On 24 September, 2013, a magnitude 7.7 earthquake occurred in Balochistan, Pakistan. The quake caused intense ground motions and had dramatic consequences – hundreds of people died, and more than 100,000 lost their homes. A secondary effect which caught much attention in the international media was the birth of an island off the Pakistani coast – Zalzala Jazeera or Earthquake Island. Another effect which went almost completely unnoticed was a small tsunami in the Arabian Sea. The tsunami reached wave heights of around 1 m at the Omani coast. In a paper which was recently published in Geology, my colleagues and me document the tsunami effects in Oman. We conclude on a submarine slide off Pakistan as the likely trigger mechanism.

Palaeotsunami in Lake Geneva2012-10-29 | in Paper
Let’s see, this is my 1st post here, thanks again for the invitation. Today, an interesting story circulated through mass and science media. The article by Kremer et al. published yesterday in Nature Geoscience presents geophysical and sedimentological evidence of potential tsunamis in the rather exotic environment of Lake Geneva. This phenomenon is not new at all and has been investigated by others before, but I pretty much share the authors conclusion, that the hazard of tsunami-like events in continental lakes deserves higher attention in the future.
