This project, developed by the Department of Geophysics of UdeC, currently monitors the coastal zones of Hualpen and San Pedro de la Paz by means of a wave sweep every 33 seconds, in order to detect sea level variations, which will contribute to the decision making made by the SHOA when facing a tsunamigenic
Pakistan's coastal areas particularly the Makran Subduction Zone (MSZ) had major tsunami threats that under went a destructive tsunamigenic
earthquake in 1945 which caused over 4,000 casualties.
As introduced above, the larger downstream zone (Site 1) of the Rogun dam construction site was studied to assess the probability of occurrence of a massive failure event similar to the one observed downstream from Baipaza HPP in 2002; the smaller upstream Site 2 that can be seen on some maps (Figures 6 and 7) was investigated due to the possibility of a potentially tsunamigenic
impact of an existing mass movement on the lake.
From all information reported, we proposed a tsunamigenic
model of the main shock considering a set of three faults as the main seismogenic source of the earthquake (Yelles-Chaouche et al., 2009b).
earthquakes have epicentres close to the shore, the time between a seismic event and the issue of a warning may be limited to just a few minutes.

Active subduction zones are some of the most likely plate interfaces to generate quakes of catastrophic magnitude and also pose the greatest risk of triggering tsunamigenic
tectonic events," according to Dr.

events associated with the extreme tide level changes in the Colombian pacific coast.
The model also generated acoustic data; an interesting revelation of the simulation was that tsunamigenic
surface-breaking ruptures, like the 2011 earthquake, produce higher amplitude ocean acoustic waves than those that do not.
We are sure that these blocks were not moved by hurricanes that affected the coastlines in the past years, therefore, we expect that they are of tsunamigenic
origin," said Prof.
