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.
