OSU Researchers Study Liquefaction in Nepal
Dr. Ben Mason and Dr. Deepak Rayamahji, geotechnical earthquake engineering researchers from Oregon State University, recently returned from a trip in Nepal, where they studied the liquefaction effects triggered by the M7.8 earthquake and subsequent aftershocks. Their work included documenting collapsed and tilting buildings damaged by liquefaction, and performing in-situ site investigations in an effort to understand the […]
Nearly one fifth of hydropower generation affected
Nepal has a capacity to generate 771MW of power. Out of this, more than 90% is generated from hydropower plants. The current power supply is far less than demand. The country faces hours of load-shedding each day. The April 25 earthquake and series of aftershocks have caused severe damage to several power plants and […]
Some facts on damage to hydropower sector
Some facts on damage to hydropower sector from the recent 7.8 magnitude earthquake: The Ministry of Energy has estimated losses worth $185 million to Nepal’s hydropower sector from the April 25 2015 earthquake. 600,000 households have lost access to electricity. Both existing power projects and those under-construction have suffered damages. The majority of the damages […]
Earthquake a Wake-up Call for Hydropower Developers
Taking lessons from the damages caused by the April 25 earthquake and series of aftershocks, hydropower developers in Nepal are to be more vigilant in undertaking study on geological and earthquake induced landside hazards. As landslides were one of the main causes of damage, the developers have also urged the government to conduct geological […]
Construction of Hydropower Projects still not Resumed
The construction of the hydropower projects located in the quake-affected areas has still not resumed after the April 25 earthquake, reports the Nepalese daily Naya Patrika. The major causes include damage of access roads due to earthquake-induced landslides and workers not returning to the construction sites after the earthquake. The affected projects are Upper Tamakoshi […]
Geotechnical Aspects of the 20th May, 2012 M5.9 Emilia Earthquake, Italy
At 02:03:52 UTC (04:03 local time) of May 20th, 2012 a strong shaking was felt in the Emilia-Romagna Region, in Northern Italy. The magnitude estimates for this event are reported in Table 1. The epicenter was characterized by coordinates 44.89° (latitude) and 11.23° (longitude). The depth of the hypocenter has been estimated as 6.3 km […]
Liquefaction observed in San Carlo di Sant’Agostino
The National Institution of Geologists will be sending teams into the field to carry out investigations on the local effects such as liquefaction, ground deformation and surface faulting in the Province of Ferrara. Figure 1. Figure 2. Figure 3. Figure 4. Figure 5. Figure 6. […]
Liquefaction Effects in San Carlo (Sant’Agostino, Ferrara)
San Carlo is approximately 17 km far from the epicentre. In the following document, an overview of some of the mostly-affected areas in San Carlo is shown. Field measurements, carried out by the Eucentre field teams, aims to quantify the incidence of the liquefaction phenomenon.

Earth Pressure & Slope Failure on Route A16
Traffic disruption due to displaced slopes and rock movements. Traffic on route A16 between the cities of Iquique and Alto Hospicio was interrupted as a result of several slopes displacements and rock falls. This route is of strategic importance for regional economy, and following the earthquake, an 80 m long section descended 40 cm displacing […]
