Summary: During the 2009 Padang earthquake in Sumatra, rapid-moving landslides occurred in an area of 64 km(2) at 159 locations. These landslides were induced by pumice fall deposits thicker than 350 cm, with sliding surfaces at the base of the pumice fall deposits indicating mechanical instability. The geological history of pumice fall, weathering, and undercutting is common in volcanic areas, providing the opportunity to predict areas susceptible to earthquake-induced catastrophic debris avalanches.

Summary: Unconfined pyroclastic density currents (PDCs) are highly dangerous volcanic hazards that can cause significant impacts on inhabited areas. Previous studies have only described a limited number of specific cases of unconfined PDCs. In this study, a comparative analysis is conducted to review the different types of unconfined PDCs, their characteristics, dynamics, and impacts, emphasizing the importance of accounting for these phenomena in emergency management and planning at active volcanoes.

Summary: Volcanic tephra fall deposits are commonly characterized by thickness and grainsize. This study analyzes the grainsize data of 56 deposits representing different eruption intensities and magnitudes. It found that bimodal fall deposits are formed by eruptions with large amounts of fine particles, and all tephra-fall deposits show characteristic patterns of grainsize decay with distance from source that can be related to eruption plume height and intensity. Grainsize is important for interpreting tephra-fall deposit records.

Summary: The study suggests the presence of volcanic deposits on Mars related to explosive volcanic eruptions potentially formed due to interactions with water or ice, serving as a record of past water on the planet. By analyzing Mars analog tephra samples using orbital spectroscopy, researchers aim to determine eruption styles and past water presence during volcanic events. The research demonstrates that combining visible/near-infrared and thermal infrared data can help detect glass abundances in volcanic deposits and infer tephra types, offering insights into Martian volcanic and volatile histories with potential applications for planetary exploration.

Summary: By analyzing video data from a UAV, we were able to determine the movements of the volcano dome surface and estimate the initial eruption velocities and mass eruption rates. We found that the eruptive strength is correlated with deformation magnitude, and this correlation is supported by a numerical model. Our research demonstrates the usefulness of photogrammetric methods in quantitatively constraining and monitoring volcanic activity.

Summary: On January 15, 2022, a violent eruption of the Tonga volcano resulted in explosion-like atmospheric shock waves and subsequent tsunami waves along the Pacific coast. This study investigates the leading tsunami wave linked to the atmospheric pressure disturbance and examines whether the tsunamis along the coast of Japan are caused by Proudman resonance. The research shows that the pressure disturbance from the volcanic eruption spread rapidly over the Pacific Ocean, but only resulted in significant tsunamis along the coast of Japan due to nearshore amplification.

Summary: This study demonstrates the occurrence of paleo-wildfire events during the Campanian age of the Late Cretaceous in deposits from King George Island, Antarctic Peninsula. Through the analysis of charcoal samples collected during expeditions, morphoanatomical structures with potential taxonomic affinity with Podocarpaceae were identified. The analysis also reveals that southern paleofloras experienced more frequent paleo-wildfires than previously thought, suggesting the significant impact of fire and active volcanism on the ecological niches of austral floras.

Summary: The paper reviews recent studies on sedimentary archives of coastal inundation events in Morocco. The authors identified 20 sites with traces of coastal inundation deposits along the Atlantic coast, while the Mediterranean side remains understudied. A major issue is the lack of chronological data for most of these deposits, which hinders the determination of the return period of these events. Understanding the past occurrences can help in preventing similar natural hazards.

Summary: Granular flows moving down mountainsides and entering water bodies create granular jets and particle-driven gravity currents, with hydrodynamic forces mainly slowing down and reducing the spread of granular masses. The experimental study demonstrates that the temporal evolution of these flows can be described by ballistic motion theory and scaling laws, highlighting the complexity of dynamics and deposits when granular masses encounter water bodies.

Summary: The geomorphological survey conducted near the Minoan town of Malia in Crete revealed evidence of a tsunami reaching the Palatial center as a result of the Bronze Age Santorini eruption, inundating up to 400 meters inland. The sediment cores confirmed a unique erosional event during the Late Minoan period, followed by a high energy sand unit containing marine fauna. This opens up new research opportunities regarding the impact and consequences of the Bronze Age Santorini tsunami on the Minoan civilization.

Summary: River deltas are significantly impacted by demographic growth and land use intensification, leading to rapid migration of coastal areas and threats to urban settlements, coastal farming, and ecosystems. Studying the geomorphological evolution of deltas can be enhanced through the use of overlapping maps and aerial photographs, along with satellite images, to track changes in fluvial and coastal landforms. The evolution of river channels and coastlines in the Aceh River delta over the past 130 years reveals a progressive decrease in sediment supply, resulting in lengthening and narrowing of river channels, landward migration of the shoreline, and narrowing of beach ridges. The 2004 Indian Ocean tsunami caused an instantaneous retreat of the coastline, accelerating the overall trend of retreat. Beach ridges located up-drift of rivers and tidal channel mouths are particularly vulnerable to long-term landward retreat and tsunamigenic erosion.

Summary: Despite significant scientific advances in recent years, the pre-colonial history of Tonga and West Polynesia before the 16th century still has major gaps. In the 14th century, the powerful Tu'i Tonga kingdom united the islands under central authority, but by the mid-15th century, they faced deep crisis possibly linked to a large tsunami event.

Summary: Indonesia is prone to earthquakes, volcanic activities, and tsunamis. The study aimed to investigate marine-origin sediments along the Alas Strait of Indonesia to find evidence and determine their ages. Coral and seashell samples from the western coast of Sumbawa yielded possible tsunami deposits dating back to the 4th, 9th, and 17th centuries, indicating past large earthquakes triggered these tsunamis rather than volcanic eruptions.
