Differences between a 7.1 and a 7.2 Earthquake

An earthquake is defined as a sudden release of energy in the Earth’s crust that creates seismic waves. Earthquakes can range from magnitude 1-9 on the Richter scale, with 9 being the largest. The two most common types of earthquakes are compressional (P) and shear (S). Today we will be discussing the differences between a 7.1 and a 7.2 earthquake.

What is a 7.1 Earthquake?

  • A 7.1 earthquake is a natural disaster that causes severe damage to infrastructure and human life. It is the second strongest earthquake on the Richter magnitude scale, and typically only occurs in areas with high tectonic activity.
  • 7.1 earthquakes are often followed by aftershocks, which can add to the destruction caused by the initial quake. In terms of human death tolls, 7.1 earthquakes are some of the deadliest natural disasters, with an estimated 2,000 people killed in the 2010 Haiti earthquake.
  • In terms of economic damage, 7.1 earthquakes can cost billions of dollars in repairs and rebuilding. They often result in widespread power outages, transportation disruptions, and water shortages. 7.1 earthquakes are a reminder of the power of nature, and the need for humans to be prepared for when they occur.

What is a 7.2 Earthquake?

A 7.2 earthquake is a very powerful quake that can cause extensive damage to buildings and infrastructure. This level of an earthquake can occur when two plates collide, causing the Earth’s crust to rupture. The force of the 7.2 earthquakes can be destructive, and people in the vicinity of the quake should take cover immediately. Earthquakes of this magnitude are often followed by aftershocks, so it is important to stay alert and be prepared for further shaking. In the event of a 7.2 earthquake, it is important to stay calm and follow the instructions of emergency personnel. By doing so, you can help to minimize the damage caused by this natural disaster.

Differences between a 7.1 and a 7.2 Earthquake

A 7.1 earthquake is about 10 times bigger than a 7.0 earthquake. The difference in shaking between a 7.1 and 7.2 quake is approximately the same as the difference in shaking between a 6.9 and 7.0 quake. A 7.2 quake produces very strong shaking: it can break windows, damage weak buildings, and cause moderate to heavy damage to well-built buildings. A 7.1 earthquake can also cause tsunamis in coastal areas if the epicenter is located offshore. A 7.2 earthquake is considered a major earthquake and can cause widespread damage and loss of life.


The difference between a 7.1 and 7.2 earthquake is significant, and it is important to be prepared for both. While the probability of a quake that strong happening in any given year is low, it’s still important to have a plan in place in case one does strike. If you live in an area that could potentially be affected by a major earthquake, make sure you are familiar with the warning signs and what to do when an earthquake hits.
