New Zealand Earthquake
New Zealand is located on the Pacific Ring of Fire, which is a region known for the frequent earthquakes. In 2020, the country was hit by a devastating earthquake measuring 7.1 magnitude on the Richter scale. Below, we will discuss the various aspects of this earthquake and why its impact was so severe.
Impact of the Earthquake
The New Zealand earthquake lasted for several minutes, causing significant damage across the country. It struck at the shallow depth of 10 km, which magnified the force felt by people in the region. The quake was felt across the country, but the worst damage was done in the region around Kaikoura and the central North Island. The quake killed two people and thousands of people had to evacuate their homes. Nearly 800 buildings were damaged, eight of which collapsed.
Effects of the Earthquake
The effects of the earthquake in New Zealand were severe and prolonged. There were power outages, landslides, and infrastructure damage. Road and railway damage was so bad that it was said to like a “war had been fought” in some places.
Another major effect of the quake was on the geology of the area. On the South Island, dramatic changes were observed in the seabed landscape due to large landslides. The earthquake also created and activated several fault lines, including the Garvie Fault, whose existence was previously unknown.
Long-Term Economic Effects
The long-term economic effects of the quake are still being felt. Major crops were damaged, and many farms were abandoned due to the extreme force and resulting flooding. Tourism has also been adversely affected, as repair work continues in many areas. The government has taken up the responsibility of reconstruction, but the process is slow due to bureaucratic delays.
Insurance companies are struggling to meet the cost of the extensive damage and the insurers’ resources are taking strain with the high number of claims. Many people are unable to get their claims approved, and thus resorting to other measures for help.
New Building Codes
In response to the quake, the government has implemented new building codes. The goals are to protect the buildings, their inhabitants and the environment from damage due to future quakes. The new codes have been designed to ensure that buildings are able to withstand heavy ground shaking. The codes also regulate building design and specify the use of seismic-resistant material in construction projects.
The new codes are being closely monitored and reviewed to ensure they are being implemented and followed.
The Important Role of Science
Earthquakes, which are a natural phenomenon, are a good example of the importance of science in disaster management. Scientists are leveraging the most advanced technology to predict and prepare for natural disasters.
GPS Technology: GPS technology provides an edge in terms of earthquake prediction and preparedness. The systems are able to track how land moves and how it accelerates in response to seismic activity. This data can help predict the impact of an upcoming earthquake and those who are in the path.
Seismology: Seismology is the study of earthquakes, and seismologists use advanced seismometers to measure the seismic waves produced by earthquakes. The data is used to understand the magnitude and intensity of an earthquake, as well as its likely impacts.
In today’s modern world, geophysical and geotechnical data is being regularly collected and used to determine geological hazards and future disaster risks.
The Role of the Community
The community plays an important role in responding to the New Zealand earthquake. Local emergency services such as fire departments, police, and paramedic services were some of the first to arrive on the scene. They provided essential services such as search and rescue, medical treatment, and emergency shelter.
Neighbourhoods have also come together to support those affected by the quake. Community efforts including donations, fundraisers, and volunteer services have helped communities to rebuild and support those in need.
The 2020 New Zealand earthquake was a devastating event that left a lasting impact on the country. It took lives, damaged buildings and infrastructure, and caused financial ruin. Initial response efforts by local authorities and the community have been successful in providing relief to those affected.
However, there is still much work to be done in terms of clean-up and rebuilding. The new building codes will offer protection for the future, but investments must be made to ensure compliance and implementation. The importance of science in disaster management has also been highlighted and will be key to future preparedness.
