There are potentially other terms that can be added later that are not included in the classification. A horde of escaped crayfish (koura) was a side effect of Monday's massive 7.8 magnitude shake, according to Ward resident Kerry Snell. The area affected by landslides is relatively remote with few people living there, and so only a few homes were impacted by landslides; there were no recorded deaths due to landslides. Our landslide and paleoseismology teams quickly took to the skies to spot landslides in the Kaikouras and Southern Alps. A unique number for each digitiser’s working copy of the database. The largest landslides triggered by the earthquake are located either on or adjacent to faults that ruptured to the ground surface. Imagery date: 25 November 2016; GeoEye (GE) 2 m resolution. The large landslides in the centre left of the photo did not reach the foot of the slope during the initial failure and the debris is a hazard that will remobilize in an aftershock or rainstorm and will present an ongoing risk to road and rail users if mitigation measures are not implemented. GNS Science miscellaneous series 101. Post-earthquake digital elevation models derived from airborne LiDAR. Karmini reported from Jakarta, Indonesia. If there is a second material type involved which appears to have had a significant influence on the failure or runout mechanics, then can include a second material type. Kaikoura earthquake landslides: the picture slowly emerges As parts of New Zealand continue to reel under the combined effect of the ongoing aftershocks and the effects of very heavy rainfall, the effects and extent of the Kaikoura earthquake landslides are slowly emerging. (AP Photo/Yusuf Wahil). The majority of landslides occurred predominantly in two geologically and geotechnically distinct materials, namely: weak to moderately strong (5-50 MPa) Neogene sedimentary rocks (limestones, sandstones and siltstones), and moderately strong to very strong (20-100 MPa) Triassic to Cretaceous Torlesse “basement” rocks (sandstones and argillite). Officials, however, were cautioning that weather conditions could hamper rescue operations. These linear features are attributed with the type of surface deformation (from the ‘Type’ dropdown list). p. 443-450 (paper 053) IN: Williams, A.L. The now-named Kaikoura Earthquake triggered up to 100,000 landslides in Northern Canterbury and southern Marlborough. imagery etc.) The active fault ruptures caused by the earthquake are shown as black lines. The national LINZ 8 m resolution digital elevation model (DEM) covers the entire area affected by landslides and is also being used for the mapping. In addition, a 1 m resolution DEM generated from pre-earthquake LiDAR covers a small coastal strip, but is still useful where applicable. used to digitize the landslide, and confidence in the mapping. Landslide crown: A point at the top of the landslide crown/headscarp (highest point). He said his team was working to save dozens of people trapped in eight buildings, including in the governor's office, a hospital and a hotel. Kaikoura Earthquake. The significant geotechnical impacts of the event included surface fault rupture and landslides, and observations of site effects, liquefaction, and social impacts were also important. Landslide dams: Hapuku is just one of 200 landslide dams created when the November 14 earthquake dislodged massive slips into river valleys. On Thursday, a magnitude 5.9 undersea quake hit the same region, damaging several homes but causing no apparent casualties. One of the main uses of this data will be to assess how slopes performed in particular rock and soil (material) types during the earthquake. First-time failure, reactivated, retrogressed. These photographs (many thousands) have been captured by the landslide reconnaissance team and others post-earthquake, mainly from helicopters. There were reports of many people trapped in the rubble of collapsed homes and buildings. Its chairwoman urged people in coastal areas to move to higher ground as a precaution. From the Elixis Group Ltd., Athens, Greece: J Manousakis. relationships with topography, geology, fault structures, shaking). See below a selection of photos. The energy released would be four times that of the Kaikoura earthquake, and 700 times that of the 2011 Christchurch earthquake. Uncoupled (i.e. Use ‘undifferentiated’ if you cannot tell which style of movement. Work areas that cannot be mapped (e.g. ; Hammond, K.A.T. A woman died in a log house that was damaged at Mount Lyford. This landslide is at -42.237, 173.664 if you want to take a look on Google Earth. Sirajuddin, who goes by one name, said although the inland earthquake did not have the potential to cause a tsunami, people along coastal areas ran to higher ground in fear one might occur. After several hours, an excavator came to help and the rescuers eventually retrieved four survivors and three bodies. West Sulawesi Administration Secretary Muhammad Idris told TVOne that the governor's office building was among those that collapsed in Mamuju, the provincial capital, and many people there remained trapped. Landslides caused major disruption with all road and rail links with Kaikoura being severed. Early reports said her cause of death was a heart attack, but an autopsy later indicated it was a head injury suffered durin… Orcas (Dolphins) Can and Do Kill Killer whale (orca) kills trainer at SeaWorld amusement park in Orlando, Florida A female trainer was killed by a 6.5 ton killer whale (orca) at SeaWorld's Shamu Stadium in Orlando, Florida, police and local media reported. Initial mapping method (i.e. These factors are then combined with topographic slope angle and geologic information to generate event-based statistical or deterministic models used to explain the distribution of landslide frequency and area or volume. Given the sparsely populated area affected by landslides, only a few homes were impacted and there were no recorded deaths due to landslides. The most intense landslide damage was concentrated in 3500 km2 around the areas of fault rupture. The authors also thank the paper reviewers for their comments. evidence of incipient failures, such as scarps, anti-scarps, or cracks that occur outside of the landslide polygons), can be mapped using a Surface Deformation feature class. To ensure a consistent methodology for capturing landslide information, several feature classes in an ArcGIS geodatabase have been set up, with fields containing drop down (restricted) lists for capturing the key landslide information. NZGS 2021 | These have moderate positional accuracy and in some mountainous areas the images have been orthorectified using a low-resolution digital surface model. Among the dead in Majene were three people killed when their homes were flattened by the quake while they were sleeping, said Sirajuddin, the district’s disaster agency chief. Indicates whether landslide appears to be a first-time failure or a reactivation of a previous movement. GeoNet, the geohazards monitoring programme run by GNS Science and funded by EQC, responds to major landslide events in New Zealand using a set of well-established criteria (Dellow 2001, McSaveney et al. Rock, clay, mud, coarse clastic (e.g. Low level aerial oblique photographs are also being used to help define the landslides. Landslides caused major disruption with all road and rail links to Kaikoura being severed. occlusions, blockages, buffered), and method of mapping and source of the data, along with the person who digitised and attributed the landslide (Table 1). A man was crushed and died when the historic Elms Farm homestead near Kaikōura collapsed. Along the Kaikoura coastline, earthquake conversation keeps turning to the native crayfish for which the coast is named. More than 4,000 people died, many of the victims buried when whole neighborhoods were swallowed in the falling ground. The 2016 M7.8 Kaikoura Earthquake severely affected the South Island of New Zealand. The 7.8 magnitude quake lifted the seabed by 0.5 to 2 meters (2 to 7 feet) along a 20-kilometer stretch of the Kaikoura coast. Indonesia, a vast archipelago of 260 million people, is frequently struck by earthquakes, volcanic eruptions and tsunamis because of its location on the “Ring of Fire,” an arc of volcanoes and fault lines in the Pacific Basin. , S., Picarelli, L., 2014: the landslide, and 700 times that of mapped...
