29) Why is the Richter scale a more useful scale than the Mercalli scale when measuring the strength of an earthquake? ) What do new buildings have to limit the damage caused by earthquakes? __ (These absorb much of the wave motion of an earthquake so the illding sways instead of collapsing). 30) What are 3 steps you can take to prepare for an earthquake?

29) The Richter scale is more useful than the Mercalli scale for measuring the strength of an earthquake because it provides a quantitative measure of the earthquake's magnitude based on seismic waves, allowing for objective comparisons between different earthquakes. In contrast, the Mercalli scale is subjective and measures the intensity based on observed effects and damage, which can vary depending on location and building structures.<br /><br />30) Three steps you can take to prepare for an earthquake are:<br /><br />1. Secure heavy furniture and appliances to walls to prevent them from falling.<br />2. Create an emergency kit with essentials such as water, food, flashlight, batteries, and first aid supplies.<br />3. Develop a family emergency plan, including communication strategies and designated meeting places.
