Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another. The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (M w) that can exceed 9.0.
The country has been shaken by more than 800 small earthquakes today alone, ... The earth is at its most restless in Iceland right now. ... most likely location is at the magma tunnel according to ...
Megathrust earthquakes are the most powerful earthquakes known to occur, and can exceed magnitude 9.0, which releases 1,000 times more energy than magnitude 7.0 and 1 million times more energy than a magnitude 5.0. [18] [19] [20] They occur when enough energy (stress) has accumulated in the "locked" zone of the fault to cause a rupture. The ...

Modern earthquake location still requires a minimum of three seismometers. Most likely, there are many, forming a seismic array. The emphasis is on precision since much can be learned about the fault mechanics and seismic hazard , if the locations can be determined to be within a kilometer or two, for small earthquakes.
Iceland earthquake locations revealed as volcano eruption alert issued 04:00 , Lydia Patrick Iceland is experiencing a seismic swarm as 1,485 earthquakes have hit the country in just 48 hours ...
The main scientific goal of the centre is the definitive compilation of earthquake information and the readings on which they are based. Collection of reports of earthquake effects is also an important part of its operation and the Centre recomputes the location and occurrence time of earthquakes worldwide, making use of all available information.
