This earthquake was originally reported as a magnitude 4.6 but was downgraded to a magnitude 4.3.
Remember, there is a trade off between speed and accuracy. As more data becomes available the initial reports are likely to be adjusted to reflect our improved understanding.

During a tsunami warning we always caution that a tsunami arrives as a series of waves and the first arrival is not always the largest. Larger tsunami arrivals can occur hours later. We can see this from the recent M 8.8 Kamchatka earthquake.🧪
