This week we have some earthquakes, some volcanoes, and another long form update on the Kilauea eruption. Frist we have earthquakes. The following information was provided by the USGS earthquakes site at earthquake.usgs.gov and covers the 11th of September UTC to the 18th of September at 0 UTC.
The same data is also available as a KML file for Google Earth if you want to explore the events.
This week there were 31 events between a magnitude 5 and 6 and a significant earthquake with a magnitude revised down to 6.7 located 28 miles North West of Guam. This earthquake occurred at a depth of 137 km or 85 today at 06:14:46 UTC or 16:14 local time in Guam. Because it was so deep there was no danger of a tsunami. Remember tsunamis happen when the earthquake moves the ocean floor enough to significantly displace the water above it. There was no reported damage.
