Depth: median 28.0 km, deepest 61.2 km. Median magnitude 1.84. Average per week over 30 days: 103.8. Tsunami flag set on 0 events (the USGS flag marks events in oceanic regions; it is not a tsunami warning, see tsunami.gov).
How the figures are counted: Events counted: USGS catalog type “earthquake”, magnitude 1.5 or higher, origin time in the 30 days before the data were pulled, location label ending in the state name or its postal abbreviation. Weeks are 7 × 24 hours counted back from the pull time.
Worked example: 445 events in 30 days × 7 ÷ 30 = 103.8 per week on average; the last 7 days had 82.

Why can the numbers differ from other earthquake sites?
Sites differ in the magnitude cut-off, the time window and how an event is assigned to a state. This page counts every event of M1.5 or higher in the USGS catalog whose location label ends in “Hawaii”, for the 30 days before the data were pulled. Small events are detected less completely in some areas, and magnitudes are often revised.
Did I feel it, and where do I report it?
USGS collects felt reports through its “Did You Feel It?” system at earthquake.usgs.gov/data/dyfi. In this list 16 events have at least one felt report, 99 reports in total.
What should I do during an earthquake?
