WebApr 14, 2024 · Taiwan uses an intensity scale of one to seven, which gauges the degree to which a quake is felt at a specific location. The first earthquake’s intensity registered at 4 in Taitung County and at 1 in Hualien County. The second earthquake’s intensity registered at 3 in Taitung County. WebA 12-point abridged form of the modified Mercalli scale is provided below. Modified Mercalli intensity VIII is roughly correlated with peak accelerations of about one-quarter that of gravity ( g = 9.8 metres, or 32.2 feet, per second squared) and ground velocities of 20 cm (8 inches) per second.
