A large submarine landslide contributed to the September 2018 Palu (Sulawesi, Indonesia) tsunami
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 […]
Tsunami generated by the January 2022 Tonga volcano eruption was 90 m high
By: Dr Mohammad Heidarzadeh Associate Professor of Civil Engineering at the University of Bath (England) Secretary General of the International Tsunami Commission. Email: mhk58@bath.ac.uk A new study shows that the deadly and global-reaching tsunami generated by the Hunga Tonga–Hunga Haʻapai volcano in January 2022 was as high as 90 m (see Figure 1). The tsunami […]
Empirical Green’s functions for tsunamis
For first time, we developed empirical Green’s functions for tsunamis. The details are shown in the figure. There were two tsunamis in the Solomon Islands region in July 2015 (Mw7.0) and in February 2013 (Mw8.0; known as the Santa Cruz tsunami). The sources of the two tsunamis are very close to each other (see asterisks in […]
Earthquake and tsunami hazards in the Solomon Islands, Santa Cruz Island
A magnitude 7.0 normal-fault earthquake occurred in the Solomon Islands on 18 JUly 2015. This earthquake generated a small tsunami. The epicenter was ~40 km to the north of the 6 February 2013 Santa Cruz Mw 8.0 thrust earthquake. We studied these two events and realized that the recent normal-fault earthquake was possibly triggered by […]
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 […]
Seismic performance of structures and buildings during the 26 December 2003 Bam earthquake, Iran
A large earthquake with magnitude M 6.3 occurred in City of Bam in Kerman province, southeast of Iran on 26 December 2003. The earthquake caused a death toll of ~35000. Shortly after the earthquake, we visited the city to assess the performance of the buildings and structures. Most of the houses were adobe houses or […]
