Flooding and landslide kill nineteen in the Attica Region of Greece.

Sciency Thoughts | 18 November, 2017
Nineteen people have died and a further three are missing following a series of flash floods and landslides in the Attica Region of Greece since Tuesday 14 November 2017. Many houses and businesses have been inundated in the towns of Mandra, Nea Peramos and Megara, and part of the Athens-Corinth highway has been washed away near Athens.

Magnitude 5.4 Earthquake in North Gyeongsang Province, South Korea.

Sciency Thoughts | 18 November, 2017
The United States Geological Survey reported a Magnitude 5.4 Earthquake at a depth of 10.0 km about 10 km northwest of the city of Pohang in North Gyeongsang Province, South Korea, slightly before 2.30 pm, local time (slightly before 5.30 am GMT) on Wednesday 15 November 2017. The quake caused extensive damage to buildings in and around Pohang, with over a thousand buildings destroyed or damaged and more than 1500 people made homeless and 57 reported injuries, with ten people hospitalised and two described as being in critical conditions. People have reported feeling the event across South Korea, and it is likely that it was also felt in North Korea. The event was followed by at least 45 aftershocks.

Walking on Rivers — Dry Riverbeds as Public Parks?

The Nature of Cities | 18 November, 2017
In most arid regions of the world cities are growing and rivers are running dry. While rapid urbanisation has left little room for creating new public open spaces, could urban riverbeds that remain dry for an extended period of time provide potentials for new types of public parks? Dryland settlements were historically established along flowing ... Continue reading Walking on Rivers -- Dry Riverbeds as Public Parks? â†'

Highlights: Lobe Geometries Shaped by Channels

JSR Paper Clips | 17 November, 2017
Channels and lobes, lobes and channels--the processes, dynamics, and geological record of deep-water fan systems are shaped by their interactions. In this paper, Hamilton et al. explore the relationship between the hydraulics of the channel feeding deep-water lobes in steep fan systems and the geometric properties of thickness, width, and length of the resultant terminal submarine fan lobes. Building on a series of laboratory tank experiments and high-resolution seismic data from the Quaternary east Corsica Trough, Golo Basin, the data show that distributary channel hydraulics can aid in describing the processes that set the maximum thickness of lobe elements. They further suggest that the maximum lobe element thickness can be estimated using a hydraulic jump equation if flow in the distributary channel is supercritical. The results illustrate how analytical morphodynamics, when tied to processes, can provide unique perspectives on the nature and scales of heterogeneity on analogous systems

Detecting landslide precursors from space

The Landslide Blog | 17 November, 2017
A holy grail of landslide studies is the ability to anticipate future behaviour by reliably detecting precursors.  This is a highly fraught activity at any level, with the complexity of landslide behaviour rendering the interpretation of patterns of movement challenging.  However, in situ detailed monitoring has yielded some interesting results over the years, and efforts continue.  Meanwhile, developments in satellite technologies mean that detecting deformation from space is becoming increasingly possible.  In particular, the InSAR technique, which uses techniques to compare repeated radar images, is very promising. The latest generation of ESA radar satellites, Sentinel 1A and 1B provide high quality imagery every six days in some cases.  Thus, intuitively it feels that there is the potential to use these techniques to detect precursory landslide activity that might indicate that a collapse is likely, providing mechanisms to anticipate failure events and thus make communities safer.

Deming Slide Complex Notes

In preparation for a field trip to see and view a few deep-seated bedrock landslides I pulled up a lidar image of one of the roads we area heading up to view another slide. The route takes to an area that appears to have some slide features as well as a rather fractured looking slope.

Terrible Lizards - a bestiary

Believe it or not, I'm not familiar at all with Dungeons & Dragons. Of course I know what it is, and that there's a Dungeon Master overseeing things and lots of high fantasy and dice and such, but not much more than that. It's just not something that I've really been exposed to (if you'll forgive the use of a word that makes it sound slightly unseemly). So, I was intrigued when we were contacted by Ralph Stickley, who's produced a bestiary entitled Terrible Lizards, with the laudable aim of bringing up-to-date dinosaurs to the game.

Eruption on Mount Dempo, Sumatra.

Sciency Thoughts | 16 November, 2017
The Badan Nasional Penangulanggan Bencana (Indonesia's Disaster Mitigation Agency)has reported an eruption on Mount Dempo, a 3173 m stratovolcano (cone shaped volcano made up of layers of ash and lava) in South Sumatra, on Thursday 9 November 2017. The eruption began slightly after 4.50 pm local time, and produced a dense ash plume that rose about a kilometre above the summit of the volcano and drifted to the south.
