hypocenter
◦ the point ____ above the focus on the ____ of the
earth is the epicenter

• how can we find an earthquake’s epicenter?

Explanation:

1. First blank (earthquake type with 8+ magnitude)

Earthquakes with a magnitude of 8 or higher on the Richter scale are classified as "Great" earthquakes, as they cause serious damage over large areas (several hundred km across).

The Modified Mercalli Scale measures earthquake strength based on the observations of effects (like shaking, damage) by human observers. It also assesses the amount of damage to structures built by humans (buildings, infrastructure).

The focus (hypocenter) is the point within the Earth where faulting begins (the initial rupture occurs). The epicenter is the point directly above the focus on the surface of the Earth.

Answer:

Great
