| Is this big enough to produce a Tsunami? Apparently maybe only a small localised one, but I'm supposed to be getting the ferry from Lombok to Bali shortly and two of those have already burnt down the last 2 weeks! |

| ▲ | decimalenough 2 hours ago | parent | next [-] | | A ferry in the open ocean is one of the safer places to be during a tsunami. Remember, it's not a surf-style wave, but a gradual increase in water level. | |
| ▲ | wiml 2 hours ago | parent | prev | next [-] | | I've seen "possible tsunami" pre-warnings, and a sea level gauge at/near Lembar showing sea level oscillations - so I would recommend keeping a close watch on some information source that's better than HN comment threads, yes. | | |
| ▲ | lostlogin 20 minutes ago | parent [-] | | Correct, but also, I’d bet there is a lurking tsunami expert here somewhere. Nothing is ever too niche for HN. |

| ▲ | Grimburger 2 hours ago | parent | prev | next [-] | | Tsunamis are only an issue close to shore. In the ocean it's barely a mild wave. In a boat going further out is the safest thing you can do if there's a tsunami warning. | | | |
| ▲ | bdickason an hour ago | parent | prev | next [-] | | I would upgrade the ferry and make sure to get a high quality one given all the swell in the ocean already (most of bali had 6ft+ waves yesterday) and this incident. Not worth the risk. | |
| ▲ | rootsudo an hour ago | parent | prev | next [-] | | Interesting times for the ferry indeed | |
| ▲ | reilly3000 2 hours ago | parent | prev | next [-] | | Safe travels, friend. | |
| ▲ | pestatije an hour ago | parent | prev [-] | | the tsunami risk is negligible compared to the fire risk |

| I know large earthquakes are effectively random (ignoring aftershocks) but this feels like a lot this year, yeah? |
| |
| ▲ | beloch a few seconds ago | parent | next [-] | | Earthquakes can occur in swarms[1] (distinct from aftershocks), with many occurring in a small area over "relatively short" periods of time (i.e. days, weeks, or years). The USGS map shows the 7.7 quake being followed by about 19 other smaller quakes near or in Indonesia within just a few hours. These are probably aftershocks. ------- [1]https://en.wikipedia.org/wiki/Earthquake_swarm | |
| ▲ | teacpde 2 hours ago | parent | prev | next [-] | | Yea, feel like a lot of big ones this year, but looking it up https://en.wikipedia.org/wiki/List_of_earthquakes_in_2026 it is actually not necessarily worse than previous years. | |
| ▲ | ortusdux 2 hours ago | parent | prev | next [-] | | 76 quakes ranking 7.0+ so far this decade, including 10 this year. https://en.wikipedia.org/wiki/List_of_earthquakes_2021%E2%80... | |

| ▲ | kermatt 2 hours ago | parent | prev [-] | | I was wondering the same: https://www.morageology.com/earthquake_year.php | | |
| ▲ | LeBit 2 hours ago | parent | next [-] | | > Note: While it may look like there have been an increase in total number of earthquakes since about 2020, this is actually due to the increasing number of seismic stations installed in the park since 2020 that are able to detect smaller (<= 0.5 magnitude) earthquakes. If you look at the number of earthquakes >= 1.0, the rate has remained about the same. | |
| ▲ | goda90 2 hours ago | parent | prev [-] | | Why does this page say there have been 0 >2.5mag earthquakes this year? | | |
| ▲ | teraflop 38 minutes ago | parent [-] | | Because this particular sensor network is only monitoring earthquakes in the Pacific Northwest of the USA, not worldwide. |

| So Google Earth says the ocean depth at the epicenter is 6,286 ft / 1,916 m, but I couldn't find a corresponding tsunami alert or evaluation of risk. |
| |
| ▲ | mikeyouse 2 hours ago | parent [-] | | Looks like it was a strike-slip fault, so a much lower tsunami risk compared to a subduction / dip-slip fault. | | |
