Both quakes had little effect on the island's chip operations, including major foundries Taiwan Semiconductor Manufacturing Co. and United Microelectronics Corp. They both acknowledged that some wafers are lost in a minor quake, but it's usually a low number.

The quake hit Taiwan in the late afternoon, and originated off the central eastern coast, at a depth of 25 kilometers. In the Hsinchu and Tainan science parks, it registered a 3.0 and 4.0, respectively.

The Monday quake was centered about 25 kilometers off the northeast shore. By the time it reached Taiwan, it only registered 4.0. In Hsinchu it was a 3.0. Chip fabs can handle up to magnitude 6.0 quakes before operations become more severely affected.
