Forensic Seismology: The Beirut Explosion

Forensic Seismology: The Beirut Explosion

On August 4, 2020, the coast of Beirut, the capital of Lebanon, was rocked by an explosion caused by the blowing up of 2750 metric tons of ammonium nitrate, a chemical used in fertilizers (Figure 1).

Footage of the explosion has circulated widely: a large fire near the port’s warehouses and an in ...[Read More]

From light to waveform: how fiber-optic cables can be repurposed as seismic arrays

From light to waveform: how fiber-optic cables can be repurposed as seismic arrays

What is Distributed Acoustic Sensing (DAS) and why is it exciting? Any observational seismologist would agree that our understanding of subsurface structure and dynamics is in great part limited by our ability to acquire data at the right locations, with the necessary spatial and temporal resolution. However, although our ultimate objective would be to cover the Earth with high-quality, broadband ...[Read More]

Earthquake of the month: Simeonof – Alaska M 7.8

Earthquake of the month: Simeonof – Alaska M 7.8

On July 22nd, Alaska was the scene of last month’s largest earthquake, a Mw 7.8 earthquake that hit the Aleutian Islands, offshore the Alaska Peninsula. The hypocenter location, tectonic setting and focal mechanism suggest a megathrust earthquake. The hypocenter of the so called Simeonof earthquake is located at the western edge of the historical 1938 earthquake (M8.3) slip zone, near the Shumagin ...[Read More]
