, 2010 Rainfall-induced debris flows involving ash-fall pyroclastic deposits covering steep mountain slopes that surround the Somma-Vesuvius volcano, are natural events representing the main cause of risk for urban settlements located at footslopes.

Computer simulations of pyroclastic flows from dome collapse
, 1998 We present a method of simulating both the avalanche and surge components of pyroclastic flows generated by lava collapsing from a growing Pelean dome.

Tracking a Rangeland Fire With Infrasound Arrays
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract We present the first infrasound analyses of a rangeland fire and demonstrate infrasound's potential in monitoring wildland fires. We recorded a prescribed fire in sagebrush steppe in cool, moist conditions, using eight infrasound arrays of diverse size (3–44 sensors, 10–200 m width) and distance (0–20 km), including four arrays inside the burn

Timing, origin and emplacement dynamics of mass flows offshore of SE Montserrat in the last 110 ka: implications for landslide and tsunami hazards, eruption history, and volcanic island evolution [PDF]
, 2013 Mass flows on volcanic islands generated by volcanic lava dome collapse and by larger volume flank collapse, can be highly dangerous locally and may generate tsunamis that threaten a wider area.

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract The Taruntius crater, situated between Maria Fecunditatis, Crisium, and Tranquillitatis, is characterized by a prominent bright ray system and a floor‐fractured morphology and has long been interpreted as a relatively young Eratosthenian or Copernican crater.

Hydrological Processes, Volume 40, Issue 6, June 2026.Representation (not to scale) of potential high elevation recharge and low elevation return flows within the Guatemala City metropolitan area. ABSTRACT Guatemala City is the most populous urban center in Central America. In this urban center, groundwater extraction within the last 40 years has substantially declined water table levels and accelerated ...

Loess Studies in Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Radon concentration anomalies as possible precursors to pyroclastic flow events of Arenal volcano [PDF]
Geofísica Internacional, 2002 Radon measurements were made at five stations located on Arenal volcano’s cone, Costa Rica, using LR-115 detectors. The radon measuring stations were located on the active cone and one station was located directly over a hotspring. Radon flux anomalies

An Overview of Tsunami Hazards in the Southwest Pacific Ocean
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...
