On Ioto Island (Iwo-jima), 44 phreatic eruptions have been recorded since 1889, when people began to settle there. Four of these eruptions, after the beginning of continuous observation by seismometers in 1976, were accompanied by intense seismic activity and rapid crustal deformation beforehand. Other eruptions on Ioto were without obvious crustal activities. In this paper, we discuss the mech...

Recent advances in seismic data-acquisition technology paired with an increasing interest from the academic passive source seismological community have opened up new scientific targets and imaging possibilities, often referred to as Large-N experiments (large number of instruments). The success of these and other deployments has motivated individual researchers, as well as the larger seismologi...

To enhance our ability to extract palaeobiological and palaeoenvironmental information from ancient thermal spring deposits, we have studied the processes responsible for the development and preservation of stromatolites in modern subaerial thermal spring systems in Yellowstone National Park (USA). We investigated specimens collected from silica-depositing thermal springs along the thermal grad...

Acromioclavicular joint (ACJ) cysts are an uncommon and unusual sequela associated with shoulder pathophysiology. The majority of literature on ACJ cysts consists of individual case reports with no definitive literature review currently available. In addition to a comprehensive literature review, four clinical cases are presented in this report. First described by Craig (1984), a total of 41 ca...

South Africa is the most technologically advanced nation in Africa. However, country plagued with constant load shedding. The receives about 2500 sunshine hours annually, daily average irradiation levels of 4.5–6.5 kWh/m2. Despite these potentials, use electricity for domestic water heating still prevalent country. mass rollout solar (SWH) technologies low-cost housing sector across were met ma...

Coronal mass ejections (CMEs) and coronal jets are two types of common solar eruptive phenomena, which often independently happen at different spatial scales. In this work, we present a stereoscopic observation large-scale CME flux rope arising from an unwinding blowout jet in multipolar complex magnetic system. Based on multi-band observational analysis, find that whole event starts with small...

Geothermal surface manifestations (GSMs) are direct clues towards hydrothermal activities of a geothermal system in the subsurface and significant indications for resource exploration. It is essential to recognize various GSMs potential energy However, there lack work fulfill this task using deep learning (DL), which has achieved unprecedented successes computer vision image interpretation. Thi...
