The document discusses features of earthquakes in circum-Pacific volcanic zones. Specifically, it notes that earthquakes in these zones tend to have epicenters located directly above where tectonic plates collide under the sea. Additionally, large earthquakes often occur in areas where stress has built up. Detailed surveys of the ground can confirm small earthquake activity in regions with accumulated stress. This earthquake mechanism is similar to stress buildup and cracking that occurs when pressing on a plastic sheet laid under paper.

1. Feature of circum-Pacific volcanic zone
and earthquake
I research about Feature of circum-Pacific
volcanic zone and earthquake.

2. The feature of the earthquake of the volcanic
zone in many parts of the world and the feature
of the earthquake in the circum-Pacific volcanic
zone seem almost to be the same.

3. The feature of the earthquake of each volcanic
zone seems to have the epicenter right above
most knocking against of the continent to the
bottom of the sea plate each other

4. and to occur in the place where the stress builds
up especially the large earthquake.

5. I hear that the load hangs to the plate when the
ground is surveyed in detail, and the sign of the
occurrence of a lot of small earthquakes etc.
was able to be confirmed to the region where
the stress has built up therefore.

6. This mechanism comes to have been played
rubber by the a celluloid board laid under
written paper the topknot and constantly

7. and cracks just pressing a plastic a celluloid
board laid under written paper against the palm.

8. This is a mechanism at the earthquake
generation. Continent several at low pressure do
speed move when plate stress open, in a word,
earthquake generate unit forecast become.
