data effectively, scientists must be able to share and access them efficiently, which requires the data to be well managed. Many scientists intuit that research data management (RDM) done well does not mean using dusty USB drives or aging laptops for storage. Yet the path to strong data management is not always clear. How is RDM done? Who does it? For science to advance, we need to bolster cyberinfrastructure and human capacity to ensure that the data being collected are reusable by both humans and machines.

How to accelerate advances in ecological forecasting

Ecological forecasting offers critical insights for managing natural resources and safeguarding public well-being. Despite growing demand for these forecasts, progress is hindered by fragmented systems, redundant workflows, and limited interoperability. Drawing lessons from weather forecasting and recent successes like the NEON Ecological Forecasting Challenge, shared cyberinfrastructure is important for advancing ecological prediction. By adopting common standards, open-source tools, and scalable architectures, and fostering transdisciplinary collaboration, the ecological forecasting community can overcome technical and institutional barriers. Such investments could accelerate scientific understanding, improve forecast reliability, and empower decisionmakers to anticipate environmental change and respond effectively.

A hybrid approach for revealing headwater hydrology

Coordinated work to compile existing data and apply models pairing physical understanding with machine learning could substantially improve streamflow predictions for little-known headwater basins.

Team investigates activity at Mt. Semeru, Java, volcano

In February 1994 a large eruption continued a pattern of activity that Mt. Semeru volcano—the highest mountain in Java, Indonesia—has exhibited since 1967. Mt. Semeru lies south of the Tengger Caldera, which encloses the volcano Mt. Bromo. Together, they form one of the largest volcanic complexes in the province of East Java. Although Mt. Semeru is one of the most continuously active volcanos in Indonesia, it has been the subject of few scientific investigations. Observations of the volcano's activity are made from a distance and compiled in monthly and annual reports by the Volcanological Survey of Indonesia (VSI), but the most recent detailed map of the summit region was published in 1938 in the Atlas of the Dutch Colonies.

Notes on the relation between the moisture‐equivalent and the specific retention of water‐bearing materials

The moisture‐equivalent and specific retention have been widely used as quasi‐physical constants to measure the power of a water‐bearing material or a soil to retain water against gravitative force. Comparatively little has been demonstrated, however, as to the relation of one to the other. This paper is a preliminary statement of the apparent relation between these two measures of retentive power and is based on a study of alluvial materials made in connection with an investigation by the United States Geological Survey into the ground‐water resources of the Mokelumne Area, central California.

Deep‐seated solution in the Meade basin and vicinity, Kansas and Oklahoma

During the closing years of the 19th century, Haworth [see 1 and 2 of “References” at end of paper] and Johnson [3] noted the abundant depressions resembling sink‐holes in the Southern High Plains, especially in Meade and Clark counties, Kansas, and Beaver County, Oklahoma. Johnson was of the opinion that all the depressions and basins in this region were due to solution, whereas Haworth [1] believed the Meade artesian basin to be structural, although he held to a solutional origin for the Ashland and Englewood basins, which are a few miles to the east. ©1942.

One hundred years of volcano monitoring in Hawaii

In 2012 the Hawaiian Volcano Observatory (HVO), the oldest of five volcano observatories in the United States, is commemorating the 100th anniversary of its founding. HVO's location, on the rim of Kilauea volcano (Figure 1)—one of the most active volcanoes on Earth—has provided an unprecedented opportunity over the past century to study processes associated with active volcanism and develop methods for hazards assessment and mitigation. The scientifically and societally important results that have come from 100 years of HVO's existence are the realization of one man's vision of the best way to protect humanity from natural disasters. That vision was a response to an unusually destructive decade that began the twentieth century, a decade that saw almost 200,000 people killed by the effects of earthquakes and volcanic eruptions.
