They're initially 8.5 km apart.

The open space between them is shrinking at the rate of 155 km/hr
from one end, and 155 km/hr from the other end, so the space is
closing at the rate of  310 km/hr.

The open space between them will shrink to zero in

               (8,500 m) / (310,000 m/hr) 

           =           0.02742 of an hour

           =             98.7 seconds

<em>Convert 1nanosecond in to its SI init</em>

<em>In SI units, nano is 1000th part of micro which in turn is 1000th part of mini which in turn is 1000th part of main unit. Now, when you affix nano to any unit, here in case, second, it means that you are referring to 1000th part of 1000th part of 1000th part of second or in short, 1000000000th(10^9) part of a second.</em>

The majority of earthquakes worldwide occur at all but one location. That is
natta225 [31]
Earthquakes occur in the crust or upper mantle, from the earth’s surface to about 400 miles below the surface. But the very deepest earthquakes only occur at subduction zones where cold crustal rock is being pushed deep into the earth. In California, earthquakes are almost all in the top 15 miles of the crust, except in northern California along the Cascadia Subduction Zone, which extends into Oregon, Washington, and British Columbia.(tectonic plate boundaries)
