A new article by Dr Heidarzadeh See the full article here (free pdf): https://doi.org/10.1080/21664250.2022.2122293 Abstract (based on https://doi.org/10.1080/21664250.2022.2122293): The September 2018 Palu (Sulawesi, Indonesia) tsunami has been a heavily debated event because multiple source models of three different types have been proposed for this tsunami: (i) The Mw 7.5 earthquake, (ii) landslides, and (iii) dual earthquake […]

Lessons from the 2019 Toddbrook dam incident would save UK’s aged infrastructure

Dr Mohammad Heidarzadeh (PhD, CEng, MICE, C.WEM, MCIWEM) Senior Lecturer of Civil Engineering at the University of Bath (mhk58@bath.ac.uk) A new study shows that the 2019 Toddbrook dam incident (Figure 1), where the dam was on the brink of collapse, was the outcome of (1) poor maintenance, (2) inadequate design, and (3) torrential rainfall leading […]

Numerical modeling (simulations) of the trans Pacific tsunami from the 1 April 2014 Iquique (Chile) M 8.2 earthquake

We analyzed the trans Pacific tsunami that was generated in the Pacific Ocean following the 1 April 2014 Iquique earthquake offshore Chile. The Iquique (Chile) earthquake moment magnitude was 8.2 and occurred at the depth of around 25 km. The earthquake killed at least 7 and left around 200 injured.   The resulting tsunami reached […]

Excitation of basin wide modes (free oscillations) of the Pacific Ocean by the 11 March 2011 Tohoku (Japan) tsunami

The 11 March 2011 Tohoku (Japan) tsunami was a unique event in several ways. The tsunami caused 4-5 days of surface oscillations inside the Pacific Ocean. This was an indicative of long-mode excitation of the Pacific Basin. To further examine which modes of the Pacific Ocean were excited by the 2011 Tohoku (Japan) tsunami, Heidarzadeh […]
