Kamchatka May 2013

In May 2013 a Swarm, or Series, of Moderate to Strong earthquakes has occurred off the SE coast of Kamchatka Peninsula, Russia.
Each Seismic Network often seems to get a different result on the magnitude and the location of each event and this gives a confusing overview of not only the location of the swarm but the shape and trend of the series as a whole.
Here I have taken the data from RAS, GFZ, EMSC and USGS and mapped out each Network’s data for the same time period period 14/05/2013 10:19 to 21/05/2013 04:59.
Lower down the page are two animations showing the differences in the locations estimated by each Network, at different scales 50km and 100km.
