Tracking Earthquakes and Volcanoes
Magnitude 5.4
Location Nepal-India border region
Date Monday, April 4, 2011
Time 11:31:40 UTC
Depth (where the focus occurred) 12.50 km (7.77 mi)
Determine the basic type of tectonic plate boundary it occur at (i.e. oceanic-to-oceanic, continental-to-continental, oceanic-to-continental, transform, divergent, or intraplate)
Continental to continental
Explain WHY you believe it is located along this type of tectonic plate boundary.
This area is right in the heart of the alps, and also the location where the Indian plate is crashing into the Eurasian plate. This is a very active tectonic location, and the main reason why the alps are some of the largest mountains in the world.
Magnitude 7.1
Location near the east coast of Honshu, Japan
Date Thursday, April 7
Time 14:32:41 UTC
Depth (where the focus occurred) 49.00 km (30.45 mi)
Determine the basic type of tectonic plate boundary it occur at (i.e. oceanic-to-oceanic, continental-to-continental, oceanic-to-continental, transform, divergent, or intraplate)
Oceanic to continental
Explain WHY you believe it is located along this type of tectonic plate boundary.
As far as I can tell from the map, there is a plate boundary occurring right along the coast of Japan, leading to an oceanic to continental boundary. This is how Japan was initially formed.
Magnitude 4.7
Location east of Dominica, Leeward Islands
Date Sunday, April 10, 2011
Time 23:44:04 UTC
Depth (where the focus occurred) 23.40 km (14.54 mi)
Determine the basic type of tectonic plate boundary it occur at (i.e. oceanic-to-oceanic, continental-to-continental, oceanic-to-continental, transform, divergent, or intraplate)
This is a divergent boundary
Explain WHY you believe it is located along this type of tectonic plate boundary.
In the Atlantic ocean there is a deep ocean ridge that runs all the way east and west, and there are some off shoots which this is a part of, you can see the ridge in the map showing the separation of the plates.
Magnitude 4.3
Location Baja California, Mexico
Date Thursday, April 7
Time, 2011 13:40:59 UTC
Depth (where the focus occurred) 10.00 km (6.21 mi)
Determine the basic type of tectonic plate boundary it occur at (i.e. oceanic-to-oceanic, continental-to-continental, oceanic-to-continental, transform, divergent, or intraplate)
Transform
Explain WHY you believe it is located along this type of tectonic plate boundary.
I believe it is located here because this is a run off fault of the pacific plate moving along the North American plate
Magnitude 5.0
Location 27.171°N, 143.327°E
Date Wednesday, April 06, 2011
Time 07:12:13 UTC
Depth (where the focus occurred) 44.1 km (27.4 miles)
Determine the basic type of tectonic plate boundary it occur at (i.e. oceanic-to-oceanic, continental-to-continental, oceanic-to-continental, transform, divergent, or intraplate)
Oceanic-to oceanic
Explain WHY you believe it is located along this type of tectonic plate boundary.
Because it is out in the ocean, and it is nearby Japan, where a lot of tectonic activity has been taking place recently. So it would make after shocks and other tension within the region heightened for the possibility of activity.
