A massive magnitude 7.5 quake has rocked South Alaska. The reasonably shallow quake 

struck early this morning and a swarm of large aftershocks have followed. There are no reports 

of damage. According to the Anchorage Daily News, the magnitude 7.5 earthquake hit off the 

Alaska Peninsula coast Monday afternoon and triggered a tsunami warning for communities 

along hundreds of miles of coastline.

The warning was cancelled after about three hours, but communities had evacuated 

to higher ground during the chaos. Monday’s earthquake was an aftershock of the 

magnitude 7.8 quake that struck the same area in July, said State Seismologist Michael West. The earthquake 

triggered more than two dozen of its own aftershocks shortly after, ranging from 3.5 to 5.9 magnitude. West said additional aftershocks will continue in the area for days after.

Today's major quake (mag 6 or higher) is only the 5th of this month but is by far the biggest of 

this month. 2020 has so far recorded 103 major quakes, (mag 6 or higher) with the magnitude 

7.8 quake that struck the same Alaskan area in July being the biggest of the year so far.
