Geomorphic environments play a crucial role in influencing the preservation and characteristics of tsunami deposits. This paper introduces a global database of tsunami deposits, encompassing information on deposit locations, thematic data such as geomorphic environments and proxies and bibliographic details. Additionally, the database features maps...

Tsunami deposits provide evidence of historical and prehistorical events. However, their preservation in tropical regions is generally poor. The reasons behind this poor preservation are often linked to a number of environmental and anthropogenic factors. This study is focused on analyzing the environmental factors that impact the preservation and...Tsunami deposits provide evidence of historical and prehistorical events.

Globally, the largest tsunamigenic earthquakes have occurred along subduction zones. Devastating events exceeding magnitude 9, such as those in Chile, Sumatra, and Japan, struck in regions lacking instrumental records of similar events. Despite the absence of such events along the 1000-kilometer-long Mexican subduction zone, historical and geologic...

The database contains information on the global distribution of historical and prehistorical tsunami deposits, categorized into two groups based on their location: the Tropical Zone and other climatic zones. It includes geographical coordinates, bibliographic references, year of publication, location by region and country, geomorphic environments w...

Globally, the largest tsunamigenic earthquakes have occurred along subduction zones. The Mw>9 devasting events in Chile, Sumatra, and Japan struck in areas where no instrumental records reported similar events. The one-thousand kilometer-long Mexican subduction zone (MSZ), where the Rivera-Cocos plates subduct under the North American plate, has no...

Diatoms are an important proxy in tsunami and storm research studies to determine potential sediment source and changes in environments pre- and post-event. However, the use of this proxy has proven challenging when studying extreme wave paleo events in sediments from the humid tropics because of the scarcity of diatoms in sand beds, and in clay or silt beds above and below....

The massive explosion by the January 15, 2022 Hunga Tonga-Hunga Ha'apai volcano in Tonga triggered a trans-oceanic tsunami generated by coupled ocean and atmospheric shock waves during the explosion. The tsunami reached first the coast of Tonga, and later many coasts around the world....

Landslide detection and susceptibility mapping are crucial in risk management and urban planning. Constant advance in digital elevation models accuracy and availability, the prospect of automatic landslide detection, together with variable processing techniques, stress the need to assess the effect of differences in input data on the landslide....

Uplift is the predominant factor controlling fluvial systems in tectonically deforming regions. Mountains along subduction zones force incision, aggradation, or sinuosity modifications, showing differential uplift and variations in erosion rates, in river incision, and in channel gradient produced by ongoing tectonic deformation....

The 23 June 2020 Mw 7.4 La Crucecita, Oaxaca, Mexico Earthquake and Tsunami: A Rapid Response Field Survey during COVID‐19 Crisis
The 23 June 2020 La Crucecita earthquake occurred at 10:29 hr on the coast of Oaxaca in an Mw 7.4 megathrust event at 22.6 km depth and triggered a tsunami recorded at tide gauge stations and a Deep-ocean Assessment and Reporting of Tsunamis off the coast of Mexico. Immediately after the earthquake, a rapid response effort was coordinated by member...

Globally, instrumentally based assessments of tsunamigenic potential of subduction zones have underestimated the magnitude and frequency of great events because of their short time record. Historical and sediment records of large earthquakes and tsunamis have expanded the temporal data and estimated size of these events. Instrumental records sugges...
