As well as August, September was not highlighted by a large event (> M 7). The TOP 3 strongest earthquakes which occurred during this month correspond to a strike-slip earthquake in the Mid-Atlantic Ridge (M 6.9), an interplate EQ in central-north Chile (M 6.8), and another EQ in a different segment of the Mid-Atlantic Ridge (M 6.7). Furthermore, the largest event in Europe occurred on Septembe ...[Read More]
August was not highlighted by a large event (> M7) and the choice for the earthquake of the month was a bit tricky. Four events were available to choose from: An intraplate EQ in the US (M5.1), the largest event in this region since 1916, an M6.6 in the Philippines, a deep earthquake (~620 km) M6.9 in Indonesia, and a doublet earthquake (M6.8 – 6.9) in Indonesia. After some discussion, we ...[Read More]
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]
At 3:34 a.m. (local time) on February 27, 2010, a magnitude Mw 8.8 earthquake occurred in Central Chile and extended over around 500 km along the Maule and Bio Bio regions, a convergent zone between the Nazca and South America plates (Figure 1a). The occurrence of this large earthquake in the context of active subduction zones, as Central Chile, was expected by many Chilean and European res ...[Read More]
