Check for recent significant earthquakes, quakes, or seismic activity anywhere in the world, from the past 7 days, sourced from USGS (US Geological Survey). Answers questions like "was there an earthquake near me", "how strong was the recent quake in X", or "list major earthquakes this week". Optional 'minmagnitude' filters by minimum magnitude (default 4.5), and 'limit' caps the number of results (default 10, max 50).
