... and even in some scientific articles about landslides being caused by ‘water lubrication’. Some lessons, it seems, are never learnt. Reading the whole paper, it becomes apparent how advanced the understanding of landslide mechanisms was 70 years ago. It also appears to be the case that since 1950 lessons...

... the Sumatran fault in Sumatra, western Indonesia, since 1921 by using the MJHD method. We added M ≥6.0 earthquakes that took place during 1921–2012 in this relocation. By combining better quality recent data with poorer old ones helped to constrain the locations of pre‐1950 earthquakes. We found that six M...

The dataset has been processed using the horizontal-to-vertical spectral ratio ( HVNSR ) technique and interpreted in terms of local geology, which is characterized by the presence of alluvial sediments of two riverbeds masked by urbanization since the seventeenth century. HVNSRs show significant variations...
