Features & Capabilities

The PHIVOLCS FaultFinder Chrome extension provides users with real-time information about their distance to the nearest active fault. It leverages multiple map sources, including the Philippine Geoportal Map, Google Maps, and OpenStreetMap, to display geospatial data accurately. Designed as a web-based Geographic Information System (WebGIS), the extension taps into PHIVOLCS's comprehensive active fault database via web services. Developed collaboratively by the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the Department of Science and Technology (DOST) of the Philippines, and the Geological Survey of Japan (GSJ), this tool aids in seismic awareness and preparedness by offering precise fault proximity details based on user-selected locations or current GPS position. An essential resource for researchers, planners, and residents, PHIVOLCS FaultFinder enhances understanding of active fault zones in the Philippines.

User Reviews

The PHIVOLCS FaultFinder app is praised for providing accurate fault line information and helping users prepare for earthquakes with a lightweight design and good map resolution. However, multiple users report compatibility problems with some Android devices, loading issues with non-Google map layers, UI glitches like unscrollable lists and overlapping text, and the absence of clear tutorials. The app also experiences slow startup and map loading times, detracting from user experience. Overall, while useful and reliable, the app requires improvements in compatibility, interface usability, and guidance to reach its full potential.

Pros

Provides accurate and reliable information about nearby fault lines and earthquake risks.
Helps users prepare for earthquakes by knowing fault line proximity, contributing to safety and awareness.
Lightweight app with good map quality, enabling detailed location viewing.
No unnecessary ads, making for an uninterrupted user experience.
App performance is better compared to the website with reduced waiting times.

Cons

Compatibility issues with certain devices and Android versions, causing the app not to run or display properly.
Non-Google base maps like 'Philippine Geoportal' often fail to load or are blank.
User interface problems such as inability to scroll through location selections and overlapping text, impacting usability.
Lack of clear tutorials or instructions, making it harder for first-time or elderly users to navigate the app.
App startup and map loading can be slow, leading to user frustration.

Recent reviews

I think general public appreciated the gesture behind the app but this app has serious issues concerning access to basic buttons such as (but not only) "Legend" in the extreme right corner, which simply does not work. Red continuous line seems to be Active Fault but what red dashed lines ? What are black continuous lines ? What are black dashed lines ? Also, adding major Trenches in the sea would have been more logical concerning continuity of the tectonic plates.

What is wrong with you guys? I've been using this app ever since the web version stopped working, and then this app also stopped working on my Huawei P20. I eventually found out that it's no longer compatible with my phone. So now, the app just decided to be very picky with devices? I just wanted an informative app to address my concerns about earthquakes and fault lines. Stop risking other people's lives by making your app useless. I might as well switch to other apps at this point.
