 recorded a total of 12,911 aftershocks in the month following the main tremor. The earthquake was in an unusual location for Taiwan, which experiences the majority of its earthquakes off the eastern coast, such quakes normally causing little damage. One of the aftershocks, on September 26, was a strong earthquake in its own right, measuring 6.8 on the Richter scale and causing some already weakened buildings to collapse, killing another three people.

Due to an extensive network of sensors and monitoring stations, the quake was the best recorded and analysed large quake in history. At one station, a peak ground motion of 300 cm/s (3 m/s; 10 ft/s) was recorded, the highest ever measurement taken in an earthquake anywhere. Soil liquefaction

Damage

Damage caused by the earthquake included 2,415 deaths, 29 missing, 11,305 severely wounded, with 51,711 buildings completely destroyed, 53,768 buildings severely damaged, and a total of NT$300 billion (US$10 billion) worth of damage. Power was cut to a large proportion of the island, due to damage to power stations, transmission stations, and the automatic shutdown of Taiwan's three nuclear power plants, which were restarted two days later. National electricity provider Taipower stated that a day after the quake power had been restored to 69% of the country. 102 major bridges were badly damaged, with many having to be torn down.

, at the time the only major complete route across the mountains in central Taiwan, was badly damaged. Subsequent storm damage and the high cost of restoration means that the highway remains closed as of 2009 and is not expected to be reopened. There were a total of 132 landslides during the main quake and the aftershocks, some causing loss of life as rockfalls crushed houses. 870 schools suffered damage, with 125 severely damaged, closing many down for months or even permanently in a few cases.

Central Taiwan

The effects of the earthquake were most severe in central Taiwan, particularly in Nantou County and Taichung County. Towns such as Puli

Northern Taiwan

In Taipei City, far from the epicentre of the quake, buildings were shaken, but just one, the 12 stories Tunghsing Building , collapsed as a result of the tremor. 87 people died in the rubble of the building, which was later found to be unsoundly built, with structural pillars and beams stuffed with plastic bottles and newspaper instead of brick and concrete. Blame for the collapse was levelled by survivors at both the construction company which built the high-rise and local government for lax enforcement of building codes and safety standards. Five people were indicted in the wake of the disaster.

Causes of building collapse and public reaction

The immediate rescue efforts were still ongoing when public anger began to mount at shoddy construction that many felt was responsible for the high number of casualties. Legal building codes, enforcement of those codes, and the construction companies themselves all came in for criticism. Builders and architects of modern buildings that collapsed were detained by the authorities, their assets frozen and travel documents seized. One of the issues highlighted after the quake was "soft stories": high, open ground floors in high-rise buildings with little structural support. This led to the ground floor collapsing first in a quake, either toppling the other floors or starting a pancake collapse. Buildings in Taiwan over 50 metres (164 ft) tall require a peer review process; no building that had undergone this process collapsed, contrasting with a number of dramatic failures of buildings just under 50 metres in height.

International response

There was widespread international sympathy for those affected by the earthquake, and over 700 rescue workers from more than 20 countries aided in the immediate aftermath. Initially Taiwan's isolated diplomatic situation caused a delay in a response from the United Nations

Jiang went on to say that "Compatriots of the two sides are as closely linked as flesh and blood. The catastrophe and agony of our Taiwan compatriots influences the hearts of all Chinese." However, after a few days the Taipei government was accusing Beijing of exploiting the earthquake for political ends and preventing speedy assistance from the international community getting to those in need. A Russian flight carrying search and rescue personnel was refused permission to cross Chinese airspace, and the PRC insisted that any approaches to send aid to Taiwan from other nations needed the blessing of the Beijing government first, slowing the arrival of international help.

Rescue efforts

Immediately following the earthquake an emergency cabinet meeting was convened to discuss how to tackle the aftermath. The same day the ROC military was mobilised, with large numbers of conscripted soldiers heading to stricken regions to assist in distributing emergency supplies, clearing roads, and rescuing people trapped in the rubble. Helicopters were used to evacuate injured people from mountainous regions to hospitals, and to supply food to communities inaccessible by road. The military also assumed the leading role in recovering the dead from damaged structures.

One of the last people to be rescued was a six year old boy pulled alive from the rubble of his collapsed home in Taichung County by a team of South Korean and Japanese search and rescue workers, some 88 hours after the quake. Even later, nearly 130 hours after the earthquake, two brothers emerged alive from the ruins of the Tunghsing Building in Taipei to the astonishment of rescuers. The brothers survived on the water sprayed from fire hoses, rotten fruit, and their own urine.

, the reconstruction policies were continued despite the change in ruling party. Chen said in his inaugural address in May 2000 that "our people experienced an unprecedented catastrophe last year, and the wounds are yet to be healed. The new cabinet feels that restoration cannot be delayed ... Reconstruction has to cover every victim and every earthquake-affected area."

One task that had to be undertaken was the setting of new land ownership boundaries in areas where the landscape had been significantly altered by the quake. The whole island was elongated about 1.5 metres (4.9 ft) in the north-south axis and compressed west-east by the forces unleashed. One solution offered to land issues was to offer landowners an equivalent parcel of government land not located on a fault line.
